Regulatory filings show that Gwynne Shotwell, President and COO of SpaceX, plans to sell 342,170 company shares, totaling approximately $51.96 million. This marks the first executive share reduction since SpaceX went public, occurring on the eve of Starship's inaugural orbital test (no earlier than September 28). Although the reduction is being conducted through a compliant 10b5-1 trading plan, the market still interprets it as an implicit judgment on the company's high valuation.
