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.

Go PremiumHow 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.
