Published statistics pages

US Sports Betting Statistics

Sports betting is legal in 40 US jurisdictions — 39 states plus the District of Columbia. (American Gaming Association, September 4, 2026.)

Covers legal jurisdictions, US commercial gaming revenue, and March Madness wagering.

Problem Gambling Statistics

An estimated 2.5 million US adults — about 1% — meet the criteria for a severe gambling problem in a given year, and another 5 to 8 million (2-3%) have mild or moderate problems. (National Council on Problem Gambling, 2026.)

Covers how many US adults are affected, the estimated annual social cost, and where to get help.

How these pages are built

Every card carries four things: the number, one line of context, a link to the primary source, and the date PMill verified it. PMill uses primary sources — the American Gaming Association, the National Council on Problem Gambling, and state gaming regulators — and does not publish a number it cannot link to a source.
