Build a Smart-Money Watchlist from Polymarket's Leaderboard

A watchlist is just the leaderboard with the wallet column kept. Thirdwatch's Polymarket Leaderboard Scraper returns Polymarket's ranked leaderboard as rows — PnL, volume, wallet, and identity fields — across daily, weekly, monthly, and all-time windows.

Skip the setup: Run this as a ready-to-go task on Apify — pre-loaded with the configuration from this guide.

Why build a smart-money watchlist

Smart-money tracking starts with a seed list — the wallets that consistently make money. The leaderboard provides the ranking and the proxyWallet provides the join key to on-chain tools.

Weekly PnL leaders with wallets gives you the watchlist to feed into further tracking.

The leaderboard's own data feed powers the scrape, so a window and a ranking metric in means the full ranked board out.

How does this compare to the alternatives?

Why this Actor

• Full ranked board as rows — not just the top of the page.
• Four windows: day, week, month, all.
• Rank by PNL or VOL with orderBy.
• Identity fields per trader: username, X handle, verified flag, proxy wallet.
• PnL and volume figures for the selected window on every row.

How to do it in 3 steps

Step 1: Configure the input

Set the inputs as shown below — timePeriod takes the targets, orderBy picks PNL or VOL ranking and limit bounds the board depth.

Step 2: Run the Actor

Run it from the console, the API, or the linked saved task. One dataset row is written per trader.

Step 3: Use the output

Each row carries rank, username, X handle, proxy-wallet address, verified flag, and the PnL and volume figures for the window.

{
  "timePeriod": "week",
  "orderBy": "PNL",
  "limit": 50
}

Each dataset row looks like:

{
  "rank": 1,
  "userName": "trader_pro",
  "xUsername": "traderpro",
  "proxyWallet": "0x1234...abcd",
  "pnlUsd": 842000,
  "volumeUsd": 12500000,
  "verified": true,
  "timePeriod": "month",
  "orderBy": "PNL"
}

What to watch for

PnL and volume are Polymarket's own leaderboard figures — point-in-time and window-scoped. Anonymous accounts return wallets without usernames.
