xAI, maker of Grok, was absorbed into SpaceX and now trades as part of Nasdaq-listed SPCX.
xAI built Grok, the assistant wired into the X platform, before SpaceX acquired it in an all-stock February deal that pegged the AI business near $250 billion. Musk then folded it fully into the rebranded SpaceXAI unit — which owns X, Grok, and the compute buildout — and the combined company went public on Nasdaq as SPCX in a record listing. Grok itself reached roughly 117 million monthly users, with revenue near a $500 million annualized rate early in the year.
