SpaceX just pulled off the biggest IPO in history. And it wasn’t even close.

The aerospace company priced its shares at $135 on June 11, 2026, raising $75 billion in a single offering. By the time the closing bell rang on June 12, shares of SPCX on the Nasdaq had climbed to roughly $161, a 19% pop from the IPO price. That first-day surge pushed SpaceX’s market capitalization past $2.1 trillion, making it one of the most valuable public companies on the planet overnight.

More importantly for the history books: Elon Musk’s estimated net worth hit $1.1 trillion, making him the first person to ever cross that threshold. His SpaceX stake alone is now valued at around $690 billion.

Inside the numbers

To appreciate just how massive this IPO is, consider the context. The previous record for a public debut belonged to Saudi Aramco, which raised $25.6 billion back in 2019. SpaceX nearly tripled that figure.

The stock opened at approximately $150, an 11% premium to the IPO price, before climbing steadily throughout the session.

The market had already been telegraphing this kind of demand. Pre-IPO secondary trading earlier in 2026 had valued SpaceX as high as $1.7 trillion. By the time the company confidentially filed with the SEC in April 2026, institutional appetite was already through the roof. The actual listing simply confirmed what private markets had been pricing in, and then added another $400 billion on top.

Two decades in the making

SpaceX has been operational since 2002, meaning it spent over two decades as a private company. During those 24 years, the company fundamentally rewired the economics of space travel. Reusable rocket technology became routine. The Starlink satellite internet constellation grew into a global communications network. By late 2025, SpaceX’s private valuation had already reached $800 billion.

SpaceX’s journey from an $800 billion private valuation in late 2025 to a $1.7 trillion secondary market valuation in early 2026 to a $2.1 trillion public market cap represents a staggering acceleration. The company more than doubled in implied value in roughly six months.

What this means for investors

The immediate question for public market investors is whether SpaceX at $2.1 trillion represents an opportunity or a top. A 19% first-day gain is exciting if you got in at the IPO price. It’s considerably less exciting if you’re buying at $161.

There’s also the concentration risk around Musk himself. With a single individual now worth $1.1 trillion, a significant portion of that wealth is tied to one company’s stock price.

The crypto angle is notable mostly for its absence. Despite the current wave of enthusiasm around digital assets, SpaceX’s record-shattering debut was a purely traditional equity event. No tokens, no blockchain integration, no Web3 partnerships mentioned anywhere in the offering.
