PolySift is a discovery and ranking tool for Polymarket prediction markets. It scores every active market on how accessible it is to trade — factoring in volume, liquidity, time horizon, and price quality — so you can quickly find markets that are actually worth participating in, rather than sifting through hundreds of thin or phantom listings.
Each market receives an Accessibility Score from 0 to 100, computed from four weighted components:
VOLUME — 25%
Measures 24-hour trading volume. Markets with $100K+ daily volume score highest. Low-volume markets are harder to enter and exit at fair prices.
LIQUIDITY — 35%
Combines bid-ask spread (60%) and order book depth (40%). Tight spreads and deep books mean you can trade meaningful size without moving the price against you.
TIME HORIZON — 20%
Markets resolving in 7–90 days score highest. Too short and you can't react; too far out and capital is locked up with more uncertainty.
PRICE QUALITY — 20%
Prefers prices in the 0.20–0.80 range where there's meaningful room for price movement in either direction. Extreme prices (<5% or >95%) score lowest.
