Kalshi vs FanDuel — where the EV lives

Kalshi is an event-contracts exchange — sports outcomes trade as YES/NO contracts at user-set prices. FanDuel is a state-licensed sportsbook — you're betting against the house at vigged prices. The structural difference means Kalshi and FanDuel regularly disagree by 3-10pp on the same market.

SportsBookISH overlays both side-by-side so the gaps are visible without manually pulling up two apps. Median absolute gap on major-league moneylines is around 3-4pp; the tails (10pp+ divergences) appear in roughly 5% of open markets and are usually where the meaningful edge sits.

FAQ

What is Kalshi?
Kalshi is a CFTC-regulated event-contracts exchange. Users buy and sell YES/NO contracts on real-world outcomes — including sports — at market-set prices. There's no traditional sportsbook vig; the spread is bid/ask between users.
Is Kalshi better than FanDuel?
Different products. FanDuel is a sportsbook with the house as counterparty (vig built in). Kalshi is an exchange (no house). Kalshi prices often beat FanDuel's no-vig fair line by 2-8pp on regular-season major-league moneylines, and the gap widens on futures.

What's the typical Kalshi-vs-FanDuel edge?
