TLDR
- SpaceX lost an estimated $39.5 billion in market value after a 2.2% decline.
- Rocket Lab led peer gains, but combined advances failed to offset SpaceX’s slide.
- MDA surged after raising $819 million to support its planned CLS acquisition.
- Investors now await Starship Flight 13 as the next major catalyst for SpaceX shares.
SpaceX (NASDAQ: SPCX) ended Tuesday under pressure, shedding 2.2% and erasing an estimated $39.5 billion in market value despite a broadly positive trading session for growth stocks.
While several other companies in the space sector, including Rocket Lab USA (NASDAQ: RKLB), MDA Space (NYSE: MDA), and AST SpaceMobile (NASDAQ: ASTS), finished the day higher, their combined gains were too small to counterbalance the decline in the industry’s largest publicly traded player.
The contrasting performances highlighted how the sheer size of SpaceX continues to shape investor sentiment across the broader space industry. Even though its smaller peers collectively added roughly $2 billion in market capitalization, SpaceX’s loss outweighed those gains by nearly twentyfold.

SpaceX Dominates Sector Moves
SpaceX shares closed at $136.08, only marginally above the company’s $135 initial public offering price. The stock now trades nearly 40% below its June peak of $225.64, reflecting continued investor caution despite optimism surrounding the company’s long-term growth prospects.
The decline stood out because it occurred on a day when technology and other high-growth stocks generally moved higher. The Nasdaq Composite advanced approximately 0.9% after fresh inflation data showed U.S. consumer prices cooling in June, strengthening expectations that the Federal Reserve may avoid another interest rate increase in July.
Typically, lower interest-rate expectations benefit companies whose valuations depend heavily on future earnings, making SpaceX’s underperformance particularly notable.
Although the stock initially traded higher following the opening bell, selling pressure emerged later in the session, pushing shares into negative territory by the close.
Peers Extend Strong Gains
While SpaceX struggled, several space-related companies attracted fresh buying interest.
Rocket Lab delivered one of the strongest performances among major space stocks, climbing 2.7% and contributing approximately $1.25 billion in additional market value. The company accounted for more than 60% of the combined gains generated by the three smaller firms.
MDA Space posted the largest percentage increase, rising 7.8% after successfully completing a 23 million-share offering priced at $35.60 per share. The financing generated approximately $819 million, providing fresh capital to help fund its planned acquisition of roughly 70% of French satellite data company CLS.
Management believes the acquisition could significantly strengthen MDA’s Earth observation business while potentially doubling recurring revenue once completed. Despite Tuesday’s rally, however, MDA still finished below its recent offering price, suggesting investors remain cautious as regulatory approvals and transaction milestones are still pending.
AST SpaceMobile also advanced 1.8%, adding roughly $360 million in market value as investors maintained confidence in the company’s satellite-based mobile broadband ambitions.
Analysts Remain Constructive
Despite recent weakness, Wall Street continues to view SpaceX as one of the industry’s premier long-term growth stories.
Evercore ISI recently initiated research coverage with an Outperform rating and established a $230 price target, implying substantial upside from current trading levels. The investment firm praised the company’s ambitious technological roadmap while acknowledging that significant operational milestones still lie ahead before that potential can be fully realized.
Those milestones may arrive sooner rather than later.
Investors are closely watching the planned Starship Flight 13 launch, expected as early as Thursday. A successful mission could reinforce confidence in SpaceX’s long-term execution capabilities and help shift market attention back toward operational progress rather than recent share price weakness.
Conversely, another unsuccessful launch could deepen investor concerns regarding execution risk, particularly after the stock’s steep decline from its June highs.
Key Catalysts Ahead
Beyond launch activity, investors will also monitor potential changes to SpaceX’s share supply.
Market observers have noted that following the company’s first earnings report, previously restricted shares could become eligible for trading, potentially increasing the stock’s available float. Any meaningful rise in supply could create additional short-term pressure even if the company’s underlying business continues to expand.
Meanwhile, MDA’s acquisition financing, Rocket Lab’s steady momentum, and AST SpaceMobile’s continued execution illustrate that capital continues flowing into selective areas of the space economy rather than the industry as a whole.
Tuesday’s trading session underscored that percentage gains alone do not tell the full story. Although several space stocks outperformed SpaceX on a relative basis, the company’s immense market capitalization meant its modest decline erased far more value than competitors were able to create.
As investors await Starship’s next launch and additional corporate developments across the sector, the performance of SpaceX remains the single biggest factor influencing overall sentiment in publicly traded space equities.
