TLDR
- SpaceX will begin trading on Nasdaq on June 12 under ticker SPCX at a ~$2 trillion valuation, the largest IPO in U.S. history
- Revenue growth slowed to 15% in Q1 2026, with an operating loss of $1.9 billion
- The IPO price-to-sales ratio of 103x is higher than any current S&P 500 stock; history suggests sharp declines follow
- S&P Dow Jones is consulting on rule changes that would let unprofitable mega-cap IPOs like SpaceX enter the index faster
- Around $20 trillion is benchmarked to the S&P 500, meaning passive funds could be forced to buy SpaceX shares automatically
SpaceX is set to go public on the Nasdaq on June 12 under the ticker SPCX, targeting a valuation of around $2 trillion. That would make it the largest IPO in U.S. history by initial market value.
SpaceX filed its amended IPO filing (S-1/A) today.
Here's everything new that I found:
• In relation to acquisitions, divestitures, or other strategic transactions, @SpaceX says they "may issue a significant amount of equity in connection with future transactions." 👀— Sawyer Merritt (@SawyerMerritt) June 1, 2026
The company filed its S-1 registration statement on May 20, after submitting confidential IPO paperwork to the SEC in April.
SpaceX’s Financials Tell a Mixed Story
SpaceX operates across three segments: space, connectivity, and AI. The connectivity segment, powered by its Starlink satellite internet service, currently brings in the most revenue.
In 2025, revenue grew 33% to $18.6 billion, slowing from 35% growth the year before. The company posted an operating loss of $4.9 billion that year.
In Q1 2026, revenue growth slowed further to 15%, and the operating loss widened to $1.9 billion. The company has been spending heavily on rockets and AI infrastructure.
One potential growth catalyst: in May, Anthropic agreed to pay SpaceX $1.25 billion per month for access to its Colossus supercomputers. The three-year deal could boost AI segment revenue in the second half of 2026.
SpaceX expanded into AI after acquiring xAI earlier this year. Its AI segment now offers cloud services, access to the Colossus supercomputers, and the Grok AI models.
A Valuation That Has Few Comparisons
SpaceX plans to go public at roughly 103 times sales. Palantir currently holds the highest valuation in the S&P 500 at 72 times sales. SpaceX would immediately be 40% more expensive than that.
A review of more than 100 technology stocks found only eight that ever traded above 100 times sales. All of them later dropped sharply, with declines ranging from 32% to 90% and an average drawdown of 75%.
History also shows that IPO stocks often jump on their first day — the average first-day gain has been 30% since 2020. But the 10 largest U.S. IPOs on record have underperformed the S&P 500 by an average of 127 percentage points since listing.
Index Rule Changes Could Force Passive Funds to Buy In
S&P Dow Jones Indices opened a consultation on April 30 about changing entry rules for large companies. The proposed changes would cut the seasoning period from 12 months to six, waive the profitability requirement for mega-caps, and potentially lower the float requirement.
Comments on the consultation closed May 28. If adopted, the changes take effect June 8 — four days before SpaceX starts trading.
SpaceX is expected to float only about 5% of its shares. That is a concern for index funds, which would be forced to buy shares of a $2 trillion company with very little stock actually available to trade.
Goldman Sachs analysts estimated that Nasdaq’s own fast-entry rule change could trigger up to $60 billion in forced buying across the Nasdaq-100 alone. The S&P 500 has far more tracking assets — roughly $20 trillion is indexed or benchmarked to it.
Corporate governance expert Nell Minow told Fortune the rule changes run counter to the purpose of an index. She predicted large institutional investors may push for alternative indexes that exclude these companies.
