If you’ve heard people talking about “prediction markets” or seen Polymarket referenced in the news during elections, you’re not alone. Polymarket has grown into one of the most popular platforms for forecasting real-world events — from politics to crypto to sports.
This guide covers everything you need to know to understand Polymarket, how prediction markets work, and how to start using them.
What Is Polymarket?
Polymarket is a decentralized prediction market platform where users buy and sell shares in the outcome of real-world events. Instead of betting against a bookmaker, you trade shares with other users in an open market.
Each market on Polymarket asks a yes-or-no question. For example:
- “Will Bitcoin reach $150,000 by December 2026?”
- “Will the US enter a recession in 2026?”
- “Will SpaceX land on Mars before 2030?”
Users buy Yes or No shares. If you believe the answer is yes, you buy Yes shares. If you think it won’t happen, you buy No shares. When the event resolves, the winning shares pay out $1.00 each, and the losing shares are worth $0.
How Do Prediction Markets Work?
Prediction markets work like stock markets, but instead of trading company shares, you trade shares tied to the outcome of events.
The price is the probability
The current price of a Yes share represents the market’s estimated probability that the event will happen. If Yes shares are trading at $0.70, the market believes there’s roughly a 70% chance the event will occur.
This is what makes prediction markets so powerful — they aggregate the knowledge, opinions, and information of thousands of traders into a single probability number.
How trading works
- Find a market — browse by category (politics, crypto, sports, science, culture) or search for a specific topic
- Buy shares — if you think the event will happen, buy Yes shares. If you think it won’t, buy No shares
- Wait for resolution — when the event’s outcome is confirmed, the market resolves
- Get paid — winning shares pay $1.00 each. If you bought Yes shares at $0.30 and the outcome is Yes, you make $0.70 profit per share
You can also sell your shares at any time before the market resolves if you want to lock in a profit or cut a loss.
A quick example
Imagine a market: “Will it snow in New York City on Christmas Day 2026?”
- Yes shares are trading at $0.25 (the market says 25% chance)
- You check the weather forecast and see a major snowstorm predicted — you buy 100 Yes shares for $25
- It snows on Christmas — the market resolves Yes
- Your 100 shares are now worth $100 — you made $75 profit
If it doesn’t snow, your shares are worth $0 and you lose your $25.
Why Are Prediction Markets Accurate?
Prediction markets have a strong track record of being more accurate than polls, pundits, and expert panels. Here’s why:
- Skin in the game — traders risk real money, which forces careful analysis rather than wishful thinking
- Continuous updates — prices adjust in real time as new information becomes available
- Crowd wisdom — thousands of independent opinions are aggregated into a single price
- Arbitrage — if the market price is wrong, traders have a financial incentive to correct it
During the 2024 US presidential election, Polymarket’s odds were widely cited by major news outlets because they consistently reflected shifting public sentiment faster than traditional polls.
What Can You Trade on Polymarket?
Polymarket covers a wide range of categories:
- Politics — elections, policy decisions, legislation, government actions
- Crypto — Bitcoin price milestones, Ethereum upgrades, SEC rulings, DeFi events
- Sports — game outcomes, championships, player transfers
- Science & Technology — AI milestones, space exploration, FDA approvals
- Culture & Entertainment — award shows, viral moments, celebrity events

New markets are created regularly based on current events and community interest.
How to Get Started on Polymarket
Getting started takes just a few minutes:
- Visit polymarket.com or download their mobile app
- Connect a wallet — Polymarket runs on the Polygon blockchain, so you’ll need a crypto wallet (like MetaMask) or you can sign up with an email for a custodial wallet
- Deposit funds — fund your account with USDC (a stablecoin pegged to the US dollar)
- Browse markets — explore trending markets or search for topics you know well
- Place your first trade — buy Yes or No shares in any market
You don’t need deep crypto knowledge — Polymarket has simplified the onboarding for non-crypto users with email login and direct card deposits in some regions.
Key Concepts Every Beginner Should Know
Liquidity
Liquidity refers to how easy it is to buy and sell shares at fair prices. High-liquidity markets (like major elections) have tight spreads and large trading volumes. Low-liquidity markets may have wider spreads, meaning you might pay more to enter or exit a position.
Resolution
When the outcome of a market’s question is confirmed, the market resolves. Resolution is handled by Polymarket’s oracle system (powered by UMA’s optimistic oracle). If someone disputes a resolution, there’s a challenge period where the outcome can be reviewed.
Disputes
Sometimes a market’s initial resolution gets challenged. During a dispute, the outcome is reconsidered by token holders who vote on the correct result. Disputes can cause significant price swings, so it’s important to stay informed when markets you hold positions in enter this phase.
Fees
Polymarket charges minimal trading fees. The platform uses an order book model (not AMM), so you can place limit orders at your desired price. Gas fees on Polygon are extremely low — usually fractions of a cent.
Tips for New Polymarket Traders
If you’re just getting started, here are some practical tips:
- Start small — don’t risk more than you’re comfortable losing while you learn
- Stick to what you know — trade in categories where you have genuine knowledge or insight
- Watch the whales — large traders often have better information. When a whale makes a big move, pay attention
- Check resolution criteria — read the fine print. Some markets resolve on specific technicalities
- Diversify — don’t put everything into one market outcome
- Set alerts — use tools like Polymarket Alerts to get notified about price changes, whale trades, and market activity so you don’t have to check manually
How to Track Polymarket Activity in Real Time
One of the biggest challenges for active Polymarket traders is staying on top of fast-moving markets. Prices can shift dramatically when news breaks or a whale enters a position.
Polymarket Alerts is a free mobile app that sends you instant push notifications for:
- Price movements — set a target price or percentage change and get notified when it’s hit
- Whale trades — know immediately when someone makes a large trade in any market
- User activity — follow specific traders and see their moves in real time
- Insider trading patterns — the app flags suspicious trading activity that resembles insider knowledge
- Dispute alerts — get notified when a market enters a dispute phase

Frequently Asked Questions
Is Polymarket legal?
Polymarket operates as a decentralized platform. Regulatory status varies by jurisdiction. US users should be aware of evolving regulations around prediction markets. Polymarket reached a settlement with the CFTC in 2022 and has since restructured its operations. Always check your local laws.
Is Polymarket safe?
Polymarket runs on the Polygon blockchain with smart contracts that have been audited. Your funds are held in smart contracts, not in a centralized exchange. However, like any crypto platform, there are smart contract risks and market risks.
Can you make money on Polymarket?
Yes — if you correctly predict outcomes, you profit. Some traders consistently profit by specializing in areas they understand deeply. However, prediction markets are zero-sum: for every winner, there’s a loser. Don’t trade with money you can’t afford to lose.
How is Polymarket different from sports betting?
Traditional sportsbooks set odds and take the other side of your bet. On Polymarket, you trade directly with other users through an order book. This means prices are set by supply and demand, not by a bookmaker. Polymarket also covers a much wider range of events beyond sports.
Do I need crypto experience to use Polymarket?
Not anymore. Polymarket now offers email login with a built-in wallet, and supports card deposits in many regions. You don’t need to understand blockchain technology to place trades.

Prices reflect crowd-sourced probabilities, making prediction markets one of the most accurate forecasting tools available. Whether you’re interested in politics, crypto, sports, or science, Polymarket offers markets on virtually every major event.
