How to Trade Prediction Markets: A Beginner’s Trading Guide
Learning how to trade prediction markets starts with one simple rule: every contract pays $1 if you’re right and $0 if you’re wrong. The price you pay in between tells you how likely the market thinks that outcome is...Read More
This guide walks you through prediction market trading from the ground up. We start with how event contracts are priced, how to buy Yes or No, and how to place your first trade. Then we cover the order book, exiting early, settlement, and fees, before breaking down how each market type trades, from sports and politics to crypto, economics, weather, AI, and mention markets.
Most CFTC-regulated exchanges, like Kalshi and Polymarket, share the same core trading mechanics. Fees, minimum trade size, and settlement time vary by platform, so treat the figures in our examples as illustrations and check your operator’s terms.

How Prediction Markets Work
A prediction market is an exchange where you trade event contracts tied to real-world outcomes: a game result, an election, Bitcoin’s price on Friday, or tomorrow’s high temperature in Chicago. Each contract asks a question with a verifiable answer. If the outcome happens, the contract pays $1.00. If it doesn’t, it pays $0.00.
You aren’t betting against a house. You’re trading with other users, and the platform earns money by charging fees. That peer-to-peer setup is why prices move constantly as new information comes out, and why you can sell your position before the event ends.
Most markets are binary, with one Yes contract and one No contract. Others list several possible outcomes, like a set of temperature ranges or a field of award nominees. In those markets, each outcome trades as its own contract, and the prices across all outcomes add up to roughly $1.00, since exactly one of them has to happen.

How Prediction Market Contracts Are Priced
Prediction market contracts price between $0.01 and $0.99. Depending on the platform, you’ll see that shown in cents (55¢), as a percentage, or on a $0-$100 scale. Whichever format you see, the price doubles as the market’s implied probability: a contract trading at $0.55 means traders collectively give that outcome about a 55 percent chance.
Here’s a real example from Kalshi. On the morning of November 10, 2026, I opened the “Highest temperature in Los Angeles today?” market, which splits the day’s high into six brackets, each with its own Yes and No price. The 84° to 85° bracket was the favorite at 63%, while 82° to 83° and 86° to 87° each sat at 17%. Add up the Yes prices across all six brackets and you get 100%, since exactly one of them has to hit.
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. A couple of minutes later, the 84° to 85° Yes contract had a best bid of 67¢ and a best ask of 69¢, putting the midpoint at 68¢, or roughly a 68 percent implied probability. You’ll also notice Yes at 69¢ and No at 33¢ add up to $1.02, not $1.00. That extra 2¢ is the spread, since No’s 33¢ price mirrors Yes’s 67¢ bid.
Prices move whenever new information changes what traders expect, whether that’s an injury report, a new poll, a forecast update, or a jump in Bitcoin’s price. We cover what moves each market type in more detail further down.
Buying Yes and No Contracts
Every binary market has two sides you can buy:
- Buy Yes: you’re trading on the event happening.
- Buy No: you’re trading on it not happening.
If Yes trades at $0.67, No trades at roughly $0.33. Before fees, both sides add up to about $1.00. Here’s how each position pays out:
| Your Position | If the Event Happens | If the Event Doesn’t Happen |
|---|---|---|
| Buy 1 Yes at $0.67 | Pays $1.00 ($0.33 profit) | Pays $0.00 ($0.67 loss) |
| Buy 1 No at $0.33 | Pays $0.00 ($0.33 loss) | Pays $1.00 ($0.67 profit) |
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 can sell your Yes contracts to exit, or buy No contracts to open an opposing position. These lead to different results once the event resolves, so pick the one that matches what you’re actually trying to do.
How to Place Your First Prediction Market Trade
Platforms look a little different, but the process for placing a trade is nearly identical everywhere.
Choose a Platform and Sign Up
Pick a CFTC-regulated exchange that operates in your state and offers the markets you want to trade. You’ll need to meet the platform’s age requirement and verify your identity before trading. Our best prediction market apps guide compares the leading options.
Fund Your Account
Deposit using a supported method, such as a debit card, ACH bank transfer, PayPal, or crypto, depending on the platform. Minimum deposits are low, often between $1 and $10.
