In the midst of Claude Code’s meteoric rise, his code has been leaked. It is a sweet treat for its competitors

by

One of the news of the day is the great code leak that it has suffered Claude Code. The entire architecture of the programming tool of Claude has been leaked, due to an internal error recognized by Anthropic. Your competitors are in luck. what has happened. The leak was not the result of an external attack or a hack, it was an internal failure: when publishing one of Claude Code’s updates, a 59.8 MB JavaScript source code map (.map) file was exposed, intended for internal debugging. According to sourceswas included by mistake in version 2.1.88 of the @anthropic-ai/claude-code package published this morning. Minutes later the party started. “Earlier today, a release of Claude Code included some internal source code. No sensitive customer data or credentials were involved or exposed. This was a release packaging issue caused by human error, not a security breach. We are implementing measures to prevent this from happening again.” The consequences. For the next few hours, the more than 500,000 lines of leaked code were accessible and downloadable from a public GitHub repository. Since its publication, there are already more than 50,000 forks of the code. The leak shows the system of internal tools that the AI ​​uses to operate and, in addition, signs of functions that have not yet been released have appeared. This has allowed us to have in-depth access to the current anatomy of Claude Code, the internal plans for subsequent iterations and the main limitations it currently has. Why is it important. Although not Claude’s own model has been leaked, but rather the source code of his Code tool, the leak is a double blow for Anthropic. First, it is a severe setback for the company’s intellectual property, handing over its roadmap not only to competitors, but to actors eager to break Claude Code’s security barriers. More importantly, it is a blow to a company that since its inception has focused on being even safer than its competitorspublicly admitting that a file has been slipped in that should not have seen the light of day. What Anthropic has done about it. Anthropic’s reaction has been quick, removing the affected package to prevent new downloads and correcting the subsequent version. Despite this, the damage was done and the situation is irreversible. Go deeper. Claude Code has become, in its own right, one of the most popular tools among developers. According to data from SemiAnalysis, 4% of all public commits uploaded to GitHub are created with this tool, and it is expected to reach 20% in 2026. The Claude Code leak is a reminder that even the most advanced AI companies are not free from rookie mistakes. In Xataka |

the four day week

by

In Norway, leaving the office at three or four in the afternoon is neither a privilege nor an exception: it is the normal schedule for millions of workers. According to the Active Population Survey of Norway, the standard day in Norway It is around 37.5 hours per week distributed in shifts of 7.5 hours per day, and the real average is around 33.6 hours, which places the country among the developed economies. with fewer hours worked. Yet even with that enviable starting point, Norway is questioning whether the five-day-a-week model still makes sense. The response that is taking shape points towards the four-day week, not as a utopia, but as an ongoing experiment with scientific data behind it. A country that works little and produces a lot. In the Norwegian labor market, the idea of ​​working