How to track Polymarket wallets

Polymarket runs on Polygon, which means every trade ever made is public. You can follow any trader's every move — the only real questions are how to do it without living in browser tabs, and which wallets deserve the attention.

1

Find the wallet behind a trader

Every Polymarket profile URL contains the wallet: polymarket.com/profile/0x…. Click any name on a leaderboard or in a market's activity feed to get there. That address is the key to everything below.
2

Read their positions and history

The profile shows open positions, trade history, and PnL. For raw on-chain detail (transfers, timing, related wallets), paste the address into Polygonscan. Everything is public; no API key needed.
3

Judge whether the wallet is any good

This is where most people go wrong: raw profit means little. A wallet can bank millions risking $0.97 favorites or making markets — styles that say nothing about forecasting skill. Check return on money actually risked and whether the record holds across many resolved markets. Our skill ranking does this screen daily, or paste any address below.
4

Automate the watching

Manual tracking breaks down fast — big traders split one decision into hundreds of fills, and Polymarket has no follow alerts. A tracker does the sitting-and-watching for you: Shark Radar collapses fills into net position changes and sends one whale alert by email or Telegram when a watched trader makes a real move.

Common questions

Can you see other people's trades on Polymarket?

Yes. Polymarket settles on Polygon, so every trade, position, and PnL figure is public on-chain data. Any profile's full history is visible at polymarket.com/profile/<wallet address> — no login required.

How do I find a trader's wallet address?

Open their Polymarket profile — the wallet address is in the page URL (polymarket.com/profile/0x…). From a leaderboard or a market's activity feed, click the trader's name to reach that profile.

How do I get alerts when a whale trades?

Polymarket itself has no follow alerts — its notifications cover only price moves on your own positions. Third-party trackers fill the gap: Shark Radar sends a whale alert by email or Telegram when a tracked wallet's net position in a market changes materially, which filters out the hundreds of tiny fills big traders split their orders into.

Which wallets are worth tracking?

Not the raw-profit leaderboard — public backtests show past profit barely predicts future returns, and much whale PnL comes from uncopyable styles like market-making. Look for return on money actually risked, a record across many resolved markets, and skill that persists over time. That screening is exactly what Shark Radar's ranking automates.
