Bears Target Cerebras as Wolfspeed Shorts Bail

Short sellers made a decisive move into CBRS last week. Short Interest as a % of Free Float surged from 6.3% to 32.4% in just seven days. That's a jump of more than 26 percentage points. Cerebras, the AI chip startup that went public last year, is drawing serious bearish attention despite a $7.4 billion market cap.

GRND also saw shorts pile in. Grindr's SI % FF doubled from 12% to 22.3% over the same period. BIRK hit 29.4% SI % FF, up from 21.8%. Birkenstock's cost to borrow jumped to a steep 18.2%.

Rental car stocks remain under heavy pressure. CAR Avis Budget sits at 47.8% SI % FF, while HTZ holds at 44.5%. Both saw shorts increase positions by roughly 4–7 points this week.

On the covering side, WOLF Wolfspeed saw its SI % FF fall sharply — from 118% to 89.6%. That's a 28-point drop. Short covering at Wolfspeed is notable. The stock remains one of the most shorted on the market.

PLTR Palantir made headlines today after refuting reports that France's DGSI security service ended its partnership. SI % FF there remains low at 3.2%. TSLA and NVDA both have minimal short pressure, at 2.8% and 1.3% respectively. GME GameStop holds at 13%, largely off the radar for now.