efficiently within a limited schedule predominates. As described by Carla, a Spanish resident in Norway in one of his videos on TikTok: “Most Norwegians have my perfect work schedule, 8 a.m. to 4 p.m., because it gives them plenty of time to do afternoon activities and spend time with family.” Far from hampering the economy, this commitment to conciliation coexists with productivity levels per hour worked among the highest in Europe. According to OECD data Norwegian employees accumulate 1,412 working hours per year, compared to the OECD average of 1,740. For its part, unemployment in 2025 was around 4.7%, according to data of Eurostat. Generation Z wants to go further. It is precisely the youngest workers who most strongly question the inherited model. According to the survey ‘Empowering Minds’ from YouGov, the invisible mental load derived from planning, anticipating and coordinating so much at work like at homeweighs especially on the younger generations in the Nordic countries. Raised in hyperconnected environmentsGeneration Z does not see the four-day week as a luxury but as logical evolution of smart work. And they have arguments to support it. A Deloitte survey to more than 23,000 young people reveals that the balance between life and work is the top professional priority of Generation Z, above the career progressionand that only 6% aspire to reach a leadership position as their primary objective. For this generation, working well is not synonymous with work more. The Nordic model has cracks. The problem is that this model, despite its virtues, has not managed to protect Norwegian workers from stress. The out of hours notifications and instant messaging have eroded the boundaries that Norwegian work culture had so carefully constructed, and sick leave due to mental disorders has continued to grow according to the official discharge records due to illness. It is in this context where the four-day work week ceases to be a union demand to become an alternative worth considering. If having a shorter than average day already improves the well-being of Norwegians, reducing an entire day could be the lever Norway needs to stop the deterioration of mental health of its workers. Productivity and well-being in four days. In 2024, the first Norwegian pilot program four-day work week. Eleven companies from sectors as different as hospitals, municipal services and consulting firms participated for six months under the 100:80:100 model (100% of the salary, working 80% of the time, with the objective of maintaining 100% of productivity). Same model they have followed other projects four-day workweek in the world, including that of Valencia in 2023. The Norwegian experiment was monitored by the consulting firm The Rework in collaboration with Karlstad University and Boston College. The results collected in the official report that have just been made public, show that this day model combines the best of both worlds. Stress was reduced by 19%, participants went from sleeping 6.6 hours a night to 7 hours, and satisfaction with time for personal activities grew by 44%. All of this occurred while perceived productivity increased by 13%. Of the ten participating companies that shared their business results, five recorded improvements and another five maintained the same levels of productivity and profits as before the experiment. That is, none of them worsened their performance by reducing the working day. In fact, the results were so satisfactory that ten of the eleven companies they decided to continue with the week reduced at the end of the test.

