How we rank

Our United States ranking is computed, not negotiated. We sample live odds continuously across every tracked bookmaker and measure three things per operator: how often it holds the best available price, its average margin on core markets, and how many markets it actually prices per event. Those measurements drive the largest share of the score; licence status, payment coverage and payout latency fill in the rest. Commercial deals never move a position.

US sports betting is regulated state by state. An operator licensed in New Jersey is not automatically legal in another state — availability, minimum age and rules depend on your state regulator.
