Two layers of rules

Federal authority, state friction.

01
Federal oversight
Some event contracts trade on exchanges overseen by the Commodity Futures Trading Commission. A federal appeals posture has generally favored federal authority over these designated markets.
02
State challenges
Several states have challenged operators, especially over sports-event contracts, through cease and desist letters and litigation. This is where most of the live friction sits.
03
Onchain and offshore
Crypto-native and offshore venues operate outside the US framework. Their standing for US persons is unsettled, and we do not treat reachability as legality.

FAQ

Colorado, and who decides, in short.

Are prediction markets legal in Colorado?

As of April 2026 the position is contested but Colorado has not taken enforcement action. Federally registered prediction market operators have served Colorado users, while the state has joined other states in urging the Commodity Futures Trading Commission to limit federal oversight of sports event contracts. The Colorado Division of Gaming has said it is monitoring the court cases. Sports contracts are the most disputed part. This is general information, not legal advice.

Has Colorado banned Kalshi or other prediction markets?

No public cease and desist or ban specific to Colorado was in place as of April 2026. Reporting describes prediction markets operating in Colorado outside the state regulated sports betting system, and the state pursuing a policy and federal rulemaking route rather than enforcement. Confirm the current position before relying on it.

What is Colorado position on sports event contracts?

Colorado Attorney General Phil Weiser joined a large group of state attorneys general urging the Commodity Futures Trading Commission to clarify that it does not have jurisdiction over sports related event contracts, arguing such platforms operate like unregulated sportsbooks. Sports contracts are therefore the most contested category. As of April 2026.

Can I use a prediction market in Colorado right now?

Federally overseen platforms have been accessible to Colorado users, but the legal debate is unresolved and could change. Confirm your own eligibility and the platform current status before acting, and treat sports contracts as the most contested. This is general information, not legal advice, current as of April 2026.

Who regulates these markets, the state or the federal government?

That is the core dispute. Federally registered event contracts are overseen by the Commodity Futures Trading Commission, while states including Colorado assert their own gambling and sports wagering authority and have asked the regulator to leave sports betting to the states. The question is unresolved as of April 2026.