In the middle of 2026, a childhood without mobile phones sounds impossible. A town in Ireland is doing it

by

Greystones is a small town on the coast of Ireland, more specifically in County Wicklow. 22,000 inhabitants, semi-detached houses, coastal landscapes, a railway network which allows you to reach Dublin in just over half an hour… A priori, it is the perfect town to enjoy a peaceful life just a stone’s throw from the bustling Irish capital, where companies such as Google or Apple. However, in recent years the town has been in the news for another, very different reason: his crusade against the use of smartphones among the children. His case shows that it is still possible to live a cell phone-free childhood. What has happened? That the small town of Greystones (Ireland) has strived to teach the world a lesson: to show that in 2026 it is possible to keep children away from mobile phones, Instagram, TikTok and the rest of social networks. We just need to join forces to change the sign of social pressure. The initiative is actually not new. Greystones launched their crusade in 2023when it already aroused the curiosity of the rest of the world. However, the unknown remained as to how the experience would turn out. Now we already know. Where does the idea come from? The debate around what age Children should start using mobile phones or social networks and the influence that these have on them is not new. It’s not a concern unique to Greystones, either. There however it happened something interesting during the pandemic. When students returned to classrooms after lockdown, Rachael Harper, headteacher at St Patrick’s School, found that some children were having trouble sleeping or struggling to concentrate. She wasn’t the only one to notice. Other colleagues confirmed that they perceived similar attitudes among their primary school students. What caused them? It didn’t take long for teachers to focus on the use of cell phones. They even encountered children who controlled their calories with apps. Eoghan Cleary, a teacher at another Greystones school, also found that his students admitted seeing violent content on the Internet. The sum of all these factors led several primary schools to send a survey to around 800 parents When asked about the topic: more than half acknowledged that they noticed their children were anxious. In some cases they had even sought professional help. It was enough for the city to decide to make a move. What exactly did he do? We mentioned it before: join forces. Eight primary schools in the Greystones and Delgany area came together to launch an initiative they named ‘It Takes a Village’ (‘It takes a whole village’). Its main tool was the ‘voluntary code without smartphones’, a community pact that basically encourages residents to prohibit children from using mobile phones during their primary education period. In practice this is equivalent to keeping young people away from networks and smartphones until they turn 12 and enter secondary school. The pact is of course voluntary, free and failing to comply with it does not result in fines, but the idea is that whoever signs it applies it both at school and at home. Were you that worried about the issue? It seems so. “As principal of St. Patricks Elementary School I have observed growing concern among parents and teachers,” Harper admitted in 2023 in a column opinion published in Guardian. “The level of anxiety of children in schools has grown steadily, since easy access to online and mobile content has become a threat to childhood. We felt the need to act. The process started with a realization: childhood is becoming increasingly shorter.” Has it worked? That was three years ago. Now we finally know how the initiative is working. Recently The New York Times dedicated an extensive report in which, among other issues, it confirms that the campaign has had a more than reasonable reception. They have supported her 70% of parents and above all it has penetrated the town, moving to businesses and politicians. He has even made his mark beyond Wicklow. Shortly after it was launched ‘Smartphone Free Chilhood’a citizen movement that advocates delaying children’s access to smartphones at least up to 14 years. How has he achieved it? In 2023, Harper herself insisted in that, if it really wanted to work, the initiative had to go beyond the classrooms. “It’s not about enforcing a code. It’s about building a strong network of services that helps children, families and teachers deal with anxiety-related challenges.” The report of The New York Times suggests that goal is also being achieved at Greystones. Beyond what parents do at home, the campaign is completed with training workshops and events such as phone-free beach parties. Even with the commitment of local businesses. For example, one store has offered to help children who need to locate their parents. Is it so important? Yes. And for a simple reason. The very name of the initiative (‘It takes a whole village’) makes it clear that, to succeed, the campaign must play with collective pressure. And it seems that he is achieving it. “In networks everything is collective. Addressing it jointly is the best option,” recognize Jennifer Whitmore, member of the Irish parliament and mother in Greystones. In other words: delaying a child’s access to mobile phones and social platforms is very easy when they are surrounded by other kids of the same age who also do not use them. “What Greystones demonstrates is that parents and communities are not powerless,” agree Clearly. Is it that dangerous? Harper insist in that the initiative is not based on “anti-technology stances” nor does it want to deny children the use of smartphones. The key lies rather in rethinking the times and what it means to have a mobile phone. “Our goal is to ensure that they are adequately prepared and emotionally capable to take on the responsibility that comes with having a smartphone when accessing secondary education”, claims before citing a UNESCO report that suggests it can take up to 20 minutes for a child to concentrate … Read more

Neither drones nor missiles nor AI, the war in Ukraine has turned a vehicle from 1950 into a key piece: the M113

