Short sellers betting against SpaceX have amassed about $4 billion (£3 billion) in paper profits after shares in Elon Musk's rocket and satellite company tumbled below their record-breaking initial public offering price, making it one of Wall Street's most heavily shorted stocks barely a month after its market debut.
Data from S3 Partners, a US financial analytics firm that tracks short-selling activity, shows about 30% of the roughly 640 million publicly tradable SpaceX shares have been borrowed by investors betting the stock will decline further.
