Bears Pile Into AI Chip Name, Shorts Exit Wolfspeed

Short sellers made sharp moves this week. CBRS (Cerebras Systems) saw the biggest jump. Its SI % FF leapt from 6.3% to 32.4% in just seven days. Bears are betting heavily against the AI chip startup.

GRND (Grindr) also drew fresh attention. Short interest doubled — from 12% to 22.3% of free float. The dating app stock is now firmly in bearish crosshairs.

BIRK (Birkenstock) is another notable new entrant. SI rose from 21.8% to 29.4%. Cost to borrow is steep at 18.2% — a sign shares are hard to find. Availability is near zero.

In the rental car space, CAR (Avis Budget) holds 47.8% SI. That's up from 40.7% a week ago. Peer HTZ (Hertz) also climbed to 44.5%. Bears are circling the entire sector.

On the flip side, WOLF (Wolfspeed) saw short interest collapse. SI dropped sharply from 117% to 88.9% of free float. That's still very high — but the rapid squeeze covers suggest some capitulation by bears.

OKLO shorts also retreated. SI fell nearly 5 points to 16.7%. Nuclear energy sentiment is shifting.
