Apple’s growth under CEO Tim Cook: The journey from $350 billion to $5 trillion

Apple touched the $5 trillion market capitalisation mark on July 28, 2026, marking a historic milestone for CEO Tim Cook, just weeks before he hands over the reins on September 1. With the milestone, Apple also reclaimed its position as the world's most valuable company, ahead of Nvidia.

The number showcases Cook’s dedicated 15-year run at Apple. When he took charge from Steve Jobs on August 24, 2011, Apple was valued at $348 billion. Under his leadership, the company delivered a 2,180% return in share price, effectively adding around $32 million in shareholder value every hour of his tenure.

Apple’s market capitalisation journey under Tim Cook

Apple hit the 1 trillion mark in August 2018, and it took 38 years post-IPO to achieve this success. In just two years, the company was valued at $2 trillion in 2020 on pandemic-driven demand, and by January 2022 it had crossed $3 trillion on the back of its services business.

The fourth trillion came in October 2025, driven by strong iPhone sales and institutional investment. The $5-trillion milestone was reached in less than a year, in July, 2026. Under Cook’s tenure, his biggest bet was Apple's ecosystem with services such as iCloud and Apple Pay, rather than solely relying on iPhone sales.
 
He also leaned towards aggressive share buybacks that cut outstanding stock by roughly 44%, and a comparatively capital-light approach to AI by leasing infrastructure rather than building it from scratch.

However, Apple is again facing challenges amid the AI book. The company's market cap has fallen from around $5 trillion to about $4.5 trillion. This happened after investors sold Apple shares following its earnings results. Three major concerns are highlighted:

• Higher hardware costs because of the global memory shortage.
• Doubts about Apple’s AI strategy, particularly whether its delayed AI features and revamped Siri can actually generate meaningful revenue
• Regulatory challenges, especially in markets such as China.

Now, John Ternus will inherit Apple at an interesting point as Apple is under pressure to prove that its AI strategy can deliver meaningful benefits to consumers.
