Tesla was a transatlantic for Wall Street. Elon Musk’s political adventure the iceberg that almost sinks with his fortune

by

Tesla has been synonymous with Innovation and success In the electric mobility sector, with an admired brand image and a privileged position in the stock market. The Apple of the automotive, Some qualified it. However, Elon Musk’s foray into American politics has triggered a series of events that have put both reputation and reputation in check The financial results of the company. Musk’s political experiment It has had consequencesdirectly affecting public perception and Tesla’s sales. The destination of Tesla and that of his CEO go hand in Your personal fortune. Tesla before Musk politicization. Before Elon Musk got involved actively in politicsTesla was considered one of the world’s great technological companies and with potential for exceed billion dollars In stock market capitalization. The company was rubbed by giants such as Apple, Microsoft and Amazon, and its Growth seemed unstoppable Thanks to the confidence of investors and the growing demand for electric vehicles. In that scenario, Musk’s personal fortune also reached record figures, exceeding the second time the roof of 300,000 million dollars. Tesla was seen as a safe bet for its investors and its founder was generously rewarded for it. Elon Musk arrived sweeping everything in politics. Elon Musk’s politics landing divided the opinions of investors among whom he thought that his positioning together with Trump (openly contrary to electric cars) would provide strategic advantages to Tesla, and those who saw the brand the brand endangered. For a while, the euphoria of the markets for the change of government gave wings to the company’s actions that marked records after day, while Musk’s fortune shot overcoming the 420,000 million dollars. The panorama changed radically after the elections and Musk’s role at the head of the Government Efficiency Department (Doge). The Tesla reputation He quickly deteriorated when the new department began applying unpopular measures and Musk became the “demolition ball” of the State, As described The Financial Times. Musk and Tesla are one. The image of Tesla is closely tied to that of Elon Musk, so when Musk’s popularity collapsed, he dragged with Tesla, plunging her into An unprecedented reputational crisis. The company sales 13% fell in the first quarter of 2025, while revenues were reduced by 9%, up to 19,335 million dollars. The net profit sank 71%, leaving only 409 million dollars. From the financial crisis of Tesla there are not even those buyers who have decided to sell their Tesla in 2025, who have seen how, due to the reputation of their CEO and the largest number of teslas put up for sale, its price is being depreciated In the second -hand market. Musk’s popularity (lost). A recent survey performed by CNBC He has revealed that 47% of respondents have a negative opinion of Tesla, while 27% maintain their positive opinion of the manufacturer. Its CEO moves in very similar percentages with 50% of negative opinions and 36% of respondents who give them their support. However, as Micah Roberts, a partner of Public Opinion Strategies, the republican pollster who carried out the study, “where Tesla is stronger is among the people with less likely to buy an electric vehicle”, so those who support the political position of their CEO, will probably never be customers of the brand. Tesla forced retirement. Before the collapse of the results and the pressures received From the Republican bench and by investors of Tesla, Elon Musk has recognized in an evening that has not dedicated enough time to the company. In the presentation of results he has promised reduce “significant“His political involvement from May to get the brand out of the problem in which he himself has put it. In a few months, Musk’s fortune has experienced the same ascent and fall as Tesla. Although the value of its actions in the company has decreased considerably, the Impact on your heritage personnel have been damping by the Spacex growth and of XAI, your AI company. If it weren’t for good performance of these companiesTesla’s debacle would have had even more serious consequences For Musk’s richness, which is currently maintained at the same levels That when everything began.

For some reason, there are people trying crash against a wall. Makes more sense than it seems

