On August 11, SpaceX declined 3.16% in regular trading, trading at $134.31/share with turnover of $20.43 billion, after briefly rising over 3% in pre-market before reversing sharply lower.

The decline was driven by a notable shift in retail investor sentiment. According to Vanda Research data, retail investors became net sellers of SpaceX stock for the first time since the company's June IPO, offloading a net $4.5 million on August 7. This marked the first net negative retail flow reading since going public.

Compounding the selling pressure, the first post-IPO lock-up period expired last Thursday, releasing over 911 million previously restricted shares into the market. This more than doubled the publicly tradable float from 639 million shares at IPO to approximately 1.55 billion shares, significantly expanding supply-side capacity. While the stock had surged roughly 23% in the two sessions immediately following the unlock — defying initial expectations of heavy insider selling — the broader sentiment reversal among retail participants and increased supply overhang weighed on shares during regular trading.
