RUNREGULATED ONLINE GAMBLING MARKET HITS $5.9 TRILLION
The global online gambling black market continued its rapid expansion in 2025, underlining growing concerns among regulators and licensed operators about the scale of unregulated activity across international markets.
New industry estimates suggest the value of the unregulated online gambling sector reached approximately $5.9 trillion last year, representing another year of sustained growth and reinforcing fears that offshore operators are continuing to outpace many regulated markets.
The figures reflect a broader trend that has become increasingly visible across Europe, Latin America and parts of Asia, where stricter regulation, advertising restrictions and affordability measures have reshaped legal gambling environments. While many governments have introduced tighter controls aimed at strengthening consumer protection, industry stakeholders continue to warn that excessive friction within regulated markets risks driving players towards offshore alternatives.
The latest estimates focus exclusively on online gambling activity, including sports betting, casino gaming, poker, lotteries, crypto-linked gambling products and prediction markets operating outside local licensing systems. Analysts assessing the sector examined active operators targeting local consumers rather than simply accessible websites.
One of the report’s most striking conclusions is the sheer scale of unregulated activity compared to licensed markets. According to the estimates, offshore and unlicensed operators now account for the overwhelming majority of global online gambling revenue, leaving regulated operators with only a relatively small share of the total market.
This has intensified debate around whether current regulatory approaches are effectively balancing consumer protection with market competitiveness. Across several major jurisdictions, operators have repeatedly warned that increasingly restrictive frameworks may unintentionally strengthen the black market by making legal products less attractive or more difficult to access.
The UK has become one of the clearest examples of this wider discussion. Separate research published earlier this year indicated that offshore gambling activity in Britain has risen sharply in recent years, coinciding with tighter affordability checks, bonus restrictions and growing compliance demands placed on licensed operators.
At the same time, emerging product categories are creating additional challenges for regulators. Prediction markets, crypto gambling and decentralised betting products are increasingly operating in grey areas outside traditional gambling legislation. Regulatory treatment varies significantly between jurisdictions, with some countries moving to block such products while others are beginning to develop licensing structures around them.
Advertising is also becoming a central battleground. Analysts highlighted the growing relationship between illegal sports streaming and offshore gambling promotion, with unlicensed betting brands frequently appearing alongside pirated sports broadcasts. Major sporting events continue to provide significant visibility for these operators, particularly in markets where legal advertising restrictions have tightened.
Governments are responding in different ways. Some jurisdictions are introducing tougher advertising rules and stronger enforcement mechanisms, while others are focusing on public reporting tools and enhanced digital monitoring systems aimed at identifying illegal operators more quickly.
Australia, for example, has recently moved to strengthen restrictions around gambling advertising during live sports broadcasts, while politicians in the UK continue to debate broader limits on betting promotions and sponsorships. Elsewhere, countries such as Brazil and Ukraine have stepped up efforts to combat illegal gambling activity through platform blocking measures and tougher penalties.
Despite these efforts, many within the industry believe the black market issue is becoming increasingly globalised and technologically sophisticated. Offshore operators are often able to adapt quickly, using crypto payments, mirror websites, influencer marketing and international streaming platforms to bypass local restrictions.
The challenge facing regulators is no longer simply preventing illegal operators from entering a market. Increasingly, it is about ensuring regulated products remain competitive enough to keep consumers within licensed ecosystems.
As regulation tightens across multiple jurisdictions, the debate around channelisation, enforcement and consumer behaviour is likely to intensify further. For many in the industry, the continued growth of the offshore sector highlights a difficult reality: regulation alone is not enough if players ultimately find unlicensed alternatives easier, faster or more appealing to use.
