Bears Pile In: AI Stocks Dominate Short Surge

Short sellers are moving fast this week. Cerebras Systems saw the biggest single-week jump — SI % FF leapt from 6.25% to 25.6% in just seven days. That's a 19-point spike. Bears are clearly skeptical of the AI chip firm's rally.

CoreWeave also drew fresh shorts. SI climbed 20% in a week to 15.9% of free float. But availability sits at a whopping 569% of SI — plenty of room to squeeze if bulls push back.

The most alarming signal belongs to Rezolve AI. Cost to borrow exploded to 53.4% APR — up 125% in one week. Shares available for lending are near zero. That's a textbook short squeeze setup heading into June 26 earnings.

Grindr shorts doubled to 22.2% of float this week. The dating app stock now carries meaningful bearish pressure.

In rental cars, Avis Budget and Hertz both sit above 44% SI % FF, with another 4-6 point rise this week. Short sellers remain firmly in control.

Meanwhile, Microsoft shorts collapsed — down 48.5% in one week to just 0.27% of float. Big tech bears are retreating.
