Elon Musk merged SpaceX and xAI on February 2, creating a $1.25 trillion company. The deal combines a 24-year-old rocket manufacturer valued at $1 trillion with a 2.5-year-old artificial intelligence company valued at $250 billion. It is the largest merger in history. The previous record was Vodafone’s $203 billion acquisition of Mannesmann in 2000.
Nevada incorporation documents filed February 2 show a triangular merger structure. xAI becomes a wholly-owned subsidiary of SpaceX. Former xAI shareholders receive 0.1433 shares of SpaceX for each xAI share. The deal closed the same day documents were filed.
Musk told Bloomberg the merger creates synergy between rockets and artificial intelligence. SpaceX will launch orbital data centers using Starship. The AI servers will operate in space, avoiding terrestrial power grid constraints and cooling costs. xAI’s Grok chatbot requires massive computing infrastructure that ground-based facilities cannot efficiently provide.
The combined company exceeds the gross domestic product of France ($2.7 trillion in 2024) and approaches Japan ($4.2 trillion). Among corporate mergers, the previous largest was Vodafone-Mannesmann at $203 billion. The largest technology merger was Dell’s $67 billion acquisition of EMC in 2016. The SpaceX-xAI deal is six times larger than Vodafone-Mannesmann.
SpaceX has remained private since Musk founded it in 2002. The company operates Starlink satellite internet, manufactures Falcon 9 and Starship rockets, and holds NASA contracts for lunar missions. Private market valuations reached $1 trillion in late 2025.
xAI launched in July 2023. The company released Grok, a chatbot competing with OpenAI’s ChatGPT and Anthropic’s Claude. Private funding rounds valued xAI at $250 billion by January 2026. The company operates from Memphis, Tennessee, where it built a data center with 100,000 graphics processing units.
Musk announced plans for a mid-2026 initial public offering. Investment banks told CNBC the combined entity could command a $1.5 trillion valuation in public markets. That would make it the largest IPO in history. The current record is Saudi Aramco’s $29.4 billion offering in 2019.
The merger required no regulatory approval because both companies were privately held. The Federal Trade Commission has no jurisdiction over mergers between private companies that do not meet Hart-Scott-Rodino filing thresholds. SpaceX and xAI operate in different markets with no competitive overlap.
A private company built a rocket business for 24 years and an AI business for 2.5 years, then merged them into an entity valued larger than most nations. Public markets will determine in mid-2026 whether private valuations reflect economic reality or venture capital optimism.
