Kalshi vs BetRivers — where the EV lives
Kalshi is an event-contracts exchange — sports outcomes trade as YES/NO contracts at user-set prices. BetRivers is a state-licensed sportsbook — you're betting against the house at vigged prices. The structural difference means Kalshi and BetRivers 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.
