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, though he added it was "possible" ⁠the arrangement could extend for multiple years.

"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.

Earlier this year, SpaceX inked deals for ​Anthropic to pay it $1.25 billion a month to use compute capacity from its Colossus and Colossus II data center clusters ⁠in Memphis, Tennessee through May 2029.

SpaceX, which filed for IPO last week, said in ​the regulatory filing that both companies could terminate the agreements with a 90-day notice. The filing did ​not make any mention of the ‌six-month lease.

SpaceX and Anthropic did not immediately respond to a Reuters request for comment outside regular ⁠business hours.

The agreement is a 180-day lease with a mutual 90-day cancellation notice thereafter, Musk said.

"The short term was our request, not Anthropic's," ⁠he said on X, referring to the Colossus deal.

"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," the ‌billionaire added.

Last week, Musk posted on X that SpaceX was in discussions with other companies about "offering ‌AI compute as a service at significant scale."

SpaceX's AI segment lost ⁠about $2.5 billion from operations in ‌the March quarter, ​on segment revenue of $818 million, according to its IPO filing.
