Big Sneakers To Fill: Tim Cook’s Apple Legacy Is About More Than The Numbers

For 15 years, Tim Cook had one of the toughest jobs in corporate America: follow Steve Jobs. That alone would have been enough to make most CEOs lose sleep, grow a few gray hairs—or quietly update their résumé. Cook did something considerably more difficult. He made Apple even bigger.

As Cook handed the CEO keys to John Ternus on September 1, 2026, he left behind a company valued at roughly $4.6 trillion, compared with about $350 billion when he took over in 2011. Apple’s stock gained more than 2,000% during his tenure.

And then there is the number that makes the whole thing sound almost absurd: About $32 million an hour. That is Bank of America analyst Wamsi Mohan’s estimate of how much Apple’s market capitalization increased, on average, during Cook’s nearly 15 years as CEO.

Apparently, when Cook took the job, “growth opportunity” wasn’t just corporate-speak. It was a very large understatement.

He Didn’t Try to Be Steve Jobs

Perhaps Cook’s greatest accomplishment was understanding something many successors never do: He wasn’t Steve Jobs. And he didn’t try to become him.

Jobs was Apple’s showman-in-chief—the black turtleneck, the dramatic pauses, the “one more thing,” and the uncanny ability to convince millions of people that they absolutely needed something they had never previously heard of.

Cook was different. He was the operations guy. The supply-chain guy. The spreadsheet guy. The guy who could probably look at a container ship and tell you exactly why it was 17 minutes late.

And that turned out to be precisely what Apple needed.

Cook inherited Jobs’ product ecosystem and turned Apple into an extraordinarily efficient global machine. Revenue grew from roughly $108 billion in 2011 to $416 billion in fiscal 2025. Apple’s active installed base has grown to more than 2.5 billion devices.

In other words, Cook didn’t just keep the Apple train on the tracks. He added more tracks.

The iPhone Was Only the Beginning

The easiest way to judge Cook’s Apple would be to look at the iPhone. That would also miss much of the story. Under Cook, Apple launched the Apple Watch, AirPods and Vision Pro, while moving the Mac from Intel processors to Apple’s own silicon—a transition that became one of the company’s most important technical achievements.

But perhaps Cook’s most consequential move was less glamorous. He turned Apple into a services company. In 2011, Apple’s services business generated about $9.4 billion for the year. By the third quarter of 2026, services revenue had reached $30.7 billion in a single quarter. Fiscal 2025 services revenue was approximately $109 billion, with Apple reporting about 1.5 billion subscriptions. There was:

Apple Pay.
iCloud.
Apple Music.
Apple TV+.
Apple Arcade.
Apple News+.
App Store advertising.

The genius of the model is that once you buy the shiny rectangle, Apple would very much like to remain part of your financial life indefinitely. You don’t just buy an iPhone. You subscribe to the neighborhood.

The Supply Chain Became a Competitive Weapon

Cook’s background in operations may not have generated the applause that greeted an iPhone launch, but it arguably became one of Apple’s greatest competitive advantages. He inherited a company whose success depended heavily on manufacturing in Asia and turned supply-chain management into something approaching corporate warfare.

That strategy helped Apple scale products to extraordinary volumes while maintaining its famously tight control over manufacturing and distribution. It also created one of Cook’s biggest vulnerabilities. China.

Apple remains deeply dependent on Chinese manufacturing and the Chinese market, leaving the company exposed to geopolitical tensions, trade disputes and political pressure. Cook spent years navigating an increasingly complicated relationship between Washington and Beijing.

That balancing act occasionally put Apple in uncomfortable territory. Critics have questioned Apple’s decisions involving censorship, Chinese regulations, labor practices and data storage. So, while Cook deserves enormous credit for globalizing Apple, the same globalization created problems his successor will have to manage.

And Then There Is AI

If Cook has a glaring blemish on an otherwise extraordinary résumé, it may be artificial intelligence. Apple didn’t exactly miss the AI revolution. But it hasn’t led it, either.

While companies such as Google, Microsoft and OpenAI raced ahead with generative AI, Apple appeared more cautious. Apple Intelligence arrived, but Apple’s AI strategy has faced criticism for moving too slowly and relying increasingly on outside technology partners. That leaves Ternus with perhaps the biggest question of the post-Cook era:

Can Apple produce the next great computing platform—or will it spend the next decade trying to catch up to everyone else? That’s a considerably more intimidating question than figuring out which color the next iPhone should be.

Cook’s Other Legacy: Returning Money

Cook also became one of corporate America’s great capital-return machines. Apple restored its dividend in 2012 and embarked on an enormous share-repurchase program. Over Cook’s tenure, the company returned more than $1 trillion to shareholders.

Wall Street tends to like that sort of thing which helps explain why Cook’s tenure has been so spectacular for investors even when critics complained that Apple wasn’t producing another iPhone-level revolution every 18 months. There is a difference between inventing the future and making an enormous amount of money from the present. Cook was exceptionally good at the latter. And occasionally pretty good at the former.

The Jobs Question Will Never Go Away

History will probably continue comparing Cook with Jobs. It’s unavoidable. Jobs built the mythology. Cook built the machine. Jobs made Apple feel like a rebellious technology company changing the world. Cook made it into one of the most powerful and profitable corporations in human history. Neither accomplishment is small.

And perhaps the fairest assessment is that Cook understood something important about succession: Apple didn’t need another Steve Jobs. It needed Tim Cook.

So, About Those Sneakers…

John Ternus now inherits Apple at approximately the same moment someone might inherit a $4.6 trillion house with 2.5 billion things plugged into it, several governments arguing over the thermostat and Wall Street standing outside demanding that the plumbing produce 15% annual growth.

No pressure. Ternus has been at Apple since 2001 and played major roles in hardware development, including Apple silicon and products such as the Mac, iPad, iPhone, AirPods and Apple Watch. He isn’t walking into the job as an outsider.

But familiarity isn’t the same thing as easy. Cook leaves behind a company that is extraordinarily profitable, extraordinarily valuable and extraordinarily difficult to improve. That’s the strange paradox of succession. The bigger the legacy, the smaller the margin for error.

Tim Cook’s sneakers aren’t merely big. They’re enormous. According to one analyst’s calculation, Apple added roughly $32 million to its market capitalization every hour Cook was CEO.

That’s about $533,000 a minute. Or roughly $8,900 every second. So, John Ternus, enjoy your first day. Take a deep breath. Maybe order some coffee. And whatever you do, don’t lose the other sneaker. Because these are going to be very big sneakers to fill.
