Cost
Across 2055 two-sided player-prop markets Kalshi currently prices, the two sides add up to about 8.24% above a fair 100% — that gap is Kalshi's hold. One-sided markets are excluded from this figure because there is no second price to add against the first.
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 vs DraftKings
Kalshi and DraftKings do not currently overlap on enough live props to compare head to head.
What Kalshi is
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 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.
Because a Kalshi quote is already close to a probability, the edge shows up when a sportsbook has not moved a prop that Kalshi traders have already repriced.
