Ho-Chunk Nation Challenges Kalshi Over Marketing Practices

The Ho-Chunk Nation has recently moved to amend its legal complaint against Kalshi following a court decision that declined to consider the tribe’s claims under the Lanham Act. This development continues an ongoing legal confrontation between the tribe and the prediction market company.

Background: Opposition to Prediction Markets in Wisconsin

The Ho-Chunk Nation has been a vocal critic of prediction markets operating in Wisconsin, voicing concerns about potential threats to tribal sovereignty. The tribe contends that Kalshi employs misleading marketing tactics and challenges the classification of Kalshi’s products, insisting they should be identified as sports betting. Kalshi, on the other hand, firmly maintains that its offerings do not constitute gambling or betting but are instead regulated event contracts.

Dispute Over Legality on Tribal Land

The tribe argues that Kalshi has misrepresented the legality of its products on tribal territory. Since prediction markets fall under the jurisdiction of the Commodity Futures Trading Commission (CFTC) and are not classified as betting, Kalshi claims it can legally operate on tribal lands, bypassing restrictions that typically apply to traditional sportsbooks. However, the Indian Gaming Regulatory Act (IGRA) reserves the authority for tribes to control which gaming activities can take place on their lands, a point emphasized by the Ho-Chunk Nation in their complaint.

Court Ruling and Complaint Amendment

Initially, Kalshi attempted to dismiss the lawsuit centered on deceptive advertising. In May, a federal judge allowed the lawsuit to proceed but dismissed the tribe’s claims under the Lanham Act and the Racketeer Influenced and Corrupt Organizations Act, reasoning that there was insufficient precedent to deem Kalshi’s marketing false.

In response, the Ho-Chunk Nation has updated its complaint, refocusing on the provisions of the IGRA. The amended legal filing stresses that the IGRA clearly grants tribes the right to determine permissible Class III gaming activities on their lands.

Tribe’s Position on Kalshi’s “50 States Legal” Claim

Kalshi has clarified that its “legal in 50 states” claim pertains specifically to states and does not extend to tribal lands. The Ho-Chunk Nation agrees that tribes are not states but highlights that federally recognized tribes are situated within approximately 35 states. Consequently, the tribe asserts that Kalshi’s marketing should not imply that Indian lands fall outside state jurisdiction.

Context: Regulatory Efforts in Wisconsin

Separately, Wisconsin has sought to regulate prediction markets, but these efforts have encountered firm opposition from the CFTC, which governs these markets at the federal level.
