SpaceX (SPCX) shares advanced 7.2% during Monday’s session, settling at $164.19. The upward movement coincided with the company’s formal entry into the Russell 1000 index.

While the gain is noteworthy, context matters. The stock continues trading substantially beneath its post-IPO peak of $225.64, recorded shortly after its June 12 market debut.
The Russell 1000 added SpaceX shares following Friday’s market close. Monday represented the initial complete trading session with this index membership active.
Meanwhile, S&P Global declined to expedite SpaceX into its benchmark indexes. The decision stems from straightforward supply-and-demand considerations.
Approximately 86 million SpaceX shares currently exist in the tradable float. This represents merely a sliver of the company’s 13 billion-plus outstanding shares—insufficient to accommodate substantial passive S&P 500 fund purchases at this stage.
Additional float should become available throughout the coming half-year. Meanwhile, the more immediate catalyst involves the Nasdaq-100, which adds SpaceX on July 7.
This addition should generate demand from vehicles such as the Invesco QQQ ETF. All three indexes employ float-weighted methodologies, meaning actual market effects depend on tradable share counts rather than total outstanding shares.
Musk Discusses Revenue Projections
Elon Musk contributed to the weekend momentum as well. Reacting to commentary about SpaceX achieving $100 billion in 2028 revenue, he expressed he would feel “disappointed” should the company fail to exceed that figure.
Current Wall Street consensus places 2028 revenue near $103 billion, meaning Musk’s statement isn’t particularly bold. He additionally suggested SpaceX’s Grok 4.5 AI system might surpass competing models from Anthropic.
Grok originated at xAI, which combined with SpaceX this past February. That separate entity has since been fully integrated into SpaceX.
Monday’s performance looks particularly strong when measured against broader market movements. The S&P 500 advanced 1.2% while the Dow climbed 0.6%, both lagging SpaceX’s percentage gain considerably.
At present trading levels, SpaceX commands approximately $2 trillion in market capitalization. The stock’s post-IPO floor was $147.11, maintaining a comfortable cushion above its $135 IPO pricing.
Historical Patterns for Large-Scale IPOs
SpaceX generated $85.7 billion through its IPO, exceeding the previous benchmark by more than double. However, merely 4% of company equity was actually transferred to public market participants.
This distinction carries weight given upcoming developments: dilution. Shares held by insiders and early backers begin unlocking shortly, with the initial wave arriving in August.
This first unlock event alone will double the publicly tradable share count. Historical precedent proves unforgiving for heavily promoted, large-scale IPOs during their inaugural year.
Facebook, Rivian, and Robinhood all experienced substantial first-year declines following their public debuts. Even Saudi Aramco, among history’s largest IPOs, dropped 23.3% during its initial three months.
A Truist analysis examining the 30 largest recent IPOs discovered average returns hovering around -9% at both six-month and twelve-month intervals. Larger, more established enterprises have historically outperformed smaller counterparts, based on research conducted by University of Florida professor Jay Ritter.
SpaceX carried a valuation near $500 billion just twelve months prior, including xAI. This indicates substantial growth expectations have already been embedded in the current $2 trillion-plus valuation, all preceding the August share unlock event.
