Anthropic's $45B Compute Deal Is Unconfirmed, With Power In Late 2027

Reporting on 26 August at 17:35 UTC put a $45bn, six-year compute agreement between Anthropic and Nscale into circulation, originating with Bloomberg. The capacity is around 460 megawatts at Nscale's flagship West Virginia campus. Four qualifications belong with the number.

Nobody has confirmed it

There is no press release from either company, no filing and no on-the-record statement. The figure exists because a news organisation reported it. That may well be accurate — Bloomberg's record on compute contracts is strong — but a deal that has not been announced by either party is a report, and the difference matters when the number is larger than most national infrastructure programmes.

What the common framing gets wrong

The headline reads as though $45bn of computing capacity has been bought. What has reportedly been agreed is a six-year commitment to capacity that comes online in late 2027. Nothing is delivered this year and nothing is delivered next year. The hardware named is Nvidia's Vera Rubin generation, which is not shipping yet either. Divided across six years the figure is roughly $7.5bn a year, and the first of those years has not started. Reporting it as present-tense spending overstates by the entire length of the build.

The timing relative to the IPO

Nscale is preparing a US initial public offering as soon as next month. It is going to market citing a contracted revenue backlog of $51bn against roughly $100m of revenue booked in a recent quarter. If the Anthropic agreement is real at $45bn, it constitutes the overwhelming majority of that backlog — meaning a single unconfirmed counterparty accounts for most of the forward revenue an IPO is being priced on. That is the fact an investor would want confirmed on the record, and it is exactly the fact that has not been.

Microsoft was there first

The most instructive detail is the site's history. Microsoft signed a letter of intent for the West Virginia location in March and walked away during the summer — which is how the site became available to Anthropic. A hyperscaler with more data-centre experience than almost anyone evaluated this campus and declined it. That does not mean the site is bad; siting decisions turn on portfolio timing, grid interconnection queues and power pricing as much as on the asset. But it establishes that a letter of intent on this campus has already converted to nothing once, which is worth holding alongside a reported figure of $45bn.
