A quiet shift is reshaping the C-suite. From Silicon Valley to Zurich, top executives are stepping down from their posts, not because their companies are failing, but because the adoption of AI is demanding a new kind of leadership.
Executives who thrived in the digital era are making way for leaders who can navigate the next stage of the AI scale-up. For customers, these moves are more than just behind-the-scenes boardroom drama. They’re changing the way consumers and businesses shop, interact with technology and experience services every day.
An Unprecedented Wave of CEO Departures
CEO turnover in 2024 and 2025 has been at an all-time high. Between January and August 2025, 1,504 CEOs left their posts, according to global outplacement and business and executive coaching firm Challenger, Gray & Christmas. That was the highest number recorded since it began tracking the data in 2002 and up 4 percent from the first eight months of 2024.
Interestingly, the average age of departing CEOs in September 2025 was just 52, the youngest in years. Many of these leaders were originally brought in to lead digital transformations, but as AI becomes the next frontier, boards are bringing in executives with fresh expertise to tackle new challenges.
What stands out is that this turnover is no longer confined to struggling firms. Among S&P 500 companies, succession rates at top-quartile performers have jumped from 7 percent last year to 12 percent in 2025, nearly matching the 14 percent turnover rate of companies performing in the bottom quartile.
In the past, CEO changes tended to happen at struggling firms, as boards stepped in to replace leadership in an attempt to turn around poor performance. But now, forward-looking boards are increasingly using leadership transitions as a strategic tool, intentionally placing executives who are well-equipped to guide companies into the AI era.
That was the case with Five9’s announcement this week that Amit Mathradas will succeed Mike Burkland as its CEO from February next year. With Burkland retiring because of ongoing health issues, the company took the opportunity to look for a successor with a track record of AI innovation.
Burkland highlighted the importance of Mathradas’ AI experience in leading the company:
“His deep expertise in product innovation, AI, and operational excellence at scale makes him ideally suited to lead the Company into its next chapter. As we advance our AI-driven CX strategy, we believe Amit will help lead Five9 to even greater success.”
Why Walmart’s CEO Is Passing the Baton in the AI Era
A clear example of the generational shift underway is Walmart’s upcoming CEO handover. Doug McMillon, 59, who has led the retail giant since 2014, has also announced he will retire in February 2026, passing the baton to John Furner, 51, who is currently President and CEO of the company’s U.S. division. McMillon candidly told CNBC in an interview last week that the AI transition is the reason for his decision to step aside:
“With what's happening with AI, I could start this next big set of transformations, but I couldn't finish.”
“About a year ago, I really started feeling like this next run, you could see what agentic commerce was going to look like, the vision for AI shopping. And I started thinking about everything that needs to happen over the next few years. And it really caused me to think that now was the right time [to leave],” McMillion added.
Under McMillon, Walmart transitioned from a traditional retailer to a tech-led enterprise with an advanced digital foundation. The company’s next chapter will center on agentic AI, delivering automated, highly personalized, and contextually aware shopping experiences, McMillion said.
“It's really exciting to think about what can happen. Think about all the things that people love about shopping. We have the opportunity to increase those and invent new ways to shop, and we have the opportunity to reduce some of the friction like we've never done before, to take out the things that people don't enjoy doing.”
McMillon outlined Walmart’s vision for its AI-driven Sparky platform next year, a new customer front end designed to adapt its interface depending on the user’s intent—whether browsing for fun, searching efficiently for a specific item, or planning an event.
“Then think about all the stuff that's going to happen with better inventory management, all these investments we've been making in physical automation paired with data and increasingly intelligent software power change the whole system,” McMillon added.
Furner, who has been at Walmart for more than 30 years, brings deep organizational knowledge and experience with technology-driven operations. That is the type of leadership that boards are now seeking—executives who can navigate AI at scale while implementing transformational initiatives across complex enterprises.
“When you see somebody who's ready to run the next lap better and faster than you are, it's time to hand the baton and get out of the way and just cheerlead,” McMillon said.
The AI Imperative Exerts Organizational Pressure
Research released earlier this month by SHRM underscores how AI adoption has become a primary strategic concern. Forty percent of CEOs are focused on AI adoption in 2026 and 56 percent view technological advancement as the most pressing macroeconomic challenge, surpassing traditional concerns like inflation, economic uncertainty, or market competition.
Optimism about AI’s potential is tempered by caution. Many leaders lack confidence in their executive teams’ ability to execute AI strategies. Surveys reveal that while boards and investors may be enthusiastic, the C-suite itself is often underprepared. For instance, Gartner has found that while 77 percent of CEOs believe AI is ushering in a new business era, less than half feel their executive teams have the know-how and skills they need to rollout AI effectively.
“The speed of change inside and outside our organizations is accelerating. As CEOs, our challenge isn’t just to keep up, but to set the pace,” said Johnny C. Taylor, Jr., SHRM President and CEO.
For CEOs who built their careers before AI was part of the picture, the gap between what the business now needs and what their teams can actually deliver has become too hard to ignore, pushing some to step aside.
