Bears Double Down on SpaceX, CoreWeave Shorts Flee

Short sellers made fresh bets across several names this week. The biggest mover was SPCX, the SpaceX tracking stock, where SI % FF rose to 36.4% — up 3.6 percentage points in seven days. Shares to borrow are nearly gone, with availability at just 0.16%.

CoreWeave told a different story. Bears retreated sharply after earnings. SI % FF sits at 20.2%, with availability at 215% — plenty of room for shorts to cover further. ORTEX flagged the print as a key inflection point, with Monday's session set as the next test.

Hertz remains a pain trade for bears. SI % FF stands at 65.4%, and zero shares are available to borrow. With 12 days to cover, any rally could hurt.

Galectin Therapeutics carries the highest short score at 90. SI % FF hit 76.6%, with a cost to borrow of 14.3%. Only 21% availability remains. That squeeze risk is real.

On the unwind side, Chewy saw SI drop nearly 5 points in a week to 102%. That is still extreme, but the direction has shifted. Availability at 392% gives shorts room to exit.

RingCentral saw the sharpest mid-cap build-up among software names. SI jumped from 12.2% to 15.1% in seven days.