by

Some of the most produced military vehicles in history exceed 80,000 units manufactured and remain in service in dozens of countries decades after their design. In many cases, their longevity is not due to their power, but to something much simpler: that they simply work, are easy to repair, and never completely disappear. An unexpected veteran. While the algorithms and drones freelancers starred on all the covers of war innovationsin recent times the war in Ukraine has turned in key piece to a vehicle from the 1950s as it was the M113and that says much more about the conflict than any next-generation system. On a battlefield dominated by advanced technology, this armored transport has resurfaced not because it is the most powerful, but because it fits better than anyone else in a war of attrition where the important thing is not sophistication, but the ability to resist, move and continue operating day after day. Simple wins. The M113 was designed for another timebut its qualities (mobility, mechanical simplicity and ease of production) make it have converted surprisingly effective in Ukraine. The reason: in an environment saturated with drones and artillery, where any vehicle can be destroyed in seconds, the key is not so much to survive everything as to be able to be repaired quickly and return to the front. Its ability to operate off-road, transport troops or even drones and adapt with improvised protections makes it a versatile tool in a conflict where conditions are constantly changing. Drones and the rules. The truth is that the proliferation of drones has reduced the usefulness of many traditional systems, including heavy tanks, forcing both sides to rethink how they move and fight. In this context, the M113 does not stand out for its weapons, but for its logistical function: carry soldiers, equipment or drones to forward positions. War, from that perspective, is no longer decided so much by direct fire, but by who manages to best position their resources in an environment monitored from the air, and there this vehicle fits perfectly. Russian “Giga Turtle” captured by Ukrainians Meanwhile, Russia adapts in its own way. On the other side of the front, in recent weeks Russia has attempted to respond with radically different solutions, such as the return of called “giga turtle”in essence, over-armored versions of tanks designed to resist drone attacks. Huge and slow, these machines prioritize protection over mobility, making them easier targets despite their toughness. His reappearance reflects the same conclusion that has been imposed on the battlefield: vehicles are still necessary, but they must adapt to a constant threat from the air. War of attrition and quantity. Ultimately, the success of the M113 It also has to do with something much more basic: that there is a glarge amount of stock available for these models. Thousands of units produced over decades allow Ukraine to quickly replace losses in a war where attrition is brutal. In other words, compared to more expensive and scarce modern systems, this vehicle offers something essential for the fight: continuity. In an extremely slow conflict that is already measured in years, it is not whoever has the most advanced weapon who wins, but whoever can continue fighting the longest. The real change is conceptual. If you like, all this points to a deeper conclusion: the war in Ukraine is not necessarily rewarding the newest, but rather the most useful in an extreme context. AND the M113 symbolizes this change like few others, where cutting-edge technology coexists with solutions from another era that they still work because they respond better to the real needs of combat. In a scenario dominated by drones, sensors and constant fire, the key is not so much to reinvent warfare, but to adapt to it, even if that means returning to vehicles designed more than half a century ago.

How to convert GPTs or Gems into Claude Skills in case you want to migrate your ChatGPT or Gemini customizations

by

Let’s tell you how to convert GPTs or Gems into Skillsso if you want to go from ChatGPT either Gemini to Claude you can take the automated versions of your artificial intelligence. And if you are going to change, remember that you can too migrate memory of everything other AIs know about you. The Claude’s Skills They are a series of instructions that you can upload to a chat so you don’t have to repeat them every time you want to do something specific. They can be very complex, although we will teach you how to migrate the GPTs or the Gems simple, those that are simply instructions. Convert GPTs or Gems into Skills The first thing you have to do is enter ChatGPT or Gemini and go to the GPTs or Gems section. Once inside, you have to click on the edit button of the GPT or Gem that you want to convert into a Skill. This will take you to a screen where you can see the name, description and instructions of the Gem or the GPT. These are the data that we are going to use later, so keep the window open. Now what we are going to do is create a Claude Skill with that data. For that you must open Claude, and within his website you must go to section Personalize from the left column. Inside, click on the section Skillswhere you will be able to see all the pregenerated ones that the AI ​​has already created. You will enter the Skills page, where by default you will see several examples of those created within Claude himself. Here, click on the + button above, and in the menu that opens choose the option Write the instructions for the skill to make it easy. This will open the field where you have to enter the name of the skill, the description and the instructions. Copy and paste the description and instructions of the GPT or the Gem so that the skill is similar, and then put the name you want, which can also be the same. One of the peculiarities of the Skills is that Claude will review them every time you ask him for something to use them automatically without having to attach them in case what you want corresponds to what the skill is capable of doing. That’s why, you can add to the instructions the request that he not do thisthat it only uses the skill if you explicitly ask for it or if it is added. And that’s it. What was once a simple GPT or Gem is now a simple Claude Skill. Now you just have to choose it from the menu from Claude’s new chat. You will have to press the + button, go to Skills, and choose yours. Once you have it selected, you just have to add the text you want, and Claude will process it according to the instructions of the skill you have loaded.

