The Akamai Anthropic deal has Anthropic paying Akamai Technologies about $11.6 billion over seven years for cloud computing capacity. Akamai disclosed it on 24 September 2026 and issued Anthropic a warrant over roughly 5% of its own stock. The capacity is central-processor capacity, not graphics-processor capacity.
What Anthropic Committed To
The commitment sits inside an existing contract rather than a new one. Akamai’s filing describes Project Plan 2 and Project Plan 3, entered on 18 September 2026 under a Master Services Agreement dated 5 May 2026, each carrying an initial seven-year term that begins on its own service start date.
| Item | Figure |
|---|---|
| Committed contract value | About $11.6 billion |
| Initial term | Seven years per Project Plan |
| Possible expansion | Up to an additional $9 billion |
| Total potential commitment | About $20 billion |
| Earlier 2026 commitments from Anthropic | More than $2.8 billion |
| Akamai capital spending tied to the $11.6 billion | About $5.5 billion |
Akamai said “Anthropic has committed to pay the Company approximately $11.6 billion in the aggregate under the Project Plans”, according to its 8-K filing with the Securities and Exchange Commission, the report United States companies must file on material events.
How the Warrant Actually Works
The headline figure of 5% is the end point of a structure most coverage compressed. Akamai issued a warrant — a right to buy shares at a fixed price — over 387,051 shares of Series B Non-Voting Convertible Preferred Stock, at an exercise price of $2,226.60 per preferred share.
Each preferred share converts into 20 shares of common stock. That makes the warrant worth up to 7,741,020 common shares on an as-converted basis, or about 5% of Akamai’s outstanding common stock, at an effective $111.33 per common share.
It does not all vest at once. The warrant vests in four tranches: the first, around 40% of the total, on the announced commitment, and the three remaining tranches of roughly 20% each on every further $3 billion of contractual value Anthropic commits. Three tranches of $3 billion is the $9 billion expansion path, which is why the full 5% and the full $20 billion arrive together or not at all.
The stock is non-voting, so the stake carries no board or shareholder control even if exercised in full.
Why the Capacity Is CPU and Not GPU
Akamai says the commitment supports Anthropic’s “accelerating CPU workload demands”. A central processing unit is a general-purpose chip; a graphics processing unit is the accelerator used for training large models and for the heaviest inference work.
The distinction decides what Akamai has to build. CPU capacity draws less power per unit of compute than GPU capacity, and it serves the surrounding work an AI service generates — request handling, orchestration, retrieval, tool calls and the ordinary web infrastructure around a model — rather than the model training itself. Akamai’s chief financial officer, Ed McGowan, put it plainly: “There’s an awful lot of CPU that’s needed to run all this. It’s not all just GPU.”
What Akamai Has to Build, and What It Is Buying
Akamai estimates total capital expenditure related to the $11.6 billion commitment at about $5.5 billion, and says it anticipates “no impact to the company’s 2026 revenue guidance, and an increase of approximately $1.7 billion in capital expenditures in 2026”, according to the announcement filed as an exhibit to the 8-K.
Two supply deals landed alongside it. Akamai entered a hardware supply agreement with Lenovo on 23 September 2026, and on 24 September authorised Jabil, its contract manufacturer, to buy roughly $1.7 billion of memory components — the pre-purchase the 2026 capital spending increase is meant to cover.
On power, Akamai estimates its signed Cloud Infrastructure Services commitments will need about 95 to 105 megawatts. Securing that much power on schedule is the practical constraint on AI buildouts, as Oracle’s force majeure notice over a delayed data centre demonstrated this week.
When the Money Comes Back
The revenue lags the spending by years. Reporting by Information Security Media Group on 25 September 2026, drawing on Akamai’s guidance, put revenue from the commitment as starting in the second half of 2027, contributing $150 million to $300 million across 2027, fully ramped by the end of 2028, and running at roughly $1.7 billion a year thereafter.
That annual run rate is a different $1.7 billion from the 2026 capital spending increase, and the two are easy to conflate. One is money going out next year; the other is money coming in from 2029 onwards. Akamai has not restated its 2026 revenue guidance.
The commitment also runs against the direction of model pricing. Anthropic cut prices on parts of its developer interface earlier in the month, alongside reductions at OpenAI of up to 50%, which means the compute bill is rising while the revenue per unit of output is falling.
The Termination Clause Most Coverage Skipped
The filing gives Anthropic two exits. It may terminate a Project Plan on a material uncured breach by Akamai, and it may terminate on a change of control of Akamai in favour of a direct competitor.
The second is unusual and points at the structure’s logic: Anthropic is committing a sum comparable to Akamai’s market value and taking equity alongside it, so it has written in protection against waking up as a customer of a rival.
How the Market Took It
Akamai shares rose sharply and then gave much of it back. On 25 September 2026, intraday gains were reported at between about 14% and 16%, with one reading putting the peak at $128.46, before the advance narrowed to roughly 5% to 8% during the session. One close was reported at $115.84, up 4.92%.
Share prices move continuously, so those are readings on a single day rather than a settled valuation of the contract. Akamai also said the $11.6 billion commitment is the largest in the company’s history, which began in 1998.
Akamai Anthropic Deal: Frequently Asked Questions
How Much Is the Akamai Anthropic Deal Worth?
About $11.6 billion committed over seven years, disclosed on 24 September 2026, with a path to roughly $20 billion if Anthropic commits a further $9 billion.
What Does Akamai Provide Under the Agreement?
Dedicated cloud computing capacity and related managed support services, aimed at Anthropic’s central-processor workloads rather than graphics-processor training capacity.
Does Anthropic Now Own Part of Akamai?
Not yet. Anthropic holds a warrant, a right to buy shares later. It covers up to 7,741,020 common shares on an as-converted basis, about 5% of Akamai’s outstanding common stock, and vests in four tranches tied to how much Anthropic commits. The shares are non-voting.
When Will the Contract Show Up in Akamai’s Revenue?
Revenue is reported to begin in the second half of 2027, with $150 million to $300 million across 2027 and a full ramp by the end of 2028. Akamai says its 2026 revenue guidance is unchanged.
Can Anthropic Walk Away?
The filing allows Anthropic to terminate on a material uncured breach by Akamai, or on a change of control of Akamai in favour of a direct competitor.
What Is Akamai Spending to Serve the Contract?
About $5.5 billion of capital expenditure in total, including an increase of roughly $1.7 billion in 2026 to pre-purchase components such as memory. Akamai puts the power requirement across its signed cloud commitments at about 95 to 105 megawatts.
