Musk Warns Short Sellers as SpaceX Stock Rebounds
Alina Collins
SpaceX shares rose 1% to $121 premarket, attempting to snap a seven-session losing streak that erased 21% of their value; Musk's direct warning to short sellers triggered the bounce, but a 17% short interest and a looming lock-up expiry signal the tug-of-war is far from over.
What exactly did Musk tell the shorts?
Musk posted on X Monday, saying institutions borrowing SpaceX stock to short it face "very low odds of survival."
Roughly 17% of SpaceX's available float is currently sold short — far above Apple's roughly 1% short interest and extreme among large-cap tech names.
This means → Musk isn't bluffing into thin air. A 17% short position gives his warning teeth: the more concentrated the shorts, the higher the squeeze risk.
Why is SpaceX's short interest so high?
The core reason is a tiny tradable float — most shares remain with early investors, locked up and untradeable.
In plain terms = fewer shares available to trade means every borrowed share accounts for a bigger slice of the float, inflating the percentage.
More stock unlocks after SpaceX reports Q2 earnings on August 4. The market fears early investors will cash out en masse, adding to recent selling pressure.
How does a short squeeze work — and what should investors watch?
A short squeeze — a chain reaction forcing bears to buy back shares — works like this: shorts cover → buying pushes the price up → more shorts are forced to cover → the price climbs further, creating a positive-feedback loop.
This means → if the bounce holds, that 17% short position could flip from headwind to fuel, driving a sharp short-term rally.
The flip side: if selling pressure surges after the August lock-up expiry, the squeeze logic breaks down and the stock could resume its slide.
Back-to-back launch setbacks — how much do they matter?
A Falcon 9 carrying 24 Starlink satellites aborted just before liftoff Monday; SpaceX said the payload was safe.
Earlier, the 13th Starship test flight was scrubbed due to an engine issue and rescheduled to July 23.
In plain terms = Falcon 9 has flown over 80 missions this year; a single abort is routine. Starship is still in development, so delays are expected — but two "no-fly" events landing on a stock-price trough amplified market anxiety.
What comes next?
SpaceX shares now sit roughly 47% below their all-time high of about $226 and have closed below the $135 IPO price for three straight sessions.
Two catalysts ahead: ① whether the July 23 Starship test flies successfully; ② the August 4 Q2 earnings and post-lock-up selling pressure.
This reflects a broader shift: the market is repricing SpaceX from a faith trade to a proof-of-performance trade — Starship and earnings both need to deliver.