The Artemis II countdown has already begun, but many critical points must still be overcome

by

If everything goes well, humans will return to the moon todayafter more than 50 years without manned trips to our satellite. The Artemis II mission has a two-hour launch window, which will begin at 6:24 p.m. local time in Florida (00:24 a.m. PST). Before that launch the countdown will take place. But not the typical 10-second countdown that comes to mind, but a much longer one that has, in fact, already started. During the 50 hours that the countdown lasts, each of the factors that could make it necessary to postpone the launch are analyzed point by point. Only if everything is fine or can be solved at the moment will we finally see this mission begin, which breaks records and barriers in many ways. Who. The crew of Artemis II They will be very different from those of the Apollo missions. Although all of them were crewed by three white American men, this time there will be more variety. The four astronauts who will go aboard the Orion capsule are Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen. The last three will be the ones that will make the difference, since Glover and Koch will potentially be the first black person and the first woman to travel to the Moon and Hansen the first Canadian to leave Earth’s orbit. The Artemis II crew will be pioneers in many ways So that. Artemis II will not land on the lunar surface. That will be the goal of Artemis III. However, its 10-day trip will include a flyby to the Moon, in which key systems, such as life support, navigation and communications, will be tested. Photographs will also be taken of the hidden side of the Moon, in order to analyze its geology. and other data of scientific interest. Meanwhile, astronauts will carry sensors that will help verify the alterations that their biological parameters experience in space. The countdown. While it is true that the true countdown lasts 10 minutes, during the 50 hours prior to launch There is a very well established testing and preparation schedule. It all starts with preparing the fuel loading systems and powering up the ship. Other important key points are, for example, the ignition of the batteries, which occurs 33 hours before or the cooling and subsequent filling of the various fuel charging and propulsion systems. These steps are taken starting 10 hours before launch. Also very important is the flight crew’s weather briefing, which takes place 6 hours before the rocket is launched. The real countdown. During the last 10 minutes, very sensitive tasks for the launch are carried out. Above all, in this countdown the last checks are made to all the systems and the refueling of the fuel tanks is carried out. This means that the tank is refilled to the optimal level to replace the fuel that has evaporated during the filling stages. In these last minutes, the final pressurization of the tanks is also carried out and the rocket goes into internal energy mode. That is, it stops using energy from the terrestrial electrical system and uses only its batteries. What can go wrong. Any minor detail that does not work properly during the 50 hours before launch could cause the mission to be postponed. The most sensitive points are, without a doubt, those that have to do with fuel. For example, many missions have been canceled when leaks were detected in the tanks that could not be solved at the time. Adverse weather could also force the launch to be delayed. When. A launch cannot take place at any time. The Earth revolves around the Sun and the Moon orbits the Earth. In order for a rocket launched from Earth to follow a suitable trajectory towards the Moon, it is important that it be in a suitable orientation, taking into account their respective orbits. These specific moments are known as launch windows. Artemis II will have one of these windows today for two hours. If the launch could not be carried out due to any error, this month there will be several more opportunities, on April 2, 3, 6 and 30. After takeoff. The first 8 minutes after takeoff are critical. The engines are working at maximum power to leave the Earth’s atmosphere and arrive, now, slowly. Above all there will be two critical ignitions in the rocket’s upper stage, known as ICPS. The first serves to stabilize the orbit and the second to take the rocket to high Earth orbit. It is important that these go well so that the mission can move forward. Once those critical 8 minutes have been passed, the mission will have a lot of flight ahead of it, but at least the most complicated part will have passed. Even so, still We will have 10 days to closely follow the work of these 4 astronauts which, of course, have already gone down in history.

What you can do with MiDNI and what things you cannot do with the Electronic DNI app on your mobile