Pick a Market You Understand
Start with a subject you already follow, whether that’s the NFL, the Fed, or the Oscars. Check the trading volume, too. Busier markets are easier to enter and exit at fair prices.
Read the Contract Rules
Every market lists its settlement source, deadline, and exactly what has to happen for Yes to win. Read these before you trade. A contract can resolve differently than you expect if you skip this step.
Choose Yes or No and Set Your Order
Select a side, choose a market order or limit order, and enter how much you want to spend or how many contracts you want. When I entered $5 on Yes for the 84° to 85° bracket, Kalshi showed the projected payout before I confirmed the trade.
Confirm and Manage Your Position
Once your order fills, the position shows in your portfolio with its current value. From there, you can sell any time the market is open or hold until settlement.
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 another trader to match it.
The order book is 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.
Market orders are faster, but in a thin market they can fill at a worse price than you expected. Limit orders give you price control at the cost of speed, and on many exchanges they qualify for lower maker fees. On Kalshi, I set up a limit order for one Yes contract at 68¢, a cent below the 69¢ ask. Since no seller was asking 68¢ yet, the order would sit in the book until one came 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 don’t have to choose all or nothing, either. You can sell 50 contracts to lock in part of a gain and let the other 50 ride to settlement. Kalshi’s cash-out screen makes this easy, with 25%, 50%, 75%, and Max buttons.
Here’s how that looked on my own trade. My $5 order bought 6.87 Yes contracts for a total cost of $4.91, worth $6.87 if the high landed between 84° and 85°. A minute later, cashing out would have returned $4.54, a $0.37 loss, even though the market still gave that bracket a 71% chance. That gap is the spread at work: you buy at the ask and sell at the bid, so an instant round trip almost always costs you a little.
Selling early also works in the other direction. If the price drops to $0.40 and you no longer like the position, selling caps your loss at $14 instead of risking the full $54. Exiting early is built into how prediction markets work, since you’re selling to another trader at the current price. Sportsbooks offer cash-out on some bets, but the sportsbook sets that price, and it isn’t available on every wager.
How Prediction Markets Settle
Markets settle once the event’s outcome is confirmed, and all open contracts resolve automatically:
- 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. What decides the result is the source named in the contract rules, not a TV graphic, a viral clip, or your weather app. That source varies by market:
- Sports: official results and stats from the league or governing body.
- Elections: certified results from state election officials or another source named in the rules.
- Weather: official readings for a specific station, like Kalshi’s Los Angeles temperature markets, which settle on The Weather Company’s figures for the Los Angeles climate station (CLILAX).
- Crypto: a named price index or feed, such as CF Benchmarks’ Real-Time Index or Chainlink.
Some decentralized platforms, including Polymarket on certain markets, resolve outcomes through UMA’s Optimistic Oracle. A proposed result can be challenged and sent to a token-holder vote, which can leave a market unsettled longer than you’d expect. Contract rules also spell out how ties, postponements, and canceled events are handled, so check them before you trade.
Prediction Market Fees and Taxes
Prediction market fees vary a lot by platform, and they can catch new traders off guard. On many exchanges, including Kalshi, trading fees are calculated from the contract price. They peak when a contract trades near $0.50 and shrink toward the $0.01 and $0.99 extremes, so there’s no flat percentage across the board.
You’ll typically run into some combination of:
- Exchange or trading fees
- Technology fees
- Withdrawal fees
On Kalshi, taker fees range from $0.07 to $1.75 per 100 contracts, while maker fees run smaller, between $0.02 and $0.44. Polymarket US charges a taker fee of roughly 0.1 percent. Some platforms take a cut of net profit at withdrawal instead of charging per trade, so compare total costs rather than headline fees.
Taxes are the other cost to plan for. The IRS hasn’t issued definitive guidance on prediction market winnings, so gains may be treated as capital gains or ordinary income depending on the contract. Keep records of every trade and talk to a tax professional about your situation.
Liquidity and Why It Matters
Liquidity determines how easily you can get in and out of a position. Popular events, like the Super Bowl or a presidential election, draw heavy volume and deep order books. Niche markets often don’t, and that creates problems for buyers and sellers alike.
In thin markets:
- Market orders can fill at much worse prices than the last trade.
- Exiting early gets harder since there may not be enough buyers on the other side.
