Best prediction market apps in Wisconsin

These platforms allow people in WI a chance to make predictions about these events with tremendous flexibility for moving in and out of positions, plus pricing based on demand for markets instead of a bookmaker’s line. This guide compares the best prediction markets in Wisconsin and covers what you can trade, current promos, and the regulatory landscape.

Are prediction markets legal in Wisconsin?

Yes, exchanges like Kalshi and Polymarket are registered with the United States Commodity Futures Trading Commission (CFTC), meaning that it is legal for people in WI to trade on them. However, state officials in Wisconsin are challenging the legality of sports event contracts on many platforms in court.

In March 2026, Wisconsin Elections Commission Chair Ann Jacobs shared social media posts reminding voters in the state that WI law bans wagering on elections. Because state law lets anyone challenge a ballot cast by someone who bet on their own race, a voter who does so risks having that ballot challenged and voided through the state’s existing process, independent of any separate criminal case.

Wisconsin Attorney General Josh Kaul sued multiple exchange operators in April 2026 in state court, arguing that the sports event contracts on the platforms violate the state’s gambling laws. The CFTC responded by suing Kaul and other Wisconsin officials in federal court that same month, seeking to block the state from enforcing its gambling laws against the exchanges. A federal judge denied that request in July 2026.

At the time of this writing, a trial is pending in state court and the CFTC is weighing its appeal options in federal court. There is also a potential appeal from New Jersey officials to the US Supreme Court that could affect prediction market access in Wisconsin, but those authorities have yet to actually file their petition.

WI prediction market apps reviewed

Our picks for the top prediction markets in Wisconsin center on five exchanges that are all registered with the CFTC but offer distinct experiences for Wisconsinites due to varying strengths.

• Polymarket: Best for “purple state” political experts with their eyes on the headlines
• Kalshi: Best for Brewers and Packers fans interested in trading sports
• FanDuel Predicts: Best for inexperienced traders who want a user-friendly interface
• OG Predictions: Best for people in WI who value a social experience online 
• DKeX: Best for Wisconsinites seeking responsible trading interventions

Polymarket US

Best for “purple state” political experts with their eyes on the headlines

Polymarket gets top billing in WI for how it builds on its already robust offerings for event contracts based on political developments. Kalshi may boast deeper volume and greater variety in other categories, but Wisconsinites will lack for nothing searching through the options on Polymarket in the political context.

Available markets at Polymarket right now include whether the Democratic Party will retain the governorship of WI in November 2026’s election and which party will win all eight of the US House seats representing the state. There are even contracts related to the competitive race for Wisconsin’s third congressional district.

Kalshi

Best for Brewers and Packers fans interested in trading on sports

Kalshi gets our pick for the best prediction market exchange in WI because of its easy-to-use platform but for many in Wisconsin, the real difference maker is Kalshi’s consistent market variety and volume for sports event contracts. With that being said, Polymarket often bests Kalshi in regard to offering lower fees.

If you’re interested in trading on Green Bay Packers or Milwaukee Brewers futures and games, Kalshi has those in abundance. At the time of this writing, those options included markets on whether the Brewers would win the National League Central division and how many preseason games Packers quarterback Jordan Love would play in for 2026.

Gemini Predictions

Regulated on the REGULATED · live in 42 states

Gemini Predictions runs inside the Gemini crypto exchange itself, letting traders move from crypto holdings straight into event contracts on the same account. Its built-in “Command Center” adds AI-powered market summaries and personalized signals, a feature none of the other exchanges here currently match.

Wisconsinites already trading Bitcoin or Ethereum on Gemini may find this the most convenient entry point into prediction markets, since it skips the step of funding a separate account elsewhere.

FanDuel

Best for inexperienced traders who want a user-friendly interface

People in WI who have experience with FanDuel’s daily fantasy sports platform will find making the transition to FanDuel Predicts quite simple, as the FanDuel Predicts app and website deploy a nearly identical interface. At the same time, some Wisconsinites may encounter some disappointment in regard to market variety on FanDuel Predicts, especially in the context of sports event contracts.

The culture markets at FanDuel Predicts are full of opportunities close to home in WI. An example is whether Kenosha native Mark Ruffalo will win the Emmy for Outstanding Lead Actor in a Drama Series.

OG Predictions

Best for people in WI who value a social experience online

OG Predictions stands out among WI prediction markets for its integration of user forums and a rewards program for traders. None of the other exchanges on this list offer those amenities, but OG Predictions can also lag behind when it comes to higher fees and lower market volume in comparison to Kalshi and Polymarket.

OG Predictions offers sports event contracts just as Kalshi and Polymarket do, which is great news for Badgers fans in Wisconsin. An example of a relevant market on OG Predictions is how many Big Ten conference games the Badgers will win during the 2026-27 college football season.

