Tribal Coalition Enters Legal Fight Over Event Contracts
A coalition of 27 federally recognized tribes and seven tribal associations has submitted an amicus brief in the ongoing legal dispute between prediction market platform Kalshi and the state of Maryland. The filing supports the state’s argument that Kalshi’s contracts violate existing gaming regulations by effectively functioning as illegal sports wagers.
This move echoes the coalition’s earlier intervention in a similar case involving New Jersey, highlighting widespread concern within tribal communities over the platform’s business model.
Concerns Over Sovereignty and Gaming Revenue
The brief includes support from prominent groups such as the Indian Gaming Association and the National Congress of American Indians. These organizations argue that Kalshi’s contracts, though regulated as financial instruments by the Commodity Futures Trading Commission (CFTC), mirror traditional sports betting and pose a direct threat to tribal gaming operations.
Tribal leaders emphasize that gaming revenue is crucial for funding public services and supporting self-governance. The brief warns that allowing Kalshi’s model to expand without scrutiny could jeopardize this vital source of tribal income.
Key Legal Conflict: CEA vs. IGRA
The central issue in the case is whether the Commodity Exchange Act (CEA), which regulates financial markets, overrides the Indian Gaming Regulatory Act (IGRA), which governs tribal gaming. Kalshi argues that it has legal authority under the CEA to self-certify its event contracts.
However, the tribes reject this claim, pointing to a “special rule” within the CEA that allows the CFTC to ban event contracts linked to gaming. They argue this provision shows Congress never intended for sports betting to fall under futures regulation. The brief underscores that Kalshi’s activities may also conflict with other federal laws like the UIGEA and the Wire Act.
Pushback from Kalshi
Kalshi has responded with a motion to exclude the tribes’ amicus brief, claiming the coalition lacks direct involvement in the Maryland case and brings no new legal arguments. The platform argues that responding to the brief so late in proceedings is unfair, given the short deadline for filing its supplemental response.
Kalshi also disputes the tribes’ interpretation of the “two-step” review process under the CFTC’s authority, asserting that the current legal framework supports their right to operate.
Background of the Maryland Dispute
The legal battle began after Maryland issued a cease-and-desist order, demanding Kalshi stop offering sports-related event contracts. In response, Kalshi filed a lawsuit to block the order, citing previous legal victories in Nevada and New Jersey. The matter now lies with the U.S. Court of Appeals for the Third Circuit, where several states and tribal groups have filed supporting briefs against Kalshi’s sports wagering model.
