What Is Polymarket? Complete Guide to Prediction Markets in 2026
Polymarket is the world's largest prediction market, where you buy and sell shares on real-world events — elections, crypto prices, geopolitics, sports, and more. This guide covers everything: how it works, how to start trading, legal status across countries, and tips for beginners.

What Is Polymarket?
Polymarket is a decentralized prediction market platform built on the Polygon blockchain (an Ethereum Layer 2 network). Founded in 2020 by Shayne Coplan, it allows anyone to buy and sell shares representing the outcome of real-world events.
Think of it as a stock market, but instead of trading company shares, you trade shares in the outcomes of questions like “Will the Fed cut interest rates in June 2026?” or “Will Bitcoin exceed $200,000 by December?” Each share is priced between $0.01 and $1.00, where the price represents the market's implied probability of the event occurring.
Polymarket gained massive attention during the 2024 U.S. presidential election, where it processed over $3.5 billion in trading volume and correctly predicted the outcome more accurately than traditional polls. Since then, it has expanded into thousands of active markets covering politics, economics, crypto, technology, entertainment, science, and sports.

How Prediction Markets Work
Prediction markets work on a simple principle: the price of a share equals the market's consensus probability of an event happening. This mechanism is called “price discovery” and it aggregates information from thousands of participants, each with their own knowledge and analysis.
Binary Markets (Yes/No)
Most Polymarket markets are binary — they resolve to either “Yes” or “No.” You can buy shares in either outcome.
Example: “Will Bitcoin hit $200K in 2026?”
- “Yes” shares trading at $0.35 = market thinks 35% probability
- “No” shares trading at $0.65 = market thinks 65% probability
- Note: Yes + No always = $1.00
If you believe Bitcoin will hit $200K and you're right, you bought at $0.35 and get paid $1.00 — a 186% return. If you're wrong, you lose your $0.35.
Multi-Outcome Markets
Some markets have multiple possible outcomes — for example, “Who will win the 2026 Canadian federal election?” might have shares for Poilievre, Carney, Singh, and others. Each outcome has its own price, and all prices sum to approximately $1.00.
Trading Before Resolution
You don't have to hold until the event resolves. Like stocks, you can sell your shares at any time at the current market price. If you buy “Yes” at $0.30 and the probability rises to $0.60 based on new information, you can sell for a 100% profit without waiting for the event.
Resolution & Settlement
When an event occurs, the market resolves. Winning shares are worth $1.00 and losing shares are worth $0.00. Resolution is handled by a decentralized oracle system (UMA protocol) that verifies real-world outcomes on-chain. Payouts are automatic — your USDC is returned to your wallet.
How to Create an Account & Start Trading
Getting started on Polymarket takes about 10-15 minutes. Here's a step-by-step walkthrough:
Sign Up
Visit polymarket.com and click “Sign Up.” You can register with an email address (Polymarket creates a wallet for you automatically) or connect an existing crypto wallet like MetaMask, Coinbase Wallet, or Rabby.
Complete Identity Verification (KYC)
Polymarket requires identity verification for all users. You'll need a government-issued photo ID (passport, driver's license, or national ID) and a selfie. Verification typically takes 5 minutes to 24 hours. You cannot trade without completing KYC.
Deposit USDC
Polymarket exclusively uses USDC on Polygon. You can:
- a) Deposit USDC directly from any wallet/exchange that supports Polygon
- b) Use Polymarket's built-in deposit flow via card payment (availability varies by country)
- c) Bridge USDC from Ethereum mainnet to Polygon using the Polygon Bridge
Tip: Always send USDC on the Polygon network, not Ethereum. Polygon fees are fractions of a cent, while Ethereum gas can cost $5-20+.

Browse markets by category or search for specific topics. When you find a market you have an opinion on, click it to see the order book. Choose “Yes” or “No,” set your amount, and confirm. Your shares appear in your portfolio immediately.
Types of Markets on Polymarket
Polymarket hosts thousands of active markets across a wide range of categories. Here are the major ones:

The biggest category by volume. U.S. presidential and congressional races, Canadian federal elections, European Parliament, Latin American elections, approval ratings, and policy outcomes. Polymarket often beats polls in accuracy.
Crypto & Finance
Bitcoin price milestones, ETH/BTC ratio, DeFi protocol events, Fed interest rate decisions, inflation data, stock market milestones, and crypto regulation outcomes.
Sports
Major championships, MVP awards, transfer rumors, and season outcomes. Soccer, basketball, American football, MMA, tennis, and more. Typically shorter resolution times.
Geopolitics & World Events
Conflicts, trade agreements, sanctions, UN resolutions, climate targets, and diplomatic outcomes. These markets attract informed participants with deep domain knowledge.

