Maine's Wabanaki Nations Defend Exclusive Online Gaming Law

Maine's four federally recognized tribes are now positioned to become the exclusive operators of online casino gaming in the state, the result of a hard-won statute that took effect in early 2026 and an unfolding court fight that will test how far tribal economic sovereignty extends in the one state where it has long been most constrained.

Under LD 1164, which became law after Governor Janet Mills declined to veto it in January 2026, the Passamaquoddy Tribe, the Penobscot Nation, the Houlton Band of Maliseet Indians and the Mi'kmaq Nation hold exclusive rights to operate internet gaming in Maine. The framework lets each nation seek a license to run online slots and table games, with the proceeds intended to flow directly into tribal governments that have historically been shut out of the casino economy enjoyed by tribes elsewhere in the country.

Mills met with the elected chiefs of the Wabanaki Nations in the fall of 2025 before allowing the measure to advance. According to the governor, each chief spoke about the bill as a source of life-changing revenue and a form of economic sovereignty — language that framed the law less as a gambling expansion than as a long-delayed act of restitution.

Why Maine is different

For most tribes, the Indian Gaming Regulatory Act of 1988 is the controlling framework, and our legal guide to IGRA and Class III gaming walks through how tribal-state compacts are typically negotiated. Maine is the exception. The 1980 Maine Indian Claims Settlement Act, which resolved sweeping land claims, also subjected the Wabanaki Nations to state law in ways that have repeatedly blocked them from opening the kind of brick-and-mortar casinos that fund schools, housing and health care for tribes in Oklahoma, California and Connecticut.

That history is the backdrop for why the iGaming law matters out of proportion to the size of the market. Maine is small, but exclusive online gaming rights represent one of the most significant economic concessions the state has extended to the Wabanaki Nations in decades. Tribal leaders have been careful to describe the measure as a recurring revenue stream they control rather than one mediated through the state — a distinction that sits at the heart of the broader sovereignty debate playing out in Augusta.

Even supporters caution that exclusivity is not a cure-all. Reporting in the months since the law passed has noted that economic disparities across the Wabanaki communities persist, and that a single revenue channel, however symbolically important, will not close gaps built up over generations. The licensing structure still has to be stood up before any wager is accepted.

The Churchill Downs challenge

The exclusivity did not go unchallenged. In January 2026, Churchill Downs Incorporated, which operates commercial gaming and historical horse racing interests, sued the state, arguing that handing online gaming solely to the tribes violates provisions of the U.S. and Maine constitutions. The company's complaint frames the carve-out as impermissible preferential treatment. The tribes and their allies counter that the arrangement reflects the federal government's long-standing recognition of tribes as distinct political sovereigns rather than a racial classification — a legal distinction the courts have upheld in other contexts.

In April 2026, the four Wabanaki Nations filed a motion to intervene in the litigation, and the district court granted it — a procedural win that lets the tribes defend the law directly rather than rely on the state's lawyers alone. The Native American Rights Fund and other advocates have lined up behind the nations, casting the case as a referendum on whether tribal economic development can withstand a well-financed commercial-operator challenge.

The dispute echoes a pattern seen elsewhere: where tribes secure exclusive digital gaming rights, deep-pocketed commercial operators frequently turn to the courts. How Maine's case resolves could shape the negotiating leverage of tribes in other small states weighing similar arrangements.

What to watch next

Several questions remain open. Licensing rules and a regulatory structure must be finalized before any Wabanaki-branded online casino accepts a bet, and the litigation could delay or reshape the rollout. Observers will also watch whether the exclusivity model survives appeal, because a ruling against the tribes would reverberate well beyond Maine. Other small states with limited commercial gaming have watched the Maine experiment closely, and a decision upholding tribal exclusivity could embolden similar proposals where a single, well-regulated operator is easier to stand up than a competitive commercial market.

The Maine fight fits a national story about how tribes are defending exclusivity against new digital competitors. It rhymes with our coverage of the Seminole Tribe's statewide mobile gaming compact in Florida, where courts ultimately left a tribal model intact.

For now, Maine's small but symbolically outsized experiment is among the more closely watched developments in Indian Country this year — a test of whether a state can make tribal sovereignty pay, and whether the courts will let it stand.
