Bears Pile Into SpaceX and GameStop Returns to the Radar

Short sellers are on the move this week. The biggest story in the data is BRVE (Braveheart Bio), where SI as a percentage of free float has rocketed to 277% — up from 191% just seven days ago. That 86-point jump is the largest weekly move tracked across mid-cap names right now.

GME is back in focus. GameStop's short interest surged to 7.2% of free float on September 21, up from under 1% a week prior. It had been drifting as low as 0.26% just days before. Social platforms have already picked up on the spike, with Reddit threads noting the pattern mirrors early 2021 setups — though the float dynamics today are very different.

SPCX (SpaceX) also caught fresh shorting interest. SI climbed to 29.4% from 23.2% last week — a notable move for a $2 trillion-cap name. The stock is flat over three months but bearish pressure is clearly building.

WOLF (Wolfspeed) remains a structural short. SI stands at 82.3% of free float with 9.7 days to cover and a cost to borrow of just 2.2% — bears remain comfortable holding the position.

On the high-score list, LUCK (Lucky Strike Entertainment) carries a short score of 95 with 26 days to cover and a cost to borrow near 27%. Shares are down 31% in three months, giving shorts little reason to cover.

XNDU (Xanadu Quantum Technologies) also stands out, with short interest exceeding 101% of free float and availability collapsing to just 6.9% — indicating very few shares remain available to borrow.
