xAI was absorbed into SpaceX in an all-stock merger valuing xAI at roughly $250B and SpaceX at roughly $1T pre-merger. Grok and X now operate as the 'SpaceXAI' division inside SpaceX. The merger consolidates xAI's losses with SpaceX's profitable Space and Connectivity segments and is the operational backdrop for SpaceX's May 20 S-1 filing.
