Anthropic's $34.9 billion Lambda compute deal becomes terminable after a missed lease deadline

Anthropic has disclosed that one of its largest cloud contracts can now be ended by either side. In a second amendment to its IPO registration statement, filed on 10 November 2026, the company says Lambda did not secure the lease for the facility meant to host the capacity by the date the agreement set. As a result, the August 2026 agreement, worth about $34.9 billion, is currently terminable by either party. The filing adds that neither side has sent a termination notice and that Anthropic does not currently intend to give one.

The change is a matter of timing. The first amendment, filed on 2 November, described the same right only as a contingency that would arise if Lambda failed to secure the lease on time. Eight days later the filing reported that the condition had been met. The documents name neither the facility nor the missed deadline, and neither company has said publicly why the lease slipped. The size of the deal matches a roughly $35 billion arrangement that the Wall Street Journal reported on 1 September, covering about 350 megawatts at a Hut 8 data center in Nueces County, Texas, with Nvidia holding the lease. TokenPost places the capacity at Hut 8's Beacon Point site in the same state.

“Neither party has delivered notice of termination as of the date of this prospectus, and we do not currently intend to terminate the agreement”

Anthropic has three Lambda agreements, signed in May, June and August 2026, for Nvidia GPU compute with terms running into 2034. Together they come to about $41.3 billion of spending, so the August deal is roughly 84.5 per cent of what Anthropic has agreed to spend with Lambda, and about 3.9 per cent of its total committed spend. Fees accrue only as capacity is delivered to and accepted by Anthropic, which is why waiting costs the company nothing in the meantime. Outside the August clause, the contracts can be cancelled only for an uncured material breach or in limited cases, and some can be trimmed tranche by tranche if Lambda misses delivery milestones.

The amendment shifted other numbers in the filing. Anthropic's minimum commitment to Microsoft rose to at least $47.2 billion, and up to $49.2 billion, running from November 2026 to June 2033, up from at least $44.9 billion on 2 November. Its Google hosting commitment is unchanged at about $121.3 billion through July 2033. Total commitments grew to about $900.9 billion from $895.4 billion. Commitments that carry termination rights or unmet conditions fell to $186.2 billion from $213.8 billion, a drop of $27.6 billion, or 12.9 per cent, which the filing does not explain. Commitments signed after 30 September rose to about $105.7 billion from $100.2 billion, and The Information reported that about $10 billion of new Microsoft and Google commitments sit behind that. The filing also estimates $150 billion to $175 billion of payments under deals with no fixed amount, such as Google TPU capacity and AMD Helios systems.

For Lambda the news arrives at a busy moment. It is an AI-focused cloud company that rents Nvidia GPUs to developers, and its backlog grew from about $15 billion in June to about $50 billion by September. It has been seeking up to $4 billion ahead of a possible 2027 listing, and on 4 November announced a planned $33.1 billion campus in Lowndes County, Alabama, an announcement that does not mention Anthropic. Anthropic's three GPU cloud deals with SpaceXAI, Nscale and Lambda total up to about $206.4 billion, and each carries termination rights. CNBC has also reported that Microsoft plans to use fewer neoclouds, naming Lambda and Nscale.

Commentators on X argued that cancelling would cost Anthropic capacity it could not easily replace and would push it toward costlier short-term compute. Whether either side serves notice, or the lease is secured later, remains open, and no date is given. The same filing sets a price range of $70 to $78 a share for the offering, with 135.1 million placement shares calculated at the $74 midpoint. Amazon's holding is unchanged at 1,920,511,218 Class N shares, while Google's rose to 1,789,598,269 after it bought $10 billion in the private placement. Offering expenses are estimated at $67.7 million, including $41.5 million in legal fees.
