Head to head
Which venue is currently the cheaper side of the same NFL props, de-vigged and counted live.
Right now BeatVig prices 246 NFL props at both. Kalshi is the cheaper side 79% of the time (196 of 246), and FanDuel is cheaper on 49. This is the board as it stands at 31 Oct 12:34 ET, not an average over any period — BeatVig measures live prices and keeps no price history.
FanDuel prices a deeper prop menu than Kalshi lists, so the interesting question is not who covers more — it is who is cheaper on the props both of them price. FanDuel earns its margin on every bet you make; Kalshi charges a per-contract fee that is biggest on close-to-even markets and smallest on lopsided ones. That means the gap between them is not a constant, and the only honest way to answer it is to measure it per prop, which is what the board below does.
Counted above: every prop Kalshi prices lower than FanDuel. Listed below: the ones that also beat a de-vigged fair price, which is the stricter test and the only one worth acting on.

Go PremiumAcross the 246 NFL props priced at both venues right now, Kalshi is the cheaper side on 196 and FanDuel is cheaper on 49; the rest are priced identically at both. Neither venue is cheaper on everything, and this is a live count of the current boards rather than an average over time.
Every quote from both venues is converted to the implied probability of the same outcome, so a contract price and an American price become the same unit. The cheaper venue is the one implying the lower probability for the side you want.
Kalshi charges a per-contract trading fee instead of building a margin into the line. The fee is a curve, not a flat rake: it peaks at roughly 1.75¢ on a contract priced near 50¢ and shrinks toward zero at both extremes, and maker fees are a quarter of taker fees.
FanDuel's margin is inside the price, so it is charged on every bet regardless of the result.
It is computed from the live board every time the page loads, so it reflects the prices both venues are showing at that moment rather than a snapshot taken on an earlier day.
