Americans wagered $673.6 billion with illegal and unregulated gambling operators in 2025. That figure—published by the American Gaming Association itself, not by offshore industry advocates—means that nearly one-third of all US gaming volume flows outside the regulated market. The offshore sector generates an estimated $53.9 billion in annual revenue from American players alone.
The domestic industry’s response has been to lobby for enforcement. The more interesting question is why the capital is leaving in the first place.
The Tax Squeeze
US commercial gaming revenue hit a record $78.72 billion in 2025, generating $18.09 billion in state gaming taxes—a 15.1% increase over the prior year. On the surface, the numbers suggest a thriving industry. Underneath, they reveal a system that is taxing its operators toward structural fragility.
New York levies a 51% tax on sports betting revenue. New Hampshire and Rhode Island match that rate. Illinois implemented a graduated structure in 2024 that peaks at 40%. These are not marginal tax rates applied to net profit—they are applied directly to gross gaming revenue, before the operator deducts marketing costs, platform maintenance, customer acquisition, or overhead.
The downstream effects are predictable. When an operator retains less than half of every revenue dollar before expenses, the economics dictate narrower odds, tighter betting limits, slower payouts, and reduced promotional incentives. For recreational bettors, this manifests as a slightly worse experience. For high-volume players—the segment that generates disproportionate handle—it creates a measurable economic incentive to move offshore, where operators face tax burdens between 0% and 15% and pass the margin differential directly to the player.
Then came the federal gambling loss deduction cap. Effective January 1, 2026, US gamblers can now deduct only 90% of their losses against winnings—down from the historical 100%. For a professional or semi-professional player reporting $500,000 in annual winnings and $480,000 in losses, that 10% haircut translates to a $2,400 increase in federal tax liability. For someone operating at the million-dollar level, the number doubles.
The legislation was designed to generate revenue. What it also generates is a marginal incentive for the exact demographic—high-net-worth, high-volume players—that regulated operators can least afford to lose.
Where the Liquidity Flows
International gaming jurisdictions have spent the last decade building infrastructure specifically designed to absorb this capital. The licensing landscape operates in distinct tiers.
Curaçao, historically the default offshore jurisdiction, has undergone significant regulatory modernization. Its new framework—implemented in phases through 2025—requires individual operator licenses, stricter AML compliance, and segregated player funds. The jurisdiction has evolved from a loosely regulated haven into what industry analysts now classify as a mid-tier licensing authority, alongside Kahnawake.
Below that tier, jurisdictions like Anjouan and Costa Rica offer entry-level licensing at substantially lower cost. The Anjouan Offshore Finance Authority issues gaming licenses for approximately €17,000—a fraction of what Curaçao or Malta requires. The trade-off is reduced regulatory prestige, but for operators targeting specific player demographics, the licensing cost differential allows for significantly more competitive player-facing economics.
At the top tier, Malta and the Isle of Man maintain the most rigorous compliance standards in the offshore sector. When analyzing the capital reserves of international operators accepting US liquidity, the structural advantage becomes apparent: operators in these jurisdictions maintain cold-storage reserves, provably fair gaming systems, and payout processing speeds that state-regulated platforms—constrained by banking intermediaries and withdrawal verification requirements—cannot match without regulatory reform.
The operational differences are not trivial. A domestic operator processing a withdrawal through ACH or wire transfer typically settles in 3–5 business days. An international operator settling through cryptocurrency processes the same transaction in minutes. For a player withdrawing $50,000, the difference between immediate settlement and a five-day hold—during which the funds remain exposed to reversal, additional verification requests, or compliance holds—is not a minor convenience issue. It is a liquidity management decision.
The Regulatory Arbitrage Calculation
The conventional framing presents offshore gaming as an enforcement problem—illegal operators stealing market share from licensed businesses. The financial data suggests a more nuanced dynamic.
Consider the economic structure of domestic versus international casino operations. A New York-licensed sports betting operator faces: 51% GGR tax, federal corporate income tax, state corporate income tax, licensing fees, mandatory responsible gambling expenditures, and compliance costs associated with operating under multiple state-level regulatory frameworks simultaneously. After expenses, net margins in high-tax states compress to single digits.
An internationally licensed operator faces: a flat licensing fee (often annual), corporate tax in its domicile jurisdiction (frequently 0–15%), and compliance costs proportional to its licensing tier. Net margins routinely exceed 30%.
That margin differential does not disappear. It gets recycled into the player experience: better odds, higher betting limits, faster withdrawals, larger bonuses, and—critically—the ability to offer products that US regulators have restricted or prohibited entirely. Certain bet types, casino game variants, and wagering structures that are commonplace in international markets remain unavailable domestically due to state-level regulatory fragmentation.
For the investor analyzing digital versus traditional casino economics, the offshore market represents a parallel industry with fundamentally different cost structures—one that currently captures nearly a third of total US gaming volume and has been growing faster than the regulated market for four consecutive years.
The 2026 Inflection Point
Three simultaneous pressures are converging on the US regulated gaming market this year.
First, the 90% loss deduction cap took effect on January 1. Tax season will deliver the first wave of consequences, as high-volume players calculate their increased liability and adjust behavior accordingly. The American Gaming Association has already lobbied Congress to reverse the provision—an implicit acknowledgment that it drives handle offshore.
Second, state tax rates continue to climb. The Tax Foundation’s 2025 analysis documented a clear trend: states that legalized sports betting more recently have imposed higher tax rates than early adopters, treating gaming revenue as a fiscal resource to be maximized rather than an industry to be cultivated.
Third, international jurisdictions are simultaneously improving their compliance standards. Curaçao’s regulatory overhaul, Anjouan’s updated AML requirements, and the broader trend toward transparent licensing frameworks have narrowed the credibility gap between offshore and domestic operators. The narrative that offshore equals unregulated is increasingly outdated.
What the Numbers Actually Say
The $673.6 billion in unregulated US gaming volume is not an anomaly. It is a rational market response to a regulatory framework that has prioritized tax extraction over player retention. The largest gambling stocks derive their valuations from the assumption that domestic market share will expand as more states legalize. That assumption holds only if the regulatory and tax environment gives players a reason to stay.
The capital is not fleeing because offshore operators are marketing aggressively. It is fleeing because the arithmetic favors it. A 51% GGR tax, a 90% loss deduction cap, multi-day withdrawal processing, and a fragmented regulatory landscape that prevents interstate liquidity pooling create a structural disadvantage that no amount of enforcement can fully offset.
The question facing US gaming regulators is not how to stop capital flight. It is whether the current tax and regulatory framework makes capital flight inevitable—and at what point the $18.09 billion in annual gaming tax revenue begins to contract as the players generating it relocate their wallets to jurisdictions that offer better terms.
