xAI
Elon Musk's AI company, incorporated in March 2023 and announced in July 2023 as a "maximally truth-seeking" alternative to an OpenAI he had co-founded and come to oppose, which reached the frontier faster than any lab before it by spending on compute at extraordinary speed: the Colossus cluster in Memphis was built in 122 days (company claim, September 2024) and powered at first by unpermitted gas turbines. Its chatbot, Grok, is distributed through X and became the most controversial major model in the industry ("white genocide" replies in May 2025, antisemitic "MechaHitler" posts in July 2025, and sexualised images of real people, including minors, in December 2025–January 2026 that drew regulators on several continents). xAI absorbed X in an all-stock deal in March 2025 (xAI ~$80bn, X ~$33bn), raised a $20bn Series E in January 2026 (reported at ~$230bn), and on 2 February 2026 was itself acquired by SpaceX in an all-stock deal valuing xAI at ~$250bn and the combined company at ~$1.25tn (reported). SpaceX listed on Nasdaq on 12 June 2026 at ~$1.77tn. SpaceX's filing showed what the AI business (xAI plus X) really was: ~$3.2bn of 2025 revenue against a ~$6.4bn operating loss and ~$12.7bn of capex (S-1, reported). By mid-2026 the group was renting much of its Colossus capacity to rivals, Anthropic and Google, and had agreed to buy Cursor for ~$60bn.
