Every large bet on Polymarket, across every market, the moment it happens, and who placed it. Each bet carries the bettor's rank and profit on Polymarket's own leaderboard, all time and over the last 30 days, so a top-50 trader putting $40K on an outcome stands out from someone down $300K doing the same.
Put it on a schedule (every 5 to 15 minutes) and each run returns only the bets placed since the last one. Connect it to Slack, Telegram, email or a webhook through Apify integrations for whale alerts.
No key, no login, no browser, no proxy: it reads Polymarket's public data API.

Examples
- Whale alerts: defaults, scheduled every 10 minutes
- Only proven traders:
onlySmartMoney: true - Stricter smart money:
smartMoneyTopRank: 50 - Only one topic:
marketKeywords: ["election"]or["bitcoin", "ethereum"]or["fed", "rate"] - Follow specific wallets (copy-trading research):
wallets: ["0x..."],minBetUsd: 100 - What happened today:
onlyNew: false,lookbackMinutes: 1440
How it works
- Reads every Polymarket trade since the last run above a tenth of your minimum, because a big order can fill as several smaller trades.
- Adds together the fills of one bet: same wallet, same outcome, same side, within 5 minutes.
- Keeps bets at or above
minBetUsd, and by default skips trades at 97 cents and above or 3 cents and below. Those are cash parked in, or taken out of, an outcome already decided, not a view. - Looks each bettor up on Polymarket's profit leaderboard, all time and 30 days, and flags smart money when either rank is inside your cut-off with positive profit.
Pricing
| Event | Price | When |
|---|---|---|
whale_bet | $0.005 | a bet at or above your minimum |
smart_money_bet | $0.02 | the same, from a wallet inside your smart money cut-off |
A run with no new bets returns nothing and costs nothing. Raise minBetUsd or turn on onlySmartMoney to receive and pay for fewer, stronger signals.
Notes
- Smart money means a track record, not inside knowledge. Leaderboard rank measures past profit on Polymarket. It is a signal, not a guarantee, and a wallet is not a named person.
- Losing wallets are reported too. A large bet from a wallet deep in the red is its own signal; some traders fade them.
- Polymarket only. Kalshi's public trade feed has no size filter and does not identify traders, so it cannot answer "who is betting big".
