Anthropic Lambda Deal Adds $35 Billion of Nvidia-Backed Compute

A $35 Billion Lease in South Texas

Anthropic has signed a $35 billion agreement to rent computing capacity from Lambda, a cloud provider backed by Nvidia, as it tries to add AI capacity fast.3 The Wall Street Journal reported the deal first, and Bloomberg confirmed it with a person familiar with the matter.3 Reuters' source said the contract covers about 350 megawatts at a data center that Hut 8, a bitcoin miner turned AI data center developer, is building in Nueces County, Texas.8 Several outlets describe it as a six-year agreement.13 Anthropic declined to comment on the deal. Nvidia, Lambda and Hut 8 did not respond at first.12

The Lambda contract was not a one-off. A few days earlier, Anthropic agreed to spend about $45 billion over six years leasing roughly 460 megawatts from Nscale at a West Virginia campus that will run Nvidia's Vera Rubin chips.7 That facility is expected to come online at the end of 2027.7 Anthropic has also reportedly signed a $50 billion agreement with Fluidstack, and its arrangement with SpaceX has grown into one of its largest.12 On its own, $35 billion would be a landmark contract for most companies. For Anthropic it was the fourth large compute lease of 2026.16

Nvidia on Every Side of the Deal

What stands out about the Lambda deal is its structure, not its size. Nvidia supplies the GPUs, owns part of Lambda, and had already signed an agreement with Hut 8 to take part of the Texas campus's capacity.9 Hut 8 says the campus, called Beacon Point, is planned for 1 gigawatt in total. Two 15-year leases of 352 megawatts each, signed in May and July, carry about $19.6 billion in base contract value.9

The coverage agrees that Nvidia is closely involved. It does not agree on exactly how. The Journal reported that Nvidia itself would hold the lease on the building.38 One summary describes a chain in which Hut 8 builds, Nvidia leases, Lambda subleases and Anthropic consumes the compute.13 Another analysis says Lambda holds the lease while Anthropic only rents compute.16 Nvidia has not confirmed the lease arrangement in public. It has pointed instead to its DSX reference architecture, which it uses to coordinate power, cooling and networking across the data centers it helps build.17

The most likely explanation is that the lease details are still unsettled in public reporting. The Journal's account, that Nvidia holds the lease, is the most widely repeated, and the other versions mostly add layers to it. Either way, the reason for the structure is clear. Neither Anthropic nor Lambda has a balance sheet strong enough to make a developer comfortable signing a long lease worth tens of billions of dollars. Nvidia's balance sheet is strong enough.17 With Nvidia as the anchor, Hut 8 gets an investment-grade tenant, Nvidia guarantees that its chips will be installed, and Lambda gets space on a gigawatt-scale campus without having to raise that capital itself.17

Adding Up the Spree

Cumulative totals differ depending on what gets counted. Some tallies put Anthropic's 2026 compute commitments at about $135 billion after the Lambda deal.1316 Others reach roughly $175 billion by adding the Lambda, Nscale, Fluidstack and SpaceX contracts together.17 In late September, Nvidia said Anthropic had secured about 2.6 gigawatts of AI infrastructure worth more than $180 billion through traditional and newer cloud providers, with delivery expected by the end of 2028.14

Anthropic's confidential IPO prospectus, as reported by Reuters, makes all of these figures look small. The company expects to spend at least $518 billion with six infrastructure partners over the next decade. About 80% of that is non-cancelable or owed regardless of how much Anthropic actually uses.19 The commitments include at least $111.1 billion to Google, $110 billion to Amazon and $31.4 billion to Microsoft. There are also about $161.2 billion in equipment lease obligations tied to Broadcom, and up to $84.5 billion with SpaceX's xAI unit.20 The SpaceX figure is close to double the roughly $45 billion that SpaceX disclosed in its own filing. Unlike the hyperscaler contracts, most of the SpaceX agreements can be ended with 90 days' notice.20

Later reporting puts Anthropic's data center leases at about $530 billion. The company is reportedly pushing partners to build faster, and it has signed an unannounced multiyear agreement with IREN, another former bitcoin miner.24 The reported dollar figures vary from outlet to outlet, but the direction is the same in all of them.

