Cook's Apple Legacy: A $4 Trillion Giant With Growing AI Challenges

When Tim Cook took over as CEO of Apple in August 2011, he faced high expectations and doubts about his ability to sustain the company's growth. Fifteen years later, the numbers tell a compelling story of success.

Cook led Apple from a $350 billion market capitalization to around $4 trillion, with its stock price increasing nearly 25-fold. The company's annual revenue has grown dramatically, rising from about $108 billion in 2011 to more than $400 billion.

One of Cook's biggest achievements was transforming Apple into a business that extends beyond hardware. Its services segment, including the App Store, Apple Music and Apple Pay, generates over $100 billion annually and carries broader margins than its hardware business.

Cook also oversaw a major shift in Apple's chip strategy, moving away from Intel and designing its own processors for Mac computers under the Apple Silicon platform. The transition gave Apple greater control over performance and product development.
