Full iGaming Regulation Cuts Offshore Market Share by More Than Half, Blask Analysis Finds
Comprehensive iGaming regulation significantly reduces offshore gambling activity in the United States, but does not eliminate it, according to Blask’s 2025 U.S. iGaming landscape analysis.
States that legalize both online casino and sports betting retain the majority of gambling value within regulated markets. In these environments, offshore market share falls to approximately 38% on average. By contrast, sports-betting-only states see offshore capture averaging around 74%, while unregulated states send virtually all online gambling activity offshore.
The findings highlight a structural reality: regulation improves channelization, but it is not a binary switch.
National Context: Offshore Still Dominates
Across all analyzed U.S. states, offshore platforms still account for roughly 79% of total online gambling value, compared to 21% captured by regulated domestic operators.
Despite more than a decade of legalization following the repeal of PASPA, offshore operators continue to dominate much of the market, particularly in jurisdictions without full iGaming frameworks.
Fully Regulated States: Majority Domestic Capture
States offering both online casino and sports betting demonstrate the strongest onshore retention.
- New Jersey captures approximately 73% of its gambling value domestically
- Michigan captures roughly 75% domestically
- Fully regulated states average about 62% domestic share
These markets show that access to a complete licensed product suite, including online casino, is critical for shifting player behavior away from unlicensed platforms.
Sports-Betting-Only States: Structural Leakage
The picture changes sharply in states that legalize sports betting but not online casino.
In these jurisdictions, offshore share averages around 74%, reflecting unmet demand for casino gaming.
Key examples:
- New York, the largest U.S. betting market by consumer expenditure, sees roughly 61% of value flow offshore
- Ohio shows an even wider gap, with offshore platforms capturing approximately 82% of market value
Without regulated slots and table games, players seeking a full gambling experience migrate to offshore sites.
Market Maturity Matters
Even within fully regulated states, time is an important factor.
Newer markets such as Rhode Island remain below the channelization tipping point, with offshore participation still exceeding domestic activity. This suggests that licensed operators require time to build brand trust, product depth, and customer loyalty before achieving optimal market capture.
Regulation establishes the framework, but channelization improves gradually as markets mature.
Regulation Is a Spectrum, Not a Switch
The U.S. experience demonstrates that comprehensive regulation can cut offshore participation by more than half compared to national averages. However, no state has fully eliminated offshore activity.
For policymakers and industry stakeholders, the implication is pragmatic: full-scope regulation meaningfully shifts economic value onshore, but expectations of total eradication are unrealistic.
The central policy question is no longer whether offshore markets exist, but how much revenue comprehensive regulation can reclaim for licensed operators and tax authorities.
