Polymarket Smart-Money & Whale Tracker

Polymarket Smart-Money & Whale Tracker is a Polymarket API for smart-money intelligence: track the most profitable Polymarket whale wallets, stream large prediction-market trades in real time, and score any trader's skill with a statistically-sound win rate — not a naive percentage. Use it for Polymarket copy trading research, whale alerts, quant backtesting, or as clean structured data for AI agents and LLM pipelines. Run it on demand or on a schedule and pull JSON straight from the Apify API.

What does Polymarket Smart-Money Tracker do?

It turns Polymarket's public on-chain activity into clean, structured data across three modes:

• Smart-money leaderboard — the top wallets ranked by all-time profit, each with trading volume and a capital-efficiency ratio (profit per dollar traded) so you can tell grinders from genuinely sharp traders.
• Whale trades feed — every recent trade above a USD threshold you set: who, which market, which side, how big, and when. This is your "smart money is moving right now" signal.
• Wallet analysis — a deep report on any wallet: open positions, realized and unrealized P&L, account age, top holdings, and a luck-resistant hit-rate confidence bound (95% Wilson lower bound — a lucky 4-for-4 wallet can't outrank a proven 180-for-300 one).

No login, no API keys, no browser automation — it reads Polymarket's own public data endpoints, so it's fast and reliable.

Why use Polymarket Smart-Money Tracker?

• Copy-trading research — find and vet wallets worth following before you mirror them.
• Alpha signals — detect large informed trades as they land.
• Backtesting & quant work — export skill-rated wallet lists and trade history as structured data.
• Market monitoring — watch where serious capital is concentrating.

Unlike the other whale trackers on the store, this one separates skill from luck: a wallet with 180 wins from 300 trades outranks one with 4 from 4, because the score is confidence-adjusted.

How to use Polymarket Smart-Money Tracker

1. Open the Actor and pick a Mode.
2. For the leaderboard, set how many wallets to return. For whale trades, set a minimum USD size. For wallet analysis, paste one or more wallet addresses.
3. Click Start.
4. Download the results as JSON, CSV, Excel, or HTML, or fetch them from the Apify API.

Input

Field	Mode	Description
mode	all	leaderboard, whale_trades, or wallet_analysis
leaderboardLimit	leaderboard	Number of top wallets to return (default 50)
minTradeUsd	whale_trades	Minimum trade notional in USD (default 1000)
tradesLimit	whale_trades	Max trades to return (default 100)
wallets	wallet_analysis	List of Polymarket proxy wallet addresses

Output

Wallet analysis returns rows like:

{
  "wallet": "0xf0318c32136c2db7fec88b84869aee6a1106c80c",
  "accountAgeDays": 175,
  "portfolioValueUsd": 730516.30,
  "openPositions": 2,
  "openInvestedUsd": 358247.00,
  "openUnrealizedPnlUsd": 305921.00,
  "realizedPnlUsd": 372920.84,
  "resolvedTrades": 257,
  "resolvedWins": 12,
  "resolvedLosses": 245,
  "hitRate": 0.0467,
  "hitRateLowerBound": 0.0269,
  "topHoldings": [
    {"market": "Will Spain win the 2026 FIFA World Cup?", "outcome": "Yes", "currentValueUsd": 601963.44, "cashPnlUsd": 305498.24}
  ]
}

That example is a real profitable whale: a low-hit-rate longshot trader. This is why we report hit rate and P&L separately instead of one misleading "score" — profitable prediction-market wallets are often right rarely but paid well when they are.

You can download the dataset in various formats such as JSON, HTML, CSV, or Excel.

Data fields

Field	Meaning
wallet	Polymarket proxy wallet address
pnlUsd	All-time profit (leaderboard mode)
volumeUsd	Total traded volume
capitalEfficiency	Profit divided by volume
hitRate / hitRateLowerBound	Share of resolved bets won, and its 95% Wilson lower bound (luck-resistant)
realizedPnlUsd / openUnrealizedPnlUsd	Settled vs live P&L, reported separately
portfolioValueUsd	Current value of open positions
usdValue	Notional size of a whale trade
market / outcome / side	What was traded

How much does it cost?

The Actor reads lightweight JSON endpoints, so runs are cheap and fast. You are charged per result returned (see the Pricing tab). A leaderboard of 50 wallets or a feed of 100 whale trades costs a fraction of a cent in most cases; wallet analysis costs a little more because it fetches positions and history per wallet.

Tips

• Schedule the whale trades mode every few minutes and connect it to Slack, Telegram, or a webhook via Apify Integrations to get live large-trade alerts.
• Feed the leaderboard into wallet analysis to rank top wallets by hit-rate confidence and realized P&L, not just headline profit.

FAQ and support

Is there an official Polymarket API for whale tracking? Polymarket exposes public data endpoints, but no ready-made smart-money layer. This Actor adds the intelligence: leaderboards, whale trade feeds, and skill-rated wallet analysis, delivered as JSON/CSV.

Can I use this for Polymarket copy trading? Yes — that's the core use case. Find consistently profitable wallets, check their hit-rate confidence bound and P&L decomposition, then monitor their new large trades with the whale feed.

Does it work for AI agents? Yes. Output is structured JSON designed for LLM tools, RAG pipelines, and agent frameworks. Schedule it and webhook the results anywhere.

How fresh is the data? Every run reads Polymarket's live public endpoints — no cached databases, no stale snapshots.

Is this legal? The Actor only reads Polymarket's public, no-auth data endpoints and does not collect private personal information. As always, review Polymarket's terms and your local rules before commercial use.

Why is hitRateLowerBound lower than hitRate? By design — it's a statistical lower bound, so it stays conservative until a wallet has a real track record.
