Bears Circle Wolfspeed as AI Shorts Hit New Highs

WOLF has become the most extreme short in the US mid-cap space. Short interest hit 104.7% of free float as of June 22 — up from 88.9% just seven days earlier. That 15.8 percentage point jump in a single week is striking. Zero shares remain available to borrow.

The AI space is drawing fresh fire too. SHAZ (SharonAI Holdings) saw its SI % FF jump from 26.6% to 49.1% over the week. CBRS (Cerebras Systems) sits at 37.5%, with borrowing near impossible — availability is flat zero.

CRWV (CoreWeave), the Nvidia-linked cloud AI play, holds a notable 22.2% SI % FF. Availability is still relatively high at 320%, meaning more short pressure could build. SpaceX's debut rally reversing sharply — down 16% per FT — is adding broader unease to speculative names.

On the short-cover side, CRM (Salesforce) saw shorts retreat. SI % FF fell from 6.7% to 4.5% this week. CRSP also saw covering, dropping from 24.3% to 21.3%.

Mega-caps remain calm. TSLA, NVDA, and AAPL all sit below 3% SI % FF with almost no weekly movement. Bulls hold firm on those names — bears are hunting elsewhere.
