Exclusivity Clauses in Tribal Compacts: When Payments Can Stop

Behind almost every revenue-sharing payment a tribe makes to a state sits a promise about competition. In tribal-state compacts, exclusivity clauses define what the state has agreed not to authorize, and payment obligations are often written to depend on that promise. When a state expands its gambling market, or when a new product enters it, those clauses determine whether a tribe must keep paying, may reduce payments, or may stop altogether. This explainer covers how exclusivity clauses work, why they are tied to revenue sharing, and what happens when a tribe believes exclusivity has been breached.

Why exclusivity and payments are linked

The link begins with federal law. The Indian Gaming Regulatory Act permits tribes to conduct Class III gaming, such as slot machines and table games, only under a compact negotiated with the state. IGRA also bars states from taxing tribal gaming revenue. That prohibition means a state cannot simply impose a tax as the price of a compact. Payments to a state or to a state fund are permissible when they are part of a bargain in which the tribe receives something of real value in return, commonly called a meaningful concession. Exclusivity, meaning a defined right to offer certain games that others in the state cannot, is the classic example.

In practice, then, the payment is the tribe's side of an exchange and exclusivity is the state's side. Our overview of how revenue sharing works in a tribal-state compact covers the payment structures in more detail, and our explainer on how tribal gaming exclusivity works covers the exclusivity side.

What exclusivity clauses typically say

Compacts differ, so no single description fits all of them, but several features recur. A clause usually identifies the games or activities covered, such as electronic gaming devices or table games, and states that the tribe has the exclusive right to offer them in a defined geography. It may describe the exceptions, for example existing lottery products or pari-mutuel wagering that the state already authorized before the compact was signed. It also often addresses what happens if the state later authorizes competing gaming.

That last provision is the important one. Some compacts specify that payments are reduced, suspended, or eliminated if the state authorizes new forms of covered gaming. Others are silent or ambiguous, leaving the question to negotiation, arbitration, or litigation. The difference in drafting can be decisive, since a tribe with an express suspension right stands in a very different position from one that must argue the point in court.

The words that define what counts as competing gaming are usually where disputes begin. A product the compact did not anticipate can fall into a gap between the clauses.

How the definition problem arises

Exclusivity clauses are written at a moment in time. Compacts signed decades ago described the gaming products of that era, and later developments, including state lotteries moving online, legal sports betting, internet casino games, historical horse racing, and now prediction markets, may not fit neatly into the original categories. A state may argue that a new product is not covered gaming under the compact's definitions, while a tribe may argue that the product competes directly with what it was promised to protect.

Michigan offers a current illustration. Reporting by Casino.org shows that payments from Michigan tribes to the state's Strategic Fund fell 71 percent between 2022 and 2025, with tribes pointing to expansions such as online lottery, online casinos and sports betting, and horse racing as erosion of the exclusivity they were promised. We cover the details in our news report on the decline in Michigan tribal payments. The case shows how the same underlying question, whether the market has been opened beyond what the compact allows, can lead multiple tribes to similar conclusions over several years.

What happens when a tribe believes exclusivity was breached

The available responses generally fall into a few categories. A tribe may negotiate with the state, seeking an amendment that adjusts the payment formula or clarifies the exclusivity language. It may invoke the compact's dispute-resolution procedure, which in some compacts provides for arbitration or other structured processes. It may go to court, although sovereign immunity issues can complicate suits, and state and tribal immunity affect who can sue whom and where. And in some cases, a tribe may take the step of reducing or withholding payments, which shifts the burden to the state to challenge that decision. Our explainer on dispute resolution and arbitration in tribal-state compacts describes how those processes typically operate.

Each option carries risk. Withholding payments can invite enforcement action or a claim that the tribe has breached the compact, particularly if the compact does not clearly authorize suspension. Litigation can be slow and expensive. Negotiation depends on both parties being willing to reopen terms. Because outcomes hinge on precise language, tribes and states alike tend to rely heavily on counsel when interpreting these clauses.

Why it matters beyond one state

Exclusivity clauses shape the economics of tribal gaming and state budgets alike. States that receive payments have an interest in maintaining the compact bargain, while also weighing the tax revenue that new forms of gaming can produce. Tribes that depend on gaming revenue for government services have an interest in protecting the market their compacts describe. Compacts negotiated or renegotiated in the coming years will likely address these questions more explicitly, with clearer definitions of covered gaming and clearer consequences when the market changes.
