“Prediction market” is the useful umbrella term, but these nine accounts do not all work the same way. Some give you a direct exchange account. Others put event contracts inside a sportsbook-style, fantasy or brokerage app and may route trades to more than one exchange.
The brand matters less than the trade in front of you. Check whether the market is available in your state, how many contracts can fill at the quoted price, what fees apply, who sets the settlement rules and whether there is a real buyer if you want to sell.
This list is not a ranking. Use it to find the accounts that fit what you want to trade, then open the individual reviews for the costs, banking rules, exits and customer evidence that can change the decision.
Nine U.S. Prediction Markets to Compare
The order is alphabetical, not a ranking. Each card tells you why the account belongs on a shortlist and what can make it the wrong choice for a particular trade.
DraftKings Predictions
Best fit: DraftKings users who want game lines, player markets, live trading, eligible Combos and non-sports events in a familiar interface.
What is different: Predictions has its own wallet, and the contract can come from different listing exchanges. The sportsbook account, balance and bet protections do not automatically carry over.
Check before opening: The fee shown on the trade slip, the exchange behind the contract, the available exit and the separate withdrawal route.
Fanatics Markets
Best fit: Existing Fanatics customers who want sports-focused event trading, player markets, live contracts and eligible Combos alongside FanCash rewards.
What is different: The account sits inside the Fanatics app, but the underlying exchange supplies the contract and settlement rules.
Check before opening: The complete trade fee and whether the reward has cash value. FanCash can be useful inside Fanatics, but it is not the same as withdrawable profit.
Kalshi
Best fit: Someone who wants one general-purpose account for sports, politics, economics, weather and other event contracts.
What is different: Kalshi operates the exchange and clearing infrastructure behind its direct account. Limit orders give you control over the most you will pay, although an order can remain unfilled.
Check before opening: State and category access, the quantity available at your price, the spread and whether you can sell without depending on support to solve a time-sensitive problem.
NoVig
Best fit: Sports bettors comparing pregame singles, especially individual-game straight trades.
What is different: NoVig charges no trading fee on qualifying pregame individual-game singles. That creates a clean cost advantage only when the available contract price is also competitive.
Check before opening: Live, futures and parlay pricing, available trading volume, the usable exit price and the withdrawal process. The fee-free headline does not apply to every product.
OG
Best fit: Customers who want sports and non-sports event contracts with dollar funding and optional access through the wider Crypto.com account system.
What is different: The product supports market and limit orders, with separate maker and taker treatment. Existing Crypto.com customers have the clearest convenience advantage.
Check before opening: The trading charge, the funding route, any deposit or withdrawal hold and which Crypto.com or OG product the terms actually describe.
Polymarket US
Best fit: Traders who want sports, election and other event markets with control over the price they are willing to pay.
What is different: Polymarket US is a regulated U.S. exchange with its own account, fees and catalogue. It is not the same product as the international Polymarket site.
Check before opening: Use only the U.S. rules when evaluating the account. Confirm the fee, available quantity and executable cash-out rather than relying on a displayed portfolio value.
ProphetX
Best fit: Sports-first traders who want to compare singles, propose their own price and use a desktop exchange as well as mobile apps.
What is different: ProphetX is built around trading sports outcomes against other participants rather than reproducing a standard sportsbook bet slip.
Check before opening: The commission model for the exact product. Straight markets, parlays and some sports can use different calculations, so compare net profit rather than the headline quote.
Robinhood Event Contracts
Best fit: Existing Robinhood customers who want event contracts beside their investing account and prefer one app over several direct exchange accounts.
What is different: Robinhood is the broker. The contract can come from one of several partner exchanges, and that exchange supplies the market and settlement rules.
Check before opening: Trading is mobile-only, approval is separate from an ordinary investing account, and the total fee can change with the exchange route.
Underdog Predictions
Best fit: Underdog users who want team and player contracts inside the same app they already use for Fantasy.
What is different: Prediction Picks and Fantasy entries can appear in the same interface, but they are not the same product. Mixed entries can also use a different payout structure.
