Feb 3 (Reuters) - Elon Musk said on Monday SpaceX has acquired his artificial intelligence startup xAI in a record-setting deal, unifying the billionaire's AI and space ambitions by combining the rocket-and-satellite company with the maker of the Grok chatbot.

The deal brings together two of the largest closely held companies in the world. XAI raised funds at a $230 billion valuation in January, while SpaceX was set to go ahead with a share sale in December at a valuation of about $800 billion, Bloomberg reported.

A federal judge signaled she may dismiss a ‍lawsuit by Elon Musk's ‍startup xAI ‍accusing Sam Altman's rival OpenAI of stealing trade secrets.
