Where is the biggest Kalshi edge in MLB right now?

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.
