Akamai and Anthropic Sign $11.6 Billion AI Cloud Infrastructure Deal

Akamai Technologies announced on 25 September 2026 that it has entered into a significantly expanded relationship with Anthropic, the AI safety company, valued at $11.6 billion in contractual commitments over a seven-year term. The agreement is designed to support Anthropic's accelerating CPU workload demands by leveraging Akamai Cloud's distributed AI infrastructure and software.

The deal represents the largest single commitment disclosed as part of Akamai's Cloud Infrastructure Services (CIS) business. The company said the new agreement adds to more than $2.8 billion in multi-year CIS commitments across its customer base that had already been announced earlier in 2026.

As part of the arrangement, Akamai has issued a warrant to Anthropic allowing it to purchase non-voting convertible Series B Preferred Stock. The warrant covers 7.7 million shares of Akamai common stock on an as-converted basis, representing up to approximately 5% of Akamai's common stock outstanding, at an exercise price of $111.33 per share. A portion of the warrant representing approximately 2% of Akamai's common stock outstanding is expected to vest in connection with the initial $11.6 billion commitment, with the remaining approximately 3% vesting upon expansion of the commitment by up to an additional $9 billion within the seven-year term. Each additional $3 billion purchase of cloud services, at mutually agreed upon terms, would result in the vesting of approximately 1% of Akamai's common stock outstanding.

Akamai chief executive Dr. Tom Leighton framed the agreement as evidence of the company's positioning in the AI infrastructure market. "Anthropic is advancing the AI revolution and we are thrilled they chose Akamai's capabilities for building and operating AI infrastructure at scale," Leighton said. He added that Akamai's "expanding global footprint, combined with our years of experience serving the world's largest enterprises, positions us to be the infrastructure provider for secure and responsible AI applications and workloads."

Akamai stated that its cloud platform supports a continuum of compute from core to edge across a distributed network spanning thousands of points of presence, with diversified hardware enabling customers to build, run and optimise applications and their delivery to users and agents.

On the financial implications, Akamai said total capital expenditures related to the $11.6 billion commitment are estimated at approximately $5.5 billion. The company anticipates no impact to its 2026 revenue guidance, but expects an increase of approximately $1.7 billion in capital expenditures in 2026 to secure and pre-purchase critical supply chain components, including memory.