- Slippage and wide spreads become common, adding risk to every position.
Liquidity can also change fast. Spreads on live markets often widen the moment an event starts, since far more traders are reacting at once. A trader stuck in a low-liquidity market may have no choice but to hold until settlement, and with no bookmaker setting the price, a few coordinated traders can move it 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. This is a volatile form of entertainment, not a reliable income source for most people, so only trade with money you can afford to lose.
Being CFTC-regulated doesn’t remove that risk, especially with the liquidity issues we just covered. Prediction markets are also zero-sum: every dollar one trader wins comes from another trader, minus fees.
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.
Types of Prediction Markets and How Each One Trades
Once you know the core mechanics, the next step is understanding how different market types behave. Every category uses the same Yes/No contracts, but what moves prices, how markets settle, and the risks involved change from one to the next. Here’s a quick overview:
| Market Type | Example Contract | What Moves the Price | Typically Settles On |
|---|---|---|---|
| Sports | Will the Bengals win by more than 5.5 points? | Injury reports, lineups, live game events | Official league results and stats |
| Politics | Will Candidate A win the election? | Polls, debates, endorsements, legislative schedules | Certified election results, Senate roll-call votes |
| Crypto | Will BTC trade above $100,000 by Dec. 31? | Exchange price data, volume, regulatory news | A named price index or feed, such as CF Benchmarks |
| Economics | Will the Fed cut rates at its next meeting? | Data releases, Fed commentary, related reports | BLS, BEA, or FOMC releases |
| Pop Culture | Will Film X win Best Picture? | Critic reviews, precursor awards, sales and streaming data | The awarding body, Billboard, Netflix, or Spotify data |
| Weather | Will NYC’s high reach 90°F today? | Forecast model runs, observations | Official readings for a named weather station |
| Mentions | Will the CEO say “AI” on the earnings call? | Event agenda, live remarks | An approved transcript or broadcast, or an oracle |
| AI and Tech | Will a lab release its next flagship model by Dec. 31? | Lab announcements, benchmark results, regulation | The lab’s announcement or a named benchmark |
Sports Prediction Markets
Sports prediction markets turn game outcomes and player performance into tradable event contracts. Game-winner contracts work like a moneyline bet, while spread-style contracts focus on margin of victory (“Will the Bengals win by more than 5.5 points?”). You’ll also find player prop-style contracts, season-long futures, live in-game markets, and esports markets on titles like League of Legends, Counter-Strike 2, Dota 2, and Valorant.
Injury reports and lineup announcements are the biggest price drivers before a game, and live markets swing on every score, penalty, or injury. Contracts settle on official league results and stats, which take priority over TV graphics or live-score apps. The legality of sports contracts is also being contested in several states, so confirm availability where you live before trading.
Political Prediction Markets
Political prediction markets cover election winners and primaries, vote share and Electoral College totals, cabinet confirmations, and whether specific bills pass by a set date. The election calendar drives most of the volume, but confirmations and major legislation can open new markets any time.
Polls, debates, endorsements, candidate withdrawals, and legislative scheduling all move prices. Election markets usually settle on certified results, while confirmation markets settle on the official Senate roll-call vote. Insider information is a known concern in this category, and the US Senate adopted a rule in April 2026 barring senators and their staff from trading prediction markets. Some states also prohibit election betting, so availability varies.
Crypto Prediction Markets
Crypto prediction markets let you trade on outcomes tied to digital assets without owning the coin itself. Price threshold and range contracts on BTC, ETH, SOL, XRP, and DOGE are the most common, with timeframes from five minutes to a full year. Some platforms also list markets on protocol upgrades, crypto ETF approvals, stablecoin de-pegs, and token launches.
Exchange price data, trading volume, regulatory news, and on-chain activity all move prices. The key risk is the settlement source. Crypto prices can differ slightly from one exchange to another, so a contract settles on the specific index or feed named in its rules, not the price on your favorite exchange. That gap matters most during fast moves, like the 2022 TerraUSD collapse.
Economic Prediction Markets
Economic prediction markets turn scheduled data releases and Federal Reserve decisions into Yes/No contracts. Instead of buying stocks or bonds, you trade a specific outcome, like whether CPI inflation tops a set threshold or the FOMC cuts rates at its next meeting. Volume is solid, though a step down from sports, politics, and crypto. The main contract types are:
- CPI and inflation: Headline CPI, core CPI (which excludes food and energy), PCE, and core PCE, usually framed as whether a reading lands above or below a threshold for a set period.
