Legal betting in United States
Sports betting in United States is regulated by State gaming regulators (NJ DGE, NYSGC, PGCB, MGCB…); the legal betting age is 21. We only measure licensed operators — unlicensed books are excluded from every dataset on this site, so a missing name usually means a missing licence, not missing data. Licence status is re-checked when we refresh operator records, and a lapsed licence removes the operator from all rankings automatically.

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.
