Frank AmmiranteMy recommendation

Kalshi is my favorite prediction market because it has the most trading volume. Higher volume typically means more buyers and sellers are active. This can lead to better liquidity and an easier time entering or exiting a position at a competitive price.

Aside from liquidity, Kalshi also boasts a wide selection of markets, including sports, politics, economics, and more.

1. Kalshi – best for market selection and liquidity

Frank AmmiranteMy expert take

Kalshi is my favorite prediction market because of its combination of trading volume and market variety. Kalshi generated approximately $37.7 billion in trading volume in July 2026, compared with $12.9 billion from Polymarket. Better liquidity makes it much easier to enter and exit positions at fair prices.

Whether you're new to prediction markets or are an experienced trader, Kalshi offers the most well-rounded experience in the industry.

Why we like it

  • ✓Industry-leading trading volume: Kalshi has the most volume among prediction markets. Greater liquidity is especially valuable on an exchange because you need other traders willing to buy or sell your contracts.
  • ✓Thousands of markets: You can trade sports alongside politics, finance, economics, crypto, weather, climate, culture, and other real-world events. The broad selection makes Kalshi useful beyond traditional sports prediction apps.
  • ✓Fast withdrawal options: Crypto withdrawals typically arrive within 30 minutes, while debit-card withdrawals generally reach your card within a few hours.

What we'd change

  • –Kalshi's trading fees vary with contract price and can differ for specific market categories. This makes costs less straightforward than platforms using a simple flat commission.

User feedback

Kalshi has strong ratings at the App Store, scoring 4.8/5 across 478K reviews. Users praised the user-friendly app design.

"No question about it being the best. There is something for everyone, and if you can learn a niche or you are good at researching or are just lucky, then this is for you."

2. Polymarket – best for politics and current events

Frank AmmiranteMy expert take

Polymarket is one of my top prediction market apps for trading politics and current events. The platform now offers markets covering elections, government policy, economics, sports, and other news outcomes, including extensive coverage of US 2026 midterms odds. Trading activity is also growing quickly, with Polymarket generating approximately $5 billion in trading volume in July 2026.

I especially like Polymarket for users who closely follow politics and breaking news because new markets can provide plenty of opportunities to trade on developing events.

Why we like it

  • ✓Strong political and current-event markets: Polymarket offers extensive coverage of elections, government policy, geopolitics, and economics, including markets on the 2026 midterms, 2028 US presidential election predictions, and Federal Reserve decisions.
  • ✓Growing trading activity: Polymarket generated approximately $5 billion in trading volume in July 2026. Higher activity can improve liquidity, making it easier to find buyers and sellers in popular markets.
  • ✓Rewards liquidity providers: Polymarket rewards makers who add liquidity to its order book, while takers pay a price-dependent trading fee.

What we'd change

  • –Polymarket uses a price-dependent taker fee rather than a simple flat commission. Fees are highest around 50-cent contracts and decrease as prices move closer to $0 or $1, which can make trading costs less intuitive for beginners.

User feedback

Polymarket has strong ratings, with 4.6/5 stars across 53K App Store reviews. Several users enjoyed how the app was easy to use.

"I have tried many crypto trading applications. Many are confusing and exhausting, but this app is simple. It offers statistics that are helpful for beginners."

3. Novig – best for competitive sports pricing

CodePRED

Frank AmmiranteMy expert take

Novig stands out for sports traders who care about pricing because all pregame straight trades on its app and website are currently without fees. Rather than accepting sportsbook odds, users can take an existing price or set their own price and wait for another trader to match it. With moneylines, spreads, totals, player props, futures, and live markets available, Novig is an appealing option for sports traders looking for competitive pricing.

Why we like it

  • ✓Fee-free pregame straight trades: Novig currently charges no maker or taker fees on pregame straight trades placed through its app. Live taker trades and parlays use separate fee structures.
  • ✓More control over pricing: You can accept an existing price or set your own price and wait for another trader to match it. Maker orders must use Novig's approved price increments, but this still gives users more control than simply accepting fixed sportsbook odds.
  • ✓Strong sports market selection: Novig covers NFL predictions, college football, MLB, NBA/WNBA, college basketball, NHL, golf, tennis, and MMA, with moneylines, spreads, totals, player props, futures, and live trading available depending on the sport.

What we'd change

  • –Novig remains focused on sports, so traders interested in politics, economics, crypto, weather and entertainment markets will find a broader event selection on platforms such as Kalshi and Polymarket.

User feedback

Novig has strong ratings at the App Store, sitting at 4.6/5 across 3.9K reviews. One user talked about how it features an intuitive experience.

"Novig presents an innovative and refreshing approach, standing out for its ease of use and intuitive design."

