Are prediction markets gambling?
Short answer: regulated prediction markets are treated as financial markets, not gambling. The leading US venues operate under the Commodity Futures Trading Commission (CFTC), the federal regulator for futures and derivatives, rather than under state gambling law. Here is what actually separates an event contract from a wager.
- Regulated prediction markets are overseen by the CFTC as financial markets, not by state gambling regulators.
- Kalshi is a CFTC-regulated DCM; Polymarket operates as a CFTC-regulated market via QCEX designation (Dec 2025).
- An event contract has a transparent price equal to implied probability, two-sided liquidity, and the option to exit before resolution.
- Trading still carries real financial risk: regulation governs market integrity, not your profit or loss.
- This page is informational, not legal advice; availability and rules vary by state.
How the legal framing works
In the United States, an event contract that resolves to $1 or $0 based on a real-world outcome is a derivative. Derivatives are regulated federally by the CFTC under the Commodity Exchange Act. That is a different legal track from a sportsbook wager, which is licensed and taxed state by state under gambling law.
This is not a marketing distinction. It determines which agency supervises the platform, what market-integrity and custody rules apply, and where the product can legally be offered.
Event contract vs gambling: the practical differences
- Price discovery: a prediction market price is set by traders and equals the implied probability of the outcome. A sportsbook posts fixed odds with a built-in margin.
- Two-sided market: you can buy YES or NO, effectively taking either side, and others can trade against you. A wager is a one-way ticket against the house.
- Exit before resolution: contracts trade continuously, so you can usually sell at the current price before the event finishes. A settled bet cannot be sold.
- Oversight: CFTC-regulated venues face federal rules on reporting, market manipulation and fund custody.
What regulation does and does not do
Regulation is about how the market operates, not about removing risk. You can still lose what you put into a contract if the outcome does not happen. The point is that a regulated exchange is supervised, its prices are transparent, and there are federal rules behind it.

Frequently asked questions
Are prediction markets gambling?
Legally, regulated prediction markets are treated as financial markets, not gambling. Platforms like Kalshi and Polymarket operate under the Commodity Futures Trading Commission (CFTC), the same federal regulator that oversees futures and derivatives, rather than under state gambling law.
What is the difference between an event contract and a bet?
An event contract is a tradable instrument with a transparent price that equals implied probability, two-sided liquidity, and the ability to exit before resolution. A sportsbook bet is a fixed-odds wager against the house with a built-in margin and no secondary market. The mechanics, oversight and price discovery differ.
Who regulates prediction markets in the US?
The CFTC. Kalshi is a CFTC-regulated designated contract market (DCM). Polymarket operates as a CFTC-regulated market via its QCEX designation as of December 2025. ProphetX is a licensed peer-to-peer sports exchange.
Does that mean prediction markets are risk-free?
No. You can lose the money you put into a contract if the outcome does not happen. Regulation governs how the market operates and how it is overseen; it does not remove the financial risk of trading.
Why does the distinction matter?
It affects who can offer the product, in which states, and under what consumer protections. CFTC oversight brings federal rules on market integrity, custody and reporting that state-licensed sportsbooks are not subject to in the same way.
