Anthropic Compute Commitments Reach $900.9B as Microsoft Deal Grows
Anthropic's amended IPO filing puts compute commitments at about $900.9 billion, with roughly $186.2 billion subject to termination rights or conditions.
Listen
Anthropic compute commitments total about $900.9 billion in the company's amended IPO filing, submitted on November 10, 2026. The most recent change raises the Microsoft Azure minimum by up to $4.3 billion, to between $47.2 billion and $49.2 billion through June 2033. Reported figures put about $186.2 billion of the total under termination rights or conditions, against a reported run-rate of $81 billion, so the headline number overstates how much of the bill is firm.
What the amended filing changes
The commitment runs from November 2026 through June 2033 and applies regardless of usage. Google accounts for about $121.3 billion over 2026 to 2033, Amazon for about $110 billion over 2026 to 2036, and SpaceX for $120.5 billion.
The filing also describes a shift in how Anthropic gets capacity. Rather than buying only cloud hosting, the company is leasing hardware and installing it in private facilities run by outside operators, with Nvidia Vera Rubin NVL72 systems and Google TPU capacity singled out as key equipment. Reported signed leases that have not yet started account for $451.2 billion, or about half of the total, with an average term of about 10 years.
Which commitments can be cancelled
The Lambda agreement is the clearest example of a conditional commitment. The $41.3 billion deal became terminable once Lambda could not obtain a necessary facility lease. Separately, the $34.9 billion agreement due in August 2026 can now be ended by either side. Anthropic has said it does not currently intend to terminate it, and neither party has delivered notice.
Reported terms place the $120.5 billion SpaceX deal under cancellation on 90 days' notice from early 2027. According to the same reports, contracts with Google, Amazon, Microsoft and Broadcom, totaling roughly $440 billion, carry take-or-pay or non-cancelable terms. Even as the overall total rose, the portion open to termination rights or conditions shrank.
Spending is already rising faster than revenue. Compute expenses reached $9.9 billion in Q3 2026, compared with $944 million in Q1 2025, more than tenfold in six quarters. Anthropic attributed an operating loss of $567 million in the third quarter, after an operating profit of $974 million in the prior quarter, primarily to short-term compute deals. Of the reported run-rate, about 87 percent corresponds to $70.7 billion in payments that come due within the 12 months following September 30.
Trade-offs for buyers and host communities
Short-term and cancellable capacity gives Anthropic room to move as its needs change, and it lowers the cost of backing out of a single supplier. The trade-off is that the supplier carries the build-out risk, and a missed facility lease can unwind a multi-billion-dollar agreement, as the Lambda case shows. For cloud rivals, the take-or-pay contracts provide a firmer revenue base than the conditional ones.
That gap matters because $451.2 billion in leases that have not started will place large electricity and water loads in specific locations over the coming years.
The headline figure is a contract total, not a spending schedule, and the filing itself warns that much of the capacity is still undelivered, so timing and amounts may move. The next checks are the start dates of the leases expected between 2026 and 2028, whether the Lambda facility lease is resolved, and whether the SpaceX deal is cancelled after its early 2027 window opens. Those dates will show how much of the $900.9 billion becomes physical capacity in nearby communities.