Why Compute Comes First for Anthropic

The prospectus explains the spending more plainly than any press release. Anthropic told investors that demand for advanced AI will probably outstrip supply, and that its growth will be limited "principally by the availability of compute."20 Reuters reported that Anthropic hit a compute shortage earlier this year as use of Claude and Claude Code grew, which led to the rush of long-term deals.9 Reuters' source said the Lambda capacity is meant to bring more Nvidia hardware online to meet demand for Claude.8

The Information has tried to put a number on the urgency. By its estimate, bringing one 245-megawatt site online a month early would add more than $1.3 billion in revenue for Anthropic.2 If that holds, compute is not only a research input. Each delayed megawatt is lost revenue, and that changes how a lab weighs cost against speed.

Users are already seeing the effect. Co-founder Tom Brown said Anthropic was scaling up on Nvidia GB200 capacity at SpaceX's Colossus 2. The extra capacity led to looser limits, including doubled five-hour rate limits on Claude Code for paid plans.20 Dario Amodei has tied the AWS expansion to this tension directly, saying Anthropic needs infrastructure that keeps up with demand so it can keep advancing its research while serving customers.1

The two needs pull against each other. Frontier labs must reserve capacity to train the next generation of models and also serve a fast-growing customer base on the current one. Anthropic's answer appears to be to buy almost everything it can find.

A Hedge Across Many Chips

The Lambda deal adds to Anthropic's Nvidia exposure, but it is part of a wider spread of chip suppliers. Anthropic has committed more than $100 billion over ten years to AWS for up to 5 gigawatts, covering Trainium2 through Trainium4. It already uses more than a million Trainium2 chips to train and serve Claude.1 Data Center Dynamics reports a $200 billion agreement with Google and more than 10 gigawatts of committed cloud servers in total.18 AMD will supply more than $20 billion in compute and buy up to $5 billion of Anthropic stock.20 Akamai, meanwhile, signed an $11.6 billion, seven-year deal centered on CPUs, the general-purpose chips whose demand has grown as AI agents take on more tasks.5

The prospectus also describes a shift from relying only on cloud providers toward dedicated data centers and directly leased chips. It names dependence on Amazon, Google and Microsoft as a major risk, because each of them is an investor, customer, sales channel and competitor at once.20 Seen this way, the deals with Lambda, Nscale and IREN are partly a hedge against the hyperscalers. The new landlords mostly bring scarce grid connections rather than long operating histories.216

The Circular-Financing Question

The main criticism of the Lambda deal is circularity. Nvidia committed up to $10 billion in equity to Anthropic in November 2025. It is also reportedly in talks to anchor as much as $10 billion of Anthropic's planned IPO.11 It is an investor in Lambda, Nscale and Volta, all of which are filling their data halls with its racks.16 When a chipmaker funds the buyers of its own chips, some of the demand it reports is demand it created.11 Nvidia's disclosures show $279 billion in supply obligations and $108.5 billion in guarantee obligations tied to cloud and data center partners.11

The risk works in both directions. Nvidia's backing makes the Texas campus financeable now, but it also leaves Nvidia exposed to whether Anthropic's usage keeps growing.17 Anthropic carries the same risk from the other side. Its 2025 revenue was close to $4.6 billion, and its operating loss was more than $8 billion.20 A company of that size is now owed capacity that could, under some deals, run into the hundreds of billions of dollars.

Overall, the Lambda deal shows Anthropic treating compute as the bet the company depends on, with Nvidia willing to stand behind that bet more and more directly. If Claude demand keeps rising, these leases will look like foresight. If it slows, the guarantees connecting Anthropic, Nvidia and a group of former bitcoin miners will be tested together. The outcome depends on whether revenue can keep pace with the bills.
