Billions in tax revenue would be generated by expanding sports betting legalization

Billions of tax revenue would be generated if all 50 states in the US made sports betting legal, a report by the Tax Foundation claims.

If all states established statewide gambling markets, the Tax Foundation estimates that gross gaming revenue (GGR) would increase by $15.6 billion per year.

This figure is more than double what is being reported right now, and legal sports betting in all states would generate $1.6 billion annually in tax revenue, assuming a 10% GGR tax.

Despite most states legalizing sports wagering in some form, only 30 states allow bettors to utilize online betting platforms.

States are shaded from light to dark blue to indicate lower to higher estimated annual tax revenue, ranging from about  million to nearly 0 million. California, Texas, and Florida are the darkest, representing the largest potential gains. The map headline states that nationwide legalization would increase annual tax revenues by .6 billion, with data attributed to the Tax Foundation.
A Tax Foundation report estimates that legalizing sports betting in all 50 U.S. states could generate $1.6 billion in annual tax revenue, with the biggest gains coming from California, Texas, and Florida.

Should legalization occur in all states, the biggest tax revenue gains would occur in California ($570 million), Texas ($326 million) and Florida ($199 million), which would contribute significantly to the economy.

Could we see sports betting legalized in all states in the future?

Sports betting is still unavailable across 11 US states

Missouri has become the latest state to legalize sports betting, with the first state-regulated sportsbooks going live towards the end of last year.

States permitting online betting are shaded in green, with darker green indicating higher tax rates ranging from about 6.75% to 51%, while states without statewide online betting are shown in gray. The map title notes that 30 states and DC allow statewide online sports betting, with data sourced from state statutes and LegalSportsReport.
As of August 2025, 30 U.S. states and Washington, DC allow statewide online sports betting, with tax rates varying widely—from under 7% in some states to over 50% in others—according to the Tax Foundation.

That now leaves 11 states where sports betting is not legal: South Carolina, Hawaii, Georgia, Alabama, Alaska, California, Texas, Oklahoma, Minnesota, Utah and Idaho.

While California and Texas would be the two biggest generators of tax revenue should legalized sports betting be introduced, some of the smaller states would still generate millions.

Hawaii, for example, would generate $11 million per year in tax revenue, despite a small population of adults within the state.

Idaho also has a smaller population of adults compared to other states, yet it would likely generate around $13 million per year in tax revenue.

Even Alaska, with a third of the population confined to rural areas, would be able to generate $6 million in tax revenue, despite the state having no professional sports teams in the state.

Of those 11 states, only Georgia has an active legislature regarding the legalization of sports betting, suggesting there is plenty of work to do to ensure all 50 states could benefit from the extra tax revenue.
