Unregulated Global Gambling Reached $5.9 Trillion in 2025

A groundbreaking report from Gaming Compliance International (GCI) reveals that the scale of unregulated online gambling reached a massive $5.9 trillion in global wagering value in 2025. This figure exceeds the GDP of almost every country, trailing only the United States and China. According to the report, GCI Online Gaming 2025: Global, published on 18 May 2026, unregulated operators now command a staggering 78% of global gross gaming revenue, leaving licensed, taxed operators with just 22%.

While unlicensed gambling has long competed with legal markets, this new analysis proves the gap is far wider than previously estimated. Total handle grew from $5.1 trillion in 2023 to $5.9 trillion in 2025, covering all wagers placed through international sports betting, casino, poker, crypto gambling, and lottery platforms worldwide. However, annual growth slowed to 4% in 2025, down from 12% in 2024. GCI Chief Executive Matt Holt emphasized that regulators are no longer facing a marginal challenge, but a dominant market force operating entirely outside the domestic regulated perimeter.

Crucially, the GCI report shifts away from the traditional view of a two-sector market (regulated vs. unregulated) to introduce a third, rapidly expanding category: "unacknowledged gambling." This sector includes platforms that replicate core gambling mechanics—such as stakes, chance, and rewards—but escape current regulatory definitions. Examples include prediction markets (such as financial or exchange betting), social casinos, sweepstakes platforms, and video game skins trading. 

GCI President Ismail Vali noted that everyday consumers do not distinguish between these categories, experiencing instead a singular, accessible marketplace where everything competes equally. This has created a "white noise marketplace", making it incredibly difficult for users to differentiate a licensed product from an unlicensed one.

GCI warns that current regulatory frameworks are fundamentally obsolete because they are designed for an outdated market structure. As the unacknowledged and unregulated sectors continue to expand, licensed operators face severe commercial losses, governments miss out on vital tax revenue, and consumer protections become nearly impossible to enforce. The report concludes that authorities must adapt to oversee the entire ecosystem—regulated, unregulated, and unacknowledged—or risk losing control of the industry entirely.
