SpaceX shares dipped below their $135 IPO price on Wednesday afternoon, trading as low as $133 before recovering to hover around the offering level. The decline comes less than a month after the company’s blockbuster June 12 IPO, which raised nearly $86 billion.
The stock initially surged after the IPO, briefly reaching above $200 per share in the days following the listing. That rally gave SpaceX a valuation that briefly rivaled tech giants like Amazon and Microsoft. But the shares have lost value in each subsequent week.

Small float amplifies price swings
Market analysts point to an unusual structural factor behind the volatility: only about 4% of SpaceX’s total shares are trading on the Nasdaq. This small “float” means that even modest trading volumes can produce outsized price moves. Combined with intense media and investor attention on Elon Musk’s company, the stock has experienced wild swings during its first month as a public company.
The broader market environment has also turned less favorable for high-growth tech stocks over the past month. A broader deflation in tech valuations has compounded the pressure on SpaceX shares. Even bonds that the company sold shortly after the IPO are reportedly trading lower.

Starship test flight looms
SpaceX faces an immediate catalyst that could determine the stock’s near-term direction. On Thursday, the company plans to test launch its Starship rocket for the first time since going public. This will be the first Starship flight since a booster failure in May.
The company is not attempting to recover either the Starship booster or its upper stage on this flight. Both are expected to simulate a landing in the Gulf of Mexico, which means both components will be destroyed regardless of whether the flight plan proceeds without issues. The approach reflects SpaceX’s well-known “fly, fail, fix” development philosophy.
Starship remains in active development and has a track record of failures during testing. A successful flight — even one ending in planned explosions — could help restore confidence in the program. A failure during ascent, however, could add to negative sentiment around the stock.
Broader market implications
SpaceX’s IPO has set expectations for other high-profile tech companies considering going public. Both Anthropic and OpenAI have filed confidentially for IPOs, though neither has set a date. Investors and bankers are watching SpaceX’s trading performance closely as an indicator of market appetite for ambitious tech offerings.
The prolonged downturn in SpaceX shares could have wider effects because the stock price serves as a barometer for how the market views Musk’s ambitious promises about the company’s future capabilities. A sustained decline would raise questions about whether investors are beginning to discount those promises.
Frequently Asked Questions
Why did SpaceX stock fall below its IPO price?
The stock has declined steadily since peaking above $200 shortly after its June 12 IPO. Analysts attribute the drop to a small public float of just 4% of total shares, which creates volatility, and a broader cooling in tech stocks.
What is the significance of the upcoming Starship launch for SpaceX stock?
The Starship test flight is a major early test of investor confidence. A failure could pressure the stock further, while a successful flight — even with the planned explosions — may stabilize sentiment.
How much of SpaceX is publicly traded?
Only about 4% of SpaceX’s total shares are listed on the Nasdaq. This small float means that relatively modest trading volumes can cause large price swings.
Could SpaceX’s stock performance affect other tech IPOs?
Yes. Companies like Anthropic and OpenAI have filed confidentially for IPOs, and SpaceX’s trading performance is being watched as a bellwether for investor appetite for high-profile tech offerings.
