The timing is significant. The illegal gambling market is attracting growing attention from regulators and the wider industry, while estimates of its size vary considerably depending on definitions and methodology.

A recent Fincord Intelligence report highlighted by the Betting and Gaming Council estimated that illegal online gambling generated around $50 billion in gross revenue globally in 2025. It estimated that around 5,000 operator structures were using more than 15,000 websites and apps.
