- Palantir (PLTR:NASDAQ) stock surged approximately 29-30%, narrowly missing its single best trading day ever, after reporting what CNBC quoted as "otherworldly" results
- Short sellers sustained roughly $3 billion in mark-to-market losses as the rally accelerated, per Seeking Alpha's tally
- Forbes framed the move as Palantir "bucking investors' AI fears," positioning the surge against broader sector anxiety over AI-related valuations
Why it matters: A ~30% single-session move that cost shorts an estimated $3B is a violent repricing event—bears betting against PLTR absorbed the bulk of the damage, while the rally's framing as a rejection of 'AI fears' suggests results were strong enough to overwhelm sector-wide skepticism rather than ride it.
