Bloomberg reported, citing people familiar with the agreement, that AI developer Anthropic has signed a $45 billion compute capacity agreement with Nscale, leasing 460MW — megawatts, a measure of electrical draw — for six years at Nscale’s Monarch Compute Campus in West Virginia. The contract is said to cover Nvidia Vera Rubin accelerators at the site, expected to come online in late 2027. Nscale had not publicly confirmed the contract at the time of the report.

Nscale acquired the 2,250-acre Monarch site in March 2026 and has described a potential build-out of up to 8GW, with a first phase of 2GW targeted for the first half of 2028 and power supplied by Caterpillar G3500-series fast-response natural gas generator sets. Microsoft has separately signed on for 1.35GW at the same campus, based on Nvidia Vera Rubin NVL72 racks. Nscale is preparing an initial public offering that reports have put at around $3 billion.

Executive Summary

The headline number is the story’s least interesting part. At $45 billion for 460MW over six years, the reported agreement prices out at roughly $16 million per megawatt per year, or about $1,360 per kilowatt-month on straightforward arithmetic. Wholesale data center space, even purpose-built for AI densities, rents for a small fraction of that. The gap is the tell: this is not a shell-and-power lease with a tenant bringing its own hardware. It is a full compute contract in which Nscale finances, procures and operates the Nvidia systems and sells the output as a service.

That distinction determines who carries which risk. Nscale takes on GPU procurement, depreciation and utilisation risk against a fixed-term revenue commitment; Anthropic converts an enormous capital requirement into an operating expense and secures silicon it does not have to buy outright. For a pre-IPO company, a single counterparty representing roughly $7.5 billion of annual contracted revenue is both the strongest item in the equity story and its most concentrated exposure.

Together with Microsoft’s 1.35GW, the reported Anthropic commitment would spoken-for roughly 1.8GW of a 2GW first phase before that phase is energised. Campuses of this scale used to be built on speculation and leased in slices. Monarch is being contracted forward, in bulk, by two of the largest buyers of AI compute in the market — which is exactly what a developer needs before it asks public markets for capital.

What $45 Billion Actually Buys

Run the arithmetic on the reported terms and the structure becomes visible. Four hundred sixty megawatts over seventy-two months is about 33.1 million kilowatt-months; $45 billion across that base is roughly $1,360 per kilowatt-month. Wholesale colocation — where a tenant rents powered, cooled space and installs its own servers — is quoted in the low hundreds of dollars per kilowatt-month in tight markets. An order-of-magnitude premium is not a landlord’s rent. It is the cost of the accelerators, the networking, the operations and the financing rolled into a per-unit price.

That matters for how readers should interpret the growing list of billion-dollar “capacity” announcements across this sector, because the same word covers very different products. A lease transfers space and power. A compute contract transfers a working cluster. The second carries far more revenue per megawatt and far more risk per megawatt: the provider is exposed to Nvidia’s delivery schedule, to the residual value of hardware whose successor generation is already on the roadmap, and to whether the customer’s demand persists past the contract’s early years.

Anthropic’s side of the trade is the mirror image. Rather than raising capital to buy Vera Rubin systems and finding somewhere to put them, it buys the finished output on a six-year term and keeps the balance sheet clean. The reported willingness of Google to provide a financial guarantee for Anthropic’s lease payments — an arrangement said to mirror one Google already has with Fluidstack — is the same instinct applied to credit: a developer will build faster for a tenant whose obligations sit behind an investment-grade balance sheet.

A Campus Booked Before It Is Built

Microsoft’s 1.35GW plus Anthropic’s reported 460MW is 1.81GW against a first phase described as 2GW. Two customers would account for the overwhelming majority of phase one. For Nscale, that is a powerful de-risking of an enormous capital programme, and it is the kind of contracted backlog that makes an IPO narrative legible to institutional investors. It also concentrates the company’s fortunes in two counterparties, one of which is a private AI lab whose own revenue trajectory is not publicly reported.

There is a timing question embedded in the reported details. The Anthropic chips are expected online in late 2027, while the 2GW first phase has been described as arriving in the first half of 2028. Those are reconcilable — large campuses energise in blocks, and the first buildings routinely come up well before a phase is declared complete — but the sequence has not been laid out. Which buildings serve which tenant, and in what order, is the difference between a customer training models in 2027 and one waiting on a substation.

