Basketball
Where NBA prices disagree.
NBA is priced two different ways at the same time: traders set it on Kalshi, and the sportsbooks set it themselves. When the two disagree far enough to survive the fees, it lands here.
Where NBA gets priced
- Prediction markets
- Kalshi — Polymarket lists no NBA game markets, so there is no second prediction-market price to compare against.
- Sportsbooks
- DraftKings, FanDuel, BetMGM, BetRivers
What we have recorded
Nothing logged in NBA yet. Gaps show up when the venues disagree, and on plenty of days in plenty of sports they simply do not. Whatever turns up gets written here rather than filled in to make the page look busier.
Reading an NBA 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 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 NBA board is on the front page.
