The global unregulated gambling market has grown to $5.9 trillion in wagering value, according to a new report from Gaming Compliance International. That figure would make it the third largest economy in the world, trailing only the United States and China.
GCI released the findings this week, describing the scale of unlicensed online gambling as a “multi-trillion-dollar economy operating outside oversight.” The report covers sports betting, casino sites, crypto gambling, and prediction markets.
Unregulated Operators Now Control Most of the Market
According to GCI, 78% of gross gaming revenue worldwide now goes to unregulated operators. The organization says this makes unregulated gambling the largest form of cybercrime on the planet.
Matt Holt, CEO of GCI, said the industry is operating largely beyond the reach of regulators. “At $5.9 trillion in wagering value, unregulated online gambling is one of the largest economic systems in the world,” Holt stated.
The report also identifies a new layer in the gambling market. Beyond the traditional split between regulated and unregulated, GCI now tracks what it calls “unacknowledged gambling.”
This third category includes social casinos, sweepstakes platforms, skins trading, and contests hosted on apps like TikTok. These products often avoid being classified as gambling despite functioning in similar ways.
Ismail Vali, President of GCI, said this third sector is “accelerating consumer confusion, unregulated growth, and regulatory complexity at scale.” He described a three-sector marketplace now present in every jurisdiction.
Illegal sports streaming has become a major pipeline for unregulated gambling. GCI found that during 2024 and 2025, unregulated gambling ads appeared on more than 80% of illegal sports streams in the US and UK.
These streams serve as recruitment tools, pulling viewers toward unlicensed betting platforms. The link between pirated sports content and offshore gambling continues to grow.
Holt warned that regulators are not dealing with a small problem. “The majority of activity is occurring beyond the regulated perimeter,” he said.
Governments Push Back With New Rules
The GCI report follows recent data from H2 Capital showing the UK’s offshore gambling market surged to £16.6 billion in 2025. That figure was up from £5 billion in 2019, a jump of more than 230%.
The sharp rise has put pressure on regulators around the world to take stronger action.
Australia has responded with a national reform package following the Murphy Report. The country introduced a ban on online keno and restricted wagering ads during live sports on free-to-air television between 6 am and 8:30 pm.
Ukraine has taken a different approach. Its regulator, PlayCity, launched an online tool allowing the public to report illegal gambling ads directly.
Ukraine has also set its administrative fine for illegal gambling advertising violations at UAH5.19 million, roughly $117 million, for 2026.
The GCI report paints a picture of an industry that has outpaced the ability of governments to regulate it. With the unacknowledged gambling category continuing to expand, the challenge for regulators is growing more complex.
As of 2026, Ukraine’s $117 million fine for illegal gambling ads stands as one of the steepest penalties any country has introduced to combat the black market.
