Anthropic signs $11.6 billion cloud deal with Akamai over seven years

The $11.6 billion, seven-year agreement, announced on September 24, 2026, can be expanded to roughly $20 billion. But the most striking feature is not the sum: Anthropic receives a warrant for up to 5 percent of Akamai's shares, which vests only as the company actually spends money.

Akamai Technologies announced on September 24, 2026 a substantially expanded agreement with Anthropic worth $11.6 billion over seven years. The commitment is intended to cover Anthropic's rapidly growing CPU workloads through Akamai Cloud's distributed AI infrastructure and software, the company writes in a press release [cc753d26]. The stock rose sharply in extended trading — but how sharply is unresolved: Reuters reports 15 percent, while Seeking Alpha reports more than 26 percent [ee044036, 4919f846].

The numbers in the deal

The agreement includes an expansion option of up to an additional $9 billion, which would bring the total potential commitment to roughly $20 billion [cc753d26, ee044036]. According to Akamai's own estimates, total capital expenditures of around $5.5 billion are tied to the agreement, of which about $1.7 billion comes in 2026 to secure and pre-purchase critical supply chain components, including memory. The company expects no change to its 2026 revenue guidance as a result of the agreement [cc753d26].

The deal's detailed contractual basis is laid out in an SEC Form 8-K: the commitment is formalized through "Project Plan 2" and "Project Plan 3," entered into on September 18, 2026 under a Master Services Agreement dated May 5, 2026 [ad9fd1f1]. CryptoBriefing reports that the agreement expands a previous $1.8 billion Anthropic–Akamai contract announced in May [f24fbd61]. The press release also notes that this comes in addition to more than $2.8 billion in multi-year Cloud Infrastructure Services commitments across Akamai's customer base — a separate and broader figure than the earlier Anthropic contract [cc753d26]. One coverage outlet, CryptoBriefing citing Financial Juice, described the deal as "$12 billion," but the press release, Reuters and the other sources agree on $11.6 billion, which must be considered the correct figure [55f3228c, cc753d26].

The warrant that makes the deal unusual

What distinguishes this contract from other major cloud deals is the equity component. Akamai has issued Anthropic a warrant for up to roughly 5 percent of the company's outstanding share capital, in the form of non-voting, convertible Series B preferred shares with an exercise price of $111.33 per common share [cc753d26].

The vesting mechanism is tied directly to Anthropic's own spending. Around 2 percent of the share capital vests with the initial commitment, while the remainder — according to the press release's framework — vests as expansions come in, at roughly 1 percent per additional $3 billion [cc753d26]. Unite.AI, which has reviewed the 8-K filing, specifies the tranches further: the warrant covers 387,051 preferred shares, each convertible into 20 common shares (7,741,020 shares on an as-converted basis). The first tranche of 40 percent vests upon Anthropic's first payment under Project Plan 3, and three tranches of 20 percent each vest successively for each additional $3 billion in committed contract value under the master agreement, which must remain in force [ad9fd1f1]. AIMag has not reviewed the 8-K filing itself, so these details rest on a secondary summary of the document.

This is an alignment mechanism both parties apparently need (the analysis below is AIMag's assessment, not information from the sources): for Akamai, the warrant rewards Anthropic for actually spending the $11.6 billion, not merely signing for it — extending the incentive across the contract's lifetime. For Anthropic, the warrant functions as a discount mechanism linking the company's cloud costs to the value of the vendor it becomes dependent on. CryptoBriefing estimates that full exercise of the warrant corresponds to approximately $857 million in potential equity value [f24fbd61].

Why a CDN giant is selling AI infrastructure

Akamai is historically known as a content delivery network (CDN), but in recent years it has built out a distributed cloud offering. The press release emphasizes that the agreement is meant to handle CPU workloads — not GPU-driven model training, which is dominated by hyperscalers such as Microsoft, Google and Amazon. It is worth noting (again, as analysis): Anthropic trains its models on other infrastructure, but inference and other CPU-intensive tasks have become a separate, rapidly growing market segment where distribution geographically closer to end users is an advantage. Akamai's edge network is a natural competitive advantage here [cc753d26].

Terms, termination and risk

According to Unite.AI's review of the 8-K filing, Anthropic can terminate the agreement upon a material, uncured breach by Akamai, or upon a change of control of Akamai in favor of a direct competitor of Anthropic — a clause reflecting how strategically dependent AI labs have become on their infrastructure providers [ad9fd1f1].

There is also a financial risk for Akamai: roughly $5.5 billion in capital expenditures against $11.6 billion in expected revenue yields a thinner margin than many other cloud contracts, and the 2026 pre-purchase of memory chips locks the company into a supply chain that has proven price-volatile. If Anthropic does not exercise the $9 billion expansion option, Akamai is left with a capital investment sized for a larger deal [cc753d26].

What we don't know

None of the available sources contain direct quotes or comments from Anthropic — all contextualization of the agreement comes from Akamai's side. Why Anthropic chose a CDN provider over a traditional hyperscaler, and how the warrant was valued in the negotiations, is unclear in the available material. And the exact size of the share move in extended trading should be verified against market data, given the discrepancy between the sources [ee044036, 4919f846].

The biggest open question is nonetheless whether such deals will become the norm: major AI players are signing multi-year infrastructure commitments on a scale previously reserved for nation-states and telecom companies, and equity linkages like this one suggest that buyers are no longer willing to bear the full counterparty risk alone.
