MLB odds — frequently asked questions
What MLB markets does Kalshi offer?
Kalshi currently lists 37 MLB game lines across 74 markets, plus championship, conference, division, MVP, and award futures depending on the season. SportsBookISH tracks every Kalshi market alongside 12 US sportsbooks so you can see where Kalshi is priced cheaper or more expensive than the books.
Where is the biggest Kalshi edge in MLB right now?
Seattle currently shows the largest pricing gap on Kalshi, -1.7 percentage points different from the sportsbook consensus. Edges shift constantly — refresh this page for the latest snapshot.
How often do MLB odds update?
Kalshi prices are pulled every 5 minutes via the public Kalshi REST API. Sportsbook lines refresh every 15-30 minutes. References older than 30 minutes are filtered out so you never see stale comparisons on this page.
What's the difference between Kalshi and traditional sportsbooks for MLB?
Kalshi is a CFTC-regulated event-contract exchange — you buy YES or NO contracts that settle at $1 or $0. Sportsbooks set prices and bake in a vig (typically 4-8% on game lines). Kalshi's fee is max(1¢, ceil(0.07 × p × (1-p) × 100)) capped at 7¢ per contract. When Kalshi prices a side cheaper than the no-vig book consensus, that's a +EV opportunity.
Are MLB futures available on Kalshi?
Yes. SportsBookISH tracks championship, conference, division, MVP, award, and (where applicable) win-total futures markets for MLB. Pro and Elite subscribers get full per-book pricing on every futures market; free users can see game-line comparisons.
Is betting on MLB on Kalshi legal in my state?
Kalshi operates as a federally-regulated exchange under the CFTC, which means it's legally accessible from all 50 U.S. states (unlike most sportsbooks, which are state-by-state). A handful of states have raised challenges to specific market types — always check Kalshi's current state availability page before trading.
