Nvidia Weighs Cosigning Billions in Nscale Debt for Anthropic's West Virginia Data Center
Nvidia is in talks to provide a residual value guarantee on Nscale's construction debt for a 460-megawatt facility Anthropic has contracted, after neoclouds were effectively shut out of the bond market.
Nvidia is in talks to guarantee billions in construction debt for Nscale’s 460-megawatt West Virginia data center, a facility Anthropic has contracted for a $44.6 billion first building per Nscale’s IPO filing, with a second building deal of roughly comparable size still in discussion. The mechanism under negotiation, as first reported by The Information and corroborated by Bloomberg, is a residual value guarantee: if Nscale defaults on the construction loan, Nvidia would take over the facility and work to find a buyer or new tenant rather than simply watching the asset go to the lender. In practice that makes the chip supplier the last party standing behind a multi-billion-dollar real-estate transaction it was not supposed to be in.
The reason Nvidia is being pulled into that position is straightforward. CoreWeave, Nebius, and Nscale have been effectively shut out of the bond market, which means the kind of institutional financing a 460MW build normally relies on is simply unavailable to them at the sizes they need. Nscale’s own numbers make the gap visible: the company posted a $1 billion net loss on $141 million in revenue in the first half of 2026, and Microsoft pulled out of a planned UK Nscale site this month. Against that, Anthropic’s August contract — worth more than 40% of Nscale’s $103 billion revenue backlog — includes a clause that lets the buyer walk away entirely if financing fails to close by a set deadline. Without someone willing to stand behind the debt, the building doesn’t get built, and Anthropic’s compute roadmap loses the building it was planning around.
The Anthropic deal itself is a large fraction of Nscale’s forward-looking position. The $44.6 billion first-building contract, together with the second building currently in negotiation, anchors a revenue backlog that makes Nscale one of the largest AI infrastructure providers by contracted value, even though the company is losing a billion dollars a half on the way to delivering. Nscale had roughly 25,000 advanced chips running as of August, against a plan to field around 500,000, which is the scale gap the West Virginia site and its successors are meant to close. The gap between chips in the rack and chips on the roadmap is exactly the gap a construction loan is supposed to bridge, and exactly the gap that is now bridged, if at all, by the vendor of the chips themselves.
Nvidia’s exposure to the neocloud layer is not a one-off. The company has extended roughly $170 billion in investments and credit support across neocloud customers, including a $1 billion convertible note issued to Nscale in September. Blackstone has warned that Nscale’s eventual public listing may come with a below-investment-grade rating, and Nscale is now targeting a December IPO at a valuation bankers are already flagging as at risk in the $30-35 billion range. The residual-value guarantee does not change the company’s standalone credit profile; it inserts Nvidia’s balance sheet between Nscale’s lenders and the default, which is the same economic position a project-finance sponsor takes, except that the sponsor here is the company selling the equipment the project was built to house.
Anthropic filed for its own IPO this week, which puts the counterparty to the $44.6 billion contract on the public markets as well. Whether that strengthens or weakens the financing position for the West Virginia build depends on how the market prices the AI-lab’s revenue durability, but the walk-away clause in the contract means the question of whether the building gets financed at all is still live even after the Anthropic deal is signed. Nscale’s target of a December listing, with a valuation that bankers at the $30-35 billion mark are already calling at risk, sits in the same window — a few months in which the company needs to close its public capital raise, demonstrate that the chip count is actually climbing toward 500,000, and convince a bond market that has told it no that a 460MW West Virginia data center is investable. Unless Nvidia’s guarantee closes the gap, the deadline Anthropic set for financing may well become the deadline at which the whole arrangement simply doesn’t happen.
