Offshore Casinos Retain Appeal in US Sports Betting Markets

The scale of offshore dominance in US online gambling is larger than partial regulatory data tends to suggest. Research from both Blask and Yield Sec, the latter compiling data on behalf of the Campaign for Fairer Gambling, confirms that unlicensed platforms command the clear majority of online gambling demand across the country.

In states where regulation covers only sports betting, that majority is significant, with licensed domestic operators regularly accounting for less than a third of total activity across the jurisdictions measured.

As it turns out, the unlicensed market is growing at a rate that outpaces regulated alternatives by a considerable margin, and the number of active illicit platforms operating domestically dwarfs the licensed operator count. Why?

Well, offshore platforms simply offer advantages that are difficult to match within the regulatory framework. Free from local taxation and state-level compliance requirements, unlicensed operators offer more generous promotional terms and a broader product range, conditions that attract and retain players that regulated platforms cannot directly compete for.

Where Regulation Makes a Difference

Regional data show the gap between partial and full regulatory frameworks. In states where online casinos and sports betting are legal, the platforms enjoy a larger share of local demand. In states limited to sports betting alone, offshore operators account for the remainder.

Maryland and Arizona are great examples. Both have achieved a greater domestic share than most betting-only states, though channelization there still falls short. Progress is visible, but affected by product limitations that apply across the category. Ohio sits at the other end of the divide, with unlicensed platforms dominating the state’s online gambling market by a wide margin. Per capita spending on illegal digital casinos is among the highest recorded nationally.

The Missing Piece

Licensed operators face a further disadvantage in audience reach. Offshore platforms maintain consistent visibility across major sporting events and mainstream media, while regulated operators work within advertising constraints that limit comparable exposure. Sweepstakes casino models, largely unregulated across multiple jurisdictions, add another layer of competition that enforcement has only partially addressed. Montana, Connecticut, and New York have each moved against sweepstakes operators, but the outlook remains uneven.

The data does not make a case against regulation. However, treating both product accessibility and enforcement as equal priorities may be the best step. Until policymakers act on both fronts, offshore platforms will continue to operate either in parallel or dominate in many cases.
