MLB: Doubles Leader

Platform comparison

Active sub-markets

Market context

Matt Olson has opened up a narrow early lead in the doubles race, with 16 on the season, just ahead of Ernie Clement and Riley Greene on 15. That leaves the market still highly open this early in the campaign, which fits the low 9% implied chance on any one player. Through roughly 50 games, the leaderboard is being driven by a small number of hot starts rather than a locked-in season-long frontrunner.

Recent seasons show that doubles titles often turn on volume, contact quality and health more than on pure power. A player can sit near the top in May and still be overtaken quickly if another regular keeps stacking line drives and gaps hits over 150-plus games. Early leaders also tend to be vulnerable to regression, while durable everyday bats from strong line-ups can build totals steadily after the first two months.

The main things to watch are playing time, batting order security and any injury or rest news, especially for players already in the top five. MLB’s official stats page and live leaderboards are the best reference for the running race, and the standings can change quickly once teams start stringing together road trips and divisional series. Because the settlement window runs to 11 October, the race is likely to reward consistency over the summer rather than the player with the biggest May burst.

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

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.
