Compare recorded prediction-market odds across real-money venues. This cached list ranks the largest price differences on shared outcomes; its 45-minute snapshot-age filter was checked when the comparisons were computed, not when this page is viewed. Full comparison matrix →
Pairs come from reviewed cross-venue matches of the same real-world question. When computed, each qualifying pair had both markets open and substantively priced, a recorded snapshot age of at most 45 whole minutes on each side, and, when both usable contract deadlines were available, those deadlines were within 180 days of each other. The gap is the largest probability difference on an outcome BOTH venues price; a leg only one venue lists never counts. Play-money and forecast venues are excluded. Data timestamps identify CoinRithm snapshot observations, not necessarily venue quote updates or last trades. Cached results may no longer meet these conditions when viewed.
