GCI Report: Unregulated Online Gambling Reached $5.9 Trillion in 2025 Wagers — 78% of Global iGaming Market Operating Without a Licence

$5.9 Trillion and Growing: The Scale of the World's Unregulated Gambling Market

Gaming Compliance International published what may be the most cited single statistic in the global iGaming industry for 2026 on May 18: the global unregulated online gambling market processed approximately $5.9 trillion in total wagers during 2025. That figure positions the unregulated market as the world's third-largest economy by this metric — behind only the United States and China.

The report, GCI Online Gaming 2025: Global, represents the most comprehensive attempt yet to quantify the competitive environment that regulated iGaming markets operate within.

Understanding the $5.9 Trillion Figure

GCI uses "global wagering value" — total wagers placed, equivalent to gross handle — rather than gross gaming revenue (GGR). This distinction is critical for interpreting the figure. Handle and GGR are fundamentally different metrics: handle measures total money wagered, while GGR measures what operators retain after paying winning bets. The same funds can cycle through multiple bets sequentially, inflating handle relative to GGR.

The unlicensed market's GGR equivalent is not provided at the headline $5.9 trillion level, but GCI's analysis of the regulated versus unregulated GGR split is equally striking: 78% of total global online gaming gross gaming revenue was generated by operators without a licence in 2025, with only 22% flowing through licensed, taxed, and consumer-protected frameworks.

Growth Trajectory

The $5.9 trillion figure represents sequential growth: $5.1 trillion in 2023, $5.7 trillion in 2024, and $5.9 trillion in 2025. Growth is decelerating slightly in absolute terms, which GCI attributes to increased regulatory action in key markets rather than organic slowdown in unlicensed operator activity.

The Three-Sector Model

Perhaps the most conceptually significant contribution of the GCI report is its three-sector model of the global online gambling market: Regulated (licensed, taxed, consumer-protected), Unregulated (explicitly illegal offshore operators), and Unacknowledged — the grey sector comprising sweepstakes casinos, social casinos, and prediction markets that occupy a legal grey zone and are not classified as gambling by operators but function as gambling substitutes for consumers.

Why It Matters

The $5.9 trillion handle figure underscores the scale of what licensed operators, regulators, and responsible gambling bodies are competing against. For iGaming operators and their B2B suppliers, the GCI report provides the most comprehensive single data source on the competitive landscape that regulated markets face from unlicensed alternatives. It also provides critical context for the sweepstakes crackdown debates in Illinois, Minnesota, and Nevada: regulators who argue that enforcement is commercially motivated are confronted with data showing a $5.9 trillion black market that demonstrably dwarfs the regulated sector.
