A $4 billion pre-IPO round from Blackstone and Coatue is being sold against that same backlog. ## A missed lease date opened a $34.9 billion door [Anthropic](https://theinference.org/markets/companies/anthropic), the AI company behind the Claude models, filed [the second amendment to its IPO registration](https://www.sec.gov/Archives/edgar/data/2130357/000162828026072484/anthropicpbc-sx1ax2.htm) on November 10, 2026 [1]. It discloses that [Lambda](https://theinference.org/markets/companies/lambda), a GPU cloud provider backed by [Nvidia](https://theinference.org/markets/companies/nvidia), missed the contractual date to secure the facility lease behind their August 2026 agreement, so that agreement, about $34.9 billion of the roughly $41.3 billion Anthropic has contracted to spend with Lambda into 2034, "is currently terminable by either party" [1]. Neither side has served notice, and Anthropic says it does "not currently intend to terminate the agreement" [1]. ## The option sits under a live fundraising Lambda is mid-raise: having [sold $1 billion of GPU-backed debt in October](https://theinference.org/article/lambda-sells-insurers-1-billion-of-gpu-debt-at-6-78-for-30-000-nvidia-chips), it is seeking up to $4 billion at a $14.5 billion pre-money valuation in a final round before a planned 2027 IPO, led by the investors [Blackstone](https://theinference.org/markets/companies/blackstone) and Coatue, the Wall Street Journal reported on October 6 [2][3], and the round was still being marketed this week [4]. [A letter to Lambda's investors](https://techcrunch.com/2026/10/06/ai-computing-startup-lambda-to-raise-4b-ahead-of-planned-ipo/), reviewed by the Journal, put its backlog at $50 billion in September, up from $15 billion in June, mostly the Anthropic commitment [2][3]. Anthropic is roughly 70% of that backlog, by one estimate [5]. ## A walk would land on Hut 8 and Nvidia The filing names no site; its size and timing match [roughly 350 megawatts of Anthropic capacity](https://www.msn.com/en-us/technology/tech-companies/nvidia-anchors-hut-8-s-texas-campus-in-anthropic-s-35-billion-cloud-deal/ar-AA2bn2CB) reported at Beacon Point, the campus the data-center developer [Hut 8](https://theinference.org/markets/companies/hut-8-mining) is building in Nueces County, Texas [6][7]. Nvidia sits on three sides of the same trade at once: Lambda's investor, its chip supplier, and the leaseholder on that campus, where its leases are worth up to $50 billion [6][7]. Hut 8 has contracted 704 megawatts there in two 15-year leases worth $19.6 billion at base, up to $50.2 billion with renewals, and has named its tenant only as a high-investment-grade counterparty [7]. ## A fifth of a $900.9 billion book can still leave Anthropic's total committed spend is about $900.9 billion, and $186.2 billion of it sits behind exercisable termination rights or unmet conditions, such as a counterparty securing a facility [1]. The same filing raised the floor on what Anthropic cannot escape: [at least $47.2 billion to Microsoft through June 2033](https://mlq.ai/news/anthropics-amended-s-1-says-its-35-billion-lambda-compute-deal-can-now-be-cancelled-and-raises-its-microsoft-commitment/) regardless of usage, up from $44.9 billion in the November 2 version [1][6]. The named book splits three ways: hard minimums from Google, [Amazon](https://theinference.org/markets/companies/amazon) and [Microsoft](https://theinference.org/markets/companies/microsoft); delivery-dependent ceilings from SpaceXAI, the [SpaceX](https://theinference.org/markets/companies/spacex) subsidiary formerly called [xAI](https://theinference.org/markets/companies/xai), and the GPU cloud [Nscale](https://theinference.org/markets/companies/nscale); and Lambda's $41.3 billion [1]. *Chart: **Hard minimums, delivery caps and one no-cause exit: Anthropic's named compute commitments** Bar chart of Anthropic's named compute commitments: Google CSP hosting $121.3B minimum, SpaceXAI $120.5B ceiling, Amazon $110.0B minimum, Microsoft $47.2B minimum, Nscale $44.6B ceiling, Lambda $41.3B contracted total, with Lambda highlighted as the only one terminable without cause.* *Committed spend under agreements named in Anthropic's S-1/A No. 2, filed November 10, 2026, in billions of dollars. Minimums are payable regardless of usage; ceilings are 'up to' totals that bill as capacity is delivered; Lambda is the May, June and August 2026 contracted total. [1]* ## The option outlasts the stated intention Fees accrue only as capacity is delivered and accepted, so Anthropic pays nothing for megawatts that never arrive [1]. Staying can also be read as confidence in Lambda's delivery [5]. But "currently" is the operative word, and a stated intention does not change the contract; neither company has said why the lease slipped [1][6]. Three tells settle it: Lambda secures the lease or a termination notice lands; the Blackstone round closes or reprices; and Anthropic prices its 825 million Class A shares inside the $70 to $78 range set in the same filing [1]. The $50 billion backlog counts as revenue only while Anthropic chooses to stay [1]. ## Takeaway A missed lease deadline made $34.9 billion of Anthropic's Lambda commitment terminable by either side, and that option now hangs over the $4 billion pre-IPO round being sold against the same backlog. ## Sources 1.
