What Is a Prediction Market?
A prediction market is a platform where you can buy and sell contracts based on the outcomes of future events. Think of it like a stock market, but instead of trading company shares, you're trading on whether something will happen.
For example, you might trade on:
- Will a specific candidate win the presidential election?
- Will the Fed raise interest rates next month?
- Will a certain team win the Super Bowl?
- Will Bitcoin reach $100,000 by December?
Each contract typically pays out $1 if the event happens and $0 if it doesn't. The current price reflects the market's probability estimate.
How Do Prices Work?
Prediction market prices are elegantly simple: the price equals the probability.
If a contract is trading at 65 cents, the market believes there's a 65% chance that event will happen. If you think the true probability is higher, you buy. If you think it's lower, you sell (or buy the "No" contract).
If a "Yes" contract costs 30¢ and the event happens, you make 70¢ profit (receiving $1 payout). If it doesn't happen, you lose your 30¢.
This creates powerful incentives for accuracy. Traders who consistently estimate probabilities better than the market will profit over time.
Why Are Prediction Markets So Accurate?
Prediction markets have outperformed traditional polls and expert forecasts in many high-profile cases. Here's why:
1. Skin in the Game
When people trade with real money, they think carefully before acting. There's no room for wishful thinking or signaling—only your honest probability estimate matters.
2. Continuous Updates
Unlike polls that provide snapshots, prediction markets update in real-time as new information emerges. Prices immediately incorporate breaking news, insider knowledge, and shifting conditions.
3. Diverse Information Sources
Traders bring knowledge from many different domains. An economist might trade on Fed decisions, while a sports analyst focuses on game outcomes. The market aggregates all this distributed expertise.
4. Profit Motive Corrects Errors
If the market is wrong, there's money to be made by correcting it. This attracts sophisticated traders who push prices toward true probabilities.

Common Questions
Is this gambling?
Prediction markets are different from gambling in important ways. They're designed for forecasting and price discovery, not entertainment. Platforms like Kalshi are regulated as exchanges, not casinos. That said, you can still lose money, so only trade what you can afford to lose.
Are prediction markets legal?
In the US, Kalshi is the only fully legal and regulated option (CFTC-approved). Polymarket operates in a regulatory gray area for US users but is widely used internationally. Always check your local regulations.
How much money do I need to start?
You can start with as little as $10-20 on most platforms. Contracts typically cost between 5¢ and 95¢, so small amounts go a long way.
