Short sellers are placing multi-billion dollar bets that the surge in cryptocurrency-linked stocks, driven by a Bitcoin rally, will come to a halt. According to a report from S3 Partners LLC, the total short interest against crypto stocks has reached nearly $11 billion this year. A significant portion of the short interest is focused on MicroStrategy Inc. and Coinbase Global Inc., accounting for over 80% of the total bet. The substantial increase in short interest indicates skepticism about the sustainability of the current rally in cryptocurrency-related stocks.
