Microsoft rejects multibillion-dollar AI deal with UK’s Nscale, FT reports
Microsoft reportedly rejected a potential deal worth tens of billions with Nscale to expand computing power rental, according to the Financial Times. The deal would have more than doubled their existing agreement. Nscale, backed by Nvidia, filed for a US IPO in September and is in talks with Anthropic for another deal. Microsoft and Nscale did not comment. Reuters could not verify the report.
