MLB: RBIs Leader

Platform comparison

Active sub-markets

Market context

The 2026 MLB regular season will determine which player accumulates the most runs batted in across all games from late March through late September. RBI totals depend on both individual batting performance and team offensive context; players on high-scoring lineups typically record higher RBI counts than equally skilled hitters on weaker offensive teams. The settlement window closes on 28 September 2026, capturing the full 162-game schedule and any playoff-clinching variations in playing time.

Historical RBI leaders have typically ranged between 110 and 145 RBIs per season over the past decade, with variance driven by injury, team construction, and batting order placement. Aaron Judge led MLB with 144 RBIs in 2022; Mookie Betts and Kyle Schwarber tied at 113 in 2023. These outcomes suggest that elite power hitters on competitive teams dominate the leaderboard, though mid-season trades and lineup reshuffles can shift RBI opportunity significantly. Comparing 2026 projections to historical baselines helps calibrate whether early-season performance aligns with full-season trajectory.

Traders should monitor spring training reports, Opening Day lineups, and mid-season trade deadlines—all potential catalysts for RBI distribution shifts. Injuries to star players or unexpected roster moves can redirect RBI opportunities to secondary hitters. From a regulatory standpoint, this market operates under German GlüStV provisions where applicable and US CFTC reach for US-based traders; the no-KYC threshold of $1,500 applies to aggregate positions across all prediction markets on this platform, meaning traders can access this specific market without identity verification provided their total exposure remains below that limit. Settlement will follow official MLB records as published by the league.

Methodology

We track MLB: RBIs Leader on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.
