Bears Pile Into Wolfspeed and Cerebras

Short sellers hit hard this week. Two names saw dramatic increases in bearish bets — and both sit firmly in the AI and semiconductor space.

Wolfspeed leads the charge. SI as a % of free float hit 104.7%, up from 88.9% just seven days ago. That 15.8 percentage-point jump is eye-catching. Bears are near-unanimous on the struggling SiC chipmaker. Zero shares are available to borrow — a classic squeeze setup, yet sellers keep piling in.

Cerebras Systems is also in the crosshairs. SI rose from 32.4% to 37.5% this week. News is circling too — headlines are asking whether AI's biggest bottleneck is energy, not chips. The stock appears on investor radars. Short sellers disagree with the bulls.

On the flip side, shorts covered at Salesforce. SI dropped from 6.7% to 4.5% in seven days. Bears are quietly retreating there.

Mega-caps remain lightly shorted. NVIDIA sits at just 1.3% SI. Meta is at 1.5%. Both face regulatory headlines but shorts are not biting.

Snap is the most-shorted big social name at 9.3%. Legal pressure from teen addiction lawsuits adds to the bearish case.

Tesla SI holds low at 3.0%. Rate-rise fears and Nasdaq weakness aren't driving new short bets there.