- Jobs and unemployment: Nonfarm payrolls, the unemployment rate, and weekly initial jobless claims.
- Fed rate decisions: Whether the FOMC raises, cuts, or holds its target range at a given meeting.
- GDP growth: Quarterly or annual growth thresholds tied to Bureau of Economic Analysis (BEA) estimates.
- Recession odds: Whether the US enters a recession within a set window, resolving against the definition or source named in the rules.
Prices move hardest the moment a report or FOMC statement drops, but they also drift beforehand as related data comes in. A strong private payrolls report can shift a jobs contract days before the official number, and a hot regional inflation reading can move a national CPI market ahead of the BLS release. These markets have a solid track record, too: a 2026 Federal Reserve working paper found Kalshi's market-implied CPI forecasts had roughly 40 percent lower average error than consensus economist forecasts for headline inflation.
Settlement depends on the source the contract names. CPI and jobs markets typically settle on Bureau of Labor Statistics (BLS) releases, Fed markets on the FOMC statement, and GDP markets on a specific BEA estimate. That last one matters: BEA publishes advance, second, and third estimates each quarter, and a contract that settles on the advance figure won't change if a later revision tells a different story.
Since nearly every economic contract runs on a fixed calendar, you know in advance when prices are most likely to move:
| Release | Source | Schedule | Common Contracts |
|---|---|---|---|
| CPI | BLS | Monthly, usually the second week | Headline CPI, core CPI, year-over-year inflation |
| Employment Situation (Jobs Report) | BLS | Monthly | Nonfarm payrolls, unemployment rate |
| Initial Jobless Claims | Department of Labor | Weekly, Thursday mornings | Weekly claims thresholds |
| PCE Price Index | BEA | Monthly | PCE and core PCE thresholds |
| GDP | BEA | Quarterly (advance, second, and third estimates) | Quarterly growth thresholds |
| FOMC Rate Decision | Federal Reserve | About eight meetings per year | Hike, cut, or hold |
Decide up front whether you're trading the release itself or the run-up to it. A position opened the morning of a jobs report is a bet on the number. A position opened a week earlier is a bet on how expectations will drift before then. Also note that a Fed rate decision trades as an economic market, but a congressional vote on an economic bill is a political outcome.
Pop Culture Prediction Markets
Pop culture prediction markets cover award-show winners (Oscars, Grammys, Emmys), box-office thresholds, music chart positions, streaming rankings, and reality TV eliminations. Year-end markets like TIME’s Person of the Year also draw steady volume as the announcement approaches.
Award markets react to critic reviews, precursor awards, and leaks, while box-office and chart markets move on measurable data like opening-day sales and streaming numbers. Contracts settle on the official source, such as the awarding body, Billboard, or Netflix’s Top 10. Reality TV carries a unique risk: shows are filmed months in advance, so cast, crew, and anyone with a spoiler may know the result while the market is still open.
Weather Prediction Markets
Weather prediction markets cover daily high and low temperatures, rainfall, snowfall, and hurricane formation, intensity, and landfall. Many daily contracts use temperature brackets and settle within 24 hours, while hurricane markets peak during the Atlantic season (June 1 through November 30).
Forecasts drive prices, and major weather models publish new runs four times a day, at 00, 06, 12, and 18 UTC. That predictable rhythm is why automated trading is common here. The biggest risk is settlement-source mismatch. The Los Angeles market I traded settles on The Weather Company’s reading for the city’s climate station, and its rules state outright that sources like AccuWeather and Google Weather don’t count. A single degree can flip a narrow bracket, so don’t rely on your phone’s weather app.
Mention Markets
Mention markets ask whether a public figure will say a specific word or phrase during a defined event, like an earnings call, press conference, or speech. A single event can have a dozen or more separate contracts, one for each word, and they often move independently once the speaker gets going.
