Offering a unique way to interact with sports, politics and more, prediction markets are becoming increasingly popular. But how do prediction market regulations work? Are these sites available across the US and are members safe?
Prediction markets allow members to buy ‘Yes’ or ‘No’ contracts on topics like ‘Will the next President be a Democrat?’ This system means that they come under the remit of the Commodity Futures Trading Commission (CFTC) and are legal at federal level across all states. This has been challenged in some areas, but new guidance looks set to confirm and expand the industry.
To understand how prediction markets are able to provide their services to users, it’s necessary to briefly outline how they work. Prediction markets allow users to buy and sell Yes/No contracts on real life events. Each contract has a price between $0.01 and $0.99 based on how likely it is to occur. In the table below, we’ve outlined an example of how this would work:
| Trade | Implied probability | Yes price | No price |
| Will the Buffalo Bills win the Super Bowl in 2027? | 65% | $0.65 | $0.34 |
If the Bills go on to win, each ‘Yes’ share would settle at $1 each. This would give you a profit of $1-$0.65=$0.35 on each share. If the Bills did not win, each contract would be worth $0, meaning you lose your money.
Prediction exchanges don’t set their own prices for trades. Instead, these are 100% driven by the market, influenced by other traders and external events. Sites such as Kalshi charge users a small fee to facilitate a trade but have no stake in the outcome. This model puts prediction sites into the category of financial exchanges, overseen by the CFTC (Commodity Futures Trading Commission) - the government body which has regulated this sector since 1974 and ultimately reports to Congress.
One of the best bits about prediction markets is the massive choice of event contracts, but there are several other pros you should consider:
As CFTC regulated sites, the brands we recommend are required to meet strict criteria to protect members. This includes:
Prediction markets publish information on each trade including its current value and the method of resolution. For example, a news outlet could detail the final score of a sports event. Knowing this information before making a trade helps members to judge how changes in the market could impact prices.
Regulated prediction markets are subject to the Bank Secrecy Act and other legislation, which means they must follow strict anti-money laundering requirements. These are usually set by the individual prediction market as part of the wider framework and include reporting any suspicious activity or transactions.
Accessing prediction markets is strictly an adult activity so any prospective users are required to complete KYC (Know Your Customer_ verification. To meet these conditions, members must provide certain pieces of information and evidence. This could include a copy of an ID document, such as a passport, as well as your Social Security Number and a selfie. This requirement ensures that only adults are able to register and make trades.
Any members with inside information on event contracts are forbidden from trading. That includes athletes or people associated with a particular sporting event, employees at companies being traded or anyone involved with political event outcomes. Doing so would mean that you are removed from the prediction market.

Prediction market regulations can be complex depending. They’re also subject to changes as the legal landscape alters. There have been several challenges issued against prediction markets in some states; however, a very recent series of legal actions by the CFTC has resulted in a formal document of proposed rules regarding prediction markets. These proposed rules would clearly outline which markets are and aren’t available for trades and will allow all eligible members to sign up and trade at the top prediction market sites.

Prediction markets involve financial risk, and outcomes are never guaranteed. In light of this, trading should always be controlled and enjoyable. Keep your activity in check by following responsible trading practices such as:
Only trade money you can afford to lose and stop when your budget is reached.
Avoid increasing trade size or frequency to recover losses.
Don't trade when stressed, tired, emotional, or under the influence.
Take breaks and avoid letting trading interfere with daily life.
Learn how contracts, pricing, fees, and settlement work before trading.
Use spending limits, account history, or self-exclusion tools where available.
