Prediction markets let you trade on real events, such as election results, sports games, interest-rate moves, and crypto prices.
Each contract reflects a simple question: will a stated outcome happen or not? Prices usually sit between $0.01 and $0.99, which can show how likely traders believe an outcome may be.
The best prediction market apps differ in fees, available markets, payout speed, legal access, and payment options. Our guide breaks down the details that matter before you risk money.
Top Prediction Market Apps
Each app takes a different route to event contracts. Read the rules, fees, and availability before you put money into any position.
1. Polymarket
Polymarket suits people who follow fast news and like a large choice of event contracts. It lists markets across sports, crypto, finance, politics, economics, culture, weather, and tech.
Prices move as orders enter its order book, so you can buy Yes or No shares or sell before resolution.
Limit orders let you set a maximum price rather than accept the current quote. Sports markets use taker fees that peak at an effective 0.75% near 50 cents.
Geopolitics markets carry no fee. Small or unusual markets can show less depth, which may create a larger gap between buy and sell prices.
U.S. readers should note: Polymarket US is a CFTC-regulated exchange, while its international platform uses another entity.
Read each market’s resolution rules before you place a position.
Main Features
- Broad event categories
- Limit-order price control
- Fee-free geopolitics markets
2. Crypto.com
Crypto.com suits app users who already keep cash or crypto in the same account. Its Prediction product lists contracts across sports, politics, economics, financial markets, and culture.
You can fund a position with cash or convert crypto first, then buy contracts that usually cost between one cent and 99 cents.
Crypto.com says users can start with $10, open more than one contract for a single outcome, and exit before settlement to lock in part of a gain or limit a loss.
Crypto.com | Derivatives North America offers the product through a CFTC-regulated exchange.
Jurisdiction rules still apply, so check the app before you deposit. New users who do not use crypto may need extra time to learn the account options.
Main Features
- Cash or crypto funds
- Early contract exit
- $10 starting amount
3. ProphetX
Sports fans who know American odds may find ProphetX easy to read. Its order book lets users take positions before a match or in live play. Its menu centers on major U.S. leagues, international events, game winners, and player props.
Limit orders give you control over the price you accept, which helps after lineup news or injury reports. ProphetX also offers parlays with no fee on net profits.
Its non-sports menu is smaller than broad event platforms. Newer markets may have fewer open orders than major rivals, which can affect price quality.
Check the order book rather than a headline price before you place a contract. Price gaps can still appear.
Main Features
- American odds display
- Live sports contracts
- No-fee profit parlays
4. Kalshi
Kalshi offers a simple route into event contracts for people who prefer dollars over crypto. It lists Yes and No markets tied to sports, elections, weather, economic reports, policy, and major news.
Each market has clear rules that explain the result source and settlement date, so take time to read them before you buy.
Kalshi operates as a CFTC-regulated Designated Contract Market in the United States and requires account checks before users can access the exchange.
Contract prices show the market’s implied chance of each outcome. Fees vary by market and order type, so confirm the total before you submit a trade.
Kalshi suits users who value clear rules and a familiar cash-based account. Market choice can feel less broad for niche culture and entertainment topics.
Main Features
- CFTC-regulated U.S. exchange
- Cash-based event contracts
- Published market rules
5. OG
OG takes a more social route than most event-contract apps. Live chat and public leaderboards let users follow active markets and compare results with other account holders.
Its contract list covers sports, politics, economic data, finance, crypto, climate, culture, and major news.
You buy a contract at a price that reflects the market’s view of an outcome, then receive the set payout if the result supports your position.
OG Prediction Markets operates through a Crypto.com affiliate with CFTC registration as a designated contract market.
Social tools can make a busy market feel more active, yet they should never replace your own research.
Less popular markets may have fewer orders, which can make entry and exit prices less attractive. Keep trade sizes modest.
Main Features
- Live chat
- Public leaderboards
- Sports and culture contracts

How to Choose a Prediction Market App
The right app depends on the markets you follow, how you fund your account, and the rules in your location. Use the points below to compare the options before you risk any money.
Market Range
Start with the events you actually follow. Sports-first apps suit match results, player props, and live contracts.
Broader apps add elections, inflation reports, weather, crypto prices, and major news. A larger menu sounds useful, yet inactive markets can have poor prices. Pick an app with enough contracts in topics you understand.
Fees and Limits
Check every cost before you enter a contract. Some apps charge a fee when you take an order, while others include the cost inside the price.
Review minimum deposits, withdrawal rules, and any cap on position size. A five-cent fee can matter when you buy many low-priced contracts during a busy week.
Legal Access
Legal access matters as much as the market list. Some services accept only adults in approved U.S. states, while others operate outside the country through separate entities.
Account checks can require an ID, home address, and payment details. Read the terms before you transfer funds, because restrictions can change across states and countries.
Market Liquidity
Look at the gap between the buy price and sell price before you place an order. Busy contracts often let you buy or sell near the displayed quote.
Quiet contracts can force you to accept a worse price or wait for another user. Limit orders give you more control in those cases.
Payout Rules
Read the exact question and settlement source before you buy. A contract can resolve through an official report, a league result, a government release, or a named news outlet.
Small wording differences matter. Check the closing date too, since some contracts settle minutes after an event while others stay open for weeks.
Frequently Asked Questions
What Is A Prediction Market App?
Prediction market apps let users buy contracts tied to a clear outcome. A Yes contract pays a fixed amount after a correct result, while a No contract pays if the stated outcome does not happen. Contract prices reflect market opinion.
Are Prediction Market Apps Legal?
Legal access depends on your country, state, and the platform’s licence. Some U.S. apps operate under CFTC oversight, while other services use separate international products. Check local rules and each app’s terms before you deposit money.
Can I Sell Before A Market Settles?
Most prediction market apps let you sell a contract before the final result. For example, a 40-cent Yes contract may rise to 70 cents after key news. A sale at that point gives you a gain before settlement.
How Much Money Do I Need To Start?
Minimum amounts vary by app, payment method, and contract price. Some platforms allow positions for only a few dollars, yet a small start still carries risk. Set a limit, do not pursue losses, and treat contracts as money you can lose.
