SpaceX shares dropped below their initial public offering price of $135 for the first time since the company listed on Nasdaq, extending a four-session losing streak. The stock decline comes just days after the rocket manufacturer made its debut on the Nasdaq-100 index.

The pullback reflects profit-taking following SpaceX's highly anticipated market entry. Institutional investors who accumulated positions ahead of the IPO have begun exiting positions, a pattern typical for newly public companies that generate substantial opening-day momentum. The timing of this decline suggests limited immediate catalysts to sustain elevated valuations.

SpaceX's entry into public markets represented one of the year's most significant corporate actions. The company achieved unicorn status long ago through private funding rounds, but going public provided liquidity for early employees and investors while raising capital for accelerating Starship development and satellite constellation expansion.

The stock's weakness may also reflect broader market sentiment toward aerospace and defense stocks. The sector faces headwinds from rising interest rates, which increase the cost of capital-intensive projects like SpaceX's space infrastructure initiatives. Competition intensifies from Blue Origin, which benefits from Amazon's backing, and from established defense contractors like Lockheed Martin and Northrop Grumman that have strengthened their space divisions.

SpaceX generates revenue through multiple channels. Government contracts with NASA and the Department of Defense provide stable, long-term revenue. Starlink, the satellite internet division, drives growth but requires continuous capital deployment. Commercial launch services remain highly competitive, though SpaceX commands roughly 60 percent market share globally.

The below-IPO pricing raises questions about valuation sustainability. Pre-IPO investors paid significantly more per share than current market levels, creating pressure for the company to deliver on aggressive growth projections. Management guidance on profitability timelines and return on capital deployment will become critical for supporting the stock above IPO levels.

Investors holding SpaceX shares should monitor quarterly revenue growth rates, particularly Starlink subscriber additions and churn metrics, plus contract wins from NASA and the Pentagon. Watch for any guidance revisions on profitability timelines or capital expenditure plans.
