What Anthropic is buying
The deal supports Anthropic’s growing need for CPU computing on Akamai Cloud, which runs from thousands of locations around the world. CPUs are the general-purpose processors found in most computers. GPUs are the chips most often used to train AI models.
Akamai says the commitment can grow by up to $9 billion more, for a total of about $20 billion.
Akamai expects to spend about $5.5 billion on equipment for this deal. It is also raising its spending this year by about $1.7 billion to buy parts such as memory in advance.
Figures come from Akamai’s announcement. Anthropic was not quoted in it.
A stake that grows with spending
Akamai gave Anthropic a warrant, a right to buy shares later, for up to about 5% of the company at $111.33 per share.
About 2% vests with the new commitment. Each extra $3 billion of spending unlocks about 1% more.
Chief executive Tom Leighton told Bloomberg that this is the first time Akamai has agreed to a warrant in a cloud deal. “It’s a serious step, but I think in this case it made sense to do,” he said, according to The Next Web.
“Anthropic is advancing the AI revolution,” Leighton said in Akamai’s announcement.
Investors cheered, with caveats
Akamai’s shares jumped in late trading on Thursday. Reports gave different figures for the size of the jump.
Akamai says the deal will not change its 2026 revenue forecast. The Next Web reports that the contract builds on a $1.8 billion deal the two companies signed in May.
According to The Next Web, Bloomberg noted investor concern about circular AI deals, in which companies that buy from each other also invest in each other. Critics say such deals make real demand for AI harder to measure.
Akamai’s announcement did not include a comment from Anthropic.
