Polymarket beginner guide
New to prediction markets? This guide walks you through everything from wallet setup to your first trade — and how to find an edge once you're in.
1 — Understand prediction markets
Prediction markets let you trade on the outcome of real-world events. The price of each share reflects the market's belief in the probability of that outcome. A share priced at $0.70 means the market believes there's a 70% chance of the outcome happening — if it does, the share pays $1.00; if not, $0.00.

2 — Create your wallet
Mirrored runs entirely inside Telegram. There's no separate signup, no app to install, no MetaMask. The bot creates a non-custodial wallet for you the first time you message it.
- Open @mirrored_trade_bot in Telegram and send
/start. - The bot creates an embedded wallet via Turnkey — secured by your Telegram identity, not a seed phrase you have to copy down.
- You can export the seed any time from ⚙️ Settings → Security and take the wallet elsewhere. Mirrored never holds your funds.
3 — Fund your wallet
Polymarket trades are denominated in pUSD on Polygon. You've got a few options:
- Send pUSD on Polygon directly to your Mirrored wallet address.
- Bridge from another chain. The bot accepts USDC, USDT, ETH, SOL, and BTC from their respective networks; the bridge converts them to pUSD on Polygon automatically.
Mirrored doesn't process card payments. If you don't hold crypto yet, an exchange-to-self-wallet path (e.g. buy USDC on Coinbase, send to your Mirrored address) is the typical route.
Tip: start with $20–50 to get comfortable with the flow before scaling up. The minimum trade size is $1.10.
4 — Place your first trade (or skip straight to copying)
You've got two paths from here:
Trade manually
Browse Polymarket directly — the bot supports market discovery and order placement from chat. Pick an outcome (YES or NO), set your stake in pUSD, and confirm. Your position appears in your portfolio immediately.
Mirror traders
Most beginners do better by copying traders who already have a track record. Mirrored has two paths for this:
- AutoPilot — pick a curated lineup we maintain. The bot mirrors every entry from every trader in the lineup. No research required.
- Manual copy trading — paste any Polymarket wallet address and the bot starts mirroring. Use the Mirrored leaderboard to find profitable wallets.
Either way, you'll set sizing rules once: how much per trade, max per market, price band, and slippage tolerance. The full breakdown is in how to copy trade on Polymarket.
5 — Follow data, not opinions
The difference between beginner and profitable traders is simple: profitable traders rely on data, not gut feel. The Mirrored leaderboard ranks Polymarket wallets by 30-day realized PnL, win rate, and risk-adjusted consistency — pick from the top before you pick from your gut.
Common beginner mistakes
- Betting your whole balance on one market. Diversify across markets and across traders. Even strong wallets have losing streaks.
- Ignoring liquidity. Low-volume markets have wide spreads — you can buy fine but struggle to exit. Stick to markets with healthy depth.
- Trading on emotion. A price drop doesn't always mean "sell." Revisit the data first.
- Skipping the resolution rules. Read the market description carefully. Some have nuanced criteria that aren't obvious from the title.
- Buying at
$0.90+. Markets priced above 90¢ have limited upside; the risk-reward is poor unless you have very high conviction.
