CoreWeave topped the week's short interest movers among large caps. SI as a percentage of free float rose 3.6 points to 24.8% in seven days. The AI cloud company carries a $25.5 billion market cap, yet bears continue to build positions ahead of its next earnings.

Wolfspeed remains the most heavily shorted semiconductor name, with SI at 83.8% of free float. Short sellers are not moving on, despite a 10-day borrowing cost of just 1.9%.

Chewy told a different story. SI fell 4.6 points to 86.7% of free float this week. That is notable covering. The stock still sits near the top of any heavily-shorted list, but the direction has shifted. Short sellers trimmed around 534% worth of shares relative to existing short interest are available to borrow, leaving plenty of room for a squeeze.

Fabric.AI carries an ORTEX short score of 92.8 and a cost to borrow of 236%. Bears are paying a steep price to stay short there.

On the alt-data side, US registered battery-electric vehicles fell to a four-year low in July 2026, according to state fleet data. That backdrop keeps pressure on EV names. Rivian short interest holds steady at 18.3% of free float.
