Surging Short Interest in SpaceX Stock Sends Strong Signal to Wall Street

Short interest in SpaceX stock surged to 219.3 million shares as of July 29, according to data from S3 Partners cited by Bloomberg—about 34% of the shares currently available for public trading. That’s up from 23.3 million shares when S3 began tracking on June 16, and the bearish position is valued at roughly $24.6 billion, exceeding the amount bet against Tesla. Bloomberg reports traders are focusing less on SpaceX’s first earnings report and more on expectations that upcoming share releases will add supply. SpaceX is set to report Aug. 4, with lockup expiration starting Aug. 6, potentially making as many as 911.5 million shares eligible.
