| Polymarket | `~20 min` (wallet setup) |
| **Opinion** | **`~5 min`** (email + card) |
Opinion's web2-style onboarding lets a first-time prediction-market user place a trade in roughly the time it takes to make a coffee.

## Quick Answer
A prediction market is a place where you can buy and sell contracts on real-world outcomes β sports results, elections, macroeconomic events β and the price of each contract is, effectively, the probability the market assigns to that outcome. This guide walks a complete beginner from "I have no idea what this is" to "I'm comfortable placing my first contract" in about 15 minutes of reading.
If you prefer video, the embed above is a 1-minute primer; the article below is the thorough written walkthrough.
## What is a Prediction Market?
A prediction market is a marketplace where contracts pay out based on whether a real-world event happens.
The simplest example: a contract pays **\$1.00 if Brazil wins the 2026 World Cup**, and **\$0.00 if they don't**.
If the market currently prices that contract at **\$0.18**, it's saying: "We think Brazil has roughly an 18% chance of winning."
You can:
* **Buy** the contract β paying \$0.18 to potentially receive \$1.00.
* **Sell** if you already hold one β taking the current price as cash.
That's it. Everything else is variations on this basic mechanic.
***
## How Prices Become Probabilities
The link between price and probability is the most important concept to grasp.
A contract that pays \$1 if an event happens, and \$0 if it doesn't, has an "expected value" equal to the probability of the event. If a fair-coin flip pays \$1 on heads, \$0 on tails, the fair price is \$0.50 β 50%.
So when you see a price on a prediction market, just multiply by 100 and read it as a percentage:
| Price | Implied Probability |
| ------ | ---------------------------------- |
| \$0.05 | 5% |
| \$0.18 | 18% |
| \$0.50 | Coin flip β 50% |
| \$0.72 | 72% |
| \$0.95 | 95% (the market is very confident) |
You don't have to wait until the event resolves to take action. You can sell your contract at the current market price whenever you want.

## Why People Trade Them
Three motivations cover most users:
1. **Information.** Prediction markets aggregate the beliefs of many participants into a single number. A lot of people read prediction-market prices the way they'd read a poll average β as a signal of consensus.
2. **Hedging.** If you have real-world exposure to an outcome (you run a company that depends on Brazil winning a contract; you're a fan emotionally invested in a team), you can buy contracts that pay if the bad outcome happens β and offset the pain.
3. **Trading.** If you think the market price is wrong, you can buy or sell to profit from the disagreement.
The third use case is what brings most new users in.

## Your First Trade β Step by Step
We'll use Opinion in this walkthrough because the onboarding is the simplest. The conceptual steps apply to all platforms.
### Step 1 β Sign up
1. Go to [app.opinion.trade](https://app.opinion.trade).
2. Sign up with email, Google, or by connecting a wallet. The flow is similar to opening a Robinhood or Coinbase account.
3. Complete any required verification.
### Step 2 β Browse markets
The home page shows categories: politics, sports, crypto, esports, etc. Click "Sports" (or "FIFA 2026" once we're closer to the tournament) to see the catalog.
### Step 3 β Pick a market
Click into a specific market, for example "Will Brazil win the 2026 FIFA World Cup?" You'll see:
* The current price (probability)
* The price chart (how the probability has moved over time)
* Order book or liquidity indicator
* Your potential payout
### Step 4 β Decide YES or NO
* If you think the probability is **higher than the market's current price** β buy YES.
* If you think it's **lower** β buy NO (or sell YES if there's a NO contract on this market).
Don't overthink the first trade. Use a small amount β \$5 or \$10 β to learn the interface.
### Step 5 β Enter your stake
Type the amount. The interface shows your projected payout if you're right, and what you lose if you're wrong.
### Step 6 β Confirm
Click confirm. Your position is now live in your portfolio. You'll see it mark-to-market β the value updates as the market price moves.
### Step 7 β Decide when to close
You don't have to wait until the event resolves. You can sell your position at the current market price any time before resolution.

