In February 2026, SpaceX bought xAI for $250 billion, the largest acquisition in corporate history. By mid-May, all 11 original xAI co-founders had left, and more than 50 SpaceXAI researchers and engineers had departed for Meta and Thinking Machines Lab. SpaceX's prospectus, published around May 15, confirmed the cost: a $4.94 billion net loss on $18.67 billion in 2025 revenue, driven by $14 billion in AI infrastructure spending.
SpaceX's IPO roadshow now targets a June 4 start, with pricing on June 11 and Nasdaq trading under ticker SPCX on June 12. The target valuation has grown to $1.75 trillion to $2 trillion. The prospectus confirmed Musk controls 79% of votes with about 42% of equity, through a dual-class structure: only he can vote himself out as CEO.
Why it matters
A $2 trillion listing would make SpaceX the most expensive company ever to trade publicly—and public investors would absorb its AI division's losses.
SpaceX is targeting a valuation between $1.75 trillion and $2 trillion for its June 2026 IPO, up from the $1.25 trillion combined value when the xAI acquisition closed in February

Fictional AI pastiche — not real quote.
"I observe Mr. Musk has discovered the most elegant solution to raising capital: selling one pocket to the other, then inviting the public to buy shares in the trousers. It is a comfort to know that in our modern age of electric wonder, a man may still achieve immortality through the ancient and respectable art of spectacular bookkeeping."

Fictional AI pastiche — not real quote.
"Consolidation of capital under singular vision has its merits, though I observe Mr. Musk acquires his own enterprise at a valuation that would make even the most creative financier of my era blush. One wonders whether orbital data centers represent productive investment or merely the costliest method yet devised to cool machinery—the vacuum of space being rather expensive real estate compared to a Pennsylvania riverside."

Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
1 of 3
November 1999 - February 2000
Vodafone-Mannesmann (2000)
British mobile operator Vodafone acquired German industrial conglomerate Mannesmann for $203 billion after a hostile takeover battle, creating the world's largest mobile telecommunications company. The deal involved Vodafone CEO Chris Gent convincing Mannesmann shareholders to accept an all-stock offer during the dot-com boom.
Then
Vodafone became the world's largest mobile operator with 42 million subscribers across 25 countries.
Now
The deal held the record for largest acquisition for 26 years until the SpaceX-xAI merger. Vodafone wrote down over $50 billion in value from the acquisition by 2006 as the telecom bubble burst.
Why this matters now
The previous record-holder demonstrates both the risks of all-stock mega-mergers during market exuberance and how quickly valuations can deteriorate when underlying assumptions prove wrong.
2 of 3
January 2000 - June 2009
AOL-Time Warner (2000)
America Online merged with Time Warner for $182 billion, promising to combine AOL's internet dominance with Time Warner's content empire. AOL's market capitalization at the time exceeded Time Warner's despite generating a fraction of the revenue.
Then
The dot-com bubble burst months after the deal closed. By 2002, the combined company reported a $99 billion loss—one of the largest in corporate history.
Now
Time Warner fully divested AOL in 2009. The merger became a cautionary tale about cultural clashes, overvaluation, and betting on technology shifts (dial-up to broadband) that undermined the acquirer's core business.
Why this matters now
The SpaceX-xAI merger similarly combines a profitable infrastructure business with a fast-growing but cash-burning technology company, raising questions about whether orbital data centers represent the future or an AOL-style bet on technology that may not materialize.

December 2019
Saudi Aramco IPO (2019)
Saudi Arabian Oil Company (Aramco) sold 1.5% of its shares on the Riyadh stock exchange, raising $25.6 billion at a $1.7 trillion valuation—the largest IPO in history. Crown Prince Mohammed bin Salman had originally targeted a $100 billion raise at $2 trillion valuation.
Then
Aramco's market cap briefly reached $2 trillion on its second trading day. The listing supported Saudi Arabia's Vision 2030 economic diversification plan.
Now
The IPO raised less than half the original target due to valuation skepticism from international investors. Aramco remained primarily held by the Saudi government and domestic investors.
Why this matters now
SpaceX's targeted $50 billion IPO would nearly double Aramco's record. The Aramco experience shows that even well-capitalized companies with dominant market positions can struggle to achieve aspirational valuations when international investors scrutinize the deal.