The contract rules decide everything here, including whether plurals or related words count and which part of the event is eligible. In a February 2026 Kalshi market on a Bernie Sanders tele-rally, clips appeared to show him saying listed terms, but the contracts resolved No because no approved news source covered the event. Speakers can also influence outcomes by saying or avoiding words on purpose. 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 and Tech Prediction Markets
AI prediction markets let you trade on outcomes in the AI industry itself. That includes when a lab releases its next model, how a model scores on a named benchmark, which model leads usage rankings, and whether a milestone like artificial general intelligence (AGI) arrives by a set date. They're different from AI stock predictions, which forecast a company's share price. They're also different from AI trading bots, which automate trades on other markets. You can find those in our prediction market tools hub.
- Model release dates: Contracts on whether a lab ships a specific model before a cutoff date, often with several cutoffs listed as separate contracts.
- Benchmarks and rankings: Whether a model reaches a score threshold on a named test, or which model ranks highest in a given week.
- AGI timelines: Whether AGI is achieved by a specific year, the most speculative contract type in the category.
- Company milestones: Valuations and similar outcomes for AI companies.
Lab announcements drive most of the price action. If a lab confirms a model has entered final safety testing, a release-date contract can jump well before any launch date is set. Unresolved safety concerns can push a launch past its window right up to the deadline. Benchmark results, regulatory decisions, and new safety requirements move prices too. Be careful with hype: labs often tease models weeks or months early, and a contract only resolves on the evidence its rules require, not on headlines.
Release-date contracts usually settle on the lab's own announcement or release. Benchmark contracts should name the test, the organization running it, and the exact score threshold. AGI contracts are the trickiest because there's no agreed definition of AGI. Kalshi's market on when OpenAI will achieve AGI, for example, resolves on OpenAI's own announcement rather than an independent standard, and another platform may define a similar-sounding contract differently.
Kalshi lists AI markets in a dedicated category within its Science section, and Polymarket runs a standalone AI section. Volume is lighter than sports, politics, or crypto. Contracts also tend to open around major model releases and roll off once they settle, so check each platform's current lineup before you plan a trade.
Prediction Markets vs Sportsbooks, Crypto, and Stock Trading
Prediction markets borrow pieces from sports betting, crypto, and stock trading, but the mechanics differ in ways that affect how much you can lose and how you get out. Here’s how they compare:
| Feature | Prediction Markets | Sportsbooks | Crypto Trading | Stock Trading |
|---|---|---|---|---|
| What You Buy | Event contracts that settle at $0 or $1 | A wager at odds the book sets | Digital assets | Shares of a company |
| Who Sets the Price | Other traders | The sportsbook | The market, 24/7 | The market |
| Built-In House Edge | None; platforms charge fees | Yes, the vig | None; fees and spreads apply | None; spreads and some fees apply |
| Max Loss Per Position | What you paid | Your stake | Your stake, or more with leverage | Your stake, or more with margin or shorting |
| Exit Early | Yes, at the market price | Only where cash-out is offered | Yes | Yes |
| End Date | Fixed resolution date | When the event ends | None | None |
| US Regulator | CFTC | State gaming regulators | Split between SEC and CFTC | SEC and FINRA |
| Tax Treatment | Unsettled | Gambling income | Capital gains (taxed as property) | Capital gains |
Vs sportsbooks: A sportsbook sets the price and builds in a margin, typically 3 to 7 percent. Prediction markets let traders set prices, and the price reads directly as a probability. Sportsbooks still offer deeper sports menus, same-game parlays, and more generous promos, but they’re licensed state by state, while federally regulated prediction markets are available far more widely.
Vs crypto trading: A crypto prediction market contract is a position on an outcome, not ownership of the coin. Your maximum loss is what you paid, while leveraged or short crypto trades can lose more than your stake. Some platforms, including Crypto.com, offer both, but as separate products.
Vs stock trading: Stocks have no expiry and represent ownership in companies that can create long-term value. Prediction markets are zero-sum and resolve on a fixed date. Stocks suit long-term wealth building, while event contracts suit a specific view on a specific event.
Prediction Market Trading Strategies to Try Next
Once you’re comfortable with the basics, these are the habits experienced traders lean on:
- Specialize. Your edge comes from pricing an event better than the crowd, which is hard to do across baseball, inflation, and reality TV at once. Stick to the fields you know best.
- Trade the information calendar. Injury reports, lineup drops, poll releases, economic data, and weather model runs all arrive on predictable schedules. Prices don’t always catch up right away.
