Pick your state to see today's best price on every game, computed across only the sportsbooks you can legally bet there plus the Kalshi, Polymarket, and ProphetX exchanges.
Online sports betting is legal in 30 US states and districts, and no two of them license the same set of books. The same moneyline can pay meaningfully more at one legal book than another, so the best price in Michigan is not the best price in New York. Each page below recomputes today's best odds across only that state's legal books.
Prediction market prices from Kalshi, Polymarket, and ProphetX are shown fee-adjusted, so they compare directly to sportsbook lines. No signup, no picks: math, not picks.
Live in a state without legal online betting? The federally regulated prediction markets on the Line Shop are still available in most of the country, and the free calculators and our graded pick record work anywhere.
