AI company Anthropic is to lease compute capacity from Akamai.

The seven-year deal, valued at $11.6 billion, will see Anthropic to leverage Akamai Cloud's distributed infrastructure and software to support its CPU workloads.

Akamai said the deal includes potential expansion by up to an additional $9bn, reaching a total potential commitment of approximately $20bn.

Total capital expenditures related to the deal are estimated to be approximately $5.5bn, an increase of approximately $1.7bn in 2026’s capital expenditures to secure and pre-purchase critical supply chain components, including memory.

"Anthropic is advancing the AI revolution and we are thrilled they chose Akamai’s capabilities for building and operating AI infrastructure at scale,” said Dr. Tom Leighton, co-founder and CEO, Akamai. “Akamai has an unparalleled reputation for helping our customers achieve their business-critical goals and build the future. Our 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 has also issued a warrant to Anthropic, the continued vesting of which is tied to expansion of the agreements, for up to approximately five percent of Akamai’s common stock outstanding. A portion of the warrant representing approximately two percent of Akamai’s common stock outstanding is expected to vest in connection with the announced commitment.

The deal adds to the more than $2.8bn in multi-year cloud commitments Akamai has secured this year.
