Illegal online gambling reaches $5.9tn globally in 2025, report estimates
A report cited in a press account estimates that unregulated online gambling generated $5.9tn worldwide in 2025, up from $5.7tn in 2024. A separate estimate puts illegal operators at 17% of Europe’s online gambling market in 2024, with €80.6bn in gross gaming revenue; the report cautions that measurement methods differ.
Different measurement methods caution operators and regulators against treating the global and European estimates as directly comparable.
