Houston vs New York M

This event tracks a three-game MLB series between the Houston Astros and New York Mets, with contests scheduled between August 28 and August 30, 2026. Kalshi has fielded the bulk of the offering, with dozens of markets covering game winners, spreads, first-3/first-5/first-7 inning results, team and player totals, and pitcher strikeouts. Polymarket lists the moneyline and player-prop books for the August 30 matchup, while Gemini carries player hit and home-run markets. On the headline moneyline for the August 30 game, the Mets are the current favourite at 53.5%, priced at 53.5% on Polymarket US, 54.0% on Kalshi, and 54.0% on Polymarket — an unusually tight cross-platform picture. The Astros sit just behind at a 46.8% consensus (Kalshi 47.0%, Polymarket US 47.0%, Polymarket 46.0%). That margin, under five points, signals a close-to-coinflip contest rather than a clear edge. Cross-platform spreads on run totals and player props are mostly within a point, though the Over on the game total shows a 0.75-point gap, with Polymarket US at 62.5% versus Polymarket at 61.5%. Overall, the platforms are aligned: a narrow Mets lean in a matchup the market treats as close to even.
