Elon Musk clarified that SpaceX's lease of its Colossus AI training data center clusters to Anthropic is for six months, not multiple years as previously indicated. Musk stated on X that the short-term agreement was SpaceX's request, with a mutual 90-day cancellation notice possible thereafter. He added that SpaceX might reclaim the compute if it becomes critically scarce.

"As the recently expanded partnership with Anthropic demonstrates, SpaceX is offering AI compute as a service at significant scale"

SpaceX did not commit to a multi-year Colossus 1 lease with Anthropic, Elon Musk said on Wednesday, describing the agreement as 180 days with a 90-day mutual cancellation right.

SpaceX CEO says short-term deal could still be extended if capacity pressures ease
