SpaceX completed its acquisition of xAI in February 2026, valuing the AI company at $250 billion in an all-share deal that put the combined entity at $1.25 trillion, per CNBC. That transaction was the largest corporate merger on record, and it completed the consolidation of Elon Musk's AI assets under one roof. Here is a map of his four active fronts, as of June 2026.
xAI Absorbed Into SpaceX at a Record Valuation
One month before the merger closed, xAI completed a $20 billion Series E round at a $230 billion pre-money valuation from investors including Nvidia, Cisco, and Fidelity, according to CNBC. That put the company's implied value roughly ten times higher than the $24 billion it carried after its May 2024 Series B, which raised $6 billion, according to Bloomberg's coverage of that round. The pace of re-rating is unusual even for AI companies: xAI was founded in March 2023.
The SpaceX acquisition, announced February 2, 2026, was structured as an all-share exchange at a ratio of 0.1433 SpaceX shares per xAI share, per TechCrunch. Musk's stated rationale, in a public blog post, was that terrestrial data centers cannot meet global AI electricity demand at scale, but orbital data centers fed by Starlink's satellite constellation could. Grok, the Colossus supercomputer in Memphis, and the xAI API now operate as divisions of SpaceX. The combined xAI-plus-X segment generated $3.2 billion in revenue during 2025, up 22 percent year-on-year, against a $6.36 billion operating loss, per financial research platform Sacra. The Financial Times has reported that SpaceX is targeting a valuation as high as $1.5 trillion and a raise of up to $50 billion in its IPO, meaning xAI's revenue trajectory will be a central disclosure in that prospectus.
Earlier deals in the xAI infrastructure build-out are documented in StartupHub's coverage of xAI's $5.3 billion debt-and-equity round from 2025, which funded the initial Colossus cluster expansion.
Tesla Deploys Unsupervised Robotaxi in Dallas and Houston
Tesla launched unsupervised Robotaxi rides in Dallas and Houston in April 2026, expanding beyond the supervised beta it opened in Austin in June 2025, according to Tesla's first-quarter 2026 10-Q filing with the SEC. The Cybercab, a purpose-built autonomous vehicle without a steering wheel or pedals, is assembled at Tesla's Gigafactory in Texas. On the Q1 2026 earnings call, Musk said robotaxi revenue would "not be material" in 2026, with meaningful contribution expected in 2027. The statement was consistent with analyst consensus compiled by Visible Alpha, which projects Cybercab revenues at roughly $1 billion for 2026, less than two percent of Tesla's total automotive sales, per a recap published by HeyGoTrade.
