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.
Other estimates are considerably higher, illustrating how difficult the market is to measure. As an example, separate research from Gaming Compliance International put the value of unregulated online gambling at $5.9 trillion in wagering value in 2025, while estimating that unregulated operators accounted for 78% of global online gaming GGR.
