Polymarket Top Traders — Leaderboard + Verified P&L Profiles

The Polymarket trader leaderboard (by P&L or volume, per category, per time window) — plus what raw leaderboards never tell you: is this trader actually worth following? Enriched mode adds each trader's live open positions, verified open P&L, cross-window consistency, and recent activity stats, straight from Polymarket's public APIs. Built for copy-trading research, smart-money tracking, and prediction-market analytics.

Why this one

• Leaderboards lie by omission. A trader can top the DAY board with one lucky longshot. We check every top trader against all four windows (DAY / WEEK / MONTH / ALL) and report how many they rank in — one-hit wonders are obvious at a glance.
• Verified open P&L, not just the headline number. For each enriched trader you get their current positions, portfolio value, and open P&L computed from the live positions API — every number traceable, nothing modeled.
• Copy-trading signals included: tradesLast7d, avgTradeUsd7d, activeLast7d, lastActivityAt — know whether the trader is still active before you follow them.
• Partial-failure resilient. One bad wallet never kills your run.
• No API keys, no wallet, no login — public Polymarket endpoints only.

Modes

Mode	What you get	Typical use

profiles	The same rich profile for explicit wallet addresses	Track specific traders over time

Categories & windows

All 10 Polymarket categories (OVERALL, POLITICS, SPORTS, CRYPTO, CULTURE, MENTIONS, WEATHER, ECONOMICS, TECH, FINANCE) × 4 time windows (DAY, WEEK, MONTH, ALL), ranked by PNL or VOL.

Quick start

1. Run with defaults — top 25 OVERALL weekly P&L leaders.
2. Switch to enriched mode to vet the top 10 before following anyone.
3. Schedule it daily and diff the results to catch new names entering the boards.
4. Pipe into the Polymarket Whale Tracker actor (same author) to watch the wallets you picked in real time.

Pricing

Pay-per-event: cheap leaderboard-row events for raw rows; trader-profile events only for the rich enriched/profile records you actually receive.

Use with AI agents (Claude, Cursor, n8n — MCP)

This Actor works out of the box as an MCP tool. Point your agent at Apify's hosted MCP server and it can call the Actor directly:

{
  "mcpServers": {
    "apify": {
      "url": "https://mcp.apify.com?tools=mrlarryjohnson/polymarket-top-traders"
    }
  }
}

OAuth sign-in happens on first connect (or use an Authorization: Bearer <APIFY_TOKEN> header). Your agent can then fetch trader leaderboards and verified P&L profiles on demand and reason over the results — same pay-per-event pricing, no extra setup.
