Boston Red Sox vs New York Yankees

The Boston Red Sox host the New York Yankees in a regular-season MLB matchup scheduled for the evening of September 30, 2026, with the game currently live. Because the two rivals draw heavy market attention, dozens of side markets are listed alongside the moneyline — spreads, totals, inning-by-inning winners, player props, first-5 and first-3 innings markets, and an extra-innings market — spread across Kalshi, Polymarket, Novig, Gemini and Azuro. Novig alone accounts for roughly $669k of the event's ~$1.07M in volume, making it the primary price discovery venue for the headline moneyline. On the full-game moneyline, the Yankees are the modest favourite at a consensus 55.3%, with Novig showing 55.5% and Azuro slightly higher at 57.8%. Boston sits at 44.8% consensus (Novig 45.0%, Azuro 48.3%). That's a narrow edge — closer to a coin flip than a clear mismatch. On totals, Kalshi has Over 6.5 runs at 54.0% and Over 7.5 at 41.0%, implying an expected run total right around 7. The most notable cross-platform gaps sit in Gemini's totals and inning markets, where several Over/Under lines diverge from Novig by 29–39 points, likely reflecting different strike levels rather than genuine disagreement. Overall, the headline market prices a tight game with the Yankees as slight favourites.
