Churchill Downs Strikes Back Against Maine’s Tribal iGaming
Summary
Churchill Downs’ Oxford Casino has sued to block Maine’s recently enacted law that grants the state’s four federally recognised tribes exclusive rights to offer online casino gaming. The casino filed a complaint in the US District Court for the District of Maine on 23 January, seeking an injunction on grounds the measure is unconstitutional and unfairly excludes commercial operators.
Oxford Casino argues iGaming would hollow out brick-and-mortar revenues, threaten almost 400 jobs tied to the property and reduce state tax receipts. The operator cites its own contribution of more than $40 million in taxes in 2025 and industry figures that suggest an average 16% drop in traditional casino activity after online launches elsewhere. Because the law is tribal-only, commercial operators like Churchill Downs say they cannot compete by launching their own online offerings.
The law authorises online casino operations for these tribes: the Houlton Band of Maliseet Indians, Mi’kmaq Nation, Passamaquoddy Tribe and Penobscot Nation.
Key Points
- On 23 January Churchill Downs’ Oxford Casino filed suit in US District Court (District of Maine) seeking to block tribal-only iGaming legislation.
- Maine’s law permits the state’s four federally recognised tribes to offer online casino games to in-state players.
- Oxford claims iGaming will damage brick-and-mortar revenues, risk almost 400 jobs and reduce tax contributions — it paid over $40m in taxes in 2025.
- The casino cites an industry average 16% decline in traditional gaming after online casino launches in other states.
- Because the law restricts online licences to tribes, commercial operators say they are prevented from competing with their own online products.
Context and relevance
This dispute sits at the intersection of tribal sovereignty, state regulation and commercial operators’ market access. Several US states weigh tribal agreements differently when legalising iGaming; Maine’s tribal-first model is already provoking litigation that could set a legal precedent. Outcomes here will be watched by casinos, regulators, tribal governments and lawmakers elsewhere considering how to balance economic, legal and sovereignty issues when expanding online gambling.
Author’s take (punchy)
Churchill Downs isn’t just protecting one property — it’s pushing back against a policy choice that could become a template. If the court sides with Oxford, states that favour tribal-only online frameworks may face new hurdles. If the tribes prevail, commercial operators will have to rethink how they contest market access. Either way, this matter matters to the whole sector.
Why should I read this?
Short version: if you care about where US iGaming goes next — who gets licences, who pays taxes and who keeps jobs — this is the kind of fight that shapes the market. Churchill Downs suing over Maine’s tribal-only approach could ripple into other states and change how commercial casinos and tribes compete online.
