About PolySide

What is PolySide?

PolySide analyzes every Polymarket market by aggregating the global historical PnL of wallet holders on each side (YES/NO). We score each side with a “Winner Score” — a composite metric indicating how successful its holders are historically across ALL markets, not just the current one.

Winner Score Methodology

The Winner Score (0–1) is calculated using three components:

Winner Percentage (W%)

Percentage of wallets on this side with positive global PnL across all markets.

Normalized PnL

Total PnL of this side normalized against the total PnL of the market.

Consistency

Average win rate per wallet (markets won / total markets traded).

Weights are continuously optimized through backtesting against resolved markets. Category-specific weights are applied where sufficient data exists.

Confidence Indicator

Each score includes a confidence level based on: number of wallets analyzed (30%), market volume (25%), backtesting accuracy (30%), and data freshness (15%).

Data Sources

All data comes from public Polymarket APIs (Gamma, Data, CLOB) and real-time WebSocket feeds. We analyze 60,000+ markets and discover wallets through holders, trade history, and position data.