by

A Tesla Model and, a wall that simulates a road, a youtuber of 65.8 million followers, its reputation. The reputation of Tesla, its security systems and semi -autonomous driving. Another YouTube. A cybertruck tesla. Another wall with another painted road. Indeed, there are people by throwing their tesla against a wall: what is happening? The coyote game and the roadrunner. “I am in my tesla at 64 km/h with the activated highway launched against a false wall in the style of the coyote and the roadrunner.” This is how it starts Mark Rober’s videoknown NASA engineer with a YouTube channel in which 65.8 million subscribers are counted. Rober travels in his car thrown against a false wall in which he has simulated that the road on which circulates continues and perfectly simulates what it really is: a decoration. The objective is to check if your Tesla Model and equipped exclusively with cameras offers better or worse performance than a car equipped with a Lidar system As far as autonomous driving systems are concerned. The background. Rober uses his video to explain the differences between a car that bases its semi -autonomous driving in the cameras exclusively and those that use the Lidar system. In 2021, Tesla already advanced that would base its entire system of driving aid in the cameras. In 2022 it was confirmed that the company would stop riding radars and sensors. The company ensures that its software is able to analyze everything that happens exclusively using cameras with reliability that matches that of radars and sensors. Along the way, evidently, the cost of assembling these components that irremediably increase the final cost of the vehicle is saved. To check if this is true, Rober tests A Tesla Moder and that only uses cameras In its Autopilot system and a lexus RX equipped with a lidar sensor of the luminar company. The cars are launched with activated semi -autonomous driving functions (Autopilot in the case of Tesla and adaptive cruise control in the lexus) to verify what happens in different scenarios. Among them, children who appear in the trajectory of the car or very intense rains. The wall. During his tests, the vehicle equipped with Lidar December and saved a child from being hit if he was already on the road, if he appeared behind an obstacle, in cases of fog and intense rain or if he was dazzled by an intense light. And yes, also if there was a wall on the road painted with the simulation of a road. The Tesla Model and could not say the same and the cameras did not exceed the tests of the fog, the rain … and the famous wall. In the latter case, the car was cheated and thought that the road continued, not stopping at all. And has exploded the controversy. The video Mark Rober has exploded the controversy on social networks for various reasons. The first and most obvious: does this type make sense? When can a car find a wall that completely covers a road simulating that it continues later? Beyond that this has to value each other, what is true is that Rober activates the highway a few seconds before reaching the wall and in the video it is observed how the system is disabled when it is going to collide. Rober has been accused of turning off the system but has defended himself on social networks publishing a complete video in which it is seen how the system is disabled before the crash. A criticism that has been repeated To Tesla vehicles, accusing the company of washing their hands before the authorities. But not only that, Rober has also been criticized for using a vehicle with autopilot and not with Full Self Driving (FSD)the most advanced autonomous driving system in Tesla while Lexus was equipped with Lidar, one of the most expensive technologies at the moment. Cameras vs lidar. The experiment has something interesting although not a resolution. The truth is that one might expect that a cameras based system is less effective than one accompanied by a lidar. The single combination of mounting a camera and a radar has been demonstrated The most effective option So far both day and night. The cameras analyze with images what they have in front but a lidar sends pulses of light constantly around them. That light bounces on the object and returns to the lidar. With the time that has passed since the shipping of the pulse of light until it receives it again you can create a 3D map that, in the case of the wall, serves to verify that there is an obstacle on the road even if it can deceive the camera. Autopilot and FSD. The other great criticism that has been made to Rober is that he uses a car equipped with Autopilot but not with the FSDthe most advanced driving aid system of Tesla. The FSD is offered as an additional option through a subscription and allows the driver to disregard driving (even in urban environments) as long as it remains attentive to what happens in front of his eyes. For example, the Autopilot demands from the driver the confirmation of lane change but the FSD navigates between the streets by itself, without the need for driver’s validations. In fact, in the United States it allows The car travels 65 meters without a driver Inside. Thus, we can ask a tesla parked to come to pick us up from a distance. And there are people by throwing their cars against a wall. Rober’s experiment has given wings to other YouTuber who have come out to defend the company. In response, Kyle Paul, who has 237,000 subscribers on his YouTube channel and specializes in Tesla videos, He has published his own test. The goal has been the same: will your Tesla Cybertruck before a wall that simulates the continuation of the road? And his answer is that if the car has … Read more