4. ProphetX – best for competitive sports pricing

Frank AmmiranteMy expert take

ProphetX is one of my favorite prediction market platforms for sports because traders have more control over pricing. Instead of simply accepting sportsbook odds, you can trade at the current market price or set your own price and wait for another participant to match it. Straight trades are also charged just 2% of net gains per market, making ProphetX an appealing option for price-conscious sports traders.

Why we like it

  • ✓More control over pricing: ProphetX lets you trade at the current market price or set your own price and wait for another participant to match it. This gives sports traders more control over the price they receive.
  • ✓Competitive trading fees: Straight trades are charged 2% of net gains per market, meaning the fee applies when your net gains in that market are positive. Parlays use a separate fee schedule.
  • ✓Built specifically for sports: ProphetX offers moneylines, spreads, totals, and player props across major sports, with positions that can be bought or sold before settlement.

What we'd change

  • –ProphetX is heavily focused on sports, so traders looking for politics, economics, crypto, weather and other non-sports prediction markets will find more variety on other platforms.

User feedback

ProphetX has excellent ratings at the App Store, scoring 4.8/5 across 3.2K reviews. One user highlighted the favorable pricing you can get at ProphetX.

"It's truly a game-changer. The biggest draw is getting the best prices available."

Frank AmmiranteMy expert take

Underdog is one of my top choices for sports fans because prediction markets are built directly into the same app as its established fantasy products. It supports pregame, in-game, and multi-event sports contracts. This focus on sports makes Underdog particularly appealing to users who primarily want to trade on games and other sports outcomes.

Why we like it

  • ✓Sports-first experience: Underdog offers Prediction Picks across major sports including the NFL, NBA, NHL, MLB, college football and basketball, soccer, WNBA, MMA, esports and tennis, although availability varies.
  • ✓Fantasy and predictions together: Prediction Picks live in the same app and account as Underdog's fantasy contests, so users can switch between the two without a separate signup.
  • ✓Flexible sports contracts: Users can trade outcomes such as game winners, spreads, and totals, with pregame, in-game, and multi-event contracts available.

What we'd change

  • –Standard Underdog Bonus Funds cannot be used directly on Prediction Picks, and availability varies by state.

User feedback

Underdog Predictions is integrated with its other offerings on the same app. It currently has a 4.8/5 rating across 316K reviews on the App Store.

"Love the quick payout action", with users noting smooth financial transactions.

6. FanDuel Predicts – best for a user-friendly interface

Frank AmmiranteMy expert take

FanDuel Predicts is one of my top choices for beginners because it has a user-friendly interface that most are familiar with, since FanDuel has been an industry leader for a number of years. The platform covers sports, culture, financials, crypto, and economic events while providing easy-to-use guides explaining how prediction markets work. Its straightforward format makes FanDuel Predicts an approachable option for users who are new to event-contract trading.

Gemini Predictions is a strong option for users who already trade crypto and want prediction markets within the same platform.

This makes Gemini particularly convenient for crypto-focused traders who also want access to event contracts.

8. OG.com – best for research tools

Frank AmmiranteMy expert take

OG.com stands out for OG Alpha, an AI assistant built directly into the app to help users research live markets, understand contract pricing, and review their existing positions. The platform also covers sports, politics, economics, crypto, technology, culture, and climate. I like OG.com for users who want built-in research tools alongside the standard prediction-market trading experience.

9. Plus500 – best for futures traders

Frank AmmiranteMy expert take

Plus500 is a strong prediction market option for users who already have experience trading futures or other financial products. Prediction markets are integrated into the Plus500 Futures platform, providing access to regulated event contracts alongside traditional futures markets. This makes Plus500 particularly appealing to traders who prefer accessing prediction markets through an established derivatives trading platform rather than a standalone prediction app.

10. Fanatics Markets – best for ongoing rewards

Frank AmmiranteMy expert take

Fanatics Markets stands out for its rewards program and broad event selection. Eligible users can earn FanCash as they trade, whether a position wins or loses, and use those rewards on future trades or elsewhere in the Fanatics ecosystem. The platform also covers sports, crypto, politics, culture, and economics, making it a strong option for users who want variety alongside ongoing rewards.

11. PrizePicks – best for combining team and player picks

Frank AmmiranteMy expert take

PrizePicks stands out because eligible users can combine one Team Pick with 2-5 Player Picks in the same Power Play lineup. Team Picks cover game winners, spreads, and totals. There are separate Culture Picks that expand the platform into politics, crypto, music, movies, and other real-world topics. That makes PrizePicks a strong option for users who already enjoy its fantasy-style Player Picks experience.

What are prediction markets?

Prediction markets let users trade contracts based on the outcome of a future event. Most use Yes/No contracts, with prices moving according to market sentiment instead of fixed odds set by a sportsbook.

