Corporate America is experiencing unprecedented leadership turnover. Last year, roughly one in nine CEOs at the largest publicly traded companies was replaced, marking the highest churn rate since the post-financial-crisis period. This wave continued into 2026, with major firms like Walmart, Procter & Gamble, Disney, PayPal, and HP announcing new leadership. Boards are responding to a fundamentally altered business environment shaped by artificial intelligence, fragmenting global trade, and geopolitical tensions. The incoming CEOs are notably younger, averaging 54 years old, with over 80% serving as first-time public-company chiefs. Many lack traditional corporate board experience. While some transitions were planned, like Warren Buffett's succession at Berkshire Hathaway, others proved abrupt.
