<p><a href="/quotes/SPCX/" target="_blank" rel="noopener noreferrer">SpaceX</a>'s sharp pullback from its post-IPO record high is doing little to embolden short sellers reluctant to bet against CEO <a href="https://www.cnbc.com/elon-musk/" target="_blank" rel="noopener noreferrer">Elon Musk</a>, even as the shares have shed more than a quarter of their value in just over a week.</p>
<p><a href="https://www.cnbc.com/2026/06/23/spacex-stock-tech-sell-off.html" target="_blank" rel="noopener noreferrer">The rocket company is down</a> about 12% this week and roughly 28% from its June 16 peak, erasing hundreds of billions of dollars in market value after a blistering rally that followed the June 12 initial public offering.</p>
<p>Yet bearish bets remain in check. Only about 40 million SpaceX shares are currently sold short, representing roughly 5% to 7% of the company's publicly tradable float of roughly 625 million shares, according to an estimate by S3 Partners.</p>
<p>Short selling refers to a trading strategy that allows investors to bet that the price of a stock or security will fall. </p>
<p>About 60 companies in the S&P 500 currently have short interest exceeding 7% of their float, according to FactSet, suggesting bearish positioning in SpaceX remains relatively modest despite the stock's recent slide.</p>
<p>More than 30 million SpaceX shares are currently available to borrow, indicating ample liquidity in the securities lending market. Borrowing costs are also low, with annualized fees below 1%, S3 said.</p>