For example, if a contract on the Yankees beating the Blue Jays trades at $0.60, the market is implying roughly a 60% chance of that outcome. If the prediction is correct, the contract settles at $1.

Prediction market apps act as exchanges, connecting buyers and sellers. They allow users to enter or exit positions before settlement. Popular markets include sports, elections, economics, crypto, weather, entertainment, and other real-world events. The best prediction market platforms stand out through strong liquidity, competitive pricing, broad market selection, and clear settlement rules.

How do prediction market apps work?

Prediction market apps facilitate trading by matching buyers and sellers rather than having users bet against a sportsbook. This makes liquidity important, as more active markets make it easier to enter or exit a position at a competitive price.

Contract prices also indicate the market's implied probability. For example, a Yes contract trading at $0.70 suggests the market sees roughly a 70% chance of that outcome occurring.

Illustrative example · not live prices

What does a Yes contract cost?

Imagine a contract on the Yankees beating the Blue Jays. Move the price to see how the cost and potential return change.

Cost for 10 contracts
$6.00
Payout if Yes wins
$10.00
Profit if Yes wins
$4.00

If No wins, the payout is $0 and you lose the amount paid. This example excludes fees.

Explore current prediction markets →

Prices continually change based on supply, demand, trading activity, and new information. Many prediction apps display bids, asks, volume, and price history, giving users greater visibility into how contracts are being valued than traditional sportsbook odds.

Traders can often sell positions before an event ends. Once the outcome is known, the platform resolves the contract according to its published rules and designated settlement source.

List of prediction markets

Prediction market apps now let you trade on almost anything, from sports and elections to Bitcoin prices, company performance, and weather. Most leading prediction platforms also highlight trending markets so you can quickly see which events are attracting the most activity. In general, the best prediction markets to trade are those you understand well and have researched before taking a position.

Sports

Sports are among the most popular prediction market categories. You can trade contracts tied to NFL, NBA, MLB, NHL, and college sports, including game winners, point spreads, totals, and futures. Some platforms also offer markets on championships, player awards, and other season-long outcomes.

Politics

Political prediction markets cover major elections odds and government events. Common options include presidential races, midterm elections, individual congressional contests, government shutdowns, legislation, and key votes. These markets can react quickly to polling, debates, endorsements, economic data, and breaking political news.

Crypto

The crypto prediction markets let you trade on future cryptocurrency prices and market movements. Bitcoin and Ethereum are the most common assets, with contracts based on whether a coin will reach a specific price by a certain date, finish above or below a particular level, or experience a major market move.

Economics

Economic markets focus on data and decisions that can influence financial markets. Popular contracts include Federal Reserve interest-rate decisions, inflation readings, GDP growth, and unemployment figures. These markets can be useful for traders who closely follow economic reports and monetary policy.

Entertainment

Entertainment prediction markets cover outcomes across television, music, movies, and celebrity culture. You may find contracts on award winners, Netflix rankings, music charts, reality show results, and major celebrity events. These markets tend to be driven by public interest, industry reporting, and audience trends.

Weather and other events

Prediction platforms also offer markets on weather, technology, and business events. Weather contracts can include temperature records, snowfall, hurricanes, climate events, and seasonal forecasts. Other markets may cover company earnings, mergers and acquisitions, executive changes, SpaceX launches, AI releases, product launches, and other major developments.

How to choose the best prediction apps: our ratings criteria

We rate prediction market apps on the features that have the biggest impact on trading, including liquidity, market selection, fees, payouts, and usability. Liquidity deserves extra weight because prediction markets depend on active buyers and sellers to produce competitive prices and smoother trading. The best prediction apps combine deep markets with transparent costs, reliable settlement, fast payments, and a consistently strong overall user experience.

Market types and liquidity

We look for platforms with a broad selection of contracts and enough trading activity to support competitive pricing. Kalshi stands out for offering markets across sports, politics, economics, crypto, culture, and more. Strong liquidity can create deeper order books, tighter bid-ask spreads, and more opportunities to enter or exit positions efficiently. Kalshi stands out in this regard as well.

Pricing, fees and spreads

Trading costs can have a major impact on overall value. We compare transaction fees, maker and taker charges, and bid-ask spreads while checking how clearly each platform explains its pricing. Novig currently charges no maker or taker fees on pregame straight trades, while ProphetX charges 2% of net gains on straight markets.

Funding ease and payout speed

We consider deposit methods, verification requirements, withdrawal restrictions, and processing times. The best apps support convenient banking options without unnecessary delays. Kalshi offers ACH, debit cards, PayPal, Venmo, crypto, and wires for eligible US users. Crypto withdrawals typically arrive within 30 minutes after eligible crypto funding, while debit-card withdrawals generally arrive within a few hours.

