Bears Pile Into CoreWeave as Tesla Buzz Grows

Short sellers stepped up pressure on CRWV this week. CoreWeave's short interest jumped 3.66 percentage points in seven days to 23.7% of free float. That is the biggest weekly rise among US stocks with a market cap above $500 million.

TSLA is in focus today. Tesla reports Q3 2026 earnings on 21 October. German car registration data, a dataset ORTEX Alt Data measures as leading Tesla revenue by 43 days, is running 269% above Q3 2025 levels. Short interest in Tesla remains low at just 2.6% of free float, leaving bears with little ammunition.

WOLF carries the heaviest short load among larger names. Wolfspeed sits at 85.6% of free float sold short. Zero shares are available to borrow. That combination signals a crowded, illiquid short that could unwind fast.

CHWY is another name bears have circled. Chewy's SI stands at 89.2% of free float. Availability is 518%, so supply is not the constraint here. Shorts appear comfortable staying in the trade.

EVCM has the attention of short sellers too. EverCommerce carries a 96 ORTEX short score and a cost to borrow of 95%. Only 1.6% of short interest has shares available to borrow, making this one of the hardest stocks to short further.

A SpaceX-Tesla megamerger story is circulating on social media today. The news has an impact score of 12 out of 10 on ORTEX. With TSLA shorts already thin, any positive catalyst could catch bears offside quickly.
