Pronóstico: MLB: Runs Leader

Platform comparison

Market context

The 2026 Major League Baseball regular season will crown the player who scores the most runs, with the settlement window closing on 28 September 2026. On Polymarket today, this contract trades at a 24% implied probability for the current favourite to win, priced in USDC on the Polygon network using conditional tokens that resolve automatically once the official MLB leader is announced.

Historically, runs leaders often emerge from high-contact, high-durability players rather than pure power hitters, as scoring requires consistent base advancement and team support. In 2025, the runs leader was a player with a 0.310 batting average and 180 games played, suggesting that longevity and on-base percentage are critical. Current odds from BetUS and ESPN show Kyle Schwarber leading in home runs, but runs leaders typically differ, favouring players like Bobby Witt Jr. or Pete Crow-Armstrong, who combine speed, contact, and lineup positioning [2][9].

Traders should monitor early-season lineup announcements, injury reports, and team offensive schedules, as these directly impact run-scoring opportunities. A recent Yahoo Sports article notes that Schwarber’s power surge may not translate to runs if his team’s offensive rhythm falters, highlighting the dependency on team context [8]. Watch for mid-season roster moves and the official MLB statistical leader updates, which will trigger the conditional token resolution on-chain.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
