Bears Pile Into CoreWeave as Wolfspeed Breaks 100%

Short sellers are targeting AI infrastructure and beaten-down chips. CoreWeave saw its short interest climb to 33.1% of free float as of July 9. That's up from 28.3% just one week earlier — a 4.8 percentage point jump in seven days. The $40bn AI cloud firm heads into a busy earnings week under growing bear pressure.

Wolfspeed remains one of the most shorted mid-caps in the US. Short interest hit 103% of free float — up from 98.6% a week ago. The SiC chipmaker has zero shares available to borrow, making any fresh short position costly and difficult to enter.

Meanwhile, CrowdStrike saw a notable short unwind. SI dropped sharply from 2.9% to just 0.9% of free float in one week. Shorts cut exposure ahead of bank earnings season. With availability now above 7,900% of short interest, there's no squeeze risk there.

Among smaller names, Lucyd exploded from near-zero to 45.8% SI in one week. VMAR, Vision Marine Technologies, surged to 128.9% from 25.9%.

On the news front, bank earnings dominate. JPMorgan, Goldman Sachs, and Netflix all report this week. Short interest in financials remains subdued. Meta sits at just 1.4% SI. The real bear action is in AI infrastructure and distressed chips — not the mega-caps.
