Anthropic Just Signed Akamai’s Biggest Contract Ever, for CPUs

AI infrastructure news usually means GPUs, hyperscalers, and circular equity. This week’s largest Akamai contract in company history is mostly about the unfashionable chip: the CPU.

So basically: on Sept. 24-25, 2026, Akamai said Anthropic committed about $11.6 billion over seven years for dedicated cloud capacity (more than six times a $1.8 billion arrangement Bloomberg had flagged in May) with a warrant structure that could push total spend toward $20 billion.

The deal on the page

TechCrunch, citing Akamai’s announcement and securities filing, is clear on the soft spots. The commitment depends on Akamai meeting delivery and availability terms. Either side can exit under certain conditions. This is a huge contracted demand signal, not a prepaid lockbox.

Revenue timing is deliberately slow. Akamai expects nothing from the deal in 2026. Investor-call guidance pointed to $150-300 million in 2027, starting in the second half, then an annualized run rate near $1.7 billion by the end of 2028. To stand that capacity up, Akamai plans roughly $5.5 billion in related capital spending, including about $1.7 billion added to 2026 capex for components such as memory ahead of the build.

Shares jumped as much as 17% after hours on the news, per Wall Street Journal coverage cited by TechCrunch.

Why CPUs, and why the warrant flips the script

Akamai highlighted CPU demand tied to AI agents doing more ordinary computer work (running code, browsing, orchestration) even though it did not spell out Anthropic’s exact workload mix. That is the quiet implication: frontier labs are not only buying H100-class iron. Agent stacks need a lot of boring, general-purpose compute next to the accelerators.

The financing structure is the other headline. Akamai issued Anthropic a warrant on nonvoting preferred convertible into about 7.7 million common shares (up to roughly 5% of outstanding stock) at $111.33 a share. About 2% is expected to vest on Anthropic’s first payment. Each additional $3 billion of cloud commit unlocks about another 1%, which is how the ceiling reaches ~$20 billion. It is the first warrant Akamai has attached to a cloud deal.

That reverses the usual circular pattern where chip or cloud suppliers invest into the lab. Here the supplier hands the customer upside that grows with spend, closer to the AMD-OpenAI warrant style than to a classic cloud prepay.

Progress and limits

Progress: Anthropic is diversifying compute beyond the usual hyperscaler logos, Akamai gets a landmark backlog, and the market got a clean reminder that agent-era demand is not GPU-only. Limits: no 2026 revenue, multi-year build risk, termination clauses, and a structure that still concentrates counterparty risk if Anthropic’s growth or Akamai’s delivery slips. A warrant is not the same as cash equity from Amazon, Google, or Microsoft, relationships Anthropic already has on the investor side.

Watch first payment timing, whether the optional $9 billion expansion actually triggers, and how much of Anthropic’s inference and agent traffic still sits on traditional GPU clouds. The wow fact is the dollar figure. The operating fact is that the money does not start printing for Akamai until deep into 2027.
