Shares of SpaceX (SPCX) advanced 7.2% during Monday’s session, ending the day at $164.19 following the company’s formal entry into the Russell 1000 index.

While the gain is noteworthy, context matters. The stock continues to trade substantially beneath its all-time high of $225.64, which was reached shortly after the company went public on June 12.
The Russell 1000 officially added SpaceX shares after the market closed Friday. Monday represented the first complete trading session reflecting this index membership.
Meanwhile, S&P Global decided against expediting SpaceX into its benchmark indexes. The decision hinges on liquidity constraints.
Currently, approximately 86 million SpaceX shares are freely tradable. Compared to the company’s total share count exceeding 13 billion, this represents an extremely limited float—insufficient to absorb the substantial demand from passive S&P 500 index funds at this time.
Additional shares are expected to become available for trading over the coming months. In the meantime, the more immediate catalyst arrives July 7, when SpaceX enters the Nasdaq-100.
This addition should generate purchasing activity from major funds such as the Invesco QQQ ETF. All three major indexes calculate weightings based on available float rather than total outstanding shares, meaning actual market influence depends on tradable supply.
CEO Projects Strong Revenue Growth
Elon Musk contributed to the positive momentum over the weekend. Commenting on projections that SpaceX could reach $100 billion in annual revenue by 2028, he stated he would feel “disappointed” if the company failed to substantially exceed that figure.
Analyst consensus currently places 2028 revenue estimates near $103 billion, meaning Musk’s statement aligns closely with existing forecasts. He additionally suggested that SpaceX’s Grok 4.5 artificial intelligence model would deliver superior performance compared to competing systems from Anthropic.
Grok originated at xAI, which completed a merger with SpaceX in February. That separate entity has since been fully integrated into SpaceX operations.
Monday’s performance stood out against broader market movements. The S&P 500 climbed 1.2% while the Dow Jones Industrial Average added 0.6%, both lagging SpaceX’s advance considerably.
At present trading levels, SpaceX commands a market capitalization approaching $2 trillion. The stock’s lowest point since going public was $147.11, which remains well above its $135 IPO pricing.
Historical IPO Performance Raises Red Flags
SpaceX generated $85.7 billion through its initial public offering, shattering previous records. However, the company sold only approximately 4% of its total equity to public market participants.
This structure has significant implications for what lies ahead: share dilution. Restrictions on insider and early-stage investor holdings begin expiring shortly, with the initial wave hitting in August.
This first unlock event will effectively double the publicly available share supply. Historical precedent for massive, heavily-promoted IPOs during their inaugural year offers sobering lessons.
Facebook, Rivian, and Robinhood each experienced substantial declines during their first year as public companies. Saudi Aramco, despite being among history’s largest IPOs, dropped 23.3% within its first three months of trading.
A comprehensive Truist analysis examining the 30 largest recent IPOs revealed average returns hovering around -9% at both six-month and twelve-month intervals. Research from University of Florida professor Jay Ritter indicates that larger, more established companies have generally performed better than smaller counterparts following their public debuts.
Just twelve months ago, SpaceX carried a valuation near $500 billion, including xAI. This means the current $2 trillion-plus market cap already reflects extraordinary growth expectations—all coming to a head before the August unlock event materializes.
