Just over a year ago, prediction markets like Kalshi and Polymarket were staring down a federal proposal that would have banned their most popular product category outright: sports and politics contracts. Now the CFTC's own chair is calling that approach a failure and asking staff to write clear rules instead — a genuine regulatory reversal playing out while more than a dozen states are still fighting these platforms in court.

What almost happened

The CFTC had a 2024 proposal on the table that would have prohibited sports- and politics-related event contracts on prediction market platforms — effectively banning the category of contract that made Kalshi and Polymarket household names during the last two election and football cycles. A related 2025 advisory separately discouraged platforms from offering sports contracts at all, citing unresolved legal concerns about how those contracts fit the agency's statutory mandate.

What actually happened instead

CFTC Chair Michael Selig reversed both, directing staff to withdraw the proposed ban and abandon the 2025 advisory. His stated reasoning was blunt: the existing framework had proven difficult to apply and had failed market participants, creating exactly the kind of regulatory uncertainty that discourages legitimate business rather than protecting anyone. In its place, Selig tasked the agency with drafting clear standards for event contracts — rules that define what's permitted rather than simply prohibiting an entire product category and hoping the definition problem sorts itself out later.

The states haven't gotten the same memo

Federal reversal or not, the legal fight over these platforms is far from settled. Nevada and Utah have blocked prediction-market operations outright, Michigan temporarily suspended Kalshi, and lawsuits or active enforcement actions are underway in Arizona, California, Connecticut, Illinois, Maryland, Massachusetts, Minnesota, New York, Ohio, Rhode Island, Tennessee, Texas, and Washington. The core dispute in every one of those states is the same: whether a sports-outcome contract is a federally regulated financial instrument (the CFTC's and the platforms' position) or an unlicensed sportsbook operating without a state gambling license (the states' position). The CFTC has countersued several states attempting to enforce their own rules against these platforms, arguing its federal jurisdiction as a designated-contract-market regulator preempts state gambling law entirely.

Why the reversal happened now

A ban-first approach makes political sense when a new product category looks unfamiliar and potentially risky; it makes a lot less sense once that category has grown large enough that an outright ban starts to look like picking a fight with a real industry rather than closing a loophole. Kalshi and Polymarket have both grown dramatically in trading volume and public profile over the past two years, and Selig's own language — a framework that "failed our market participants" — reads as an acknowledgment that the ban approach was reactive policy that hadn't kept pace with how large and mainstream these platforms had already become.

Why it matters

This is a case study in how fast crypto- and fintech-adjacent industries can flip a regulator's posture once they reach enough scale and political relevance — from "we might ban this" to "we need clear rules for this" in about a year. It doesn't resolve the harder fight, which is happening state by state and will likely need either a court ruling on federal preemption or new legislation to fully settle. But it does remove the most existential threat these platforms faced at the federal level, and it's a template other emerging crypto-adjacent product categories — DeFi-based derivatives chief among them — will be watching closely as a possible playbook for their own regulatory fights. It's also a useful case study in regulatory humility: an agency publicly admitting its own proposed framework failed the people it was meant to govern is a rarer and, in its own way, more consequential signal than the specific rule change itself. The state-level fights aren't going away regardless, and the eventual resolution there — whichever way it goes — will matter more to these platforms' long-term business than anything the CFTC does at the federal level alone.

Frequently asked

Are Kalshi and Polymarket legal in the U.S. right now?

Yes, at the federal level — both operate as CFTC-regulated exchanges (designated contract markets), which the CFTC treats as giving it exclusive federal jurisdiction over them. Legality at the state level is a separate and much messier picture, with active bans or lawsuits in more than a dozen states.

What was the rule that got dropped?

A 2024 CFTC proposal would have prohibited sports- and politics-related event contracts on prediction market platforms entirely. Chair Michael Selig directed staff to withdraw it, along with a related 2025 advisory that had discouraged platforms from offering sports contracts over legal concerns.

Why do some states say these platforms are illegal if the CFTC says they're fine?

States argue that sports-related prediction contracts are functionally identical to sports betting, which is state-regulated and requires state licensing — meaning platforms like Kalshi are operating as unlicensed sportsbooks in their view. The CFTC's position is that its federal jurisdiction over these products as financial exchange contracts preempts state gambling law entirely; that jurisdictional fight is still being litigated state by state.
