05:46 AM EDT, 05/28/2026 (MT Newswires) -- SpaceX (SPCX) has agreed to lease its Colossus artificial intelligence training data center clusters to Amazon ( AMZN )-backed (AMZN) Anthropic for only 180 days, SpaceX Chief Executive Elon Musk said in a Thursday post on social media platform X.

"The short term was our request, not Anthropic's," Musk said, adding that the deal comes with a 90-day notice for mutual cancellation.

"We won't leave them hanging and will provide a reasonable off-ramp, but if compute gets super tight I said we might need it back at some point," Musk said.

Anthropic did not immediately respond to MT Newswires' request for a comment.
