Head to head, Kalshi had the better moneyline price on 58.4% of 20,055 markets where both books quoted the same game, across 361 games in the last 7 days. DraftKings had it on 46.8%, and the two posted the identical price on 5.1% of the prices compared, which is why the shares add to more than 100. Across the 6 major US books together, FanDuel leads, and that is neither book here. Both are true, and which one matters depends on how many books you actually have.
Measured September 24, 2026 across a 7-day window and recomputed as the scanner runs. Comparison set: DraftKings and Kalshi only.
A market counts here only when both books quoted that same side of that same game at the same line. Anything either book skipped is thrown out, so neither is credited for coverage the other did not have. That is the whole point: it is the only way to compare two books on price rather than on how many markets they choose to post.
Where both books posted the identical number, both are counted as best, which is why the two percentages sum above 100. On this pair that overlap is 5.1% of the prices compared, so on roughly 5.1 in every hundred there was nothing to choose between them.
No, and the site's whole position is the opposite. No single book has the best odds, and the leader depends entirely on which books you compare: this page is that argument at two books. Kalshi leading DraftKings says nothing about either against a third book, and the best price on any individual game routinely sits somewhere else again. The useful move is to hold both and take whichever is better on the bet you actually want.
