US Sports Betting State-by-State

There is no single US sports-betting market. Since PASPA fell, every state sets its own rules, taxes and access model. Here is how to read the map.

The United States does not have one sports-betting market. It has a patchwork that grows state by state, and understanding it means understanding why each state looks different from its neighbour.

Why the map is fragmented

For decades a federal law, PASPA, effectively blocked state-authorised sports betting outside a handful of exceptions. In 2018 the Supreme Court struck PASPA down in Murphy v. NCAA, ruling that the decision belonged to the states. Since then each state has legislated for itself, which is why rules, taxes and even whether betting is legal at all vary so widely.

The categories to sort states into

When you assess a state, place it in one of these buckets:

Full mobile and retail: online sportsbooks plus physical books. These are the commercially important markets.
Retail only: legal betting, but restricted to in-person wagering at casinos or licensed venues, which caps the addressable market sharply.
Not yet legal: no authorised sports betting, sometimes for constitutional reasons that require a voter referendum to change.
Tribal-led: markets shaped by tribal gaming compacts, where the exclusive right to offer betting may sit with tribes.

What varies between states

Tax rate and base. This is the single biggest driver of profitability. Some states apply a modest rate on GGR; others apply a very high rate on mobile revenue, which changes how much can be spent on marketing and pricing.
Market access. How many operators, or "skins", a state permits, and how they qualify, decides how competitive the market is.
Product scope. States differ on in-play betting, betting on in-state college teams, and player-prop restrictions.
Licensing and fees. Application costs and renewal terms vary and feed straight into the cost of entry.

The tribal dimension

Tribal gaming adds real complexity. In several large states the right to offer betting is tied to compacts negotiated between tribes and the state, and disputes over those compacts have delayed or reshaped launches. Never assume a state's market structure without checking who holds the rights.

How to read a new state

Confirm whether mobile is legal or the market is retail-only.
Find the tax rate and, crucially, the base it applies to.
Count the available licences and the qualification route.
Check product restrictions that affect handle, especially in-play and college betting.
Identify the regulator and read its rules directly.

Because states legalise on their own timelines, the list of live markets keeps changing. Confirm a state's current status with its regulator rather than relying on a snapshot.

Regulation, tax and market figures move quickly, sometimes mid-year. Where this guide gives a number, treat it as a starting point and confirm the current position with the named primary source before you rely on it.
