How to Trade Prediction Markets: A Beginner’s Trading Guide
Learning how to trade prediction markets can take some time, especially if you’re new to this burgeoning industry. This guide breaks down the mechanics so you can trade confidently across any of our top prediction market operators.
Here’s what we’ll cover (click below to jump to the specific section):
- How contracts are priced
- Buying Yes vs. No positions
- Placing a trade and reading the order book
- Entering and exiting a position
- Settlement and fees
- Liquidity risks
- Common first-time trader mistakes

How Prediction Market Contracts Are Priced
Every prediction market runs on binary event contracts: Yes and No. Both sides price between $0.01 and $0.99. You’ll see this shown as cents (55¢), a percentage, or on a $0-$100 scale.
On Crypto.com Predictions, our reference platform for this example, pricing defaults to the $0.01-$0.99 range, with a percentage chance listed next to each side.
Take the Video Game of the Year 2026 market. Grand Theft Auto’s Yes position trades at $0.78, with No priced at roughly $0.22. That’s about a 78 percent implied probability, making it the heavy favorite.
Prices are set by buyers and sellers agreeing on a number:
- Bid: the highest price a buyer will pay
- Ask: the lowest price a seller will accept
When a bid and ask match, a trade happens, and that sets the contract’s new price.
Example: If the best bid is $0.65 and the best ask is $0.69, the midpoint is $0.67, which most platforms display as a 67 percent implied probability.
Buying Yes and No Contracts
Both sides of a contract can be bought or sold.
- Buy Yes: you’re betting the event happens.
- Buy No: you’re betting it doesn’t.
If Yes trades at $0.67, No trades at roughly $0.33. Before fees, both sides typically add up to $1.00.
Here’s a common mix-up for beginners: buying a No contract is not the same as selling a Yes contract you already own.
- Buying No opens a new position against the outcome.
- Selling Yes closes a position you already hold.
So if you own Yes contracts and change your mind, you’ve got two options:
- Sell your Yes contracts to exit.
- Buy No contracts to open an opposing position.
These lead to different outcomes once the event resolves.
Placing a Trade: Order Types and the Order Book
You’ve got two order types to work with:
- Market order: executes immediately at the best available price.
- Limit order: you set your price and wait for a match.
The order book is just a running list of buy and sell orders sitting at different price levels:
| Price | Buy Orders (Bids) | Sell Orders (Asks) |
|---|---|---|
| $0.68 | — | 1,200 |
| $0.66 | — | 800 |
| $0.64 | 950 | — |
| $0.62 | 1,500 | — |
Sellers here are asking $0.66 or more. Buyers are bidding $0.64 or less. So a market order to buy fills at $0.66, the lowest available ask. A $0.65 limit order would sit and wait until a seller comes down to meet it.
Entering and Exiting a Position
Let’s build a hypothetical trade.
You buy 100 Yes contracts at $0.54 each. Total cost: $54, before a small exchange fee.
From here, you’ve got two ways to exit:
- Sell before settlement. If the price rises to $0.65, you sell your 100 contracts for $65, an $11 gain before fees. No need to wait for the outcome.
- Hold until settlement. If the event happens, your contracts resolve at $1.00 each, a $100 payout and $46 gain before fees. If it doesn’t happen, they resolve at $0.00, and you lose your full $54 stake.
You’re never required to hold until settlement. You can exit at the current price any time the market’s open, though fees apply on early exits and vary by operator.
Exiting early is built into how prediction markets work, since you sell to another trader at the current market price. Sportsbooks offer cash-out on some bets, but the sportsbook sets that price, and it isn’t available on every wager.
How Settlement Works
Markets settle once the underlying event’s outcome is confirmed, automatically resolving all open contracts.
- Yes pays $1.00 if the outcome happens, $0.00 if it doesn’t.
- No pays $1.00 if the outcome doesn’t happen, $0.00 if it does.
You don’t need to do anything to trigger settlement. It happens automatically once the outcome can be confirmed, either through regulated data providers or decentralized dispute processes, depending on the platform. Look for the source listed in the event description below the timeline.
Fees in Prediction Market Trading
Fee structures can catch new traders off guard, and they vary a lot by platform.
On many exchanges, including Kalshi, trading fees are calculated from the contract price and peak when a contract trades near $0.50, then shrink toward the $0.01 and $0.99 extremes. There’s no flat percentage across the board.
You’ll typically run into:
- Exchange fees
- Technology fees
- Withdrawal fees
Some platforms take a cut of net profit at withdrawal instead of charging per trade, a real difference in how operators structure costs.
On Kalshi, taker fees range from $0.07 to $1.75 per 100 contracts. Maker fees run smaller, between $0.02 and $0.44.
Liquidity and Why It Matters
Liquidity determines how easily you can get in and out of a position.
