Anthropic / 24 September 2026

Anthropic commits $11.6 billion to Akamai cloud capacity

Anthropic committed about $11.6 billion over seven years for Akamai cloud services in a deal publicly announced on 24 September, with a warrant that could give the Claude developer as much as roughly 5% of Akamai's common equity on conversion and exercise. Akamai says the capacity will serve Anthropic's growing CPU workload, an important detail amid attention focused almost entirely on AI accelerators. The initial commitment is tied to about 2% of Akamai's shares through the warrant, while the remaining approximately 3% would vest if Anthropic expands the arrangement by another $9 billion. The agreement secures a substantial infrastructure option and links Anthropic's purchasing decisions to potential ownership in a supplier.

Akamai's SEC filing says the two new project plans were signed on 18 September under a master agreement dating from May, but the transaction was announced to the market on 24 September. The seven-year terms begin when the respective services start. Payments depend on delivery and service availability conditions, and the contract permits termination in specified circumstances including uncured breaches and certain material outages. These details distinguish the reported commitment from immediate cash spending or capacity already in production. Akamai expects about $5.5 billion in capital expenditure to support the initial $11.6 billion contract, including roughly $1.7 billion of 2026 outlay to secure and pre-purchase components such as memory. It said its 2026 revenue forecast would not change.

The warrant is not a free transfer of 5% of Akamai. Anthropic would have the right to buy non-voting convertible preferred shares at an exercise price equivalent to $111.33 per common share, and must pay cash to exercise vested portions. The first tranche, representing about 2% of common shares, vests after an initial payment under one project plan, subject to conditions. Each further $3 billion of agreed cloud commitments releases approximately another 1% of shares, up to the stated additional $9 billion. The structure gives Anthropic potential upside if Akamai's business grows, while giving Akamai a powerful incentive to expand its customer relationship. The cost of exercising and dilution still matter to both parties.

Akamai chief executive Tom Leighton said Anthropic chose its capabilities for ‘building and operating AI infrastructure at scale.’ The company describes a globally distributed cloud spanning thousands of points of presence and says its hardware mix can support applications from core to edge. Reuters reported that Akamai's shares rose sharply after the news, but the durable business fact is the contracted workload and associated capital plan. The deal also sits alongside Anthropic's earlier $45 billion arrangement for AI cloud power at Nscale's West Virginia campus. Anthropic's IPO prospectus, reported later, describes hundreds of billions in infrastructure obligations across partners. Akamai adds another supplier and a different CPU-oriented workload to that broader supply portfolio.

For Anthropic, securing general-purpose computing at scale can support the data processing, orchestration, storage and application services around Claude, not merely the accelerator that runs a model. For Akamai, the arrangement brings a large anchor customer but requires substantial early spending before the seven-year service stream is earned. The equity warrant aligns incentives while making the full 5% stake contingent on a much larger expansion. Neither side presented the optional $9 billion as a signed present commitment. The filing supplies unusually concrete terms about delivery, payment, vesting and the right to terminate on outages, allowing a clearer assessment of how the parties share execution risk as infrastructure is built and consumed.