How to trade prediction markets in Wisconsin

Wisconsin residents and visitors can start buying and selling prediction markets online related to their interests in Marquette University Golden Eagles basketball and the US House race in Wisconsin’s competitive third district in just six steps.

1. Pick an exchange: Before you go any further, make sure the platform you’re considering is registered with the CFTC and operates in Wisconsin, then check to see if the exchange offers the types of contracts that you want to trade and verify the fees.
2. Confirm your identity: CFTC regulations require you to share contact and identification information with the exchange using government-issued documents.
3. Look for a welcome bonus: Many of the platforms on our list automatically grant new user bonuses if they offer such deals but it’s wise to make sure that you don’t need a promo code to take advantage of the offer.
4. Put funds in your account: The exact payment methods accepted will vary especially in regard to cryptocurrency but all of the exchanges usually accept ACH payments and debit cards.
5. Search for a contract you’re interested in: Markets are priced from $0.01 to $1 and tied to simple yes or no outcomes. It’s best to start with something that you’re familiar with.
6. Withdraw any earnings: If your prediction proves accurate, you’ll get a positive settlement. You can then withdraw those earnings as real money but pay attention to withdrawal policies because the time frames can deviate significantly based on the payment source you elect.

Example: Trading Milwaukee Bucks futures

At this time, Kalshi is offering a market on the number of regular-season wins that the Milwaukee Bucks will record during the 2026-27 season. There are 22 individual contracts in that market, one for the “yes” side and one for the “no” side of 11 different win totals ranging from 15+ to 65+.

For the sake of this example, suppose you bought into the “yes” side of 30+ wins at the current price of $0.40. If the Bucks won 29 or fewer games, your contract would settle at $0.

If the Bucks won at least 30 games, though, your contract would settle at $1. That would mean that you would get $0.60 in profit for each position you bought if you waited until the contract settled.

However, people in WI don’t have to wait until their contracts settle to potentially enjoy a profit. Suppose the Bucks got off to a hot start, and demand for your contract soared on Kalshi.

As a result, the price for the contracts you’re holding might rise to $0.65. You could sell at that point and get a profit of $0.25 per position.

In that instance, you would sacrifice $0.35 of potential profit but you would avoid the risk that comes with a long 82-game regular season schedule in the NBA, too. Making the best out of your positions is a matter of timing your moves and weighing reward vs. risk.

How fees work

Wisconsinites interested in Brewers or Bucks futures will find plenty of markets on WI prediction markets, but exchanges also charge fees that vary by platform and by contract price. Check each platform’s fee schedule before you trade, since the rules aren’t the same everywhere.

Fees are typically highest on contracts trading near the middle of the price range and taper off toward the extremes. A contract priced near $0.50 reflects the most uncertainty, so exchanges charge more to facilitate that trade; a contract priced near $0.10 or $0.90 reflects a market that has largely made up its mind, so the fee is smaller.

That structure matters more than it looks. Fees are typically assessed as a small percentage of the contract’s price rather than a flat percentage of your total spend, so the profit margin they eat into shifts depending on where you’re trading. A contract at $0.10 has far more room to run if you’re right — a $0.90 payout on a winning $0.10 contract — but a small fee still claims a larger share of that bigger potential profit than the same fee would on a $0.60 contract with less room to climb.

Run your own numbers with DeFi Rate’s fee calculator before you trade, especially on lower-priced, longer-odds contracts where fees have the most room to cut into your upside.

Upcoming sports events to trade on in Wisconsin

Sports event contracts in WI are some of the most popular prediction markets because of the vast interest and abundantly available reporting on developments in the arena. Going back to the Bucks regular-season win total example allows for a demonstration of how dynamic and sensitive the pricing of these markets can be.

Imagine that Kevin Porter Jr. suffered a significant injury midway through the upcoming season. The public would react immediately to this news, and that change in sentiment about the Bucks could make the price for contracts on the Bucks win total change on both sides of all the options in the market.

That is a representation of the risk that prediction market traders take. Events are unpredictable and your position can go from enviable to regretful very quickly.

WI prediction markets vs. sports betting

Wisconsinites currently only have access to legal sports wagering at tribal casinos, but regulated online sports wagering is coming to the state. Until then and from that time, prediction market trading will be available as a distinct, separate experience on five main points.

• Cost: Sportsbooks make money through bettors’ losses while prediction markets make money through user fees.
• Flexibility: Prediction markets tend to provide greater flexibility to enter and exit contract positions in comparison to sportsbooks.
• Pricing: Traders set prices for contracts through their demand for markets while sportsbooks set their lines according to their interests.
• Regulation: Online sportsbooks in WI will be regulated by tribal governments and the Wisconsin Division of Gaming. The US CFTC regulates WI prediction markets.
• Structure: Sports bets are against the house but prediction markets are peer-to-peer transactions against other users.

