Key Takeaways:
SpaceX's $75 billion IPO — the largest in history — sent SPCX shares up 19% on their first trading day Friday, pushing the rocket maker's market capitalization past $2 trillion and minting Elon Musk the world's first trillionaire.
"The stock's strong opening reflects genuine market enthusiasm for the company's technological leadership and Starlink's growing recurring revenue," said Mike Alves, managing partner at VIDA Vision Fund, which held SpaceX in its private portfolio. "At current trading levels, however, the valuation appears stretched relative to near-term profitability."
The company offered 555,555,555 shares at $135 each, raising $75 billion in primary capital. SPCX opened at $150, an 11% premium, climbed to an intraday high of $176.52, and closed at $160.95. More than 500 million shares changed hands during the session, approaching the volume Facebook recorded in its 2012 debut. The offering triggered a rotation out of large-cap technology stocks, with the Roundhill Magnificent Seven ETF falling 2.4% as hedge funds trimmed positions in Apple and other mega-caps to free up capital, according to JPMorgan data.
The IPO transforms SpaceX from a privately held aerospace contractor into a publicly traded conglomerate spanning rocket manufacturing, satellite internet, artificial intelligence and social media — following its February acquisition of xAI. With accumulated losses of $41.3 billion since 2002 and only Starlink generating consistent profit, the company's $28.5 trillion total addressable market estimate — which valuation expert Aswath Damodaran called a hallucination — assumes near-perfect execution across multiple unproven initiatives.
Starlink Remains the Profit Engine
SpaceX's only consistently profitable segment is Starlink, the satellite internet constellation that has grown to millions of subscribers globally. During pre-IPO marketing, Musk disclosed that SpaceX has been cash-flow positive since around 2015, a milestone achieved primarily through Starlink's subscriber growth and improving unit economics. The division's recurring revenue model provides a stable foundation against the losses generated by the launch services business.
The February 2026 acquisition of xAI brought together data center infrastructure, Grok AI models and the social network X under a single corporate umbrella. Musk has outlined plans to deploy artificial intelligence data centers in orbit, a project that would require the orbital payload capacity he recently claimed could reach 1 million tons within five years.
Hedge Fund Rotation and Market Implications
In the days before the debut, hedge funds executed substantial selling campaigns across the largest U.S. technology stocks to free up capital, according to JPMorgan. Some funds established bearish positions through short sales and put options. The rotation pattern illustrates how even mega-cap technology stocks can face sudden liquidity-driven selling when sufficiently attractive alternatives emerge.
The success of SpaceX's public debut may encourage other high-profile private companies to accelerate their listing timelines. Robert Greifeld, former chief of the Nasdaq, predicted that OpenAI and Anthropic would likely go public this year following SpaceX's successful window-opening.
For investors, the key question is whether SpaceX's current valuation adequately reflects the risks and timeline required to realize its vision. If Starlink continues expanding profitably and the company demonstrates progress toward its orbital infrastructure goals, the $2 trillion market capitalization may eventually appear justified. If execution falters, the downside from current levels could be significant.
