SpaceX short interest jumps to 13% after shares slide about 30% from post-IPO high

SpaceX has been public for only two weeks, but short interest has climbed to 13% from 8%, representing roughly 83 million shares sold short. The stock is down about 30% from its post-debut peak. Borrow costs remain low at around 1% while utilization has risen to 39%, suggesting active short positioning alongside ample stock available to lend. The shift underscores widening investor disagreement over the company’s $2 trillion valuation and the pace of profit delivery.
