Head to head

Kalshi vs FanDuel — NBA

Which venue is currently the cheaper side of the same NBA props, de-vigged and counted live.

See every live edge

Right now BeatVig prices 87 NBA props at both. Kalshi is the cheaper side 89% of the time (78 of 87), and FanDuel is cheaper on 9. This is the board as it stands at 31 Oct 19:35 ET, not an average over any period — BeatVig measures live prices and keeps no price history.

How they differ

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.

How each one charges

Kalshi
Kalshi is a CFTC-regulated exchange. Every contract settles at $1 or $0, so a 42¢ quote is a 42% implied probability with no sportsbook margin layered on top.
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.
Kalshi lists player markets as "X or more" yes/no contracts rather than as an over/under line, so BeatVig converts each contract to the equivalent over price before comparing it to a sportsbook number.
FanDuel
FanDuel is a traditional sportsbook: it sets the line and prices both sides with its margin included rather than matching you against another bettor.
FanDuel's margin is inside the price, so it is charged on every bet regardless of the result.
FanDuel prices a broad US player-prop menu across the major leagues.
