Bears Pile Into CoreWeave, Wolfspeed Tops 100%

Short sellers turned aggressive this week. CoreWeave saw the biggest move among large-cap names. Its SI % of Free Float jumped to 33.7% — up 5.3 percentage points in just seven days. Bears are clearly skeptical of the AI infrastructure darling's $40 billion valuation.

Wolfspeed remains the most extreme story. SI % FF hit 103.8%, up another 2.6 points over the week. Zero availability of shares to borrow signals near-maximum bearish conviction on the struggling chipmaker.

Chewy also drew fresh shorts. SI % FF climbed to 76.1%, adding 4.3 points week-on-week. Cost to borrow stays low at 0.5%, so bears face little friction getting in.

ChronoScale Holdings is the week's stealth mover. SI surged 9.6 points in five days to 42.9%. Cost to borrow sits at a punishing 43.2%. That squeeze risk is real.

Gentex caught ORTEX attention separately. Short interest spiked 24.4% in one week to 8.5% of float — a 46% monthly climb. UBS also cut its price target today.

On the social-media favourites, GME holds at 13.6% SI FF with minimal change. TSLA shorts edged back slightly to 3.0%. PLTR remains lightly shorted at 3.7%.
