What happened
- At 4:01 p.m. New York time on September 24, Akamai announced a commitment from Anthropic of $11.6 billion over seven years to use its distributed cloud for CPU workloads, the general-purpose processors.
- According to the 8-K filed with the SEC, the plans were signed on September 18 under a master agreement dated May 5, and payment is subject to Akamai meeting delivery and availability requirements. The deal can be expanded by up to $9 billion, for a potential total of close to $20 billion.
- Akamai issued Anthropic a warrant (the right to buy shares at a fixed price) for up to about 5% of its equity, at $111.33 per share. About 2% vests with the initial commitment; each additional $3 billion in services adds about 1%.
- Akamai estimates $5.5 billion in capital expenditure tied to the contract and is raising its 2026 investment by about $1.7 billion, partly to buy memory components in advance.
Why it matters
- The buyer ends up as a shareholder in the seller. Akamai pays with its own equity to lock in the contract, and Anthropic accumulates a bigger stake the more it spends. In addition, the 8-K allows Anthropic to terminate the contract if a direct competitor takes control of Akamai: the customer also gets a say in who can own its supplier.
- That the contract is for CPUs rather than graphics cards is a signal about demand. An agent spends much of its work running tools, browsing and executing code, tasks that fall on general-purpose processors.
- If a vendor front-loads memory purchases within a $1.7 billion investment increase, that component becomes less available to everyone else. For companies in Chile renewing servers or contracting cloud, the pressure arrives through hardware prices, not through the headline.
The number
$20 billion. The contract’s ceiling if Anthropic exercises the full planned expansion.
Context
Anthropic has just cut the cost of Opus 5.5 by 40%. It is selling cheaper while signing compute commitments of this size, a bet that volume will make up for margin.
What’s next
- The warrant has a seven-year term to complete the expansion.
- Akamai does not expect the contract to affect its 2026 revenue guidance.
- No timeline announced for the first expansion.
Bottom line
Big Tech companies already book paper gains on their stakes in AI companies. Akamai reverses the direction: it gives a stake of its own to the company buying from it.
