Akamai signs $11.6bn Anthropic deal for AI cloud infrastructure
Akamai Technologies has announced a seven-year contractual commitment worth $11.6 billion with AI safety company Anthropic, under which Anthropic will use Akamai's distributed cloud infrastructure to support its growing CPU workload demands. The deal, disclosed on 24 September 2026, represents one of the largest cloud infrastructure agreements in the sector and marks a significant strategic pivot for Akamai, which has historically been known for content delivery and edge network services rather than hyperscale AI compute.
The agreement carries an option to expand by up to a further $9 billion within the same seven-year term, bringing the total potential commitment to approximately $20 billion. Each incremental $3 billion in cloud services purchases, at mutually agreed terms, would trigger additional expansion tranches.
Warrant structure and equity alignment
Alongside the commercial contract, Akamai has issued Anthropic a warrant to purchase non-voting convertible Series B Preferred Stock equivalent to 7.7 million shares of Akamai common stock on an as-converted basis, representing up to approximately 5% of outstanding common stock at an exercise price of $111.33 per share. Roughly 2% of the common stock equivalent is expected to vest upon completion of today's commitment, with the remaining approximately 3% vesting progressively as Anthropic expands its purchases toward the $9 billion ceiling.
Total capital expenditure tied to the initial $11.6 billion commitment is estimated at approximately $5.5 billion, with Akamai flagging an additional $1.7 billion in 2026 capex to secure supply-chain components including memory. The company said this has no impact on its existing 2026 revenue guidance.
Tom Leighton, co-founder and chief executive of Akamai, said the company's "expanding global footprint, combined with our years of experience serving the world's largest enterprises, positions us to be the infrastructure provider for secure and responsible AI applications and workloads."
Market context and competitive positioning
The deal lands in a fiercely competitive market for AI infrastructure, where the hyperscalers (AWS, Microsoft Azure, Google Cloud) control the dominant share of AI training and inference capacity. Akamai is positioning itself as a distributed alternative, emphasising its thousands of points of presence and its ability to serve compute from core to edge rather than from a handful of large centralised facilities. For Anthropic, which has previously disclosed major cloud commitments with both Amazon Web Services and Google Cloud, the Akamai arrangement appears focused on CPU-intensive workloads, suggesting complementary rather than substitutive infrastructure use.
The deal adds to what Akamai describes as more than $2.8 billion in previously announced multi-year Cloud Infrastructure Services commitments elsewhere in its customer base this year, signalling a deliberate strategic repositioning. Akamai's CDN heritage gives it a credible claim on latency-sensitive, geographically distributed workloads, though investors and customers will watch closely to see whether it can deliver hyperscale reliability for AI applications at the volumes this agreement implies.
Regulatory and financial read-across
The warrant structure and the scale of the commitment mean this transaction is likely to attract close attention from securities analysts and potentially from competition regulators in both the US and EU, given the concentration of AI infrastructure relationships across a small number of cloud and AI companies. The equity-linked component, while described as non-voting preferred stock, introduces a degree of financial interdependence between an infrastructure vendor and a model developer that has few precedents at this scale.
Akamai said it will host an investor call the same day. Anthropic had not issued a corresponding statement at time of publication.
