How PolymarketTrade Works
Trade prediction markets in 4 simple steps. No accounts, no KYC — just your wallet.
- 1
Connect your wallet
Self-custody from the first click. We never see your private keys.
- Click Connect Wallet in the top-right.
- Pick your wallet: MetaMask, Phantom, Coinbase Wallet, or any EIP-6963 wallet (Rabby, Rainbow, OKX, Brave, Frame…).
- Approve the connection in the wallet popup.
- Make sure you're on the Polygon network — the app prompts you to switch automatically.
- 2
Get pUSD (the trading collateral)
Polymarket markets settle in pUSD, a 1:1 USD-pegged token on Polygon.
- Don't have pUSD yet? Use relay.link to swap any token (ETH, USDC, USDT, SOL, BNB…) into pUSD on Polygon.
- Send pUSD to the wallet you connected.
- Already hold USDC.e on Polygon? You don't need to swap — the app auto-wraps USDC.e into pUSD on your first order (one extra signature, no extra fees).
Tip: keep a tiny amount of POL (Polygon's native token) in the wallet for gas — usually under $0.50 covers a full week of trading.
- 3
Pick a market
Every market is a Yes/No question that resolves on a known date.
- Browse by category in the left sidebar: Politics, Crypto, Sports, Macro, AI, Fed, Equities, Weather, Culture…
- Use the search bar in the header to jump straight to a market by name.
- Click any market card to open its trading panel.
- Read the question and the resolution rules — prices are probabilities (60¢ ≈ 60% chance).
- 4
Place an order
Two order types — pick the one that matches the moment.
Market orderInstant execution at the current price.- Click YES (it will happen) or NO (it won't).
- Type the amount in pUSD you want to spend.
- Click Place Buy Order.
- Sign once in your wallet — the order fills immediately.
Use when: news is moving and you want in now.
Limit orderYou set the price — the order waits for a match.- Switch the order type from Market to Limit.
- Set your price (e.g.
35¢) and your size. - Click Place Limit Order and sign.
- The order rests on the book — it can fill in full, in parts, or wait.
Use when: you want a better price and you're not in a hurry.
Cancel an open order
- Open My Activity (top-right or below the header on mobile).
- Find the order under Open Orders.
- Click Cancel — or Cancel rest if it's already partially filled.
- Cancellation is gas-free and instant.
Winning and losing scenarios
Each share pays exactly $1 if it wins and $0 if it loses. Profit and loss are simple math.
- You bought 100 YES shares at 30¢ = $30 spent.
- Market resolves YES.
- You receive $100 (100 × $1).
- Net profit: +$70.
- Click Redeem in My Activity to claim your pUSD.
- You bought 100 YES shares at 30¢ = $30 spent.
- Market resolves NO.
- Each YES share is now worth $0.
- Net loss: −$30 (the amount you spent — never more).
- No redemption needed; the position closes automatically.
You can also sell early any time before the market resolves — close a winning position to lock in gains, or cut a losing one short. Use the same trading panel, switch the side to SELL.
Quick tips
- Prices reflect probability:
67¢means ~67% chance per the order book. - Buy low, sell high — you don't have to wait for resolution.
- Limit orders earn you the spread; market orders cost it.
- Keep your wallet on Polygon. Mainnet ≠ Polygon.
- Position too small to redeem? Most wallets show $0.01–$0.99 redemptions correctly — check My Activity.
