Where NCAAF prices disagree.
NCAAF is priced two different ways at the same time: traders set it on Kalshi and Polymarket, and the sportsbooks set it themselves. When the two disagree far enough to survive the fees, it lands here.

The 30 most recent of 127. Every percentage is what the quoted prices implied at the moment we saw them, after fees and after the cost of your own order moving the book. Nobody placed these, and nothing already written is ever recalculated. The whole record across every sport is on the log.
Reading an NCAAF gap
A gap means backing one side on a prediction market and the other side at a sportsbook, splitting a stake between them so both outcomes pay back more than you put in. The percentage is what is left after Kalshi’s per-contract fee, Polymarket's 2%, and the price movement your own order causes, with the rounding running against the estimate.
It is an estimate from public prices at a moment in time, not a guarantee. A gap can close while you are placing the second order, and a half-filled pair is a one-sided bet rather than a hedge. The walkthrough runs the arithmetic end to end, and today’s live NCAAF board is on the front page.
