MLB: Runs Leader

Platform comparison

Market context

The underlying event is the player who accumulates the highest total of runs during the 2026 Major League Baseball regular season, with the market currently assigning a 24% probability to Shohei Ohtani leading this category. Historically, run totals are heavily correlated with batting average and on-base percentage rather than pure power, meaning the frontrunner for home runs like Aaron Judge or Kyle Schwarber often trails the actual runs leader, who is typically a high-contact hitter with elite speed or consistency. In recent seasons, players like Mookie Betts or Freddie Freeman have led in runs despite not topping the home run charts, suggesting the current 24% odds for Ohtani reflect his dual-threat capability but may underestimate the volatility of contact-heavy leaders who score more frequently through walks and steals.

Traders approaching this programmatically should monitor daily lineup announcements, injury reports for key pitchers, and Ohtani’s plate appearance frequency, as runs are a function of time on base and opportunity. A critical catalyst is the mid-season schedule shift in July, when teams face varying pitching rotations that can inflate or deflate run totals for specific players; recent analysis from Yahoo Sports notes that Aaron Judge’s power odds remain strong for home runs, yet his run-scoring consistency depends on lineup protection and batting average trends that fluctuate weekly[2]. Conditional orders should be triggered by Ohtani’s batting average dropping below 0.280 or his on-base percentage falling under 0.350, as these metrics directly correlate with run accumulation and would signal a shift in market probability toward more consistent contact hitters like Otto Lopez, who currently leads in batting average and hits[3].

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Review UK, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
