Bears Pile In: GME Reawakens, SpaceX Shorts Climb

Short sellers got busy this week. The biggest mover in the data is BRVE (Braveheart Bio), with short interest hitting a staggering 367% of free float — up from 223% just seven days ago. That 144-point jump is the sharpest weekly rise across stocks with a market cap above $500M.

GME is back in the spotlight. Short interest jumped from under 1% to 7.2% of free float in a week — a move that will ring alarm bells for bears who remember meme-stock history. Cost to borrow remains cheap at 0.46%, but availability at 240% means shorts can still pile in easily. Social media chatter around GameStop has picked up again.

SPCX (SpaceX) saw its SI % FF climb from 21.8% to 29.4% over the week. Bears are pressing against one of the market's hottest names. With META reaching a $1.98 trillion valuation this week on AI hype, shorts appear to be rotating into other high-flying tech and space plays.

WOLF (Wolfspeed) remains deeply shorted at 80.3% of free float. Zero shares are available to borrow — a classic short squeeze setup if any positive catalyst emerges.

CHWY holds at 74.9% SI % FF, yet borrow availability sits at 431%. That unusually high availability signals the crowd is watching, but no squeeze pressure yet.
