Bears Circle Wolfspeed as SI Tops 130%

Wolfspeed is the most heavily shorted stock among US-listed firms with a market cap above $500M. Short interest hit 129.9% of free float as of June 26. That jumped 26 points in just one week. The chip maker has been a persistent short target, but last week's move signals fresh bearish bets piling in.

WaterBridge Infrastructure is a new short-seller favourite. SI surged from 31.8% to 85.2% — a 53-point spike in seven days. That is one of the sharpest weekly moves in the entire market.

On the squeeze side, Faeth Therapeutics saw shorts exit fast. SI dropped from 130.9% to 85.1%, a 46-point fall in a week. SharonAI Holdings shed 44 points, falling from 54.6% to 10%. Avis Budget Group eased 6 points to 38.2%.

Among social-media favourites, GameStop sits at 13.8% SI. Palantir bears are quietly building, up to 3.5% with analysts debating AI competition. Tesla remains lightly shorted at just 2.9%.

Chewy holds the highest SI among larger caps at 68.1%, with a cost to borrow of just 0.42% — cheap to hold the bet.
