Ho-Chunk Nation Amends Kalshi Complaint as Tribal Gaming Row Escalates

The Ho-Chunk Nation has filed an amended complaint against prediction markets operator Kalshi, doubling down on its argument that the company’s marketing misrepresents the legal status of its products on tribal lands. A federal judge had already rejected the tribe’s initial claims under trademark and racketeering law, but allowed the case to proceed on other grounds. Now they’re back with a refocused strategy.

The Core Dispute

At its heart, this is a sovereignty question. The Ho-Chunk Nation argues that Kalshi’s claim to be “50 States Legal” is deliberately misleading because it glosses over tribal gaming law. Granted, Kalshi operates as a CFTC-regulated prediction markets platform rather than a traditional sportsbook, but the tribe contends that this distinction shouldn’t exempt the company from tribal gaming restrictions.

The Indian Gaming Regulatory Act gives federally recognized tribes the power to control what gaming activities occur on their lands. That’s not a minor technicality. It’s foundational to how tribal nations maintain economic and regulatory autonomy.

The Legal Mechanics

Here’s where it gets interesting. Kalshi’s products are event contracts regulated by the Commodity Futures Trading Commission, not the Gaming Commission. This regulatory classification lets Kalshi argue its offerings aren’t betting at all. But the Ho-Chunk Nation sees it differently: regulatory arbitrage, pure and simple. A way for Kalshi to sidestep tribal gaming rules by rebranding what many see as prediction gambling.

In May, US District Judge William M. Conley ruled that the tribe’s Lanham Act and RICO claims lacked precedent. That was a setback. It didn’t kill the case, though. The tribe has now refocused its amended complaint on IGRA provisions directly, arguing that tribes have explicit statutory authority to prohibit what they consider gaming activities.

The Marketing Question

The amended complaint also tackles a technical point Kalshi raised. The company said its “50 States Legal” claim applies to states as jurisdictions, not to Indian lands within those states. The Ho-Chunk Nation’s lawyers pushed back: roughly 35 federally recognized tribes operate within state boundaries, making Kalshi’s blanket claim either misleading or meaningless depending on how you read it.

That argument could really resonate with a judge reviewing whether marketing statements are deceptive. If Kalshi’s legality claims don’t clearly exclude tribal territories, and if tribes have the right to restrict gaming, then claiming across-the-board legality starts to look like a genuine problem.

What’s at Stake

This case matters beyond tribal politics. Should the Ho-Chunk Nation prevail, it could establish that CFTC regulation doesn’t exempt prediction markets from tribal gaming sovereignty. That would reshape how Kalshi and similar platforms operate nationwide on tribal lands. For tribes with gaming operations, it’s about protecting their regulatory space. For Kalshi, it’s about operational freedom.

Wisconsin’s own failed attempt to regulate prediction markets separately shows how fragmented this landscape remains. The CFTC pushed back hard on state-level restrictions. Tribal law, though? That sits in a different legal universe entirely.