Entertainment & Culture
Award show outcomes (Oscars, Grammys), box office milestones, viral events, celebrity news, and pop culture predictions. Fun markets for casual traders.
Is Polymarket Legal?
The legality of Polymarket depends on where you live. Prediction markets exist in a regulatory gray area in many jurisdictions — they're not quite gambling, not quite financial trading. Here's the current status in major regions:
United States
Polymarket is CFTC-regulated but U.S. residents have limited access. After a $1.4 million settlement with the CFTC in 2022, Polymarket restructured to offer U.S. users access only to certain CFTC-approved event contracts. U.S. users can trade on some election markets but not all market types. Full access requires being outside the U.S.
Is Polymarket Legal in Canada?
Yes, Canadians can use Polymarket. Canada does not have specific legislation prohibiting prediction markets. The platform is not blocked for Canadian users, and there is no equivalent of a CFTC ban. Canadian securities regulators (CSA) have not issued guidance specifically targeting prediction markets.
However, the regulatory landscape is evolving. Canadian users should be aware that:
- - Profits from Polymarket may be taxable as capital gains or income (consult a tax professional)
- - Provincial gambling regulators have not classified prediction markets
- - Full KYC is required — Canadian passports and driver's licenses are accepted
- - Canadian exchanges like Shakepay, Newton, or Bitbuy can be used to purchase USDC
With the 2025 Canadian federal election drawing massive interest on Polymarket, Canadian participation has surged significantly.
European Union
Polymarket is accessible in most EU countries. The MiCA (Markets in Crypto-Assets) regulation that took effect in 2024 primarily targets crypto asset service providers, not prediction market users. However, individual countries may introduce restrictions. France's AMF and Germany's BaFin have not specifically addressed Polymarket.
United Kingdom
The UK Gambling Commission has not explicitly regulated prediction markets. Polymarket is accessible from the UK, but the regulatory status is ambiguous. The FCA may consider some event contracts as financial instruments, which would require authorization.
Rest of World
Polymarket is accessible in most countries. Known blocked regions include sanctioned territories and a handful of countries with strict gambling or crypto bans. Argentina, Brazil, India, Australia, Japan, South Korea, and most of Southeast Asia have access.
Disclaimer: Regulatory status changes frequently. This information is current as of March 2026 but may not reflect the latest developments. Always verify the legal status in your specific jurisdiction before trading.
Polymarket vs Gambling & Sports Betting
A common question: is Polymarket just gambling with extra steps? The answer is nuanced. Here's how prediction markets fundamentally differ from traditional gambling and sports betting:
| Aspect | Polymarket | Casino / Sportsbook |
|---|---|---|
| House edge | None (peer-to-peer) | 1-15% depending on game |
| Who sets odds | The market (all participants) | The bookmaker/casino |
| Skill factor | High (research & analysis) | Low to medium |
| Can you exit early? | Yes (sell shares anytime) | Limited (cash out on some) |
| Long-term expected value | Positive (if skilled) | Negative (house always wins) |
| Result timing | Days to months | Seconds to hours |
| Entertainment value | Low (data-driven) | High (visual, social) |
The critical difference is that on Polymarket, there is no house edge. You're not playing against a casino that mathematically wins over time — you're trading against other humans. If you have better information, analysis, or judgment, you can consistently profit. This makes Polymarket closer to financial trading than gambling.
That said, prediction markets carry real financial risk. You can lose your entire position if your prediction is wrong. And like any market, there's a risk of low liquidity, manipulation, or resolution disputes. Treat it as informed speculation, not a guaranteed income stream.

