Tim Cook’s departure: Apple’s new CEO and a $4 trillion milestone
Tim Cook is stepping down as Apple CEO today, remaining executive chair as John Ternus takes the helm on Sept. 1. Over his 15-year tenure, Apple grew from a roughly $350 billion company to a market cap above $4 trillion, powered by iPhone revenue growth, Services expansion, and a shift to Apple Silicon; the company remains focused on AI, with updates to Siri via Gemini and bets on future products like foldable iPhones and smart glasses.
