Short Sellers Target 32% of SpaceX Float as Musk Warns They Won't Survive

According to financial analytics firm S3, the number of SpaceX shares sold short has reached approximately 206 million, accounting for around 32% of the company's publicly tradable float. This makes SpaceX one of the most heavily shorted companies in the US market. Elon Musk publicly warned bears, stating that short sellers would not survive betting against his company. Such a high level of short interest sets the stage for a potential short squeeze: if positive catalysts emerge — successful launches, new contracts, or IPO-related news — the stock could surge sharply, forcing bears to close their positions at a loss. The situation is of particular interest to investors tracking the market for private companies with elevated speculative activity.