## What Beginners Get Wrong
A few classic mistakes:
1. **Treating it like a coin flip.** Prediction markets are not a 50/50 coin flip. The price is the probability. Buying a contract at \$0.90 is a low-return, low-risk position; buying at \$0.10 is a high-return, high-risk position.
2. **Putting in too much on the first trade.** Use \$5 or \$10 until you understand the interface, fees, and how it feels to hold a position.
3. **Not reading the resolution criteria.** "Will the team win" might exclude draws or penalty shootouts depending on how the market is worded. Always read the small print.
4. **Forgetting about fees.** They look small but compound. See [Cheapest Prediction Markets by Fees](/learn/prediction-markets-lowest-fees-comparison).
5. **Trading on emotion.** If you're a Brazil fan, you'll have a hard time pricing Brazil markets neutrally. Notice the bias.

## Prediction Markets vs Sportsbooks
If you've used a sportsbook (DraftKings, FanDuel, Bet365), this section is for you.
The biggest difference: on a sportsbook, you bet against the **house**. The house sets a line and bakes in a margin (called "vig" or "overround", usually 5β8%). On a prediction market, you trade against **other users**, with the platform taking a much smaller cut (typically 1β3%).
This means:
* **Lower take rate** β over many trades, your break-even is closer to 50/50 rather than 53%.
* **No bonuses to chase.** Sportsbooks compete on signup promos; prediction markets compete on fees.
* **You can sell your position before resolution.** Sportsbooks call this "cash out" and offer it on some bets; prediction markets offer it on every contract.
* **Live markets, not one-time picks.** You can see the price move in real time and trade based on it.

## A Vocabulary Cheat Sheet
| Term | What it means |
| ----------------------- | ----------------------------------------------------------------------------- |
| **YES / NO** | The two sides of a binary contract. YES pays \$1 if the event happens. |
| **Resolution** | When the event happens and contracts pay out. |
| **Liquidity** | How easy it is to buy/sell at a fair price. High liquidity = tight spread. |
| **Spread** | The gap between the highest buy price and the lowest sell price. |
| **Mark-to-market** | The current value of your position based on the latest price. |
| **Implied probability** | Price Γ 100. The market's estimate of how likely the event is. |
| **Order book** | The list of standing buy and sell offers on a market. |
| **Oracle** | The mechanism that decides how a contract resolves (in crypto-based markets). |

## Where Opinion Fits
For beginners specifically, **Opinion** is built to make the first 30 minutes feel like opening a sportsbook or a stock app rather than learning a crypto wallet. The deepest beginner path is around **sports** β events you already understand β rather than abstract macro or political markets.
Start at [`https://app.opinion.trade/world-cup`](https://app.opinion.trade/world-cup) if you want a guided first trade on a tournament market. Educational only β not investment or gambling advice; availability and product rules vary by jurisdiction.
## What to Watch
After you read this guide, the single most useful exercise is to place your first small contract and watch what happens. Track:
* **Did the price move after you bought?** That's how you learn whether your read was already in the market.
* **How does the order book change?** When new participants arrive, the depth at each price changes β you'll see this in real time.
* **What is the spread at the size you actually want to trade?** Top-of-book size often misrepresents what's available.
* **Resolution timing.** When the event resolves, how quickly does the market pay out, and does the price converge to 0 or 1 cleanly?
## FAQ
A marketplace where you can buy contracts that pay out if a real-world event happens. The contract's price represents the probability the market is assigning to that event.
There's overlap but also a real difference: gambling typically pays the house; prediction markets connect users with users and take a small fee. The information value is also different β prediction-market prices are often cited by journalists and analysts as a probability indicator.
**Opinion** for ease of onboarding (signup feels like a trading app). **Manifold Markets** if you want to learn with play money first.
\$5 or \$10 is enough to learn the interface. There's no high minimum.
Major platforms have years of operating history and run transparent settlement. The risks are: losing your stake if you're wrong, the platform pausing or shutting markets in certain jurisdictions, and (on crypto platforms) wallet security. Use platforms you've researched and don't deposit more than you can afford to lock up.
Yes, particularly on platforms like Opinion that have sports-focused catalogs. For the 2026 FIFA World Cup, prediction markets offer tournament winner, group advancement, top scorer, and per-match markets.
Stocks pay dividends and have indefinite life. Prediction-market contracts resolve at a specific event and pay \$0 or \$1 (in most designs). The mental model is otherwise similar β you're trading on probability rather than on company performance.
