Anthropic is in talks for a second $45 billion, 460-megawatt lease at Nscale's Monarch Compute Campus in Mason County, West Virginia — potentially reaching 920 megawatts total at one site. The first deal was signed in August 2026, but Nscale's own IPO filings admitted financing and chip supply were not yet secured.

As of October 20–21, 2026, Anthropic is reportedly in talks with U.K.-based neocloud provider Nscale for a second computing-capacity agreement, potentially valued at approximately $45 billion.

About this episode

In August 2026, Anthropic signed a $45 billion, six-year deal with Nscale — a U.K.-based neocloud founded in 2024 — to lease 460 megawatts of AI compute at the Monarch Compute Campus in Mason County, West Virginia. By October 20, 2026, they were reportedly in talks to do it again: a second $45 billion agreement, a second 460-megawatt building, same site. That's 920 megawatts total, with a right of first refusal on a potential third building that would push the campus toward 1.35 gigawatts. This episode works through what's actually going on — and why the numbers are only half the story. The more revealing detail is in Nscale's own IPO filings, which disclosed that when the first deal was signed, the company hadn't locked in binding financing or all the chip supply needed to deliver it. That's not buried in the back. That's the company saying, on the record, we signed and we're still figuring out how to pay for it. But the episode doesn't treat that as a scandal — it treats it as a window into how infrastructure gets built under genuine scarcity. When the alternative is a site going to someone else or sitting empty for years, a flawed supplier with the right land and Nvidia's backing looks different than it would in a normal market. Late 2027 is the date to watch: that's when Vera Rubin chips are supposed to be running in the first Monarch building. Everything else is contingent on that one delivery milestone.

Frequently asked

What is Anthropic's data center deal with Nscale in West Virginia?

Anthropic signed a $45 billion, six-year lease for 460 megawatts at Nscale's Monarch Compute Campus in Mason County, West Virginia in August 2026. As of October 20, 2026, Anthropic is in talks for a second identical deal at the same site, which would bring total capacity to 920 megawatts.

Is Nscale financially stable enough to build the Monarch Compute Campus?

Nscale's own IPO filings stated that, when the first $45 billion Anthropic deal was signed, Nscale had not secured binding financing or all required chip supply to fund the buildout. Founded in 2024 and valued at $14.6 billion after a $2 billion raise in March 2026, the company has Nvidia as a backer but carries real delivery risk.

When will Anthropic's compute at the Monarch Compute Campus come online?

Compute from the first Monarch Compute Campus building — 460 megawatts powered by Nvidia Vera Rubin chips — is expected to come online in late 2027. That delivery milestone is the critical test for the entire Anthropic-Nscale partnership; the second unsigned deal and any further expansion are contingent on it.

Why is Anthropic signing so many data center deals across different vendors?

Anthropic has committed to infrastructure partnerships totaling over $518 billion, spanning AWS, Google, Broadcom, SpaceX's Colossus 1, Riot Platforms, and Nscale. The diversification reflects uncertainty about which vendors will deliver on time, not confidence in any single one — Anthropic is effectively signing with every viable compute source simultaneously.

What is a neocloud company and how does Nscale fit that description?

A neocloud is an AI-focused infrastructure company that leases GPU compute for AI workloads, distinct from hyperscalers like AWS or Google Cloud. Nscale, founded in 2024 and backed by Nvidia, fits this model — it builds and operates large-scale GPU data centers specifically for AI training and inference workloads.

Finn Brooks: Mason County, West Virginia.

Finn Brooks: Remember that name.

Finn Brooks: Because right now there is a data center campus going up there — the Monarch Compute Campus — and Anthropic, the AI lab behind Claude, is in talks to put forty-five billion dollars into it. For the second time.

Finn Brooks: Second time.

Finn Brooks: First deal was August 2026 — forty-five billion, six years, 460 megawatts, Nvidia Vera Rubin chips, compute expected online late 2027.

Finn Brooks: And then — reported October 20, 2026 — they're apparently negotiating a second forty-five billion dollar agreement, for a second 460-megawatt building at the exact same site.

Finn Brooks: That's 920 megawatts total. Two mid-sized cities worth of electricity, pointed at one AI lab's models.

Finn Brooks: And the company building all of this — Nscale, U.K.-based, founded in 2024, backed by Nvidia — is what you'd call a neocloud.

Finn Brooks: Not AWS.

Finn Brooks: Not Google Cloud.

Finn Brooks: A neocloud is a newer kind of infrastructure company — AI-focused, leasing GPU compute for AI workloads, none of the decades of legacy baggage — and in Nscale's case, two years old when this deal was signed.

Finn Brooks: And here's what their own IPO filings actually say — as of the first Anthropic deal, Nscale had not secured binding financing to fund the buildout.

Finn Brooks: Had not secured all the chip supply either.

Finn Brooks: The contract has stringent delivery milestones and cancellation provisions — which, look, you don't write cancellation provisions into a ninety-billion-dollar deal because everything is going great.

Finn Brooks: And honestly, the cancellation provisions — that's the part that actually makes sense to me.

Finn Brooks: Because if you're Anthropic, you're not betting the whole company on Nscale delivering. You're buying an option. You're buying a slot in a world where permitted, powered land for AI data centers is — genuinely, not rhetorically — one of the scarcest things on earth right now.