Nvidia has beat its income record again. Paradoxically, Wall Street does not seem to import much

by

The Fever continues to spur Nvidia in the stock market. The company led by Huang has presented again record results for your fourth fiscal quarter. And it has been making the rupture of records into a while. Why is it important. This comes shortly after concerns about Deepseek’s impact and its efficiency in the market that dominates Nvidia. About the idea that less hardware and less power was necessary to continue advancing in AI. Which caused the huge hole in Nvidia bag. The most prominent point of the results was the Awesome Blackwell startthe new chips architecture for Nvidia. Colette Kress, financial director of the company, explained that Blackwell generated 11,000 million dollars in income, exceeding all expectations and becoming “the fastest product launch in the history of our company.” In figures. The data centers business, where technology is concentrated for AI, remains the main growth engine with 35.6 billion revenue in the quarter, 16% more than in the previous quarter and 93% more than in the same period of the previous year For the full fiscal year, this segment reached 115.2 billion, more than double the previous year. The total revenue of the quarter reached 39.3 billion, 12% more than in the previous quarter and 78% higher intelligible. Between the lines. Nvidia is changing her strategy to deal with competition. Jensen Huang emphasized The call with investors that are designing specific platforms for “reasoning AI”, a type of AI that requires up to 100 times more computing capacity than the “traditional” generative AI, which reinforces their most powerful need for hardware even against more efficient models. Reasoning models such as O3 of OpenAi, Deepseek R1 and Grok 3 They require much more intensive processing. Blackwell offers 25 times more yield for these models compared to the previous generation. Infrastructure demand for AI is promoting initial orders of Clusters of 100,000 Gpus or more. And now what? Nvidia has already announced that he will present Blackwell’s successor, called Blackwell Ultra, in the second half of this year, maintaining his annual rhythm. Jensen Huang has confirmed that this transition will be simpler than Hopper’s Blackwellsince it will use the same system architecture. The contrast. Despite the impressive results, Nvidia’s shares barely reacted in the market after the presentationa behavior very different from that seen in previous quarters. The reason: investors perhaps see with caution the reduction in gross margins (from 75% to 73%) and the lowest percentage growth compared to previous quarters, although it remains extraordinary for a company that has established itself as the second most valuable in the world. The big question. Will Nvidia be able to maintain your technological and financial domain against increasingly intense competition and that also threat from China? It seems inevitable that, although Nvidia’s position will remain strong, a certain decrease in demand in favor of new competitors comes. And above all, as the huge investments made by companies in AI do not have a clear and lucrative return, something that seems quite feasible. Maybe it is time to readjust expectations.

This is how Ech works, the Technological Shield of Cloudflare that has put the operators between the sword and the wall

by

The LaLiga fight against illegal soccer broadcasts It has encountered an unexpected obstacle: Ech (Encrypted Client Hello), an encryption protocol that stars in the great conflict and the collateral damage of this battle, which splashes thousands of companies. Turning point. It all started when Cloudflare implemented in October 2023 (Encrypted Client Hello), an extension of TLS that prevents operators from identifying which specific domain is requesting the user. This protocol makes it technically impossible for operators to see which specific domain requests a user. The contrast. ECH works as an additional encryption layer that completely hides the final destination of a connection: When a user tries to access a website, his browser initiates an encrypted “negotiation” (Handshake TLS) With the server. Before ECH, although this connection was encrypted, the name of the domain was traveling “in clear” so that the intermediate servers could enrut the traffic. With ECH, the name of the domain is also encrypted, making it impossible for the operators to know which concrete website the user is accessing. The system is even more complicated because Cloudflare uses shared IPS: The same IP address can house hundreds or thousands of different websites. Without ECH, the operators could see what domain each user requested and block selectively. With ATU activated, they only see an encrypted IP that could be serving both legal and illegal content. This leaves two options to the operators: block all the IP (affecting hundreds or thousands of sites) or not blocking anything. When they choose the first thing the Blocked legitimate websites. To avoid blockages, which also translate into a reputational crisis, some operators are resorting to alternative techniques such as: Traffic patterns analysis. Deep inspection of packages (DPI). BLOCK BY SNI (Indication of the server name) when ECH is not active. But these solutions are complex, expensive and not always effective. The conflict has climbed, Movistar has softened his blockages, Digi has hardened them and Vodafone says to have a more precise solution although it has not revealed details yet (since Xataka We have asked them for this without having received an answer at the time of publishing this article). They possibly use one of the last points. The next. Ech has supposed a huge change in Internet architecture. The precedent of Austria, where IPS blockades were prohibited To protect the neutrality of the network, it suggests that the current regulation model needs to adapt to this new reality. Meanwhile, the pulse between LaLiga and Cloudflare persists, and thousands of Spanish companies also remain trapped in the midst of the conflict.

