Elon Musk announced that SpaceX has acquired xAI in a $250 billion all-stock transaction, valuing the combined entity at $1.25 trillion. The merger aims to integrate SpaceX's space infrastructure with xAI's artificial intelligence capabilities, focusing on orbital data centers powered by solar energy. This move follows speculation about potential consolidations among Musk's companies and positions the firm for a possible initial public offering this year.
On February 2, 2026, Elon Musk revealed in a SpaceX blog post that the company had acquired xAI, his artificial intelligence venture, in a $250 billion all-stock deal. Prior to the announcement, betting markets had placed a 48% chance on a SpaceX-xAI merger by mid-year, compared to just 15% for a Tesla-SpaceX combination. The acquisition builds on xAI's purchase of Musk's social media platform X in March 2025, sparking questions about further integration across Musk's empire.
The merged entity, valued at $1.25 trillion with SpaceX at $1 trillion and xAI at $250 billion beforehand, seeks to create a vertically integrated system combining SpaceX's rockets, Starlink satellites, and direct-to-mobile communications with xAI's Grok chatbot and AI technologies. Musk envisions shifting AI computing to space, leveraging unlimited solar power without terrestrial constraints like grid limitations or cooling needs. Plans include deploying a million-satellite constellation for orbital data centers, starting with 100 gigawatts of AI compute and scaling to one terawatt annually. This infrastructure would support ambitions for lunar bases and Mars settlements.
Challenges remain significant. Space-based cooling depends on radiative methods alone, requiring heavy radiators, while cosmic radiation demands shielding and hardware replacements every five to six years. Launch costs, currently $2,000 to $2,500 per kilogram, must fall dramatically—Musk believes to achievable levels within two to three years via Starship's capabilities, potentially undercutting earthly AI compute costs.
Speculation persists about a Tesla merger, with analysts like Dan Ives noting a 'growing chance' due to synergies in AI autonomy and robotics. However, it could dilute Tesla shareholders and invite antitrust scrutiny over dominance in electric vehicles, space, satellites, and AI. The market responded positively, viewing the deal as innovative amid preparations for a SpaceX IPO that could exceed $1.5 trillion valuation and raise up to $50 billion, though regulatory concerns around satellite dominance and national security loom.