by

Let’s tell you what you can do and what you can’t do with the Electronic DNI on the mobile. As of April 2, 2026, the application of MyDNI It is mandatory acceptance. This means that It will have the same value as the physical DNI to identify you. In this way, if we have left our ID at home we will continue to be able to identify ourselves and prove our identity in person from our mobile phone. However, There are some things you can’t do with this system, and we are going to tell you them along with those that you can do. What you can do and what you can’t What is the ID used for on the mobile? why the ID is not useful on the mobile Prove our identity in person when there is an internet connection. Prove identity in person when there is no internet connection. Establish any type of legal relationship in person. Prove our identity through the internet. Sign deeds before a notary in person. Use it for border crossing as an electronic travel document. Prove our identity in face-to-face procedures in the public administration. Prove our identity in other countries, with or without an internet connection. Carry out in-person administrative procedures in public or private Universities and Teaching Centers. Carry out telematic procedures that require authentication and/or electronic signature. Prove our majority in person. Exercise our right to vote. Open a bank account in person. Formalize insurance of any type in person. Check into a hotel in person. Rent a vehicle in person. Buy tickets or nominative tickets in person that require identification. In-person commercial transactions in which they ask us for a valid DNI or to prove our identity. Carry out access control to buildings in person. Access entertainment venues such as cinemas, theaters or concerts. Parcel collection. Withdrawal of medications from pharmacies. As you can see in our table, the first thing to keep in mind is that to use the MiDNI app you will need an internet connection. It is an essential requirement, because if you do not have the connection you simply will not be able to access the DNI and you will not be able to show it. For the rest, the electronic DNI on the mobile phone basically serves to prove your identity in all face-to-face procedures. The idea is that teaching it is the same as showing the physical DNIwhich has exactly the same usefulness, and all establishments are obliged to accept it. There is one exception, and that is you cannot use MiDNI to vote. The idea is that it would be valid to prove our identity when voting in elections, but this implementation has been canceled for the moment. Come on, it’s still too early to know if it is 100% effective in identifying us, and to avoid problems, being able to use it to vote has been postponed. Otherwise, You cannot use it in online procedures either.for this you already have other methods like your digital certificateincluding the FNMT certificate and that of DNIe. You can’t use it in other countries either.neither to identify you within them nor to do so at border controls. The MiDNI app is a standard for Spain, but it is not valid outside our borders.

We thought the marathon was heartbreaking. The largest medical follow-up to date has just settled the debate

by

When an amateur runner crosses the finish line after 42 kilometers, his body is on the limit, and so is his heart. This is something that can be seen in a simple analysis where it is seen how the levels of troponin T, one of the warning markers of a heart attack, and evident fatigue in the right ventricle. But in this case the question is obvious: Can doing a marathon kill us? The answer It’s no. This has been demonstrated by an exhaustive study published at the end of 2025 in JAMA Cardiology, which has pointed out that, despite the extreme stress on the heart in the short term, amateur marathon running does not cause long-term cardiac damage. To understand the magnitude of this discovery, we must return to the origin of fear and here recent works, such as those published in Frontiers in Physiology or studies on ultramarathon runners, have documented repeatedly what happens immediately after the race. What has been done. Logically, the effort of doing a marathon at a high level of effort induces morphological and biochemical ventricular changes. The heart here is subjected to a great overload of volume and pressure, releasing proteins that in a patient at rest in the emergency room would set off all the alarms for a possible heart attack. But to draw conclusions, the research has followed the same runners for ten years. The Be-MaGIC project. With this premise, the investigation was not born yesterday, but rather the team took advantage of the historical cohort of this project that originated in the 2009 Munich marathon. In this way, the researchers decided to follow 152 amateur male runners with an initial average age of 43 years. In this way, participants were evaluated before the marathon, after crossing the finish line, one day after, three days after and finally ten years later. To do this, state-of-the-art 3D echocardiography was used and also the analysis of cardiac biomarkers to determine how the ventricles function, which are ultimately the main pumps of the heart. The results. After all these years, studies indicated that, after completing the race, all cardiac function began to be greatly altered with increases in cardiac biomarkers. But this is something that was resolved in the following days until he reached the age of 10 with a completely perfect heart. No scarring of heart tissue, no premature heart failure. Everything is normal, despite the fact that after the race the stress to which he has been subjected is very high and can cause concern. What does this mean? The scientific study confirms that the human heart is an extraordinarily elastic machine. Here, right ventricular dysfunction and troponin release after running 42 kilometers should be interpreted as a transient physiological response to extreme exercise and not as permanent pathological damage. Of course, this doesn’t mean that marathon running is without acute risks, especially for people with underlying or undiagnosed heart conditions. However, for the average amateur runner who trains properly, the science is clear: crossing that finish line will exhaust your body, but it won’t mortgage the future of your heart.

