Bears Pile Into CoreWeave and Lucid as EV Shorts Build

Short sellers have been busy this week. CoreWeave saw the biggest SI jump among large US names, with its short interest rising to 24.8% of free float from 21.2% over seven days. That is a 3.6 percentage point move. Bearish positioning in the AI infrastructure stock has nearly doubled since late September.

Lucid Group remains one of the most shorted US stocks. Bears hold 64.7% of its free float short. That figure crept up 1.9 points this week. The US state EV fleet has shrunk to its smallest July level in four years, according to ORTEX alt data, which does not help the bull case for EV pure-plays.

Chewy is another standout. Short interest sits at 86.7% of free float, a persistently extreme level. It has eased slightly from a peak above 92% earlier this month, which bears watching for any squeeze dynamics.

Hertz Global Holdings carries 72.3% short interest with a cost to borrow of nearly 28%. Availability has hit zero, meaning borrowing new shares to short is essentially impossible.

Wolfspeed remains heavily targeted at 83.8% of free float short, with 9.6 days to cover. EverCommerce (EVCM) leads the high short-score board, with a cost to borrow above 95%.

1-800-Flowers carries the longest days-to-cover at 25. Any squeeze there would take weeks to unwind.
