SpaceX has made history just days after its record-breaking initial public offering, surging past tech giant Microsoft, to claim the position of the world’s fourth most valuable company by market capitalization.
The aerospace giant, trading under the ticker $SPCX on Nasdaq, saw its valuation climb above $2.9 trillion on Tuesday, briefly overtaking Microsoft’s roughly $2.93 trillion market cap and also surpassing Amazon.
This placed SpaceX behind only a handful of titans typically Nvidia, Apple, Alphabet, and occasionally other tech giants, depending on intraday moves.

A Meteoric Rise After IPO
SpaceX went public in mid-June 2026 in what became the largest IPO in history, raising approximately $85.7 billion. Shares priced at $135 debuted strongly, closing the first day around $161 and continuing to climb with double-digit gains in subsequent sessions.
In the following days, the stock continued climbing, briefly sending SpaceX’s valuation near or above the $3 trillion mark and positioning it among the world’s most valuable public companies, ahead of Amazon and Microsoft at peaks.
The stock has been fueled by intense investor enthusiasm, options trading frenzy, and optimism around the company’s core businesses.
Notably, SpaceX’s rapid ascent has captured widespread attention. On Polymarket, traders are pricing in roughly 52% odds that SpaceX ($SPCX) reaches a $3 trillion market cap by June 30, 2026, reflecting strong bullish sentiment around the company’s growth trajectory.
This comes after founder and CEO Elon Musk set an extraordinarily ambitious target, stating that the rocket company could generate roughly $1 trillion in annual revenue by 2030.
Also, Musk’s stake in SpaceX, has propelled his personal net worth significantly, with reports noting him briefly becoming the world’s first trillionaire amid the post-IPO rally.
At the heart of the surge is Starlink, SpaceX’s satellite internet constellation, which continues rapid global expansion and revenue growth.
The company also benefits from its leadership in reusable rocket technology, with the Starship program advancing toward operational flights that could transform satellite deployment, space tourism, and future Mars missions.
Earlier this year, SpaceX merged with Elon Musk’s xAI, further blending its space ambitions with artificial intelligence capabilities.
What This Means for the Market
Reaching near $3 trillion in market value so quickly underscores the market’s massive bet on SpaceX’s long-term potential.
The company reported about $18.7 billion in revenue for 2025, but investors are clearly pricing in explosive future growth from Starlink subscribers, government contracts, and new frontiers in space infrastructure.
Whether it sustains this pace and hits the $3 trillion threshold in the near term remains to be seen, but the company’s trajectory has already rewritten expectations for what a space-focused public company can achieve.
However, the rapid ascent has also drawn comparisons to meme-stock volatility. Some analysts question whether the lofty valuation—trading at a very high multiple to current revenue—is sustainable, especially as the company has reported losses in recent years.
Looking Ahead
SpaceX now sits among the elite of global corporations, a remarkable feat for a company that was private for over two decades. The coming months will test whether it can maintain this momentum through execution on Starship, Starlink profitability, and new revenue streams.
For now, SpaceX continues to capture the imagination of investors and the public alike, embodying both the risks and rewards of betting on humanity’s expansion into space.
