Nov 5 (Reuters) – Microsoft has rejected an option to more than double the size of its ​existing agreement with Nscale to ‌rent computing power at a Texas data center, walking away from a potential deal worth tens of billions of dollars, ‌the ​Financial Times reported ⁠on Thursday, citing ⁠people familiar with the matter.

Here’s what to know:

• The report comes weeks after Microsoft pulled out of a ​deal to anchor Nscale’s flagship data centre project in Loughton, Essex, ⁠after power connection ⁠delays pushed its expected supply ​date into the 2030s

• Reuters could ​not immediately verify the report

• Microsoft ‌and Nscale did not immediately respond to requests for comment outside business hours

• Nvidia-backed Nscale filed ⁠for a US initial public offering in September, with Microsoft and Anthropic expected to ⁠be ‌among its major customers

• ⁠Reuters reported last month Nscale ​was ‌in talks to sell ​AI computing ⁠power to Claude-maker Anthropic in a new deal that could be worth about $45 billion
