After bankruptcy, he was banned from sports betting sites. Then he found Kalshi

Jordan Bookman, a former professional sports bettor who was banned from several sports betting sites due to his addiction, found an alternative platform called Kalshi, which allows users to bet on real-world events with cash prizes. Kalshi's CEO, Joshua Fritz, aims to reduce the risk of addiction by not allowing users to bet on games or events that have already started. The platform focuses on prediction markets, where users can bet on the outcome of events such as the S&P 500 index or the US unemployment rate. Users can also create their own markets, and the platform takes a 10% cut of the revenue. Kalshi is still in its early stages, but it has gained popularity among users looking for a more responsible and transparent alternative to traditional sports betting.
