Microsoft Just Walked Away From a Huge AI Deal
Microsoft (MSFT) chose not to expand an AI computing deal with UK startup Nscale, forgoing a potential $43.8B agreement. The existing contract remains, but Nscale must find other customers for unused Texas capacity. Nscale's IPO, valued around $35B, faces increased scrutiny.