Finn Brooks: Here's where Microsoft matters.

Finn Brooks: Microsoft announced a letter of intent on a West Virginia facility in March 2026. By summer 2026, they were gone. Withdrew. And when they left, that site — the one that becomes Monarch Compute Campus — came open.

Finn Brooks: Nscale stepped in. Anthropic followed.

Finn Brooks: That is not a coincidence, that is a gap being filled at speed. And the gap exists because finding a site with grid access, permits, physical space for something approaching 1.35 gigawatts — which is where Monarch is apparently headed, with Anthropic holding right of first refusal on a potential THIRD building — that does not happen casually.

Finn Brooks: So yeah, Nscale's own IPO filings say they hadn't locked in financing or all the chip supply when they signed the first deal. That's a real thing. But the alternative isn't some perfectly capitalized competitor with a cleaner balance sheet — the alternative is the site goes to someone else, or sits empty, or you wait two more years for the next one.

Finn Brooks: When land is the constraint, a flawed supplier becomes irreplaceable.

Finn Brooks: And Nscale isn't exactly a phantom — they raised two billion dollars at a fourteen-point-six billion dollar valuation in March 2026. They have Nvidia as a backer. The Vera Rubin chips — six chips working in concert, Nvidia's next-generation system — those are specified in the delivery timeline, compute expected late 2027.

Finn Brooks: That's the bet. Not that Nscale is flawless. That Nscale has the site, has Nvidia in its corner, and has enough runway to make delivery plausible.

Finn Brooks: And the hedge — the hedge isn't the cancellation clause. The hedge is everything else Anthropic is doing simultaneously.

Finn Brooks: AWS. Google and Broadcom. SpaceX renting out Colossus 1 capacity. And then Riot Platforms — a Bitcoin mining company, which is its own whole conversation — signing a twenty-year, one-hundred-ninety-one-megawatt, nine-point-one-billion-dollar data center lease with Anthropic. Twenty years. That is not a short-term hedge, that is a land-grab across every viable compute source on the planet.

Finn Brooks: Anthropic has publicly framed its long-term infrastructure commitment at over five hundred eighteen billion dollars across all of this. That number is almost hard to hold in your head.

Finn Brooks: The diversification isn't confidence in any single vendor — it's the opposite. It's what you do when you're not sure which of these actually delivers on time, so you sign all of them and let the cancellation provisions sort it out.

Finn Brooks: But none of that is settled yet. The second deal? Still in talks as of October 20, 2026. Not signed. That matters.

Finn Brooks: The number to hold onto is late 2027. That's when compute from the first Monarch building is supposed to come online — Nvidia Vera Rubin chips, first building, 460 megawatts. That delivery is the test. Not the paperwork. The actual hardware running.

Finn Brooks: If Nscale hits that — if Vera Rubin chips are online at Monarch Compute Campus, late 2027, on schedule — the whole strategy starts to look rational. The unsigned second deal looks like smart sequencing. The cancellation provisions look like discipline, not fear.

Finn Brooks: If it misses… every subsequent deal looks like compounding exposure. Including the one that isn't even signed yet.

Finn Brooks: And the thing is — Nscale is not just running one job right now. They announced a fourteen-billion-dollar expanded partnership with Microsoft. They've got a Stargate-branded data center they're building with OpenAI in Norway. And they're trying to close out financing and chip supply that their own IPO filings admitted wasn't locked in when they signed with Anthropic.

Finn Brooks: That's a lot of plates.

Finn Brooks: Governor Patrick Morrisey has publicly welcomed all of this — framed it as West Virginia's AI moment, which, I mean, I get the politics — but the welcome doesn't build the data center. Financing builds the data center. Nvidia delivering Vera Rubin chips on schedule builds the data center.

Finn Brooks: And look — SpaceX posted a more-than-ninefold rise in AI revenue last quarter, mostly from renting compute capacity to Anthropic, Google, Reflection AI. Ninefold. That tells you the demand is real, that Claude needs that compute, that Anthropic is actively pulling from every source it can find while Monarch gets built.

Finn Brooks: So what do you actually watch? Late 2027. Vera Rubin. First building. Does it ship? That's the signal. Everything else — the unsigned second forty-five billion, the right of first refusal on a THIRD building, the 1.35 gigawatt ceiling — all of it is contingent on that one delivery milestone holding.

Finn Brooks: All of it. Every Claude model running on infrastructure that doesn't exist yet. That's where we are.

Finn Brooks: And I keep landing back on this one detail and I can't let it go — Nscale was founded in 2024. That's it. That's the whole company's lifespan when Anthropic handed them the first forty-five billion. Two years old. And their own IPO filings said, in plain language, that they hadn't locked in the financing to actually build the thing they'd just promised to build. That is not a footnote buried in the back. That is the company telling you, on the record, we signed this contract and we are still figuring out how to pay for it.

Finn Brooks: Late 2027. That's the date. That's when Vera Rubin chips are supposed to be running inside that first Monarch building — and until that happens, until actual compute is online and Claude is running on it, everything else is paperwork signed by a company that was two years old when the ink dried.
