On Polymarket the money moves before the news does. The question is how to see it move. On OrcaLayer, smart money flow is visible on three surfaces, each answering a different question.
How can I monitor smart money flows on Polymarket?
Use three views together: the Whale Alerts feed for individual moves, Big Positions for accumulated weight, and Sonar for the whole flow at a glance. All three read OrcaLayer's own index of the Polygon chain, over 1.2 billion trades, and all three are farmer-filtered, so wash-pattern wallets and bots do not pollute what you see.
Live Fills: every big trade, as it happens
The Whale Alerts feed streams every Polymarket trade of 500 dollars or more, usually less than a minute after the on-chain fill. Filter by category (crypto, sports, politics, geopolitics, economics, tech), by buy or sell side, and by size from 1,000 to 100,000 dollars and up. This is the motion view: who is buying what, right now, at what price.
Big Positions: where the weight sits
A single fill tells you little. A held position tells you where the conviction sits. Big Positions tracks accumulated holdings of 500,000 dollars or more per wallet and market, so a whale that built its stake from dozens of small fills still surfaces. Big Positions strips out the timing and shows the standing bet. A big trader who does not want to print one large fill can split the order, but the accumulated position cannot hide.
Sonar draws the whole flow as one live map
Sonar draws the same capital flow as a live scene instead of a table. Every whale trade swims in as a creature sized by its dollar amount, headed for the market it hit. Market docks show where money is concentrating, and resolving-soon countdowns mark markets about to settle. It is the fastest way to see, in one glance, which corners of Polymarket the big money is crowding into, and it runs on the same farmer-filtered on-chain data as everything else.
From a flow to a wallet
A flow is only interesting if the wallet behind it has a record. Any trade in the feed links to the wallet's profile: resolved-market win rate, realized profit, position history. The leaderboard ranks those wallets with farmers, bots, and Polymarket's router contracts removed by default. How that filter works is documented in the farmer detection guide, and if you want the raw data programmatically, the REST API on Premium serves it at 600 requests per minute.
Frequently asked questions
How can I monitor smart money flows on Polymarket? Three surfaces on OrcaLayer cover it: the Whale Alerts feed streams every trade of 500 dollars or more live, Big Positions shows accumulated holdings of 500,000 dollars or more, and Sonar draws the whole capital flow as a live map. All three are farmer-filtered.
What is OrcaLayer Sonar? A live cross-section of Polymarket capital flow. Every whale trade appears as a creature sized by its dollar amount, swimming toward the market it hit, with resolving-soon countdowns on the docks. It is real on-chain data, farmer-filtered, drawn as a map instead of a table.
How do I see big trader moves as they happen? Open the Whale Alerts feed. It streams every Polymarket trade of 500 dollars or more, typically well under a minute from the on-chain fill, with filters for category, side, and size up to 100,000 dollars and above.
Can a whale hide by splitting a big trade into small fills? Not from position tracking. Big Positions aggregates holdings per wallet and market, so a 700,000 dollar position built from 50 small fills still surfaces once the accumulated size crosses the threshold.
Are these flow tools free? Browsing the Whale Alerts feed and Sonar is free. Personal Telegram alerts on followed wallets are on the Pro tier, and programmatic access through the REST API is on Premium.
