Market context

The underlying event is the team that wins the 2026 MLB World Series, a contest concluding in late October 2026. Current crowd-implied probability sits at 15% for the "YES" outcome, reflecting a market where the Los Angeles Dodgers lead as favourites with +180 odds, followed by the New York Yankees at +470 and the Atlanta Braves at +950[1][3]. This 15% figure aligns with historical precedents where top-tier contenders like the Dodgers, who won in 2024 and 2025, hold roughly 27–30% implied chances across major platforms, suggesting the current market is slightly undervalued relative to established betting consensus[3][8].

Traders should monitor the 2026 MLB regular-season schedule, playoff elimination dates, and any official announcements regarding team health or roster changes, as these directly determine resolution to "No" if a listed team is eliminated[1]. Recent reporting from FanDuel confirms the Dodgers remain the primary betting favourite, making their performance a critical catalyst for probability shifts[1]. Regulatory accessibility is shaped by German GlüStV implications and US CFTC reach, where "no-KYC up to $1,500" allows retail participants to access this market without identity verification, provided transactions stay within that threshold, enhancing liquidity for smaller traders while maintaining compliance with anti-money laundering standards.

The settlement window ends 2026-10-31, and if the season is cancelled or postponed after December 31, 2026, the market resolves to "Other". This structure mirrors standard prediction market frameworks where external disruptions trigger alternative outcomes, ensuring clarity for participants. The market’s design prioritises official MLB data as the primary resolution source, with credible reporting serving as a secondary consensus mechanism, reinforcing reliability for legal and tax reporting purposes.

Methodology

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

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.
