Churchill Downs files lawsuit challenging Maine’s tribal iGaming monopoly

Summary

Oxford Casino, owned by Churchill Downs Incorporated and operated via BB Development, has filed a federal lawsuit in the US District Court for the District of Maine (filed 23 January 2026). The complaint challenges Maine’s new iGaming law — effective 11 January 2026 — which grants exclusive online casino rights to the state’s four federally recognised tribes. The suit argues the law violates equal protection provisions of both the US and Maine constitutions and the Commerce Clause by discriminating against out-of-state businesses.

Key Points

Oxford Casino (Churchill Downs) filed suit on 23 January 2026 seeking a declaration the law is unconstitutional and an injunction blocking enforcement.
The law limits iGaming licences to four Maine federally recognised tribes: the Houlton Band of Maliseet Indians, the Mi’kmaq Nation, the Passamaquoddy tribe and the Penobscot Nation.
Oxford employs 364 people in Maine and paid more than $40m in state taxes in 2025; plaintiffs warn of local economic harm.
The complaint cites research estimating roughly 378 jobs lost, $22m in lost labour income and $60m in lost value added if iGaming proceeds under the current exclusivity model.
Plaintiffs state land-based casino revenue typically falls ~16% after iGaming introduction and argue the statute unlawfully uses race-based preferences in licensing.
Oxford says it would apply for an iGaming licence but is ineligible because the law restricts licences and transfers to businesses wholly owned by the listed tribes.
The National Association Against iGaming is also opposing the law and aims to pursue a public referendum to block it.

Content summary

The complaint contends Maine’s iGaming statute improperly discriminates against non-tribal and out-of-state operators, denying them the opportunity to compete and thereby harming local businesses that have invested in the state. Oxford seeks court relief to open the licence process to all qualified applicants rather than reserving it exclusively for the four recognised tribes. The plaintiffs frame the issue as both a constitutional equal-protection and interstate-commerce problem.

Context and relevance

Maine is the eighth US state to legalise iGaming with this law, the first new market since Rhode Island in 2023. The dispute is significant for the US gambling sector because it tests whether states can confine online casino rights to specific tribal entities without running afoul of constitutional protections and Commerce Clause limits. The case could influence how other states structure iGaming licences and tribal exclusivity arrangements.

Why should I read this?

Because this is the kind of legal kerfuffle that can reshape market access. If you follow US iGaming, regulation or commercial strategy, the outcome will matter — it could either entrench tribal-only online markets or open the door for racially neutral, competitive licensing. Short version: grab the details now so you’re not blindsided later.
