MLB: RBIs Leader

Platform comparison

Active sub-markets

Market context

The 2026 MLB regular season will crown a single leader in runs batted in (RBIs)—the cumulative statistic measuring how many runners a batter drives home. This market resolves to that player on 28 September 2026, with tiebreakers cascading through home run total, then batting average. Historical RBI leaders typically accumulate 120–140 RBIs across a 162-game season; Aaron Judge led MLB in 2022 with 131 RBIs, whilst Juan Soto and Mookie Betts have consistently ranked in the top five. The 2026 favourite will likely emerge from established sluggers with both power and consistent plate appearances, though injuries or mid-season trades can reshape the leaderboard substantially.

Traders should monitor spring training performance and opening-day rosters closely, as early-season form often signals sustained production. Team offensive depth matters considerably—a player batting in a weak lineup generates fewer RBI opportunities than one in a stacked order. Recent roster moves, free-agent signings, and injury reports from November 2025 onwards will clarify which teams field the most potent lineups. The settlement window closes at the end of the regular season, meaning liquidity and funding flows on this market will intensify as summer approaches and the statistical race tightens. Deposits via Klarna, SEPA transfers, and USDC settlement rails will determine book depth; markets with higher deposit friction typically show wider spreads and slower price discovery.

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