What does a football club like you in a Nasdaq like this. Cádiz opens on Wall Street

by

Cádiz CF has announced The Nasdaq launch of its Nomadar technological subsidiary, with the aim of capturing 123 million euros to finance Sportech City, its ambitious sports and technological city project. Why is it important. It is the first time that a Spanish soccer club tries to quote in the American technological market. The operation, of complying with what was sought by the club, can transform the Gaditano team, with a current budget of 35 million, to make it a reference for sports innovation and shoot its income. Between bambalins. The nomadar subsidiary is mostly participated by Cádiz and It has the former Liverpool CEO, Peter Mooreas a vowel in your advice. The club will maintain 92% of the vote power even after selling 34.5% of the shares. Deepen. Sportech City will be a multifunctional complex of 110,000 square meters that will include: Auditorium for 40,000 spectators. International category hotel. Convention Center. 56 stores and 17 restaurants. Advanced Sports Medicine Center, Gym and Spa. Nomadar will not only develop the physical complex, but will manage four technological business areas: A sports high performance digital platform. Football academies with advanced analysis technology, International exploitation of the Magic Brand González (Nomadar Ambassador) through Ecommerce. A data center and sports innovation laboratory. The money trail. The required total financing is 370 million euros: 123 million from the IPO. 167 million debt. The rest, direct contributions of the club. Main winner? Cádiz CF can end up multiplying its income and competitive capacity if you achieve success on Wall Street. Its president, Manuel Vizcaíno, He said that this will “increase the salary limit without depending exclusively on television or subscribers.” Yes, but. The project has its risks. FC Barcelona had to resign last year to a similar attempt with its audiovisual subsidiary. The operation will depend on the investment appetite that Clear Street finds, the investment bank in charge of the placement.

Netflix and AI enthusiasm bring Wall Street to the verge of an all-time high

by

NEW YORK — Netflix, Oracle and other big tech companies boosted the New York Stock Exchange on Wednesday, as profits at those companies rose and enthusiasm grew about the revenue prospects that artificial intelligence can generate. The S&P 500 rose 37.13 points, or 0.6%, to 6,086.37, approaching its all-time high set last month. The Dow Jones Industrial Average added 130.92 points, or 0.3%, to 44,156.73, and the Nasdaq Composite rose 252.56, or 1.3%, to 20,009.34. The gains came even as most U.S. stocks fell under the weight of another rise in Treasury yields. For example, smaller company stocks in the Russell 2000 index lost 0.6%, and about two out of every three stocks in the S&P 500 sank. However, the gains from large influential stocks were more than enough to make up for it. Netflix helped lead the rise after it announced that live events such as American football games and a fight between Mike Tyson and Jake Paul helped it add nearly 19 million subscribers during the latest quarter. It also reported higher profits than analysts expected, and indicated that it is increasing subscription prices in the United States and other countries. Netflix titles rose 9.7%. The Netflix logo on a remote control. (Jenny Kane/Associated Press) On the other hand, Travelers advanced 3.2% after also beating analyst expectations for its earnings in the last quarter. The insurer said gains on its investments and growth in net written premiums helped it overcome losses created by Hurricane Milton, which hit the Florida coast in the Gulf of Mexico in October, and other catastrophes. Some of the market’s strongest boosts came from companies related to artificial intelligence. Oracle rose 6.8% after advancing 7.2% the previous day, ahead of the planned announcement — which ultimately came late on Tuesday — about Stargate, a joint venture that the White House says will begin building data centers. and the generation of electricity necessary for the further development of artificial intelligence in Texas. The partnership formed by Oracle, OpenAI and SoftBank will invest up to $500 billion. Shares of SoftBank Group Corp. in Tokyo rose 10.6%. Other AI-related stocks also gained ground, continuing their already fantastic run. Nvidia, the company whose chips are driving much of the movement toward AI, rose 4.4%. Its shares are above $147 after just two years ago they were below $18. The yield on the 10-year Treasury bond rose from 4.57% to 4.60%. It had been largely retreating since an encouraging update on inflation last week, but is still well above its position in September, when it was below 3.65%. In the cryptocurrency market, where prices have risen on hopes that President Donald Trump will make Washington more cryptocurrency-friendly, bitcoin was just above $104,000. On Monday it was above $109,000, a record.
