Space Exploration Technologies Corp. Class A Common StockAltman criticizes SpaceX's space-based AI data center timeline as unrealistic, highlighting unresolved technical challenges.

OpenAI CEO Sam Altman has publicly challenged Elon Musk's claim that SpaceX will begin flying orbital AI data centers next year, arguing the timeline is unrealistic. Altman's criticism, posted on X, referenced SpaceX's IPO filing which envisions deploying massive AI compute satellite constellations for orbital data centers. While the technology exists, Altman points to unresolved challenges including launch reliability, high costs, repair difficulties, and limited wireless bandwidth. Musk responded by stating flights would start next year, but Altman maintains space-based AI data centers are not a viable option for at least several years.
