The Anthropic Nscale $45B deal West Virginia compute agreement, disclosed in late August, is now the single largest contract in Nscale’s reported $51 billion revenue backlog and the headline asset bankers will lead with when the UK infrastructure company pitches its September initial public offering to public-market investors. Anthropic has agreed to pay $45 billion over six years for 460 megawatts of capacity at Nscale’s Monarch Compute Campus in Mason County, West Virginia, replacing Microsoft, which walked away from a much larger 1.35-gigawatt letter of intent at the same site earlier in the summer.
Anthropic Nscale How the Monarch Compute Campus Came Together
Monarch sits on 2,250 acres that Nscale acquired in March 2026 when it purchased American Intelligence and Power Corporation from developers Fidelis New Energy and 8090 Industries. The campus has been positioned as the United States’ first state-certified artificial intelligence microgrid, with total power potential described by Nscale as scalable beyond eight gigawatts. West Virginia’s House Bill 2014, signed in 2025, gave the project its regulatory backbone by allowing data centers to operate as microgrids and preempting local zoning and noise ordinances in favor of a unified state standard. Governor Patrick Morrisey publicly endorsed the acquisition, citing the law as the enabling framework.
Why Microsoft Left and Anthropic Stepped In
In March 2026, Nscale used the announcement of a letter of intent with Microsoft, covering up to 1.35 gigawatts at Monarch, to anchor its Nvidia GTC 2026 debut and simultaneously close what it called the largest Series C in European history at a $14.6 billion valuation. A letter of intent is generally not legally binding, a reservation with optionality rather than a committed payment stream. Bloomberg reported that Microsoft exited the arrangement earlier in the summer, opening the first building of a three-building first phase to a new tenant. Microsoft has not publicly explained the decision and declined to comment on the Monarch situation, though sources noted the company has grown more selective about locking in specific site commitments while continuing to spend at scale elsewhere.
Anthropic reportedly signed a binding agreement in Microsoft’s place. The deal was confirmed through a regulatory disclosure from Aker ASA, a Nscale Series C investor that described Nscale as its second-largest portfolio holding and disclosed the $45 billion contract at Monarch. The 460-megawatt figure corresponds to the first of three buildings in Monarch’s planned first phase, with the remaining two buildings expected to come online in 2028.
What Anthropic Is Actually Buying
The hardware slated for Monarch is Nvidia’s seventh-generation Vera Rubin platform, specifically the NVL72 rack configuration. A single NVL72 chassis integrates 72 Rubin GPUs alongside 36 Vera CPUs in a fully liquid-cooled assembly, delivering 3.6 exaflops of NVFP4 inference throughput and 2.5 exaflops of training throughput per rack. A complete 40-rack Vera Rubin POD scales to 1,152 Rubin GPUs and roughly 60 exaflops of aggregate compute, a figure that exceeds the capacity of any prior publicly known supercomputer built specifically for AI workloads. Vera Rubin chips have not yet shipped at commercial scale, and Nscale’s capacity is expected to start coming online in late 2027.
What powers those chips matters as much as the chips themselves. Unlike Norway’s Bitdeer and Tydal campus, which benefits from hydroelectric generation and a power usage effectiveness ratio near 1.1, Monarch will run on a natural gas microgrid. According to a West Virginia Department of Environmental Protection permit application, the first phase will rely on 864 Caterpillar G3500 reciprocating engines, plus 120 additional units for emergency power, fire suppression, and heating, for a combined generation capacity of 2.16 gigawatts. Operating entirely off the local grid insulates Mason County utility customers from rate or supply impacts, but it also means the campus’s carbon footprint is determined by its gas consumption rather than by renewable energy certificates. Environmental advocates including the Sierra Club’s West Virginia chapter and Tucker United have raised concerns about emissions from large-scale natural gas generation across several West Virginia data center projects, and a May 2026 DEP inspection documented dust clouds at the Monarch construction site.
Nscale’s IPO Pitch, Examined
For Nscale, the Anthropic contract is transformational in the specific sense that matters most to bankers preparing a prospectus. It is a large, named, long-duration revenue commitment from a creditworthy counterparty, signed weeks before the company needs institutional investors to evaluate whether its growth trajectory is real. Nscale has told prospective IPO investors it holds approximately $51 billion in total contracted revenue, and Goldman Sachs and JPMorgan are leading the planned September listing. Developing the entire campus, first phase plus the full eight-gigawatt potential, is projected to cost approximately $71 billion, with roughly $47 billion of that representing chip procurement.
Two pre-IPO companies now share a mutual dependency. Anthropic’s compute spending is the revenue anchor that makes Nscale’s IPO story credible, and Nscale’s ability to deliver on schedule is what determines whether Anthropic has 460 megawatts of Vera Rubin capacity available in late 2027. Both sides are betting that the other side will hold up its end of a deal that, on paper, dwarfs anything else in Nscale’s backlog and reshapes the competitive landscape for hyperscaler-style AI compute. The Anthropic Nscale $45B deal West Virginia compute agreement is the clearest signal yet that the AI infrastructure boom has moved into a phase defined by who can lock in multi-year gigawatt commitments rather than who can buy the most chips in any single quarter.
