Insider Finder — Suspected Insider Trades on Polymarket

The Insider Finder surfaces Polymarket trades that exhibit statistical signatures consistent with informed (or insider) activity. Each candidate trade is scored 0–100 by a composite engine combining six signals: wallet age (younger wallets are more suspect), unique markets traded (focused wallets are higher signal), trade size in USDC, single-market conviction (concentration of capital), fresh CEX funding (clean wallet appears, deposits, immediately bets), and market niche (low-volume markets are more likely to host informed flow).

Polymarket only — Kalshi is centralized and does not expose comparable on-chain signals. When a similar Kalshi market exists, the Insider Finder shows the spread between the Polymarket YES price and the Kalshi YES price as an inline cross-reference. A wide spread accompanying a high Insider Score may indicate an arbitrageable view.

How to read a flag

Each card shows the wallet address, market, side and price, USDC size, the composite Insider Score, and a short rationale (e.g. "Wallet only 4d old · $25,000 bet · only 1 market traded · fresh CEX funding"). Click into any wallet for its on-chain history, score breakdown, and a simple copy-trade backtest.