Renfe, Iryo and Ouigo raised prices wildly in 2025. Now they are suffering the foreseeable consequences

by

Demand on trains has fallen. We could think that it is the direct consequence of railway chaos that has set in in the first months of 2026. But no. The last quarter of 2025 already anticipated turbulent times for high speed. And between October and December 2025, prices skyrocketed and demand fell. Now it is the operators who have to walk a tightrope. What has happened? That demand for high-speed trains has fallen significantly in recent months. According to data from Trainlinetrain ticket price comparator, the demand for these trips plummeted 30% after the accident in Adamuz (Córdoba) in the middle of last January. The data could indicate a distrust among travelers as a result, but not everything is explained by the possible fear that those who travel by train may have. And the volume of travelers at the end of 2025 had already fallen. It is something we know now with the publication of the latest report from the CNMCwho collects market movements with a quarter delay or so. Madrid-Barcelona. The consequences in this report are clear, the volume of travelers fell between October and December 2025 in the Madrid-Barcelona corridor, where prices have settled and there is a smaller difference between companies. According to the CNMC, the main data are the following: Decrease in travelers of 13% compared to October-December 2024. Fall of the companies with the most expensive prices: -19% Renfe (95.58 euros) and -13.9% Iryo (76.89 euros). Rise of Ouigo (+12.8%) which has the cheapest prices (61.42 euros). The recorded data shows a brutal increase in prices. Renfe has been left without AVLO to fight for the floor price, which has triggered its average ticket but Ouigo and Iryo also multiplied the price of the average bill. In fact, the following increases were recorded compared to the previous year: Renfe: +40.2% Iryo: +69.0% Ouigo: +40.9% (Much) more expensive, less travel. The increase in prices in Madrid-Barcelona explains several trends: This broker is the least sensitive to price variations. Although the volume of passengers has been reduced, the increase in price has been much greater, so it is to be assumed that there are many travelers who continued to use it as round-trip transportation during the day for similar situations. The operators have finally had to raise prices to stop making losses. This has meant a reduction in passengers on Renfe (which, as we said, You no longer have AVLO service) and Iryo. Ouigo has grown by 12.9% but its places offered have also grown by 16.1%. In the rest of the corridors, only the Valencian has had a substantial price increase (+22.3%) and it has not suffered. Madrid-Seville (-1.9%), Madrid-Málaga (-5%) or Madrid-Alicante (+6.6%) have remained at similar prices. None of these corridors have lost travelers. What can we expect? A drastic drop in the volume of travelers. That is what we expect from the next CNMC report in which the results for January, February and March 2026 will be noted. There are many reasons that explain the result we expect. To begin with, the railway chaos that Spanish roads have become since the fateful Adamuz accident: The most affected. We already know that demand for trains has to fall irremediably given the cuts and speed restrictions that were recorded in the following days, but we must bear in mind that passenger confidence has been eroded since the accident. And not only because of a lack of trust in security, the problem is delays and inconsistency in arrival times. According to ABC65% of the trains arrived late last February. But it is that The Madrid-Barcelona corridor has been the most affected since clients relied on their Swiss punctuality for business trips. That has been diluted in recent weeks, with speed restrictions that are now permanent and road works. This has triggered air travelers, skyrocketing the price the same to the point that Iberia capped the prices of the Air Bridge at 99 euros. It remains to be seen if the companies’ alternative has been to lower prices. We will know that when the next CNMC report arrives and we can have a complete picture of how the market behaved and how operators dealt with these inconveniences when they were already rubbing their hands to raise prices.
