The business fabric in the US is experiencing one of its most turbulent periods. Not only because of the coming to power of Donald Trump and his upstart tariff policiesbut because of the challenge in management and governance models that poses to AI.
OK to what was published by The Wall Street Journalthe US is experiencing a generational change at the head of the main listed companies. In 2025 alone, one in nine CEOs at the 1,500 largest companies in the S&P 1500 will be replaced, the highest rate since records began in 2010. The demands of AI they are retiring the CEOs more experienced.
Relay record at the top. According to data revealed by a study from the consulting firm Spencer Stuart, 168 people debuted as CEO in large listed companies. In more than 80% of these appointments, the new managers lacked previous experience leading companies of that category, although 60% of those appointments were promotions. Furthermore, two-thirds of these incorporations had also not served on boards of directors before. That is to say, its greatest value It was not his experience, but his youth.
The trend continues strongly during the first two months of 2026. Top-tier companies such as Walmart, Procter & Gamble, Lululemon, Disney, PayPal and HP have made changes in his highest executive position. This pace marks a great experiment in leadership by large companies in the face of unstable markets, where the pressure to obtain immediate results accelerates the departures of veterans.
Younger and younger leaders. The average age of new CEOs dropped to 54 years in 2025, which is almost two years less than the record in 2024, thus confirming that this is a trend that has been occurring for some years. Although only 3% of managers in large companies are under 40 years old, 64% are between 50 and 59 years old, and only 12% are over 60 years old.
Some examples are found in recent replacements like disneyin which Josh D’Amaro, 55, took the replacement of Bob Iger 75 years old. This replacement reflects a commitment to fresh talent, but with a deep knowledge of the companies they are going to lead, but without experience in decision-making.
The life cycle of a CEO. Spencer Stuart analysts found that CEOs of large companies have “a useful lifespan” at the helm. During the first year in office, the new CEO begins the “honeymoon effect” and his companies outperform the S&P 500 by 10% on average. However, in the second year of office, 73% experience a drop in returns of an average of 21%.
Between the third and fifth years at the helm, a reinvention of leadership occurs, which precedes a stagnation between the sixth and ninth years. Beginning in the tenth year, stable leadership is established. The majority cannot taste that stability since, after the third year, 25% have already left the position. 50% do not reach the sixth year as CEO.
The average duration of active CEOs is 7.1 years, and 86% of departures are voluntary and agreed upon with the board of directors. Only 9% of CEO changes in the S&P 500 group of companies have been forced removals. It should be noted that only 16% of new appointments to senior management positions they have been womenwhich represents a bittersweet historical record.
