US-regulated casinos and sportsbooks
Which state regulators license which brand, for sports betting and for online casino, read off each regulator's own published list. 18 brands across 28 states. These are regulated US operators, not the offshore crypto casinos covered elsewhere on the site — different licences, different rules, and they only take you if you are physically in a state that allows it.
Counts are states whose regulator names the brand on its own published list, not states it is live in — a few lists lag a rebrand, and each brand page says so where it applies. 68 further listings are venue names, licence-holding companies or B2B platform suppliers rather than brands you can sign up to; they stay on their state pages rather than being guessed into a brand here.
