RankingsTop Gambling Markets by Revenue
The world's largest regulated gambling markets, ranked by the most recent reported gross gaming revenue. Because reporting scope and currency differ, this is an ordering of headline figures — not a like-for-like total. Where scope differs (national aggregate vs. a single online market), it is stated in the table.
| # | Market | Reported revenue | Basis | Source |
|---|---|---|---|---|
| 1 | United States | $71.9B | Commercial GGR, 2024 | AGA |
| 2 | Europe (aggregate) | €123.4B (~$134B) | All-channel GGR, 2024 | EGBA/H2GC |
| 3 | Macau | $28.3B | Casino GGR, 2024 | Macau gov |
| 4 | Great Britain | £15.6B (~$20B) | GGY incl. lottery, 2023–24 | UKGC |
| 5 | Ontario (Canada) | C$3.2B (~$2.3B) | iGaming-only GGR, FY24–25 | iGaming Ontario |
Methodology. Ranked on latest full-period reported GGR from each market's primary authority. USD conversions are approximate and for ordering only. The US figure is commercial-only (US tribal gaming, reported separately, would add a comparable sum); Ontario is a single sub-national online market included to show scale. This ranks markets, not operators.
