In a one-winner Kalshi event, buying YES on every outcome guarantees exactly one winner, so the whole field should cost about 100¢. This scan ranks live one-winner events by what the field actually costs to buy right now. Below 100¢ is a potential lock; a small premium is simply the tightest, best-value place to trade. Multi-select events (where several outcomes can happen) are excluded.
⚠ Before treating any of these as free money: the cost shown is the current ask, but filling every leg at size moves prices, Kalshi charges a trading fee per contract that can erase a thin edge, and a stale quote on a low-volume outcome can fake an underround. Verify executable asks and fees on Kalshi.
