Capacity at the world's largest cloud provider is mostly sold out, Amazon CEO Andy Jassy claimed.

Speaking on the a16z podcast, Jassy said that Amazon Web Services (AWS) is nearly fully booked for next year.

"Even spending $220 billion this year, we're leaving a meaningful amount of demand on the table," he said.

"Obviously, at this point '26 is sold out. We always leave a certain amount for On Demand, and our inference service Bedrock or EC2, but '27 is largely sold out. A good chunk of '28 is sold out."

He claimed that the company was "probably putting more capacity [live] than anybody else because we're very passionate about continuing to be the significant leader in the infrastructure and AI space, like we've been.

"We're spending $220bn this year, and we could spend a lot more, and it wouldn't be a bad use of capital in both medium- to long-term, and I think we still probably wouldn't satisfy all the demand. There is just an incredible demand right now."

Jassy said that both AI and non-AI cloud demand was growing rapidly, but the company had to make "real tradeoffs" over which vertical to focus on.

Impacting its ability to scale rapidly are a number of supply issues, including memory. "I wish I could tell you that I thought that the supply constraints would be just a 2027 issue," Jassy said. "I think we'll see them in different components for several years."
