How does Kalshi make money, and is it gambling? Kalshi founder Tarek Mansour explains why Kalshi works like a stock exchange, not a casino.A sportsbook makes money when you lose, so it has every reason to push out winning bettors. Kalshi takes a small fee on every trade, win or lose, which means it wants the smartest traders. Just like the New York Stock Exchange, those traders make the prices more accurate.------
