Akamai signs seven-year, $11.6bn compute lease with Anthropic

Akamai has signed a seven-year agreement to lease compute capacity to Anthropic, a contract it values at $11.6bn and says could expand by as much as $9bn more, for a total potential commitment of roughly $20bn. The deal, reported by Data Center Dynamics, covers CPU workloads on Akamai Cloud's distributed infrastructure and software, and Akamai estimates about $5.5bn of capital expenditure against that revenue, about $1.7bn of it pulled into 2026 to secure and pre-purchase critical supply-chain components, memory among them.

Spread evenly, the $11.6bn base would pay Akamai around $1.66bn a year, within rounding of the $1.7bn in components the company expects to pre-buy in 2026 alone; the release does not disclose whether the payment schedule is level, nor how the $5.5bn of capex relates to the base commitment versus the $9bn expansion it describes as potential rather than committed. On those figures, Akamai is underwriting roughly two dollars of contracted revenue for every dollar of capital before any expansion vests, a ratio that widens to about three and a half times stated capex at the full $20bn — on paper, and only if the customer exercises.

The less ordinary term is the equity: Akamai issued Anthropic a warrant for up to about 5% of its common stock outstanding, with continued vesting tied to expansion of the agreements and a portion representing about 2% of shares outstanding expected to vest with the announced commitment. No strike price appears in the release, so the warrant cannot be valued from what has been published, and the release does not say how Akamai funds the $5.5bn — operating cash, debt, or some combination. Read literally, the vesting schedule is a schedule of future capacity purchases: the customer's ownership stake grows only as its order book does.

We have seen a version of this structure, reversed. When Anthropic's data center arm hired the architect of Equinix's hyperscale joint ventures, we described a structure that stacked credit on a single demand forecast by putting the customer inside the capital stack. Akamai's warrant applies that logic from the supplier's side, swapping an equity claim for a deposit or a lease guarantee and letting the customer earn more of it by consuming more capacity; whether that compensates a below-market lease, pays for scarce capacity, or both, the announcement does not say.

Akamai said the Anthropic agreement is additional to more than $2.8bn in multi-year cloud commitments it has secured this year, and it presents the two as separate, putting the lease outside that figure rather than inside it; on the reported numbers, one seven-year contract is roughly four times everything else in this year's cloud commitments.

Anthropic is meanwhile buying capacity from more than one direction: our September coverage of its data center arm described a group built to develop its own sites, while the Akamai contract rents someone else's. Both can be true at once, but the combination suggests a developer not waiting for its own buildout to catch up with demand — an inference from the two announcements rather than a plan either company has stated.

We usually draw the line between digital infrastructure's contracted core and its speculative edge across companies; here it runs through one balance sheet — a named counterparty, a stated term and a dollar value on the base tranche, the profile that earns infrastructure treatment, attached to capex that has not yet been earned and an expansion option the customer holds. As we argued in September, the customer and the state are the two buyers left in AI infrastructure finance, and this deal belongs to the customer column, with the release naming no guarantor.

Compute commitments are being assembled at mid-cap acquisition scale — SpaceX's $41.1bn book across four counterparties, the contractual obligations sitting behind every GPU-cloud balance sheet — and the multi-year lease has become the instrument financing the buildout. Akamai's version puts a slice of the supplier's equity on the other side of the ledger, vesting in tranches to keep the customer buying, and the announcement does not say who owns the hardware when the seven years are up, which is the question a term that long leaves open.

The clearest external marker is the vesting: if the remaining portion of the warrant vests, Anthropic has expanded its commitment to Akamai, likely before the added revenue appears in reported cloud results. The other is the capex line, where $1.7bn for components and memory in 2026 is committed ahead of the first year of billing, suggesting the constraint Akamai is paying to relieve sits upstream of its own racks.
