Our win probability next to the Kalshi price, every game today and tomorrow · built Oct 4, 9:38 PM ET · schedule as of Oct 4, 9:10 PM ET

What the number is, and how good it is. The win % is a point-in-time team Elo (K=5, home field 24 Elo, constants fit on 2014-22 only) plus a starting-pitcher adjustment: each probable starter's rolling game score against his team's rotation, the FiveThirtyEight construction. On 2023-25 games it never saw it scores Brier 243.6 mB with 56.4% picked right (n=7420). Against the price it is level within the band, not ahead: vs the Kalshi T-6h mid (2025-04-16 to 2026-09-22) +0.6 mB [-0.7, +1.9], n=4075 games over 362 days (positive = worse than the market). This is not an edge claim. The model on this page has not beaten the price (the margin and its band are stated above), and nothing here sizes a bet.

"Kalshi" is the latest observed bid/ask mid, de-vigged across the two legs where both are quoted, and links to the market; the scored benchmark above is the T-6h mid, not this. Run line is the Kalshi 1.5-run spread on the side nearer even money; Total and F5 total are the strikes priced nearest 50¢ (the market's own line); F5 spread is the first-five-innings spread strike nearest 50¢ (Kalshi lists 1.5 and 2.5 only). SP is the probable starter listed now (ESPN; MLB's Stats API for earlier seasons); the number beside him is his adjustment in Elo points. Records are this regular season's.
