Wisconsin’s Ho-Chunk Nation filed a court brief Friday seeking to amend its complaint against Kalshi with regard to how it characterized the prediction market’s advertising. The brief is in response to a May ruling by a federal judge that the tribe could continue with part of its complaint under the Indian Gaming Regulatory Act (IGRA), but that its Lanham Act and Racketeer Influenced and Corrupt Organizations Act claims are invalid.
The Ho-Chunks are suing Kalshi to try to keep the prediction market from offering sports event contracts on the tribe’s land. The tribe compacted to offer legal gaming on its reservation in 2024, but it has not yet compacted to add online sports betting.
