SpaceX Stock Surges 37% in First Week Despite Two-Day Pullback, Market Value Ranks Sixth Globally
SpaceX concluded its first week as a public company with a 37% gain despite a sharp two-day pullback, closing at $185 per share. Retail investor participation, limited float, and broader market weakness drove volatility, though the company's $2.4 trillion market value ranked it sixth globally. Upcoming inclusion in major indices could provide support for the stock.

SpaceX completed its first week as a public company with significant volatility, closing Friday with a 37% gain from its $135 IPO price despite a sharp two-day correction. The stock debuted on June 12 with a dramatic rally that briefly propelled SpaceX to become the world's fifth-largest company by market capitalization, exceeding Amazon. However, the stock experienced consecutive declines over June 17-18, with a cumulative pullback of 8.3%, closing at $185 per share on June 18 and bringing the company's total market value to approximately $2.4 trillion, ranking it sixth globally.
Market analysts attributed the volatility to multiple factors. The IPO included a notably high retail investor allocation of 20%—approaching the initially projected maximum of 30%—significantly higher than typical offerings. According to Vanda Research, SpaceX became the largest net buy among retail investors before the pullback, attracting more capital inflows than Nvidia, Alphabet, Amazon, and Meta Platforms combined. The limited float, representing only 4.2% of total shares on the first trading day, amplified price swings. Additionally, broader market weakness on June 17, when the Federal Reserve maintained interest rates and the Nasdaq declined 1.34%, contributed to the correction.
Some investors appear to be rotating from Tesla—which saw $61 million in net selling—to SpaceX, increasingly viewing the space company as a play on artificial intelligence and technology. Investment professionals offered differing perspectives on the pullback: Roundhill Financial's president Dave Mazza characterized it as normal profit-taking after a near-vertical ascent, while Founder Funds' Michael Monaghan noted that despite high investor expectations for revenue growth, the path to achieving those targets remained unclear.
Looking ahead, Nasdaq's recent rule changes permitting faster inclusion of large newly listed companies could accelerate SpaceX's entry into major indices. SpaceX may qualify for inclusion in the Nasdaq-100 index just 15 trading days after listing, which could generate passive buying pressure from tracking funds. However, S&P Dow Jones Indices has not yet adjusted its standards, meaning SpaceX will not enter the S&P 500 in the near term—companies typically must list for at least 12 months and meet profitability requirements. Future lockup expirations for insider shareholders are expected to increase share supply and could pressure the stock over coming months.
Why This Matters
SpaceX's IPO and subsequent market behavior offer critical insights into retail investor sentiment, market structure dynamics, and valuation risks in mega-cap tech listings. The 37% first-week gain despite volatility signals strong investor appetite but also highlights fragility—with limited float and high retail participation amplifying price swings. The two-day pullback illustrates how broader macroeconomic signals (Fed policy, market weakness) can quickly reverse euphoria. For investors, this underscores the importance of understanding lockup expirations and index inclusion timelines, which will likely reshape supply-demand dynamics. The potential rotation from Tesla to SpaceX reflects evolving perceptions of AI-adjacency and growth prospects, making this a bellwether for how capital allocates across the tech/space sector.
