Anthropic may be about to sign a second $45 billion check to the same landlord. On Monday, Bloomberg reported that Nvidia-backed Nscale is in advanced talks to sell Anthropic another 460 megawatts of AI computing power — enough electricity to light up hundreds of thousands of homes — at its Monarch campus in West Virginia. If the deal closes, Anthropic’s committed compute spending with Nscale alone would approach $90 billion.
This is the Nscale Anthropic $45 billion deal everyone in AI infrastructure is watching: not because $45B is new — the first one was signed in August — but because Anthropic is doubling down weeks before its expected November IPO. Here’s what’s actually on the table, the red flags investors are whispering about, and what it means for your money.
What Bloomberg reported on Monday
According to Bloomberg News, citing people familiar with the negotiations, Nscale is in talks to sell Anthropic compute capacity in a second roughly $45 billion agreement covering another 460-megawatt building at the Monarch Compute Campus in Point Pleasant, West Virginia. The facility would run on Nvidia’s Vera Rubin accelerators, the next-generation chips Nscale is deploying across its fleet.
Key details, all from the reporting:
- Value: about $45 billion, mirroring the August deal.
- Capacity: 460 megawatts in a second Monarch building.
- Optionality: Anthropic reportedly holds a right of first refusal on an expected third building at the site.
- Status: talks are ongoing and terms could change. Nscale and Anthropic did not respond to Reuters’ requests for comment, and Reuters said it could not independently verify the report.
The first agreement, signed in August 2026, is a six-year, $45 billion, 460 MW lease at the same campus, with delivery slated to begin in late 2027. Nscale’s IPO filing puts existing Anthropic commitments at up to $44.6 billion.
The Monarch campus in numbers
Monarch is Nscale’s flagship bet: a 2,250-acre site in Mason County, West Virginia, acquired in March 2026, with a clear expansion path to 8 gigawatts and beyond, powered by an on-site microgrid using Caterpillar’s fast-response natural gas generator sets. Microsoft had originally been lined up for 1.35 GW of Vera Rubin capacity at the site before walking away from a separate UK project.

Why Anthropic keeps buying compute at this scale
Anthropic is racing to lock in capacity before its expected mid-November IPO. Claude Pro and Claude Max subscriber capacity is the stated beneficiary of the Monarch deal — Anthropic said the new data center capacity would directly improve service for paying subscribers. And on October 18, the company committed 5% of its shares to a new public benefit fund, a move widely read as IPO positioning.
The red flags investors are watching
$90 billion of forward commitments is a bet, not a bank balance. Here’s what could go wrong:
- Microsoft walked away. Microsoft pulled out of anchoring Nscale’s flagship UK data center in Loughton, Essex, after grid officials said power wouldn’t be available until the 2030s. Nscale says London-area grid constraints don’t affect other contracts — but power delays are the industry’s recurring nightmare.
- The IPO valuation is wobbling. Bloomberg reports investors are pushing back on Nscale’s roughly $30 billion IPO valuation target, with some telling bankers $16–19 billion would draw more buyers. Nscale’s Norway flagship is also running six months behind — 6.4 MW operational against a 30 MW target.
- Debt is spooking the market. Last week, Nscale rival CoreWeave’s shares slumped on concerns over its $50 billion debt load, fueling a global AI stock rout. Bloomberg also reports investors have urged Anthropic to lower its own IPO valuation target.
What this means for your money
The compute gold rush is creating a small set of very legible money trails. You don’t need to buy a data center to participate — but you do need to know where the leverage sits:
1 · Watch the NSCL IPO like a hawk
Nscale plans to list on the NYSE under ticker NSCL, aiming to raise up to $3 billion. Whether it prices near the $30B target or the $16–19B investors reportedly want will set the tone for every “neocloud” IPO after it. Read the S-1 risk factors before touching it — customer concentration is the whole story.
2 · Nvidia is the toll road
Both Monarch buildings run on Nvidia Vera Rubin systems. Every $45B lease is, indirectly, a giant Nvidia purchase order. If you want exposure to the AI buildout without betting on which lab wins, the picks-and-shovels trade remains the chip supplier and its supply chain.
3 · Track power, not just GPUs
The Microsoft/Loughton episode proves the bottleneck is electricity, not chips. Companies that can deliver behind-the-meter power — gas turbines, microgrids, grid interconnection — are the quiet winners. The CoreWeave rout is the warning: when $50B of leverage meets missed delivery dates, equities reprice fast. Treat neocloud stocks as cyclical infrastructure bets, not software margins.
Frequently asked questions
Is the second $45B Nscale–Anthropic deal confirmed?
No. Bloomberg reported on October 19, 2026 that the two are in talks for a second roughly $45 billion deal. The sources cautioned that talks are ongoing and terms could change. Neither company commented.
What did the first Nscale–Anthropic deal cover?
Signed in August 2026: a six-year, $45 billion lease for 460 MW of compute at Nscale’s Monarch campus in West Virginia, running on Nvidia Vera Rubin chips, with delivery beginning in late 2027.
When is Nscale’s IPO?
Nscale filed its S-1 registration statement on September 18, 2026, plans to list on the NYSE under ticker NSCL, and hopes to raise up to $3 billion. No pricing date has been announced; investors are reportedly pushing for a $16–19B valuation versus the company’s ~$30B target.
Why is Anthropic spending this much on compute?
To secure training and inference capacity for Claude ahead of its expected mid-November IPO, and to guarantee service quality for Claude Pro and Max subscribers as demand grows.
What are the biggest risks?
Power-delivery delays (as when Microsoft exited the UK Loughton project), Nscale’s IPO valuation dispute, investor scrutiny of debt-funded AI infrastructure after CoreWeave’s slump, and customer-concentration risk at the Monarch campus.
