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.
Another report, commisisoned by Euromat, estimates that Europe’s black market has sustained a compound annual growth rate of 18% between 2019 and 2026, and will be worth up to €13 billion by the end of the year.

According to The Intercept, some content even uses expressions like “leaving the CLT [Brazilian labour law]” and “your dream income” to promote this type of activity. There are also screenshots of alleged user earnings and posts that present gambling as a kind of investment.
