Sports betting on Kalshi feels really inefficient right now Example of a trade that seems like free money right now (please tell me where I'm getting anything wrong) 1. Sinner v Djokovic -- buy $100 worth of Sinner at 69c for a payout of $142 if he wins 2. On who wins the tournament -- buy $42 worth of Djokovic for 15c If Djokovic wins the semis, you lose $100 on Sinner. But if that means Djokovic's odds of winning the tournament increase to 40c, your $42 position can be sold for $112 -- for a total payout of $12 (8.5% return on capital deployed)
