How to look up a Polymarket wallet
Polymarket settles trades on the Polygon blockchain, so every account's positions and trades are public. Each account trades from its own wallet address, which is what the tracker reads.
If you sign in to Polymarket with MetaMask or another wallet app, that wallet is not the one holding your positions: Polymarket gives each account a separate trading wallet (Polymarket's wallet types). Look up the address on your Polymarket profile, not the one in your wallet app.
- Copy the trader's wallet address (it starts with 0x), type their @username, or paste the link to their polymarket.com profile.
- Press Look up. A wallet CoinStats already tracks answers at once. A new one shows its first numbers within a few seconds, then fills in win rate and history, usually within a minute.
- Read the totals, then the open positions and latest trades. Each market links to its odds page on this site.
- Share what you found: the page's address now ends in ?wallet= and opens the same wallet for anyone.
Whale tracker or wallet tracker?
A wallet tracker starts from one wallet you already know about: a trader you saw on X, a friend, your own account. A whale tracker starts from the money: which wallets are the biggest and most profitable, and what they hold.
This page does both. The table is the whale view: Polymarket's own profit leaderboard, with whales and smart money marked. The search box is the wallet view. To see where those wallets are positioned market by market, use smart money signals.
Who counts as a whale or smart money
CoinStats sets both flags from each wallet's Polymarket history. The rules below are the ones the flags run on, as the CoinStats API states them. The trade count in the smart-money rule is CoinStats' own, which can differ from the lifetime trades a lookup shows, so a wallet that looks like it meets the rule may carry no flag.
- Whale
- Lifetime traded volume of at least 100,000 (Polymarket's "Total Volume"), or at least 3 trades of $10,000 or more in the last 7 days. Re-evaluated hourly.
- Smart money
- In profit overall, a win rate of at least 55%, at least 20 trades and 10,000 of lifetime volume, and a smart-money score of at least 200: win rate × 2 + log10(PnL + 1) × 20 + log10(volume + 1) × 10 + trades × 0.5. Re-evaluated every 2 hours.
The flags cover the wallets CoinStats syncs: Polymarket's 300 most profitable traders, re-read about every six hours, and any wallet looked up here. A profitable wallet outside both sets carries no flag until someone looks it up.
What to check besides PnL
Sample size. A 90% win rate over 10 resolved positions says little; over 1,000 it says a lot. The lookup shows how many resolved positions the win rate counts.
Total PnL against the leaderboard figure. The all-time leaderboard ranks by realised profit after trading fees; Total PnL is before fees and includes open positions at today's prices. The gap is the fees paid plus whatever rides on unresolved positions, and on many top wallets it is all fees: @swisstony's $5.1M gap has no open positions behind it.
Trade count. A wallet with hundreds of thousands of trades is usually automated, often a market maker earning a little on a lot of volume. Its profit says little about picking outcomes.
Profit per dollar traded. A few thousand dollars of profit on millions of volume is market making, not forecasting.
Recent form. The 7-day and 30-day PnL and the 30-day line show whether a record is current or years old.
Copy trading Polymarket wallets: why to be careful
Copying a profitable wallet looks like a shortcut. It rarely does as well as the wallet's own record, for four reasons.
You buy later, at a worse price. By the time a trade shows up and you copy it, the price has often moved, and on a thin market your own order moves it further.
You see entries, not the plan. A wallet may hedge in another market, sell over several days or hold to resolution; one copied trade misses the rest.
The best records include luck. Among millions of wallets, some winning streaks are chance. A long record across many markets is a better guide than one big win.
Market makers don't predict. Their profit comes from spreads and rebates across thousands of trades, which a copy can't reproduce.
Can you track Polymarket US or Kalshi traders?
No. Polymarket US is a separate, CFTC-regulated exchange: its accounts are identity-verified and not on-chain, so they can't be tracked. This tracker covers wallets on Polymarket's international exchange, polymarket.com.
Kalshi is a centralised, CFTC-regulated exchange too. Its accounts aren't on a blockchain, and it doesn't publish which account made which trade, so there is no wallet to look up.
