MLB: RBIs Leader

Platform comparison

Active sub-markets

Market context

The 2026 MLB regular season will crown a single player with the most runs batted in across all 162 games. RBI totals typically range from 110 to 140 for league leaders in modern baseball, though this varies with team offensive output, lineup construction, and injury patterns. The settlement mechanism includes tiebreaker rules cascading through home runs, then batting average, reflecting MLB's official statistical hierarchy.

Historical RBI leaders over the past decade reveal clustering around established sluggers in high-powered offences. Aaron Judge, Juan Soto, and Kyle Schwarber have dominated recent seasons, with leaders frequently accumulating 120–135 RBIs. However, the 2026 landscape remains fluid: player movement through free agency, age-related performance shifts, and team roster construction will reshape competitive advantage. A trader monitoring this market programmatically should track winter roster transactions, spring training metrics, and early-season pace data through April and May, when sample sizes become meaningful enough to project full-season trajectories.

Catalysts include MLB's off-season free-agent signings (typically concluded by January), spring training performance reports, and the opening day lineups that determine batting order stability. Early-season injury reports carry disproportionate weight—a star player missing 30 games materially reduces RBI opportunity. Conditional order logic could weight entries based on team offensive rankings published by analytics outlets like Baseball Savant, whilst tracking plate appearance rates and runners-in-scoring-position frequency as leading indicators of RBI accumulation potential.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
