How Insidex Detects Insider Trading on Polymarket

Pre-Resolution Detection

We monitor for large positions opened shortly before a market resolves — a classic indicator of insider knowledge about outcomes.

Information Asymmetry

We detect wallets that consistently buy low before sharp price increases — suggesting access to non-public information and systematic information advantage.

Wallet Cluster Mapping

Related wallets are grouped by behavioral similarity, timing correlations, and market overlap to reveal coordinated trading rings.

Volume Spike Alerts

Sudden surges in trading volume relative to historical averages can signal informed trading activity before public information is available.

Flash Position Tracking

Rapid accumulation of large positions in short time windows is flagged — a pattern often associated with information-driven trading.

Wash Trading Detection

Identifying self-dealing patterns where the same entity trades with itself to create artificial volume or manipulate market prices.
