What market movers show
On Polymarket, each binary market has an implied probability that the Yes outcome pays $1. That mid is shown here as Yes%. Over a window (1h / 24h / 7d) that probability can rise or fall as traders reprice the book. Δpp is that change in percentage points — if Yes went from 40% to 55%, Δpp is +15pp, not “+37% relative.”
Gainers are markets where Yes% increased the most versus a Yes-side reference fill near the start of the window. Losers are where Yes% decreased the most. A large move can mean news, sports results, thin liquidity after a game, or simply active two-sided trading — it is not a recommendation to buy or sell.
How to read a row
- Question — the market title; open it for overview, tape, and whale flow.
- Yes% — current implied Yes (research mid from indexed prices / Yes fills).
- Δpp — Yes% now minus Yes% near window start (percentage points).
- Vol — USD traded in the volume window used for the liquid universe filter (not the same as lifetime volume on every screener row).
- Bookmark (Save) adds the market to your research watchlist in this browser only.
Coverage and limits
Universe: open markets with enough window volume (≥ $5k) and a usable Yes (token1) reference fill. Near-certain books (Yes below ~3% or above ~97% at either end of the comparison) are dropped so settlement dust does not dominate the ranking. Data can lag the Polymarket UI by a short interval.
