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

May 27, 2026

May 28 (Reuters) – 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.
