SpaceX has lost nearly $1 trillion in market value since its June IPO, the largest post-listing wipeout in history, and the stock is still falling

SpaceX's $1 Trillion Repricing

SpaceX went public on June 12 at a record $1.75 trillion valuation, with shares priced at $135 1. The stock peaked four days later 1. What followed has been nearly unbroken decline.

Six straight sessions of selling have erased almost $1 trillion in market capitalization from that high, dropping the company's valuation to roughly $1.6 trillion 1. Shares continue to hit new lows as the sell-off shows no sign of reversing 2.

The declines are unfolding against a broader technology retreat that has dragged the sector lower 1. SpaceX is not alone in the red. But the scale of its loss far exceeds the general market pressure.

A $1.75 trillion valuation is not derived from trailing earnings or a proven revenue trajectory 3. It is a wager on a specific set of assumptions about future growth, market position, and execution risk. For SpaceX, those assumptions rest on satellite internet scale through Starlink, launch services revenue, and government contracts from NASA and the Pentagon. At the IPO price, investors were paying full value for all of those businesses maturing on schedule and compounding for years.

Six weeks in, the market is reexamining each pillar. A tech-wide sell-off gives institutional investors a reason to rotate capital out of their most expensive positions. When every bullish outcome is already reflected in the share price, ordinary macro headwinds produce outsized losses. The decline looks extreme because the entry valuation was extreme.

This is not unique to SpaceX. It is the pattern that high-profile IPOs follow when they list at premium valuations during periods of market optimism. Investors buy the narrative, the stock surges above the offering price, and then the realities of quarterly performance, competitive pressure, and macroeconomic shifts begin to erode the assumptions that justified the price. The unwind can be swift because the premium was never grounded in current financials.

The deeper risk is that IPO price targets are built from the most optimistic growth models the underwriting side can defend. They are designed to support demand for the offering, not to survive the first weeks of public-market scrutiny. The market reprices against the assumptions baked into them, and the gap between the IPO narrative and the balance sheet narrows on its own schedule.

The contagion from the broader tech sell-off compounds all of it. When investors are derisking across the sector, the highest-valuation names absorb the heaviest selling. SpaceX sits at the extreme end of that distribution. Its valuation at listing implied years of uninterrupted growth across multiple business lines. A sector-wide retreat tests that assumption on every front at once.

None of this is a judgment on SpaceX's operations. The company still launches rockets, operates the Starlink satellite network, and holds federal contracts 3. The narrower question the market is working through: were those operations worth $1.75 trillion on June 12? At $1.6 trillion and declining, the answer is trending toward no.

If the sell-off extends, SpaceX becomes a case study in how quickly an IPO premium gets repriced when the assumptions behind it meet public-market friction.
