What happened

Microsoft has pulled out of a planned UK data center project run by Nscale after the grid operator warned that power may not arrive until the 2030s. Nscale is also negotiating a large computing deal with Anthropic, and its latest filing confirms a $44.6 billion agreement with the AI lab.