Popular events (Super Bowl, presidential elections) draw heavy volume and deep order books. Niche markets often don’t, and that creates problems for both buyers and sellers.
In thin markets:
- Market orders can fill at much worse prices than the last trade.
- Exiting early gets harder since there aren’t enough buyers on the other side.
- Slippage and wide spreads become common, adding risk to every position.
A trader stuck in a low-liquidity market may have no choice but to hold until settlement. And since there’s no bookmaker or house edge on a peer-to-peer exchange, it only takes a few coordinated traders to move the price significantly.
Understanding the Risk
Trading prediction markets means accepting real financial risk. A position can lose all its value if the outcome doesn’t go your way.
Discipline matters here. This is a volatile form of entertainment, not a reliable income source for most people. Only trade with money you can afford to lose.
Being CFTC-regulated doesn’t mean risk is mitigated, especially with the liquidity issues we just covered.
A recent study on Polymarket traders found 56 percent of accounts lost money over a six-week span: 32 percent lost less than $100, and 24 percent lost $100 or more. Only 18 percent of traders profited more than $100. The numbers speak for themselves.
Common Mistakes First-Time Traders Make
- Confusing buying No with selling Yes. These are different actions with different outcomes.
- Skipping the order book before a market order. Low liquidity means slippage and wider spreads than expected.
- Assuming confidence beats the market. The price reflects everyone trading, not just your opinion.
- Not knowing you can exit early. Holding until settlement isn’t required, and it can backfire.
- Ignoring fees when estimating profit. Exchange, trade, and withdrawal fees all cut into returns. Read the terms first.
- Trading money you need elsewhere. You could lose your full stake. Don’t deposit funds earmarked for other expenses.
- Assuming rules are the same everywhere. Fee structures, minimum trade size, and settlement timelines all vary by operator. Check our reviews first.
Types of Prediction Markets to Trade
Most platforms offer eight or more market categories. Here's a quick rundown.
🗳️ Politics
Trade election results, confirmation votes, and policy decisions at the state and federal level, down to specific bills. High liquidity thanks to massive trading volume. See our Political Prediction Markets guide.
🏈 Sports
Moneyline, totals, run lines, and player props, with some platforms allowing parlay-style trading. Prices are set by traders rather than a house, though exchange fees still apply. See our Prediction Markets vs Sports Betting guide.
🔐 Crypto
Trade price movements on major cryptocurrencies like Bitcoin and Ethereum, with contracts ranging from 15-minute to annual settlement windows. Highly liquid. For more insight, see our Prediction Markets vs Crypto Trading guide.
💵 Economic
GDP growth, interest rates, inflation, jobs, recession odds, and rent costs. Still solid volume, but a step down from the categories above.
🍿 Pop Culture
Movies, TV, music, video games, awards, and influencers. Year-end markets like TIME’s Person of the Year draw steady volume as the announcement approaches. See our Pop Culture Events Prediction Markets guide.
☀️ Weather
Rainfall, temperature, and longer bets like whether 2026 ranks among the hottest years on record. Thinner liquidity than most categories.
🎮 Esports
NBA 2K, Madden, FIFA, Counter-Strike, League of Legends, and more. Still a relatively thin market.
💬 Mention
Bet on whether a public figure says a specific word or phrase, common around State of the Union addresses, award speeches, or earnings calls. The category is under CFTC review, and Kalshi pulled its sports-broadcast mention markets in August 2026 while keeping political and earnings call mentions live.
🤖 AI
Contracts tied to company valuations and which AI model releases by a given date. Drier subject matter, but a growing category.
Final Thoughts on Trading Prediction Markets
Trading prediction markets comes down to understanding a few core mechanics: how contracts are priced, when to enter or exit a position, and what fees you’re giving up along the way. None of it requires guesswork once you know how the order book works and what separates a market order from a limit order.
Still, don’t mistake mechanical understanding for an edge. The data on trader outcomes is clear that most people lose money, and liquidity issues can make even a well-reasoned position hard to exit cleanly. Start small, stick to markets with real trading volume, and only risk money you’re prepared to lose. From there, our operator-specific reviews and category guides can help you find the right platform and markets for how you want to trade.

Implied probability is the price of the contract. A 55¢ contract implies a 55 percent probability that the event happens.
A market order executes instantly at the current price. A limit order lets you set your own price and wait for a match.
Yes. Exchange fees and sometimes additional fees apply, and they vary by operator. Check our reviews for platform-specific details.
It varies by operator. See our latest reviews for current minimums on Polymarket, Crypto.com Predictions, DraftKings Predictions, ProphetX, and more.
The biggest difference is pricing. Sportsbooks set odds with a house edge. Prediction markets let traders set the price peer-to-peer. There’s also more incentive to buy and sell before settlement, rather than holding to the end.