Check before opening: Confirm whether the slip is a Prediction, Fantasy entry or Combo; then check the exchange, fee, settlement rules and cash-out terms for that exact entry.
Check Your State Before You Compare Accounts
A national app can still restrict sports contracts, a particular event category or all trading where you are physically located. Legal disputes and practical access are related, but they are not the same question.
Which Providers Can You Actually Use?
Check the providers and sports-market access currently listed for your state. An account may be available while one category inside it is blocked, and access can change without the brand disappearing nationwide.
What Is the Legal Position in Your State?
Review state laws, regulator actions, court disputes and provider-specific restrictions separately from the app’s signup screen. Federal regulation does not prevent every state from challenging sports event contracts.
What Actually Changes From One Platform to Another
Two apps can offer the same team at nearly the same price and still give you different costs, exits and settlements.
The Brand May Not Be the Exchange
The app can take your order while a separate exchange lists the contract and decides the result. Find both names. The exchange rules matter when a game is canceled, a player does not participate or a result is corrected.
The Contract Price Is Not the Full Cost
A 50¢ quote can become a 52¢ effective cost after fees. Add purchase charges, the spread, funding costs and any selling fee before comparing the trade with another market or sportsbook.
The Best Quote May Cover Only a Few Contracts
Check how much is available at each price. If your order consumes several levels of the book, the average cost matters more than the first number shown beside the market.
A Position Value Is Not a Cash-Out Quote
The app can display a profit while no buyer is available for your full position. An exit is real only when the sale can execute at the quantity and price you are willing to accept.
“Void” Does Not Always Mean a Full Refund
Some contracts use a fair-value settlement when the normal outcome cannot be determined. That payment can be less than your purchase cost. Read the cancellation and nonparticipation rules before trading.
A Familiar Login Can Still Mean a Separate Wallet
Sportsbook, fantasy, investing and prediction products may share a username while keeping balances, verification, withdrawals and promotions separate. Confirm where the money will sit before depositing.
A Faster Way to Choose a Prediction Market
You do not need to compare all nine accounts every time. Eliminate the ones that fail the first two checks, then price the same trade at the remaining options.
Check State and Category Access
Confirm that the provider accepts customers in your state and that the sports or event category you want is available there.
Do this before comparing bonuses, fees or app features.
Find the Exact Contract
Match the team, player, line, period and settlement terms. Similar-looking contracts are not interchangeable when one includes overtime or uses a different threshold.
Read the market rules before treating two prices as a comparison.
Compare the Complete Order
Use the quantity you intend to buy. Include the average fill price, entry fee and any funding cost.
Compare the expected net profit, not the cleanest contract price.
Check the Exit and Withdrawal Route
Decide whether you will hold to settlement or may need to sell. Then check withdrawal clearance, supported methods and any separate wallet restrictions.
Do not make a quick exit essential unless the market has enough buyers.
Where to Start Based on What You Want
These are shortlists, not automatic winners. The available price and contract rules still decide the individual trade.
A Broad Event Catalogue
Start with Kalshi and Polymarket US. Add OG, DraftKings Predictions and Fanatics Markets when you want sports plus politics, economics, crypto or cultural events in a familiar consumer app.
Pregame Sports Singles
Check NoVig first for qualifying fee-free pregame individual-game trades. Compare ProphetX when posting your own price or using a sports-first exchange matters. Then price the same selection elsewhere.
A Familiar Sports App
DraftKings Predictions, Fanatics Markets and Underdog Predictions reduce the learning curve for customers already using those brands. Convenience does not establish the best fee or payout.
One Investing and Event App
Robinhood is the natural comparison for existing brokerage customers. Its convenience comes with exchange-specific fees and rules, and trading is not available through the desktop site.
Control Over the Entry Price
Compare Kalshi, Polymarket US, ProphetX and OG when limit or price-controlled orders matter. A better requested price has no value until another participant fills it.
Player Markets and Combos
DraftKings, Fanatics, Polymarket US, OG and Underdog deserve comparison. Read the treatment of an absent player, canceled leg or unresolvable selection before treating the Combo like a sportsbook parlay.