Contract clarity and settlement process

Every contract should clearly state what must happen for it to settle Yes or No. We evaluate settlement rules and how quickly payouts are credited. Clear resolution criteria are especially important for elections, economic data, weather, and other markets where specific wording can determine the outcome.

Security, regulation and licensing

We prioritize platforms operating within the US federal derivatives framework. The exchanges behind Kalshi, Polymarket US, ProphetX, and Novig are CFTC-designated DCMs, and we check the registration status of every platform we list. We also consider identity verification and account security.

User experience

We test desktop and mobile usability, registration, placing and managing trades, market search, portfolio tools, and customer support. FanDuel Predicts stands out for its beginner-focused educational guides, while OG.com differentiates itself with OG Alpha, an AI assistant designed to help users research markets and understand their positions.

Bonuses and promos

We compare welcome offers, trading credits, referral rewards, and ongoing promotions based on their overall value and usability. We also check minimum deposits or trades, expiration dates, withdrawal restrictions, and other terms. A large headline bonus is less valuable if the credits are difficult to use or expire quickly.

How sports trading works in prediction markets

Sports prediction markets work differently from traditional sportsbooks. Instead of placing a wager at bookmaker-set odds, users trade Yes/No contracts through an exchange. Contract prices are driven by supply, demand and trading activity, and can change as new information emerges. Sports prediction apps typically offer game winners, spreads, totals, player outcomes and futures, with users often able to buy or sell positions before settlement.

What to expect

  • ▸Exchange-style trading: Sports prediction markets usually use Yes/No contracts rather than traditional sportsbook odds.
  • ▸Prices reflect probability: Contracts typically trade from $0.01 to $0.99. A Kansas City Chiefs Yes contract at $0.65 implies roughly a 65% market probability.
  • ▸Multiple sports markets: You may find game winners, spreads, totals, player props, futures, and multi-event combinations.
  • ▸Trade before settlement: Depending on the platform and market, you can buy more, sell, or exit a position before the event resolves.
  • ▸Prices move constantly: Injuries, lineup news, and game developments can quickly change contract prices.

Prediction market apps vs traditional sportsbooks

Markets

Sportsbooks generally offer more bet types within individual games, including alternate lines, props, and same-game parlays. Prediction apps may offer fewer options per event but typically cover a wider range of markets beyond sports, including politics, economics, crypto, weather, culture, and technology.

Odds

Sportsbooks set and adjust odds while incorporating a bookmaker margin. Prediction-market prices are primarily determined by buying and selling activity, with contract prices reflecting the market's implied probability.

Transparency

Prediction exchanges often display bids, asks, volume, price history, and order-book depth, giving traders insight into how prices are formed. Sportsbooks generally display the available odds without the same exchange-style order-book data.

Regulation

Legal sportsbooks are primarily regulated under state or tribal gaming laws. Federally regulated prediction-market exchanges operate under commodities and derivatives law and are overseen by the CFTC.

Fees, spreads, and liquidity on prediction market apps

Trading costs can vary significantly between prediction market apps, so it is important to look beyond the price of a contract. We evaluate trading fees, bid-ask spreads, and liquidity to understand the overall cost of trading. Highly liquid markets generally support tighter spreads, while costs can also depend on the platform, contract price, market type, and funding or withdrawal method.

Prediction trading fees

Prediction market fee structures vary considerably. Some platforms charge a fixed fee per contract, while others use price-dependent maker and taker fees, charge a percentage of trading profits, or incorporate certain costs into quoted prices. Some trades may also be fee-free.

Your total cost can depend on the contract price, market type, whether you enter and exit before settlement, and payment-related fees. The bid-ask spread can also create an indirect trading cost. For example, Kalshi uses a price-dependent fee formula, while Polymarket charges a price-dependent taker fee and offers maker rebates. ProphetX charges 2% of net gains on straight markets.

How the bid-ask spread impacts price

The bid-ask spread is the difference between the highest price a buyer will pay and the lowest price a seller will accept. A wider spread can increase trading costs, especially if you want to exit a position early and must accept a less favorable price to sell quickly.

Tighter spreads often indicate stronger liquidity and more agreement around a contract's market value. This can make it easier to enter and exit positions without giving up as much value. When comparing prediction markets, look for active markets with good order-book depth and relatively narrow bid-ask spreads.

Liquidity in prediction markets

Liquidity refers to the amount of money, trading activity, and participation in a market. A liquid prediction market has more active buyers and sellers, making it easier to enter or exit a position without significantly moving the price.

Higher liquidity often leads to tighter bid-ask spreads and more efficient pricing because there is more competition on both sides of the market. This can help contract prices better reflect the market's current view of an outcome's probability.

Low-liquidity markets can have wider spreads, fewer available orders, and greater price slippage. Strong liquidity therefore makes trading easier and can reduce the cost of buying or selling positions.