Fees, Risks & Tips for Beginners
Fees
- Trading fees: Polymarket charges no explicit trading fees. However, you pay the bid-ask spread (~1-3% on liquid markets, potentially more on illiquid ones).
- Deposit fees: No fees from Polymarket. You only pay blockchain gas fees (near-zero on Polygon).
- Withdrawal fees: No platform fees. Only Polygon gas (~$0.01).
- Hidden costs: Slippage on large orders; opportunity cost of capital locked in long-running markets.
Risks
Total Loss of Position
If your prediction is wrong, your shares go to $0. You lose 100% of what you invested in that market. Never invest money you can't afford to lose.
Liquidity Risk
Some markets have thin order books. You may not be able to exit a position quickly or at a fair price, especially in niche or low-volume markets.
Resolution Disputes
Occasionally, market resolution is contested. The UMA oracle system resolves disputes, but this can take time and the outcome may not match your expectation of what “correct” means.
Smart Contract Risk
As a blockchain-based platform, there is always a theoretical risk of smart contract bugs. Polymarket has been audited, but no system is 100% immune to technical failures.
Regulatory Risk
Governments may restrict or ban prediction markets at any time. If your country blocks Polymarket, you may face difficulties accessing or withdrawing funds.
Tips for Beginners
1. Start Small
Begin with $20-50 to learn the platform mechanics. Make small trades across several markets to understand how pricing, liquidity, and resolution work.
2. Trade What You Know
Your edge comes from knowing more than the market consensus. If you follow Canadian politics closely, trade Canadian election markets. If you understand crypto, trade Bitcoin price markets. Don't trade markets where you have no informational advantage.
3. Calculate Expected Value
Before every trade, ask: “Do I believe the true probability is higher than what the market price implies?” Use our EV Calculator to quantify whether a position has positive expected value.
4. Diversify Across Markets
Don't put all your capital in one market. Spread your positions across different categories and time horizons to manage risk.
5. Understand Resolution Rules
Read each market's resolution criteria carefully before trading. “Will X happen by December 31?” means exactly that — not December 30, not “approximately.” Ambiguous resolution criteria are the most common source of disputes.
Advanced Strategies
Once you're comfortable with the basics, these strategies can improve your results:
Arbitrage
Sometimes, related markets are mispriced relative to each other. For example, if “Party A wins the election” is priced at $0.40 but “Party A's leader becomes PM” is priced at $0.50, there may be an arbitrage opportunity. This requires monitoring multiple markets simultaneously.
Event-Driven Trading
Position yourself before major catalysts — debate nights, economic data releases, court rulings, or earnings announcements. Markets often move sharply when new information drops. If you can anticipate the direction, you can enter at favorable prices.
Selling Overvalued “No”
Many beginners only think about buying “Yes” on events they believe will happen. But buying “No” on events you believe are overpriced can be just as profitable — and often less competitive because fewer traders think this way.
Portfolio Hedging
Use prediction markets to hedge real-world exposure. If you hold Bitcoin and worry about a crash, buying “No” on a Bitcoin price market creates a partial hedge. This is a sophisticated use of prediction markets that bridges trading and risk management.
Frequently Asked Questions
Is Polymarket safe?
Polymarket is one of the most established prediction market platforms with billions in volume and CFTC oversight. It operates on audited smart contracts. However, no platform is risk-free. Use only funds you can afford to lose and keep large holdings in your own wallet.
What is the minimum deposit?
There is no official minimum deposit. However, since Polymarket runs on USDC, practical minimums are around $5-10 to cover at least a few meaningful trades. Polygon gas fees are negligible (~$0.01).
Can I lose more than I invest?
No. Your maximum loss on any market is the amount you paid for your shares. There is no margin trading, no leverage, and no possibility of negative balance. If you buy $50 worth of shares and your prediction is wrong, you lose exactly $50.
How is Polymarket different from Kalshi?
Both are prediction markets, but Kalshi is fully U.S.-regulated (CFTC-designated DCM), requires USD deposits (not crypto), and has a more limited selection of markets. Polymarket is crypto-native, runs on Polygon, uses USDC, and has a broader global market selection. Kalshi is more accessible for U.S. users who prefer traditional banking.
Do I have to pay taxes on Polymarket profits?
In most jurisdictions, yes. Polymarket profits are generally treated as taxable income or capital gains. In the U.S., Canada, EU, and UK, you should report prediction market earnings. Tax treatment varies by country — consult a tax professional familiar with crypto and prediction markets.
Can I create my own market on Polymarket?
Currently, market creation is managed by the Polymarket team. You can suggest markets through their Discord or social channels, but you cannot permissionlessly create a market like on some DeFi protocols.
Is Polymarket legal in Canada?
Yes. Canada has no specific prohibition on prediction markets. Polymarket is fully accessible for Canadian residents with a valid Canadian ID for KYC. Read the legal status section above for more details on Canadian access.
What happens if Polymarket shuts down?
Your funds are held in smart contracts on the Polygon blockchain, not in Polymarket's bank account. In theory, even if the frontend goes down, the smart contracts would still function. However, market resolution would depend on oracle availability. It's good practice not to keep excessively large amounts on any single platform.
