Missouri Prediction Markets: Best Sites & Legal Apps in 2026

Best prediction market apps in Missouri

This guide will explain how Missourians can buy and sell positions, highlight the top prediction markets in Missouri, and provide information about how MO prediction markets work. Here are our picks for the best Missouri prediction markets.

Are prediction markets legal in Missouri?

Yes, US prediction markets are legal in Missouri if the exchange is registered with the United States Commodity Futures Trading Commission (CFTC). This federal regulation makes such activity legal throughout Missouri as long as traders meet age and other eligibility requirements.

Unlike those in other states like neighboring Illinois, Missouri officials have so far not initiated any lawsuits, passed any laws, or taken any enforcement actions against prediction market exchange operators. Ongoing litigation could affect the status of exchanges in Missouri, however, especially cases before the US Eighth Circuit Court of Appeals or the US Supreme Court.

Minnesota, which is within the Eighth Circuit’s jurisdiction, is the target of a CFTC lawsuit that is in its early stage. Additionally, New Jersey officials have appealed a disfavorable decision for them in a dispute over prediction markets to the US Supreme Court.

Either of these cases or future appeals could have ramifications that would be relevant in MO. Missourians should watch for updates regarding this litigation.

How to trade prediction markets in Missouri

MO residents and visitors exploring their options for trading on the open US House seat representing the state’s sixth Congressional district will find that getting started with prediction market trading is simple. The process has six primary steps.

1. Pick your exchange: Look to make sure the exchange is registered with the CFTC and offers the kind of contracts in Missouri that you want to trade. It’s also wise to compare fees and see if the exchange has reliably significant market volume in the categories you’re interested in.
2. Fill in your account details: Exchange operators must collect contact and identity information from each trader to comply with CFTC regulations. Users can usually satisfy these requirements by providing government-issued documents.
3. Take advantage of welcome bonuses: Each exchange has unique offers and policies, such as whether the new user offer requires the use of a promo code. This is another good point of comparison for Missourians.
4. Add funds: The fun can’t begin without funds, so you need to deposit money into your account. The exchanges on our list accept ACH payments, debit cards, and even some forms of cryptocurrency, with policies independent for each operator.
5. Search the markets: As soon as the exchange confirms your deposit and registration, you can start browsing for a market that fits your interest and knowledge. Novice traders should stick to events that they are familiar with and look for markets with deep volume.
6. Claim your earnings: If you’re right about your prediction, you can withdraw your earnings as real money using the app’s or website’s cashier function. As with deposits, the payment sources you can withdraw to and how quickly the withdrawals process varies from exchange to exchange.

Example: trading Kansas City Royals futures

At the time of this writing, Kalshi had a live market on which Major League Baseball franchise will finish with the worst record at the end of the 2026 regular season. All 30 MLB teams are listed with “yes” and “no” options carrying individual prices based on trader sentiment.

At the moment, the Kansas City Royals were trading at $0.09 for the “yes” side and $0.93 for the “no” side. If you believe the Royals would finish with the league’s worst record, you would buy into the “yes” side at that price, while if you are convinced that another team will earn that unwanted distinction, you would buy into the “no” side.

A third option would be to wait to see if either side of the market moves to a price that you are more comfortable with. Many factors including managerial moves, on-field performance, and player injuries can affect perception of the team and therefore demand for these contracts.

For the sake of example, suppose you bought into the “yes” side at the current $0.09 price and shortstop Bobby Witt Jr. suffered a season-ending injury quickly thereafter. That might cause people who bought into this market backing other teams to sell their positions and want to buy into the Royals, which would make the price rise on the contracts you’re holding.

If the price rose to $0.29, you could sell, and realize a profit of $0.20 per contract. Whether that would make sense to do would hinge upon your reading of the situation and therein lies the risk of prediction market trading.

If you sold at that point, you would be giving up $0.71 of potential profit, as your potential profit upon settlement if the Royals ended up with the worst record would be $0.91 per contract (settlement on winning contracts is $1, so $1.00-$0.09=$0.91). However, if you don’t sell, you might miss your chance to realize any profit at all because you’ll get paid $0 per contract if another team finishes with a worse record than Kansas City.

How fees work

MO prediction markets make their money through fees, or what they charge traders for facilitating contracts. By and large, these fees follow two formats: per-transaction and upon-settlement.

Which of these formats the platform utilizes and the rates vary from exchange to exchange. The rates can also change based on the market type and transaction type.

DraftKings has a per-transaction fee of $0.01, which means that you will pay that amount on every transaction, including closing and opening positions. Polymarket, on the other hand, has an upon-settlement fee of 10%, which means that Polymarket keeps a tenth of your payout if your contracts settle as a win.

In either format, fees can represent a bigger chunk of your earnings the more profitable your position could be. To demonstrate that, consider Polymarket’s market on the number of regular-season wins for the Missouri Tigers football team in the 2026-27 season.

That market has yes/no contracts for options between 4+ and 12+ wins. If you bought into the “no” side of the 4+ wins option, each contract would cost you $0.10. Suppose then, that your total spend on those contracts was $10 and Mizzou only won three games during the season.

In that case, Polymarket’s 10% cut of your earnings would be $9.99. However, suppose that you instead bought into the “yes” side of 7+ wins with the same $10 at a per-contract price of $0.60.

If the Tigers won at least seven games, Polymarket would take $1.66 of your earnings, because the percentage remains the same but your profit was significantly lower. You can explore the impact of these fees more using DeFiRate’s fee calculator.

Upcoming sports events to trade on in Missouri

Sports event contracts are a strong example of how the pricing model in prediction markets rewards informed traders who execute decisions quickly. Consider the markets for the Kansas City Current’s chances to win the 2026 NWSL Championship.

