According to Business Insider on July 13, Michael Burry, known for predicting the 2008 subprime crisis, criticized prediction markets including Kalshi, claiming they exploit regulatory loopholes and function essentially as gambling. Burry argued via X that while the U.S. gambling industry faces high taxes and strict regulations, prediction markets operate in regulatory gray areas, enabling the same activity without equivalent oversight.
A 2024 report by the Roosevelt Institute found that retail users on Kalshi recorded losses exceeding $600 million since 2018, while a small group of professional traders profited significantly from structural advantages. Burry further questioned the platform's insider trading safeguards and criticized Kalshi for providing an environment where "people can gamble and deceive," emphasizing the absence of effective fraud prevention mechanisms.
