How BetMGM compares to Kalshi

BetMGM is a traditional state-regulated sportsbook — you bet against the house, and prices include vig (typically 4-5% on standard game lines). Kalshi is a CFTC-regulated event-contracts exchange where prices are set by user bid/ask; there's no traditional vig, just spread. On the same MLB or NBA moneyline, Kalshi mid-prices often beat BetMGM's no-vig fair line by 2-8 percentage points, with the gap widening on futures and player props.
