Getting Started with Polymarket: A Complete Beginner's Guide
Polymarket is the world's largest prediction market, allowing you to trade on the outcomes of real-world events. With over $9 billion in trading volume and an $8 billion valuation after their October 2025 ICE investment, Polymarket has become the gold standard for prediction markets.
What is Polymarket?
Polymarket is a cryptocurrency-based prediction market headquartered in Manhattan, New York City. Launched in 2020, it offers a platform where you can place bets on future events—from politics and economics to sports and entertainment.
Unlike traditional betting, prediction markets use the wisdom of crowds to generate probability estimates. If you think an event has a 70% chance of happening but the market shows 50%, you can buy "Yes" shares at a discount.
Setting Up Your Account
Getting started is simple:
- Visit Polymarket.com and click "Sign Up"
- Use your email address – they'll send you a "magic link" to instantly create your account and Polymarket wallet
- Connect your wallet (optional) – if you prefer using MetaMask or another Web3 wallet
That's it! No lengthy KYC process for international users (US users will need to use the regulated Polymarket US exchange launching in late 2025).
Depositing Funds
Polymarket uses USDC (USD Coin) on the Polygon network. Here are your deposit options:
Option 1: Polygon Network (Recommended)
- Click "Deposit" at the top of the page
- Select Exchange/Other > Polygon
- Copy your wallet address
- Send USDC from your exchange over the Polygon network
- Funds arrive in under a minute!
Option 2: Using Crypto.com (Cheapest)
Crypto.com charges only $0.08 flat fee to send USDC to Polymarket:
- Create a free Crypto.com account
- Buy or transfer USDC to Crypto.com
- Withdraw to your Polymarket address on Polygon
Option 3: Ethereum Network (MetaMask)
- Includes either a $3 or 0.3% fee (whichever is greater)
- Takes up to 30 minutes
- Better for larger deposits where the percentage fee is acceptable
Understanding the Interface
Market Cards
Each market shows:
- The question being asked
- Current odds (displayed as percentages or prices)
- Trading volume – higher volume means better liquidity
- Resolution date – when the market will settle
Buying Shares
- Yes shares pay $1 if the event happens
- No shares pay $1 if it doesn't happen
- Share prices reflect probability (e.g., 65¢ = 65% implied probability)
Example Trade
If "Will it rain tomorrow?" shows Yes at 40¢:
- Buy 100 Yes shares for $40
- If it rains: receive $100 (profit of $60)
- If no rain: lose your $40
Your First Trade
- Find a market you understand well
- Research the topic – don't just bet on gut feeling
- Start small – maybe $5-10 on your first trade
- Place your order – market orders execute instantly, limit orders wait for your price
- Monitor your position – you can sell before resolution to lock in profits or cut losses
Fees on Polymarket
Global Platform (International)
Polymarket charges zero trading fees. The platform doesn't take a cut of your trades. You only pay:- Gas fees on Polygon (typically fractions of a cent)
- The spread to liquidity providers (built into prices)
Polymarket US (Regulated Exchange)
Launching in late 2025 with just 0.01% fees (one basis point) – that's $0.01 on a $100 trade. This makes it over 100x cheaper than competitors like Kalshi.
Tips for Beginners
- Start with markets you understand – sports, elections you follow, events in your industry
- Check the resolution source – understand exactly how the market will be settled
- Mind the liquidity – thin markets can have wide spreads
- Don't bet your rent money – prediction markets are high risk
- Follow top traders – use tools like PolyTrack to see what successful traders are doing
