How to find insiders on Polymarket

1. 1

   Pick markets where someone knows the answer early

   Insider-style trades cluster in decision markets: an appointment, a court ruling, a product launch, a central bank decision, a military strike. A handful of people learn the outcome before everyone else.

   By hand

   Browse Polymarket for events decided by a person or a small group, and skip markets settled by a public count such as sports scores or vote tallies.

   With PolyScope

   Add the event in Markets, or point Insider Radar at the decision markets you care about.

2. 2

   See who is building a position

   What matters is who is adding size right now. A wallet that goes from nothing to a large position in a day stands out more than an old whale sitting still.

   By hand

   Open the market's holders tab and check it again later. It lists only the top holders, so smaller wallets growing fast stay out of view.

   With PolyScope

   Insider Radar samples the full holder table every 15 minutes and ranks wallets by 24-hour position growth and their share of the outcome's growth.

3. 3

   Check how old the wallet is

   A wallet created or funded days before a big bet, with little or no history, is the most common pattern in the cases we have looked at.

   By hand

   Open the trader's Polymarket profile and look at when it started trading and how many markets it has touched.

   With PolyScope

   Fund tracking shows when the wallet was first funded and from where. Wallet cards show its PnL and closed positions.

4. 4

   Look at the entry price and the size

   Buying at 5 to 20 cents means the crowd thinks the outcome is unlikely. A large position at those odds, far bigger than the wallet's usual bets, is a strong signal.

   By hand

   Read the wallet's trade history and compare this bet with its earlier ones and with the market's liquidity.

   With PolyScope

   Every wallet alert carries the entry price and size. Market alerts fire on large trades and on jumps in open interest, volume or price.

5. 5

   Compare the timing with the news

   Positions that build in the last hours or minutes before an announcement are harder to explain than ones opened weeks earlier.

   By hand

   Write down when each buy happened and compare it with the time the news came out.

   With PolyScope

   Alerts arrive as soon as a trade settles on-chain, so you see the entry while the news is still ahead.

6. 6

   Follow the money

   Where the deposit came from often tells more than the trade. Money from an exchange an hour before the bet, or from an older wallet with a record on the same topic, links the dots.

   By hand

   Open the wallet on a block explorer, find the deposits and trace them back. Bridges and hops between chains make this slow.

   With PolyScope

   Fund tracking follows deposits across Ethereum, Arbitrum, Base and other chains, resolves bridges to the wallet that actually sent the money and shows where withdrawals went.

7. 7

   Look for more than one wallet

   Several new wallets entering the same outcome within a day is a pattern of its own. People with the same information tend to act at the same time.

   By hand

   Compare the holders who arrived around the same time and check whether their profiles look alike.

   With PolyScope

   Insider Radar ranks every growing holder of the outcome together, so several fresh wallets moving at once show up side by side.

None of this proves intent. Plenty of large bets from new wallets come from ordinary traders using a fresh address, so treat a wallet that matches several steps as a reason to look closer.
