Elon Musk says SpaceX did not commit to long-term Colossus lease with Anthropic

SpaceX CEO Elon Musk said on Thursday the IPO-bound company had only agreed to lease its Colossus AI training ‌data ⁠center ⁠clusters to Anthropic for six months, not multiple years as previously suggested.

"SpaceX has not committed to leasing Colossus for years, although it's ⁠possible that ‌may be what happens," Musk said in ⁠a post on X.

He added that the agreement is a 180-day lease with a mutual 90-day cancellation notice thereafter.


"The short term was our request, ‌not Anthropic's. 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," he said.
