Short sellers betting against Donald Trump's DJT stock, associated with Trump Media & Technology Group and Digital World Acquisition, have faced significant challenges and losses. The stock's borrowing costs have skyrocketed, making it the most expensive U.S. stock to short, with borrowing costs over 200 times the average for U.S.-listed firms. This situation is attributed to a limited number of shares available for borrowing and a strong interest in betting against the company. As of today, short sellers have incurred $61 million in mark-to-market losses, contributing to a total of $158 million in losses year-to-date, according to S3 Partners. Experts suggest that the high borrowing rate, around 150% annualized based on the amount borrowed, coupled with the small pool of 3 million shares shorted so far, indicates that rates might normalize soon. However, the high cost and risk associated with shorting DJT stock, a SPAC, have led to caution among traders.
