SpaceX Shares Slide Below IPO Price After Starship Abort, Erasing About $1 Trillion

Rising short interest now threatens to force more selling that could deepen the stock's decline.

Overview

  • The Starship test that aborted at T‑zero on July 16 failed when several Raptor engines did not ignite, triggering an automatic abort and a planned engine swap ahead of another try early next week.
  • SpaceX stock has fallen below its $135 IPO price and has lost roughly $1 trillion in market value from its mid‑June peak as retail profit‑taking and mechanical market flows reversed early gains.
  • Short sellers have surged to about 29% of the tradable float, increasing downward pressure on a market that initially had an unusually small public float of roughly 4–5%.
  • Investors are worried about near‑term supply and financing risks because staged lockup expirations can free roughly 911.5 million shares after the company's first quarterly report and the firm has recently sold large amounts of notes while planning further debt issuance.
  • Wall Street underwriters issued broadly bullish 12–18 month targets that diverge sharply from independent warnings of steep downside, leaving upcoming public earnings, the staged share unlocks and the next Starship launches as the key catalysts to watch.
