SpaceX Short‑Sale Surge Sends Stock Back to IPO Price Amid Lockup Timeline

Short sellers have piled aggressive bets on SpaceX shares as the stock retreats to its IPO price, hitting a historic short‑interest level.
The Shadow of Shorts: Massive Bets on SpaceX Equity
According to S3 Partners, 185 million SpaceX shares are now sold short, representing 29% of the public float and amounting to $25 billion in bearish wagers. Just three weeks ago, short interest was estimated at 40 million shares (about 5‑7% of float), meaning the exposure has nearly sextupled.
Lockup Calendar and Liquidity Storm
Only 5% of the company’s roughly 13 billion outstanding shares are freely tradable; the remaining 95% are locked. The first major lockup release could coincide with the Q2 earnings report, potentially adding 11% of outstanding shares to the market. Subsequent tranches of roughly 4% each are slated for release around day 70 post‑IPO, with additional unlocks tied to performance milestones. The largest block remains Elon Musk’s stake at 42%, locked until June 2027.
Starship Test: Potential Turning Point?
SpaceX’s 13th Starship test flight is scheduled for Thursday. A successful launch could prompt short sellers to unwind positions and push the stock above the $135 IPO level.
Numeric Snapshot: Scale of the Risk
Dr. Yaman Ege – The intensity of short‑seller activity pushes SpaceX’s liquidity profile to a critical inflection point. The upcoming lockup releases will flood the market with additional supply, heightening price volatility while serving as a barometer for investor risk appetite. A successful Starship test could trigger a short‑cover rally and price appreciation; absent that catalyst, elevated borrowing costs and incremental liquidity pressure may keep the stock under sustained downward bias.
