The prediction markets whose odds moved furthest, rising and falling, over the last hour, day or week - usually the first place news shows up. Moves are in percentage points of probability, and only markets with real trading behind them make the list.
Sources: Polymarket's Gamma API (each market's change over an hour, a day and a week) and Kalshi's event search (each market's last price against a day earlier), refreshed every minute. Only outcomes with at least $5,000 traded in the day on Polymarket, or busy events on Kalshi, are ranked: a swing on a market nobody trades is one order walking a thin book. Markets that open and settle within a day are left out.
