Microsoft Rejects Multibillion-Dollar AI Partnership Deal With UK's Nscale

Microsoft has turned down a major multibillion-dollar artificial intelligence partnership deal with Nscale, the British AI infrastructure company, according to a Financial Times report. The rejection represents a significant setback for Nscale, a UK-based firm that had been pursuing a large-scale commercial arrangement with one of the world's biggest technology companies.

The FT's report, confirmed across multiple newswire sources on November 5, 2026, did not detail the specific terms Microsoft found unacceptable, but characterized the deal as multibillion-dollar in scale. The move is seen as a blow to Nscale's ambitions and to Britain's broader efforts to attract major AI infrastructure investment.
