Nscale's IPO filing, submitted Sept. 21, discloses a $44.6 billion agreement signed in August to supply Anthropic computing power through 2033, with financing for the deal not yet secured.[^3]

The filing lays out how concentrated the British data center developer's business is: Microsoft and Anthropic account for 85% of its $103 billion total contract value.[^2]

Nvidia sits on the other side of the cap table. The filing identifies Nvidia as a major shareholder and Nscale's primary chip supplier, and says Nvidia has acted as a backstop for roughly $860 million in lease obligations.[^1] Nvidia also participated in Nscale's $3.1 billion financing package, taking $1 billion in convertible notes or non-voting shares.[^4]

A signed contract that still needs financing is a roadmap, not a done deal. The filing's open question is where the money for the $44.6 billion Anthropic agreement comes from.
