MLB: Doubles Leader

Platform comparison

Active sub-markets

Market context

The market resolves to the MLB player who finishes the 2026 regular season with the most doubles, a counting stat that tends to reward full-season availability, gap power and high plate appearances rather than pure home-run output. Early leaderboards are volatile at this stage of the season: the current names near the top include Ernie Clement and Matt Olson on 16, with several others close behind. A 9% yes price implies the market is treating the eventual winner as a long shot, which is consistent with the fact that doubles leaders often emerge from a crowded field and can be displaced by a hot month or an injury-free run.

For traders, the main watchpoints are playing-time and lineup context rather than a single headline injury. Players on contending teams with strong on-base profiles can accumulate extra doubles through volume, while weather, ballpark factors and midseason promotions can also shift the table. Official MLB stat pages and major outlets such as ESPN and CBS update the race daily, so any move in the market is likely to follow leaderboard changes, not just home-run totals. On the funding side, this kind of low-priced, leaderboard-driven market typically gets deeper only when deposits are easy enough to make quickly; lower-friction rails such as Klarna, SEPA and USDC tend to support more frequent top-ups and faster re-entry, which can matter when traders are reacting to short-lived changes in the doubles race.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