- Use limit orders in thin or fast markets. They protect you from slippage when spreads widen, especially as a live event starts.
- Scale in and out. Building or trimming a position in pieces lets you lock in gains without giving up all your upside.
- Hedge outside risks. An investor holding airline stocks could buy Yes on oil topping a set price. If oil spikes, the contract pays out and cushions the stock losses.
- Compare prices across platforms. The same event can trade at different implied probabilities on different exchanges, or against sportsbook pricing.
- Use tools carefully. Analytics dashboards, aggregators, and trading bots can speed up research and execution. Browse our prediction market tools hub, but remember no tool guarantees returns.
Common Mistakes First-Time Traders Make
- Confusing buying No with selling Yes. These are different actions with different outcomes.
- Skipping the contract rules. The settlement source and wording decide the result, not what seems obvious from the news.
- 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, trading, and withdrawal fees all cut into returns.
- Trading money you need elsewhere. You could lose your full stake, so don’t deposit funds earmarked for other expenses.
- Assuming rules are the same everywhere. Fees, minimum trade size, settlement methods, and state availability all vary by operator. Check our reviews first.
Final Thoughts on Trading Prediction Markets
Trading prediction markets comes down to a few core mechanics: how contracts are priced, when to enter or exit, how settlement works, and what you’re paying in fees. Once those click, each market type is mostly a question of knowing what moves its prices and which source settles it.
Still, don’t mistake understanding the mechanics for having an edge. Most traders lose money, and thin liquidity can make even a well-reasoned position hard to exit. Start small, stick to markets you understand with real trading volume, and only risk money you’re prepared to lose. When you’re ready to pick a platform, our best prediction market apps guide and operator reviews can help you find the right fit.
Prediction Markets Trading Guide FAQ
Yes, it’s possible, but it’s not guaranteed. Most traders lose money, and every binary contract carries the risk of losing your full stake. Traders who profit consistently tend to specialize in a field they know well and manage risk carefully.
Sign up with a CFTC-regulated platform, fund your account, and pick a market you understand. Read the contract rules, choose Yes or No, place a market or limit order, then either sell before settlement or hold until the outcome is confirmed. Start with small amounts while you learn.
Yes. You can sell any time the market is open, whether to lock in a gain or cut a loss. Liquidity and your order type (market vs. limit) both affect the price you get.
Implied probability is the contract’s price read as a percentage. A 55¢ contract implies a 55 percent chance that the event happens.
They’ve held up well. A 2026 Federal Reserve working paper found Kalshi’s market-implied CPI forecasts had roughly 40 percent lower average error than consensus economist forecasts for headline inflation. Prices update continuously as new data arrives, so they often pick up shifts in expectations faster than monthly forecaster surveys.
Yes. Platforms like Kalshi list release-date markets for major AI models, with separate Yes/No contracts for different cutoff dates. These usually settle on the lab’s own announcement, so check the contract rules for the exact source and deadline.
Yes, but these are the most speculative AI contracts because there’s no universally accepted definition of AGI. Each contract’s rules decide what counts. Kalshi’s OpenAI AGI market, for example, resolves on OpenAI’s own announcement. Read the resolution source before trading, since “AGI” can mean different things on different platforms.
A market order executes instantly at the best available price. A limit order lets you set your own price and wait for another trader to match it.
Yes. Exchange or trading fees apply, and some platforms add technology or withdrawal fees. Structures vary by operator, so 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.
Sportsbooks set the odds and build in a house edge. Prediction markets let traders set prices peer-to-peer, and the platform charges fees instead. You can also sell your position at the current market price before the event ends, rather than relying on a sportsbook’s cash-out offer.
Prediction markets offered through CFTC-regulated exchanges are legal and available in most of the US. However, several states are challenging sports event contracts in court, and some restrict election markets, so availability can change. Check each platform’s eligibility rules for your state before trading.
The IRS hasn’t issued definitive guidance on prediction market winnings, so they may be treated as capital gains or ordinary income depending on the contract. Keep records of your trades and consult a tax professional.
Most platforms offer sports, politics, crypto, economics, pop culture, weather, mention, and AI or tech markets. Each uses the same Yes/No contracts, but coverage varies by platform.
