Short sellers ramped up positions in several notable names this week. Marqeta saw the biggest jump. Its SI % of Free Float leapt from 3.95% to 14.47% in just seven days — a 10.5 percentage point spike.
CoreWeave, the AI cloud darling, is also attracting heavy scepticism. Short interest now stands at 33.7% of free float, up 5.3pp over the week. Despite a $40bn market cap, bears are not convinced the AI spending boom justifies the valuation.
Chewy remains one of the most shorted large-caps. SI hit 76.1% of free float. The pet retailer's stock has struggled with profitability concerns.
Wolfspeed holds the extreme end. Short interest exceeds 100% of free float at 103.8%. Its cost to borrow has climbed to 8.7% APR. Availability is effectively zero — borrowing shares is nearly impossible.
On the covering side, Quantinuum saw shorts retreat by 3.4pp. Cerebras Systems also saw covering, down 2.8pp.
Strategy Inc remained in focus after Michael Saylor's Bitcoin sales drew social media attention. Its short interest sits at 11.8% of free float, with CTB at just 0.57% — shorts are cheap to hold.
