Anthropic's $11.6 billion Akamai contract pays out only as Akamai delivers CPU capacity

In my view the delivery terms favour the buyer. Anthropic pays as capacity arrives and meets the availability requirements in Akamai's filing ^[9], so the schedule risk sits with Akamai. Spread evenly, $11.6 billion over seven years is about $1.66 billion a year ^[18]. The money will not arrive evenly. Akamai's investor presentation projects full run-rate revenue from the agreement only by the end of 2028 ^[11], and Akamai says its capital spending comes before that run rate ^[2].

The build is large next to the contract. Akamai estimates about $5.5 billion in capital expenditure tied to the initial commitment ^[2]. That is roughly 47 cents of spending for every contracted dollar ^[19]. Akamai also plans about $1.7 billion of 2026 spending to secure components, memory among them ^[3]. The sources disagree on how those two figures relate. The Decoder describes the $1.7 billion as extra spending on top of the $5.5 billion ^[4], while The Stack gives $5.5 billion as the spend needed to meet the contract ^[5]. If The Decoder is right, Akamai's outlay is about $7.2 billion, or 62 percent of the contract value ^[20].

The warrant figures reconcile. At about 1 percent per additional $3 billion ^[7], the full $9 billion expansion vests 3 percent. Add the 2 percent on the initial commitment and the total reaches the 5 percent cap ^[14]. The Decoder's split, citing Reuters, matches ^[8].

The deal covers Anthropic's CPU workloads ^[1]. Anthropic has not detailed how it will divide work among Akamai, Amazon Web Services, Google Cloud and Microsoft ^[12]. The contract is also small next to Anthropic's other buying. The Decoder reports $517 billion in compute deals over eleven months, including a $45 billion Nscale commitment the month before ^[13]. This contract is about 2.2 percent of that total ^[21] and about a quarter of the Nscale deal ^[23]. These sources document one buyer reserving CPU capacity seven years out. Whether other AI companies are doing the same is outside what they report.

For Akamai, the contract is more than four times the size of all its previous 2026 cloud deals combined ^[15]. Those earlier deals therefore total less than about $2.9 billion ^[22]. Chief executive Tom Leighton told The Stack the deal is "a great proof point and validation, which is helpful for us obviously, it helps accelerate revenue, and we'll be building out the platform even more." ^[16] Investors did not wait for 2028. Akamai's stock rose 22 percent after hours, The Decoder reported ^[24].

If Akamai's build slips, the delivery-gated payments limit what Anthropic owes on this contract ^[9]. Anthropic's wider exposure is the sum of everything it has signed. According to The Decoder, Amodei warned in December 2025 that Anthropic could go bankrupt if its estimates were off by even a small margin ^[17].
