Matt Garman
CEO at Amazon Web Services
Last year's rank: 43
Matt Garman since June 2024 has led the most profitable division of the world’s largest e-commerce company, and one increasingly dominant in entertainment too.
That scale takes a lot of juice. Which, in turn, has made Garman’s Amazon Web Services (AWS) the nation’s largest owner of data centers, perhaps the fastest-growing commercial real estate asset class.
The scale — or, shall we say, hyperscale — is immense. At the end of 2025, AWS owned 105 data centers in the U.S., according to ABI Research. The nearest competitor was Facebook and Instagram parent Meta with 85. AWS also led the pack in capacity at these centers with 2.3 gigawatts (the only owner to clear 2 GWs).
What’s more, Garman’s team in April 2026 unveiled what it calls “Project Houdini” to speed the construction of more data centers. The project organizes production of the immense campuses around prefabricated modular parts that can be assembled as needed — kind of a Model T assembly line approach to a 21st century phenomenon, with a server room at the center of the end product instead of an internal combustion engine.
All the growth has translated into financial returns for AWS and its parent. AWS’s total income was up 24 percent annually in 2025 to $35.6 billion, and the division recorded its fastest growth in 13 quarters in the last three months of last year.
The web services division in Amazon’s quarterly report also touted new services agreements with a range of companies and other entities in 2025: OpenAI, Visa, the National Basketball Association, Adobe, BlackRock, United Airlines, the U.S. Air Force, AT&T, the London Stock Exchange, DoorDash … you get the picture.
At the nexus of it all is an understandably optimistic Garman, who started at Amazon as an intern 21 years ago, and came aboard AWS shortly after.
“We are incredibly bullish on the company’s growth over the next few years,” Garman told CNBC this past February.