The biggest difference between event contract trading and traditional sports wagering in WI is the influence that the market has on contracts, controlling pricing and impacting whether exchanges offer markets.

What markets can you trade on in Wisconsin?

WI prediction markets offer contracts on more events than many people in the state might think, and they do it all in a regulated and transparent environment.

• Cryptocurrency: You’ll find contracts like the price of Bitcoin at the end of 2026 and daily markets for the price of Ethereum. The best platform for this category is OG Predictions.
• Culture: Contracts of interest in this category include whether Mark Ruffalo will appear in the Avengers: Doomsday film and mention markets for Wisconsin celebrities. The top choice in this category is FanDuel Predicts.
• Economics: Popular markets here involve Federal Reserve interest rate decisions and Dow Jones Industrial Averages. DKeX is the best choice in this genre.
• Politics: Wisconsinites can trade on outcomes in the state’s US House races and mention markets for WI political figures. Our recommendation for these contracts is Polymarket.
• Sports: Whether you’re looking for contracts related to the Badgers, Brewers, Bucks, Golden Eagles, or Packers, there are myriad markets for awards, futures, and games. The best platform in this regard is Kalshi. 
• Weather: You can trade on whether it will rain in Milwaukee and national weather events as well. Look for these contracts at Kalshi, too.

Wisconsin-specific rules for prediction markets

The CFTC regulates prediction markets on a national scale, including activity on the platforms in WI. Regardless, those rules leave a lot of room for exchange operators to customize their offerings and policies for specific populations like Wisconsin residents.

One example of national congruence is the age requirement for prediction market trading. CFTC regulations establish a minimum age of 18 for this activity, so that’s the standard for all the CFTC-registered exchanges in Wisconsin and across the country.

The IRS and the Wisconsin Dept. of Revenue have not yet issued any specific guidance on earnings from prediction market trading, so it’s wise for Wisconsin residents to keep detailed records of their activity and consult a tax professional in the state. One potentially unique component of WI prediction market trading that could become more prominent is political markets.

Because of Jacobs’ statement on WI election law, exchange operators may be particularly on-guard for any enforcement activity that Wisconsin officials undertake. At the time of this writing, though, there have been no actual enforcement attempts in this context and CFTC-registered exchanges continue to offer political markets.

How Wisconsin works between products

Other ways that CFTC-regulated exchanges enjoy flexibility are making their own decisions about which contracts to offer and setting policies for how they will settle those contracts. For that reason, market availability and settlement rules can vary not just from one WI prediction market to another but depending on the contract type on the same exchange.

The best example of this diversity is sports event contracts in WI. DKeX and FanDuel Predicts do not offer these contracts. Flutter CEO Peter Jackson explained the reasoning behind FanDuel Predicts’ policy on an earnings call: “We always said we wouldn’t do anything to damage our existing business.” DraftKings has taken the same approach with DKeX, since both companies operate in the gambling industry and may seek Wisconsin sports betting licenses in the future.

On the other hand, Kalshi, OG Predictions, and Polymarket are not involved in the gambling industry. This is why they choose to offer sports event contracts while DKeX and FanDuel Predicts have foregone that option.

Prediction markets continue to evolve

The CFTC has been active in insisting that it is the sole regulatory body of prediction market trading in the US, including in Wisconsin. Wisconsin authorities have insisted that sports event contracts violate the state’s gambling laws.

Both sides of the debate have been vociferous enough about their positions to spend resources on litigation. At this time, the CFTC is considering appeal options from a defeat in federal court and Wisconsin authorities are moving forward with their civil lawsuits against multiple prediction market exchange operators in state court.

Decisions in these cases could quickly change the status of WI prediction markets, as could a potential appeal to the US Supreme Court on similar grounds out of New Jersey. It’s worth noting, though, that WI officials are only challenging the legality of sports event contracts, and have not done the same regarding other types of markets available on exchanges.

Things to know before you trade in Wisconsin

WI residents and visitors should always ensure that the exchange they trade on is registered with the CFTC. There are a few more considerations beyond that concern, though.

• Exchanges set their own rules in many aspects of the user experience: Traders need to verify fees and settlement rules for specific contracts and remember that the availability of desired markets changes from one platform to the next.
• Prediction markets are different from gambling platforms: Exchanges offer a peer-to-peer trading format in which market prices swing on user beliefs about events.
• Wisconsin is in court over sports contracts and election-contract voting rules: Pending sports-contract cases could change available markets. In a separate voter challenge, Judge Byron B. Conway denied Joseph Giganti, Sr.’s preliminary-injunction motion on November 2, 2026. The inspected order excerpt establishes that denial, not a dismissal or final merits judgment.
