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 162 games, with the settlement window closing at season's end on 28 September 2026. No clear favourite has yet emerged in early market pricing, reflecting genuine uncertainty about roster compositions, injuries, and offensive output across the league's 30 teams. The RBI title typically correlates with both batting opportunity and run-scoring environment, making it sensitive to which teams field competitive lineups capable of generating baserunners.

Historical RBI leaders have averaged between 120 and 140 RBIs over recent seasons, though this varies considerably based on team strength and individual health. Miguel Cabrera's 139 RBIs in 2012 and Mookie Betts' 142 in 2018 represent recent high-water marks, whilst lower-volume seasons have seen leaders finish with 110–115 RBIs. The tiebreaker structure—favouring home run totals, then batting average—means the eventual leader will likely combine consistent plate appearances with power production and run-scoring opportunities.

Traders should monitor offseason free agency announcements through winter 2025 and spring training developments, particularly tracking which players join contending teams with strong run-scoring environments. Injuries to established sluggers or unexpected breakout performances from younger players could shift expectations materially. Recent franchise trades and managerial changes affecting batting orders will influence individual RBI accumulation rates, with teams like the Yankees, Dodgers, and Astros historically producing competitive RBI leaders.

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.

Resolution & payout

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.
