From soaring to the first dip: SpaceX's market value surpasses $2.5 trillion, how long can the valuation fairy tale last?

On June 17 local time in the United States, SpaceX (SPCX) ended its three-day streak of gains since going public, closing down 4.95% at $191.82 per share. Its total market capitalization fell back to $2.51 trillion. This was the first time the company—currently the world’s largest IPO—has had a down close since it listed on the Nasdaq on June 12. During the day, SpaceX’s share price briefly rose by 6%, then reversed and moved lower, with a maximum intraday decline of 7.33%.

Before that, SpaceX went public at an offering price of $135 per share, implying a valuation of $1.77 trillion. On its first day, it closed up 19.22% at $160.95, and its market cap surpassed $2.1 trillion. Over the next three trading days, it rose consecutively; the share price touched as high as $218, and at one point the cumulative gain exceeded 61%. From the surge to the first decline, four trading days marked the switch from “IPO myth” to “market reality.” What exactly does this first drop mean? Is it a temporary profit-taking pullback, or the beginning of a valuation reset?

How the hawkish rate environment ends the “star IPO premium”

SpaceX’s first decline is not an isolated event—it is happening amid a sharp shift in the macro interest-rate environment. On June 17, the US Federal Reserve kept the federal funds rate unchanged at 3.50%–3.75%, but the dot plot released a strong hawkish signal. Of the 18 officials, 9 expect at least one rate hike within the year, including 5 expecting two hikes and 1 expecting three. By the end of 2026, the interest-rate mid-point was raised significantly from 3.4% in March to 3.8%. At the press conference, Federal Reserve Chair Wosch announced that the forward guidance would be dropped, saying, “I can’t tell you what the next step will be.”

The impact of the hawkish dot plot flowed directly into risk assets. That day, all three major US stock indices closed lower: the Dow fell 0.98%, the Nasdaq fell 1.34%, and the S&P 500 fell 1.21%. Major tech stocks were all down: Meta fell 5.44%, Microsoft fell 3.79%, and Amazon fell 3.46%. SpaceX closed down 4.95%, becoming a typical example of the tech sector pullback.

The “star IPO premium” depends on an expansion of risk appetite under a low-interest-rate environment. When interest-rate expectations shift from “cutting” to “hiking,” the discount rate applied to high-valuation stocks rises accordingly, putting systemic pressure on valuation multiples. SpaceX’s 19% gain on its first trading day and its subsequent rise over the next three days were largely built on expectations of easy policy. The appearance of the hawkish dot plot directly undermined that valuation foundation.

Behind the $2.51 trillion market cap, what level are valuation multiples really at?

Based on the June 17 closing price of $191.82, SpaceX’s market cap is about $2.51 trillion. Even after a 4.95% decline, the stock is still up more than 42% versus its $135 IPO offering price.

The meaning of this valuation level needs to be examined in the context of financial fundamentals. SpaceX’s 2025 revenue is $18.7 billion, up 33% year over year. With a $2.51 trillion market cap, the price-to-sales (P/S) ratio is roughly 134x. By comparison, Apple’s P/S ratio is about 9x, while Microsoft’s is about 12x. In 2025, SpaceX is expected to have a net loss of $4.9 billion.

The valuation is supported by SpaceX’s narrative structure: the commercialization of reusable rockets, the global rollout of Starlink satellite internet, and the AI compute business following the integration of xAI in February 2026. SpaceX has recently secured major compute procurement agreements with Anthropic and Google, and the 2026 revenue outlook has been raised significantly as a result. Musk has said on social media that 2030 revenue could reach $1 trillion—far above Wall Street’s estimate of about $330 billion for 2030.

The core contradiction in valuation is this: SpaceX’s narrative ceiling is extremely high, yet the current market cap already prices in growth expectations for the coming years. Any disruptions—whether macro or fundamental—could trigger a valuation correction.

Implied volatility on options soars—what kind of volatility is the market pricing in?

SpaceX options began trading on June 16. On the first day, option trading volume exceeded 1.6 million contracts, far above the 364,000-contract record set by Meta when it went public in 2012, making it the single stock with the highest options trading volume on the first day in US stock history.

Even more noteworthy is the extreme level of implied volatility. The implied volatility of short-dated contracts surged to between 158% and 167%. As of the close on June 17, SpaceX’s options implied volatility was as high as 97.5%. This means the market is preparing for two-way volatility of about 97% for the SPCX share price over the next year. Even measured against the standards of mega IPOs, this level of movement looks extreme.

Implied volatility is a direct reflection of how the market prices future uncertainty. An implied volatility of 97.5% means options traders expect SpaceX’s share price to potentially double or halve within a year. This pricing reflects several layers of uncertainty: the degree of divergence between valuation and fundamentals, the impact of chip-supply shocks after the lock-up period ends, and the ongoing suppression of high-valuation stocks by the macro interest-rate environment.