Exchange Account or App Access?
“Prediction market” describes the product category. “Exchange,” “broker” and “app” describe different parts of the trade.
Direct Exchange Accounts
A direct account can give you clearer access to the exchange’s own order types, fee schedule and rulebook. Kalshi, NoVig, Polymarket US and ProphetX are the clearest sports-relevant examples in this list.
Direct access does not guarantee the best price, deepest market or fastest withdrawal. It simply removes one layer between you and the exchange.
Consumer App or Brokerage Access
DraftKings, Fanatics, Robinhood and Underdog bring event contracts into an account customers may already understand. OG connects the product with a wider Crypto.com account system.
That convenience can add a separate wallet, broker charge, rewards layer or exchange route. Read both the customer agreement and the listing exchange’s contract rules.
Prediction Market Red Flags
Most bad account choices begin with one of these shortcuts.
You Compared Cents but Not Fees
A 49¢ contract is not cheaper than a 50¢ contract when the first trade carries enough additional cost to erase the difference.
You Cannot Name the Listing Exchange
If the app and exchange are different companies, you need to know which rulebook decides the outcome and which fee schedule applies.
The App Shows Value but No Sale Quote
An estimated position value is not withdrawable money. Check whether your full quantity can actually sell before counting the gain.
International Terms Are Being Used for a U.S. Account
Polymarket US and the international Polymarket platform are separate products. Other brands can also have several account types with different rules.
Fantasy and Prediction Entries Are Being Blended
A fantasy pick, event contract and mixed Combo can have different payouts and void treatment even when they appear in the same app.
You Funded the Account Before Checking Your State
An account can accept registration while restricting the market you intended to trade. Check access and legal status before moving money.
U.S. Prediction Market FAQs
Are all prediction markets exchanges?
No. Prediction market is the umbrella term for the product. Some brands operate the exchange that lists the contract. Others provide a broker, app or customer account that sends the order to a separate exchange.
Are these prediction markets available in every state?
No. Provider access, sports-market access and non-sports categories can differ by state. Check current availability and legal status before opening or funding an account.
Does CFTC regulation mean every state accepts sports contracts?
No. Federally regulated exchanges and intermediaries still face state challenges, restrictions and litigation over sports event contracts. Federal registration and state acceptance answer different questions.
Is a 50¢ contract the same as even-money sportsbook odds?
Before fees, a 50¢ contract that pays $1 for a win risks 50¢ to make 50¢. That matches the basic return of even money. Trading fees, quantity, spread and settlement rules can make the actual deal different.
Which prediction market is best for sports?
There is no permanent winner. NoVig deserves an early check for qualifying pregame singles; ProphetX is useful for sports-first price control; familiar apps can offer stronger live, player or Combo selections. Compare the exact market and net return.
Can I sell every position before the event ends?
No. The market must remain open, and another participant must be willing to buy the quantity you want at an acceptable price. A cash-out button or portfolio value does not guarantee an executable sale.
Do I need cryptocurrency to use a prediction market?
No. The U.S. accounts in this list support dollar-based trading. OG can also suit customers who want to use supported crypto funding, but cryptocurrency is not required for an ordinary dollar-funded prediction trade.
Is Polymarket US the same as the international Polymarket site?
No. Polymarket US has its own regulated exchange, account system, fees, market catalogue and terms. Do not use international-platform instructions to judge a U.S. trade.
What should I compare before opening a second account?
Check whether the second provider adds a better executable price, a market you cannot get elsewhere, useful order control or a practical payment method. Another logo is not useful by itself.
Should I choose the platform with the lowest fee?
Not automatically. A zero-fee trade can still be worse when the contract price is higher or the available quantity is thin. Compare the complete order and expected net profit.
Compare the Trade, Not Just the Brand
Start with the accounts available in your state. Eliminate the ones that do not carry the exact market you want. Then compare the quantity you can buy, the full cost, the settlement rules and the exit you could actually execute.
A familiar app can be the right choice. So can a direct exchange. The answer is in the order ticket and contract rules, not the size of the brand.
