SpaceX returns to $2T valuation after IPO volatility

SpaceX has clawed its way back to a $2 trillion market capitalization by early September 2026, roughly three months after its record-shattering debut on the Nasdaq.

The company went public on June 11 under the ticker SPCX, raising $75 billion by pricing shares at $135 each. That made it the largest IPO in US history, with an initial valuation of approximately $1.77 trillion across roughly 13.08 billion shares outstanding.

From liftoff to turbulence

SpaceX shares surged past the $2 trillion market cap threshold within the first trading days, briefly making Elon Musk the world’s first trillionaire on paper. Shares hit an intraday high near $226.

By late June, the stock had retreated to around $154, a drop of roughly 32% from peak values. The culprit was a painfully thin public float, with only about 4-5% of total shares actually available for trading.

The numbers behind the hype

SpaceX reported $18.7 billion in revenue for 2025, while posting a net loss of approximately $5 billion during the same period.

Morningstar analysts pegged SpaceX’s fair valuation at around $780 billion, which is less than half the company’s current market cap. SpaceX itself has framed its addressable market at $28.5 trillion, spanning launches, Starlink satellite internet services, and AI initiatives. Starlink has emerged as the company’s most profitable segment.

Musk retains an estimated 42-50% stake in the company, giving him concentrated voting control. That governance structure has drawn scrutiny from analysts who worry about the risks of a single individual wielding that much power over a $2 trillion public company.

Why the float matters more than fundamentals right now

The 4-5% public float is arguably the single most important number in SpaceX’s trading profile. For context, most large-cap stocks have public floats representing the vast majority of their outstanding shares. Apple’s float is essentially 100% of its shares. Even companies with significant insider ownership, like Meta, have floats well above 80%.

SpaceX’s float means the stock can move dramatically on relatively modest trading volume. Institutional investors who need to build large positions will struggle with liquidity, and the stock price functions as an unreliable signal for the company’s actual health.

The $75 billion raised in the IPO was a massive capital injection, but the $5 billion net loss in 2025 suggests the company is still firmly in investment mode. Scaling Starlink to global coverage, developing Starship for interplanetary missions, and expanding into AI-adjacent infrastructure all require enormous ongoing capital expenditure.
