Anthropic is pursuing a simple but expensive strategy: reserve large amounts of AI computing capacity before it becomes unavailable. The resulting figures can look staggering, but they combine multi-year contracts with different start dates, hardware platforms, and cancellation terms. They should not be read as current annual spending—or as proof that every reported reservation will be delivered and used exactly as planned.
What is confirmed, reported, and still unclear
The claim that Anthropic has committed roughly $517 billion for at least 14.8 gigawatts aggregates a broad set of reported arrangements. The supplied evidence supports several major deals, but not a complete, independently verified total across every named partner. In particular, the available reporting does not establish definitive terms for claimed Microsoft and Riot Platforms agreements, and it does not provide a verified Claude Code revenue figure.
That distinction matters. A capacity deal can be a disclosed contract, a reported private agreement, an expansion option, or a planned build-out. Its headline value also may represent years of payments rather than cash paid up front.
The major compute agreements
SpaceX: an unusually specific payment schedule
Anthropic announced a SpaceX partnership in May 2026 to substantially increase capacity and lift usage limits for Claude Code and Claude’s API. 29 SpaceX subsequently disclosed the more concrete commercial terms: Anthropic agreed to pay $1.25 billion per month through May 2029 for compute across the Colossus and Colossus II AI training clusters. Fees were reduced during the May and June 2026 ramp-up period. Either party can terminate the agreements with 90 days’ notice.
34
At the stated monthly rate, the arrangement implies roughly $15 billion on an annualized basis and nearly $45 billion across about three years, before allowing for the initial reduced-fee period or an early termination. That is a commitment to future capacity, not evidence that Anthropic paid the full headline amount at signing.
Earlier reporting described the partnership as giving Anthropic access to more than 300 megawatts at Colossus 1 in Memphis. 41
Google and Broadcom: 3.5 GW of TPU capacity from 2027
In April 2026, Anthropic said it had signed a new agreement with Google and Broadcom for multiple gigawatts of next-generation Google TPU capacity, expected to come online beginning in 2027. Anthropic said the systems would train and run frontier Claude models in response to customer demand. 15
Reuters reported that the deal provides Anthropic access to about 3.5 GW of AI computing capacity using Google processors from 2027; the financial terms were not disclosed. 2 Separately, Broadcom’s arrangement with Google covers future TPU generations and components for next-generation AI racks through 2031.
2
Anthropic had already expanded its Google Cloud relationship in 2025. Reporting described access to as many as one million TPUs, with more than one gigawatt expected online in 2026, while Google Cloud characterized that earlier agreement as worth tens of billions of dollars. 3
Nscale: reported $45 billion over six years for 460 MW
Reuters reported in August 2026 that Anthropic would spend $45 billion to rent AI cloud computing power from Nscale’s West Virginia campus. The reported six-year agreement covers about 460 MW, with Nscale deploying Nvidia’s Vera Rubin chips. 17
The capacity is prospective rather than immediately available. Reporting said it was expected to begin powering Anthropic’s services in late 2027. 19 At a simple even-spend average, $45 billion over six years equates to about $7.5 billion per year—but real payment timing, milestones, minimum commitments, and termination rights have not been publicly detailed in the material provided.
Lambda: a reported $35 billion deal with limited disclosed terms
Several reports describe a $35 billion compute deal with Nvidia-backed Lambda. 20
21 One report associates it with about 350 MW of capacity at a Texas data center.
22
However, neither Anthropic nor Lambda had publicly announced detailed contract terms in the supplied reporting. That means the duration, payment schedule, delivery milestones, and any take-or-pay obligations should not be assumed from the headline value alone.
Microsoft and Riot Platforms: do not treat reported totals as settled terms
The material provided does not substantiate the claimed Microsoft or Riot Platforms deal sizes, capacity amounts, start dates, or contractual enforceability. They may be part of broader industry reporting around Anthropic’s infrastructure footprint, but a rigorous tally should exclude or clearly label them as unverified until supported by a company filing, announcement, or reliable direct reporting.
Why an Nscale anchor customer matters for an IPO
A reported six-year, $45 billion agreement would give Nscale a major anchor customer for a planned campus. That can strengthen a data-center operator’s case to lenders, suppliers, and prospective public-market investors: contracted demand helps support equipment procurement, construction financing, and long-term revenue visibility. Reuters described the deal as occurring as Anthropic prepared for a major IPO. 17
But contracted backlog is not collected revenue. Nscale must still build and commission the campus, secure power and interconnection, obtain hardware, and bring the systems into service. Anthropic must also continue to need—and pay for—the capacity. The supplied sources do not verify specific IPO valuation, backlog, or listing-timing figures, so those should not be presented as established facts.
What demand is driving the build-out
Anthropic’s own explanation for the Google/Broadcom expansion is demand for its frontier Claude models from customers worldwide, across both training and serving workloads. 15 Its SpaceX announcement paired the capacity agreement with higher Claude Code and API limits, including doubled five-hour Claude Code limits for several paid plans and the removal of peak-hours reductions for Pro and Max users.
29
Those product changes are evidence that Anthropic expected heavy usage. They do not, however, establish a particular Claude Code revenue number or quantify Claude Code’s contribution to the wider infrastructure expansion. The available record supports strong demand as Anthropic’s stated rationale, not a precise revenue-driven model of each capacity contract.
The core financial and operational risks
Revenue must catch up with reserved capacity
Long-term reservations can protect Anthropic from a shortage of chips and data-center power. They also create exposure if Claude demand, pricing, or market share fails to grow quickly enough. Underused reserved capacity can weigh on margins even when a company’s revenue is rising.
Delivery is not guaranteed by a headline commitment
Much of the reported capacity is still in the future: the Google/Broadcom TPU expansion is due from 2027, and the Nscale campus is expected to serve Anthropic from late 2027. 2
19 Data-center construction, electrical interconnection, chip supply, networking, and commissioning all create potential delays. A contract may reserve capacity, but it does not eliminate execution risk.
Cost of compute can outpace monetization
Training frontier models and serving high-volume inference are capital-intensive. Anthropic may have to fund deposits, capacity fees, model development, and operating costs before the associated products generate sufficient gross profit. The central question is not whether more compute can support Claude growth; it is whether customer revenue and pricing can cover the cost of that compute over time.
Contract value is not annual spending
The SpaceX and Nscale agreements make the accounting intuition clear. SpaceX’s reported $1.25 billion monthly schedule points to a far higher annualized run rate than Nscale’s $45 billion spread across six years. 34
17 Yet neither headline number means the full contract amount was paid upfront, recognized as an expense in the announcement year, or immune from contractual contingencies.
The bottom line
Anthropic’s infrastructure campaign is a bet that future demand for Claude will justify reserving capacity now. The best-supported agreements show a mix of immediately ramping capacity and large 2027-era build-outs: more than 300 MW associated with SpaceX, 3.5 GW of Google TPU capacity from 2027, and a reported 460 MW at Nscale. 41

17
The strategic logic is clear: compute, power, and data-center space can be bottlenecks for frontier AI. The financial outcome is less certain. Investors and customers should separate announced or reported total contract values from annual cash commitments, delivered capacity, and sustainable product margins.
