Short Sellers Load Up on CoreWeave and EV Names

Short sellers made bold moves this week. CoreWeave saw the biggest jump among large-cap names. Its SI % of FF rose 4.5 percentage points in seven days to 25.7%. Bears are betting the AI cloud darling's $25B valuation is stretched.

Wolfspeed remains the most extreme short on the board among notable names. 84.4% of its free float is sold short. Availability has hit zero. There are no shares left to borrow. With a cost to borrow of 1.8%, a squeeze could get expensive fast.

The EV sector draws particular attention given fresh alt-data. California ZEV registrations crashed 37% year-on-year in July 2026, the worst Q3 reading in three years. That backdrop keeps bears active across the space. Lucid Group carries 64.3% SI % of FF. Rivian sits at 18.5%.

Levi Strauss is a fresh mover worth watching. Short interest jumped 2.9 percentage points in a week to 11.6% of float. Consumer spending concerns appear to be driving the trade.

Chewy holds 86.5% SI % of FF, one of the highest among mid-caps. Availability remains plentiful at 566%, suggesting shorts can still add pressure freely.