At the time of this writing, Kansas City is on a three-match point streak, which has caused the price on the “yes” side of the market to increase. If the Current can prolong that streak, the rise will continue, and traders who bought in when Kansas City had lost three of its first four matches could get a good return.

Missouri prediction apps vs. sports betting

Missouri is one of the more recent states to introduce legal sports wagering, but trading prediction markets in MO is a distinct and separate activity. There are six main points of differentiation that Missourians should keep in mind.

• Age: Missouri law requires people to be at least 21 years of age to gamble. CFTC rules permit event contract trading for people as young as 18.
• Cost: Sportsbooks make money from bettors losing wagers while prediction market exchanges get their revenue from fees.
• Flexibility: Some sportsbooks will give bettors limited early-cash out options on certain wagers but as a rule, people using prediction markets have greater leverage for their movements in and out of markets.
• Pricing: Sportsbook operators set the odds for the wagers they offer according to their interests. On prediction market exchanges, contract demand sets prices.
• Structure: With traditional sportsbooks, you’re betting against the house. Prediction market exchanges are peer-to-peer forums and the exchange has no interest in how your contract settles.
• Regulation: The Missouri Gaming Commission regulates sportsbooks in MO. The CFTC regulates MO prediction markets.

The single greatest difference between prediction market trading and sports wagering is the influence the market bears on event contracts versus sports bets. Sportsbooks mostly set the terms for wagering on their apps while the market wields tremendous control on exchanges.

What markets can you trade on in Missouri?

MO prediction markets offer contracts on a wide swath of events, accommodating an array of traders’ expertises and interests. These contracts may involve events with global, national, or local relevance for Missourians.

• Cryptocurrency: Examples in this category include whether Bitcoin will hit $50,000 before $100,000 and the Ethereum price at the end of 2026. The best platform in this category is OG Predictions.
• Culture: In this category you’ll find contracts like whether Willard, MO-native Chappell Roan will have a top-10 song in 2026 and if Kansas City-native Don Cheadle will appear in the Avengers: Doomsday film. The best exchange for these markets is DKeX. 
• Economics: The choices within this genre incorporate price targets for specific stocks such as Missouri-based Emerson Electrics and O’Reilly Auto Parts and quarterly US government job reports. The top pick for these contracts is FanDuel Predict.
• Politics: Whether MO will redraw its Congressional district map before the November 2026 elections and whether the Republican Party will retain the governorship of Missouri are examples of markets that fit this label. The best choice for Missourians here is Polymarket.
• Sports: Futures and game markets covering the Blues, Cardinals, Chiefs, Current, Royals, and Tigers are all available in abundance, but MO prediction markets also dive deeper to include contracts like whether the St. Louis Billikens will qualify for the NCAA D1 men’s basketball national championship tournament. Our recommendation for Missourians in this regard is Kalshi. 
• Weather: Will it rain in Kansas City today or whether the high temperature in St. Louis will pass specified thresholds are two local examples for Missourians. Check out Polymarket for these contracts.

Missouri-specific rules for prediction markets

The CFTC regulates prediction market exchanges on a national basis and so far, MO officials have not attempted to enforce any state laws against exchange operators. Regardless, there are rules unique to prediction market trading that Missourians need to note.

The first of these rules pertains to age. CFTC rules state that traders must be at least 18 years of age, so that is the minimum on most exchanges.

Furthermore, Missourians are best-advised to consider any earnings they make from prediction market trading as taxable income. The best course of action is to keep detailed records of activity and consult a local tax professional to ensure accurate payment and reporting.

How Missouri works between products

Missouri regulates gambling but leaves the regulation of prediction market trading to the CFTC. CFTC regulations permit exchange operators a lot of room to make their own policies for how they will settle various contract types, what fees they charge, which markets they offer, and more.

MO residents and visitors should always read the settlement terms of every market they are considering. Additionally, people should verify the fees for each individual market.

Finally, not all platforms will provide access to the same types of markets or contain as extensive a selection in all the same categories. DraftKings and FanDuel Predictions not offering sports event contracts in MO is a great example of these differences.

As former Flutter CEO Peter Jackson explained, those companies don’t offer sports event contracts in MO because they operate their DraftKings- and FanDuel-branded sportsbooks in Missouri, and they want to protect those licenses. That’s a concern that Kalshi, OG, and Polymarket don’t share, so they do offer sports event contracts in MO. 

Prediction markets continue to evolve

So far, Missouri officials haven’t yet involved themselves in the ongoing litigation over prediction market trading that involves many other US states. Lawmakers in MO also haven’t approached the subject of crafting new statutes for the activity to date.

Regardless, multiple examples of this litigation could impact the availability and structure of prediction markets in Missouri. The two clearest current examples of this are the CFTC’s lawsuit against Minnesota officials and Kalshi’s lawsuit against New Jersey officials.

The CFTC sued Minnesota officials in May after the state enacted a new law that bans almost all types of prediction market trading in the state. The CFTC secured a preliminary injunction that temporarily blocks Minnesota officials from enforcing the law, but the case has yet to go to trial and Minnesota could appeal the ruling on the injunction to the US Eighth Circuit Court of Appeals.

Missouri is within the jurisdiction of the 8th Circuit, so any rulings on prediction market legality from that court could affect how prediction markets operate in MO. The highest court in the land is the venue of the other case worth watching.

Kalshi sued New Jersey officials after gambling regulators in that state sent a cease-and-desist letter demanding that Kalshi stop offering sports event contracts there. Kalshi secured a preliminary injunction against that action, and the Third Circuit Court of Appeals affirmed that injunction.

The defendants in that case plan to file a petition for the US Supreme Court to review the Third Circuit’s affirmation. Because it’s the highest court in the US, any decision from the Supreme Court would have ramifications for prediction markets in MO.