Volatility itself is also reflexive. Higher implied volatility means higher hedging costs, which in turn can suppress institutional investors’ willingness to build positions—further amplifying price swings.

Extremely low float and phased lock-up releases—how does the share structure affect the price path?

SpaceX’s initial price action was shaped largely by an extreme supply-and-demand structure. On the first day, the float was only about 4.2%, and Elon Musk’s personal holding of 640 million shares had a 366-day lock-up period. For a company with a market value of more than $2.6 trillion, the tradable float available in the early stage of listing was only about $100 billion. This scarcity—boosted by retail enthusiasm—amplified the magnitude of the stock’s rise.

SpaceX adopted a phased rolling unlock design rather than the traditional single 180-day unlock. According to the prospectus, sell-pressure timing is extended to at least the end of 2026. Tessera’s CEO pointed out that the supply of shares available for public trading is expected to double in late August, rise by about 6x by the end of September, and reach around one-third of the company’s total shares by November 1. When the 180-day lock-up fully matures in December, 58% of the shares will be available for trading.

The original intent of the phased unlock design is to smooth supply shocks, but its real effect still needs to be observed. Each unlock batch introduces new sell pressure into the market, and market expectations around these dates themselves may trigger front-running trades. The first post-listing earnings report is expected in August, right around when the first insiders’ lock-up period is nearing its end. The combination of earnings performance and unlock pressure may become a key window to test how strong the stock’s support is.

What large IPO first declines and subsequent trends look like from historical data

SpaceX’s first-day gain was 19.22%, roughly in line with the 21.6% average first-day gain for IPO stocks from 1990 to 2025. However, the follow-on performance of large IPOs often disappoints.

Jefferies research shows that since 2000, large IPOs with market caps above $10 billion have averaged a 26.5% return in their first week after listing, but after a full year, the return drops to just 3.5%. Between 2011 and 2024, new shares averaged a 23% first-day gain, but on a one-year basis calculated from the first day’s closing price, the average return was negative 1.7%. Looking at the top 10 IPOs in the US from 1999 to 2023, 80% of companies saw their share prices fall within three months after listing, with an average decline of 13%.

SpaceX has similarities with Saudi Aramco’s IPO—both saw their market caps surpass $2 trillion shortly after listing. After Saudi Aramco’s 2019 listing, it went through a long period of stock-price consolidation. Historical data does not constitute a prediction, but it provides a reference framework: the “honeymoon period” premium for large IPOs often faces mean reversion pressure over the medium term.

SpaceX’s special case is that its narrative is more multidimensional—three engines layered together: aerospace, satellite internet, and artificial intelligence—along with an extremely scarce float. These factors could delay valuation mean reversion, but they could also amplify the scale of adjustments when negative catalysts appear.

Countdown to lock-up expiration and the earnings window—which dates may be key tests?

After SpaceX’s first decline, market attention is shifting to several key time points.

On July 7, the Nasdaq will forcibly include SPCX, which is expected to trigger passive buying of $8 billion to $18 billion. Passive inflows may provide near-term support, but they could also become a liquidity window for some investors to reduce positions.

In August, SpaceX will release its first earnings report after listing. This will be the first chance for the market to review its financial performance as a public company. The gap between the $4.9 billion net loss in 2025 and the growth expectations for 2026 will be the focus of debate among bulls and bears.

From late August through the end of the year, phased lock-up releases will gradually release new tradable shares. The supply of shares available for trading will expand from extremely low levels to more than one-third of the total share base within several months. Changes in the supply curve themselves will form structural pressure on prices.

Paul Meeks, head of technology research at Freedom Capital Markets, believes SpaceX’s stock price may have already reached a peak in the short term, and that a larger decline may have already begun. The CIO of One Point BFG Wealth Partners noted that with such a high valuation, SpaceX must deliver actual performance, which at least takes several years to achieve.

Summary

SpaceX’s first down close since going public—down 4.95% to $191.82—marks the official end of the IPO honeymoon period. This pullback is not an isolated price fluctuation, but the result of multiple factors intertwining: a shift in macro interest rates, extreme valuation, very high implied volatility, and a scarce float structure.

From a longer-cycle perspective, SpaceX’s valuation narrative still looks compelling—its intersection of commercial space, satellite internet, and artificial intelligence does form a unique growth logic. However, a $2.51 trillion market cap has already priced in extremely optimistic expectations for the future. In a hawkish rate environment, any signal that fundamentals fall short of expectations—or any signal that the supply of shares comes in above expectations—could trigger a larger-scale valuation reset.

After the first decline, market focus is shifting from “how high it can go” to “how long it can hold.” Over the coming months, earnings disclosures, lock-up expirations, and index inclusion will each test the quality of this “first stock in space.”
