Clarity Act clears Senate panel as tribes warn of sovereignty loss

A Senate committee voted to advance the Clarity Act last month, and the political geography of that vote matters more than the margin. The bill would establish federal jurisdiction over prediction market event contracts, explicitly preempting state gambling laws. For Kalshi, that is the legislative solution to every courtroom it has lost. For the five federally recognized tribes that sent testimony to the committee, it is something closer to an existential threat.

The tribes' argument is not sentimental. It runs through the Indian Gaming Regulatory Act, which grants tribes the authority to operate gaming on tribal lands as a matter of sovereignty, and through decades of compact negotiations with state governments that produced the revenue streams funding schools, health clinics, and infrastructure that federal appropriations never covered. The Clarity Act, in their reading, would allow a CFTC-registered exchange to offer sports outcome contracts to anyone in the country with a brokerage account, without touching a state compact or a tribal revenue agreement. That is not deregulation. That is a structural reallocation of who captures the money.

The preemption argument the tribes are making is technically sophisticated. Federal law preempts state law under the Supremacy Clause, but it does not automatically preempt tribal law in the same way, and IGRA creates a statutory framework with its own internal logic. Whether the Clarity Act, as drafted, would override tribal gaming compacts or simply sit beside them is a question the bill's text does not cleanly answer. I have read enough preemption disputes to know that ambiguity at the drafting stage becomes litigation at the enforcement stage. The tribes know this too, which is why their ask is not to kill the bill but to amend it with an explicit carve-out preserving compact authority.

Congress has given those carve-outs before. PASPA, before the Supreme Court struck it down in 2018, included tribal protections. The Wire Act's application to tribal operations has been negotiated through guidance and carve-out language for decades. The pattern is established. Whether the Clarity Act's sponsors move to include it is a different kind of question — one about political will and whose coalition matters more to the bill's floor prospects.

The prediction market Polymarket has an active contract on Clarity Act passage. My view is that it is pricing the legislative path without adequately weighting the tribal opposition's structural leverage. Tribes have lobbying infrastructure, established congressional relationships, and a legal argument that does not depend on the outcome of Kalshi v. New Jersey or any other pending case. Their objection survives every federal court ruling. That makes them a different kind of obstacle than a state attorney general — and a harder one to route around.

The relevant legal standard is whether the Clarity Act's preemption clause, as written, constitutes a clear and manifest congressional intent to supersede tribal compact authority under IGRA. Without that clarity, courts applying the canon of construction that ambiguous statutes are not read to abrogate tribal rights will find the carve-out by implication anyway.