The broader market context is that anchor-tenant pre-leasing has become the entry ticket for AI campus development. Speculative capacity still gets built, but the projects attracting debt at reasonable cost are the ones with signed offtake. That dynamic favours developers with access to the handful of buyers writing multi-gigawatt cheques, and it pushes smaller operators toward either niche positions or acquisition.

Gas Engines Instead of the Grid Queue

Monarch’s stated power strategy is Caterpillar G3500-series fast-response natural gas generator sets. In plain terms: reciprocating engines burning natural gas on site, generating electricity directly for the campus rather than drawing it from the regional transmission network. The engineering appeal is speed. Connecting a large load to the grid requires an interconnection study and queue position — a regulated process that in much of the United States now runs for years — and building the transmission to serve it can take longer still. Generating behind the meter sidesteps that clock almost entirely.

The trade-offs are real and mostly regulatory rather than technical. Gigawatt-scale on-site generation needs firm gas supply and pipeline capacity, air permits sized to the emissions of hundreds of engines, and a plan for what happens when gas prices move. West Virginia sits on Appalachian production, which is precisely why the site is there, but proximity to gas is not the same as contracted deliverability to a specific meter. None of those arrangements has been detailed publicly.

For the industry, this is the clearest expression yet of a structural shift: AI developers are no longer waiting for utilities. Behind-the-meter generation converts a permitting-and-queue problem into a fuel-and-emissions problem, which developers can solve on their own schedule. Whether regulators and neighbouring ratepayers see it the same way is the open question, and it is likely to be litigated campus by campus rather than settled nationally.

Financing the Backlog

Nscale’s reported IPO ambition of roughly $3 billion is small relative to the capital a 2GW first phase implies, which is normal — public equity is one tranche in a stack that typically includes project debt, vendor financing and, increasingly, customer prepayments. The signed backlog is what makes the rest of that stack available. It is also why the sequencing of announcement and offering deserves attention from investors: contracted revenue disclosed ahead of a listing sets the valuation frame, and terms such as take-or-pay minimums, termination rights and price escalators determine how much of a headline figure is genuinely committed.

Comparable operators are showing what the funding path looks like once public. Nebius Group told the market on August 24, 2026, in a press release furnished to the SEC as an exhibit to a Form 6-K, that it had closed $5.75 billion of convertible senior notes in two series — $3.45 billion of 0.50% notes due 2030 and $2.3 billion of 4.50% notes due 2034 — with proceeds earmarked for data center construction, footprint expansion and GPU procurement. Two days later, Nebius disclosed that its annual general meeting had approved authority for the board to issue Class A shares up to an additional 20% of issued share capital and to exclude pre-emptive rights, keeping equity headroom open alongside the debt.

The pattern is consistent across the neocloud category: long-dated contracted revenue on one side, convertible and structured debt on the other, and a persistent gap between the two that gets filled with equity. It works while contracts are signed faster than capacity is delivered. The risk is symmetrical and well understood — hardware depreciates on a schedule set by Nvidia’s product cadence, while the debt amortises on a schedule set by lenders, and a customer that slows its buildout leaves the provider holding both.

Background

Over the past two years a category of specialist providers — neoclouds — has grown up between chipmakers and AI developers. Companies such as Nscale, CoreWeave, Fluidstack and Nebius buy Nvidia accelerators in volume, build the power and cooling to run them, and sell the resulting capacity on multi-year contracts. The model is capital-intensive and contract-driven: signed offtake unlocks financing, financing buys hardware, and hardware depreciates on a schedule set by how quickly the next GPU generation arrives.

Anthropic, the developer of the Claude models, has been among the most aggressive buyers in that market, committing to more than 10GW of rented server capacity across providers including Google, Amazon Web Services, CoreWeave, Akamai and Fluidstack, and reportedly signing more than a dozen letters of intent for data center leases with US developers. West Virginia has become an attractive location for this build-out for a specific reason: proximity to Appalachian natural gas makes large behind-the-meter generation practical, letting developers bypass the multi-year grid interconnection queues that constrain siting elsewhere.
