AJ Dybantsa market shows the largest price gap between Kalshi and Polymarket.
WinDailySports tracked the biggest cross-venue gaps on its October comparison board, which refreshes about every 40 minutes. Georgia for the College Football National Championship showed the next largest gap, at 15 cents on Kalshi against 20 cents on Polymarket.
WinDailySports’ October comparison board showed its largest Kalshi-Polymarket price difference in the NBA Rookie of the Year market, with AJ Dybantsa priced at 17 cents on Polymarket and 11 cents on Kalshi.
The report, published Oct 31, 2026, at 12:30 PM ET, put the difference between those prices at 6 cents.
Georgia follows with a 5-cent difference
The next-largest gap involved Georgia in the College Football National Championship market, according to WinDailySports. Georgia was priced at 15 cents on Kalshi and 20 cents on Polymarket, a difference of 5 cents.
Polymarket therefore carried the higher price in both comparisons. The Dybantsa gap exceeded the Georgia gap by 1 cent.
A periodically refreshed comparison
WinDailySports tracks cross-venue differences on an October comparison board that refreshes about every 40 minutes. The reported rankings represent that comparison rather than a continuous measure of the two venues.
What it means for prediction markets
- The largest reported price disagreement was in NBA Rookie of the Year: 17 cents for AJ Dybantsa on Polymarket versus 11 cents on Kalshi.
- Georgia’s championship prices showed a smaller but similarly directed difference, with Polymarket 5 cents above Kalshi.
- The roughly 40-minute refresh interval matters when interpreting the rankings: the reported gaps do not establish that those differences persisted between updates.
