Key Takeaways
Contents
- Offshore gambling platforms account for just 38% of activity in comprehensively regulated states, versus 79% across the nation
- States offering both iCasino and sports wagering keep approximately 62% of gambling revenue within regulated markets
- Sports-betting-only jurisdictions surrender roughly 74% of total gambling activity to offshore operators
- Michigan and New Jersey demonstrate the strongest domestic market retention at over 70%
- While no jurisdiction has completely eliminated offshore activity, comprehensive regulation dramatically reduces it
For more than ten years, American states have been gradually opening their doors to legalized online gambling. Despite this expansion, offshore operators continue to dominate the landscape. Fresh insights from Blask’s 2025 comprehensive U.S. iGaming market study reveal the actual effectiveness of state-level regulation.
When examining all surveyed U.S. jurisdictions, offshore platforms command approximately 79% of the market. This leaves merely 21% of total online gambling activity flowing through legally sanctioned, domestic channels.
The effectiveness of regulation varies dramatically based on what each state has chosen to legalize. Jurisdictions that have embraced both internet casino gaming and sports wagering demonstrate significantly superior performance in retaining gambling activity within state borders.
Comprehensive Regulation Yields Strongest Results
New Jersey successfully captures approximately 73% of its online gambling marketplace through licensed domestic operators. Michigan performs even more impressively, keeping roughly 75% of total market activity within its regulated framework.
When averaged together, comprehensively regulated jurisdictions retain around 62% of gambling expenditure domestically. This pushes offshore platform market share down to roughly 38%.
These jurisdictions provide consumers with complete legal access to gambling options, including slots, traditional casino table games, and comprehensive sports wagering. This complete offering emerges as the critical element in redirecting users from unlicensed offshore operations.
The disparity with sports-wagering-only states proves striking. Jurisdictions that have authorized sports betting while excluding online casino offerings average approximately 74% offshore market share.
New York, despite being the nation’s largest market measured by consumer betting expenditure, watches roughly 61% of total value migrate to offshore platforms. Ohio faces an even more severe challenge, with 82% of activity flowing to unlicensed international sites.
The explanation is uncomplicated. Residents seeking slot machines or casino table games in these limited-regulation states face zero legal alternatives. Consequently, they migrate to offshore platforms to access desired products.
Legalizing sports betting in isolation fails to address the complete spectrum of consumer demand for internet gambling. Without casino gaming products, states effectively abandon substantial market segments to unlicensed international operators.
Market Maturity Influences Domestic Retention
Market maturity plays a significant role. Rhode Island, among the most recently regulated comprehensive markets, continues experiencing higher offshore activity than domestic participation. Its offshore share remains above 50%.
This pattern indicates that even with optimal regulatory structures in place, licensed operators require time to establish consumer confidence and develop robust product offerings. Market channelization toward legal options doesn’t occur overnight.
New Jersey and Michigan have benefited from years of market development. That operational history clearly reflects in their superior performance metrics.
The research presents unambiguous guidance for state legislators and regulators. Comprehensive regulatory frameworks encompassing both casino gaming and sports wagering reduce offshore activity by over half when compared to national averages.
However, even the best regulation doesn’t completely eliminate offshore participation. Zero U.S. jurisdictions have achieved complete elimination of unlicensed gambling activity.
The Blask research characterizes regulation effectiveness as existing along a continuum rather than functioning as a binary outcome. Legalization establishes favorable conditions for domestic market capture, but complete eradication of offshore gambling remains an unrealistic goal.
For state governments still deliberating their regulatory approach, the evidence strongly suggests that sports-betting-only frameworks leave the majority of potential market value unaddressed. Maximum domestic market capture requires offering consumers a complete range of regulated gambling products.
Rhode Island’s initial performance demonstrates that newly regulated markets require patience and persistence. Even with comprehensive legal frameworks established, building dominant domestic market share represents a gradual evolution dependent on operator infrastructure investment and sustained consumer confidence development.
