Bears Pile Into CoreWeave, Squeeze Risk Builds in Chewy

Short sellers sharpened their bets across several high-profile names this week. CoreWeave saw the biggest move among large-caps. Its short interest rose 3.6 percentage points in seven days to 24.8% of free float. Bears are clearly sceptical of the AI infrastructure rally, even as Taiwan's export orders hit a record $114bn in September, a figure that underscores the region's semiconductor demand.

Wolfspeed remains one of the most heavily shorted stocks on US exchanges. Short interest sits at 83.8% of free float. Zero shares are currently available to borrow. That makes new short positions almost impossible to open, and raises squeeze risk for anyone already in the trade.

Chewy is moving the other way. Short interest fell 4.6 points over the week to 86.7% of free float. With 605% availability, there is no shortage of stock to borrow. But the still-extreme level keeps it firmly on the watchlist.

JetBlue drew fresh attention after a WSJ report said creditors huddled with a restructuring adviser as bonds and shares fell. Short interest stands at 30.9% of free float.

BKV Corporation, the US natural gas producer, saw shorts build steadily. Its SI hit 38.6% of free float, up 3.9 points on the week. Fabric.AI carries an ORTEX short score of 92.8 and a cost to borrow of 236%, signalling extreme bearish positioning in a micro-cap name.

Massachusetts online sports wagering revenue rose 34% year-on-year in September to $72.2m, per ORTEX alt data, a tailwind that may complicate bearish theses in gaming-adjacent names.
