MLB: Doubles Leader

Platform comparison

Active sub-markets

Market context

The event is which MLB player finishes the 2026 regular season with the most doubles. Early leaderboards are volatile: by mid-May, StatMuse had Matt Olson on top with 16 doubles, while ESPN’s season stat leaders showed Otto Lopez, Xavier Edwards, Luis Arraez and Riley Greene clustered near the top of the broader batting table. That kind of profile matters because doubles leaders are often contact-heavy regulars rather than pure power bats, and the race can swing on batting order stability, park factors and whether a player keeps getting everyday plate appearances. A 9% crowd-implied chance for any single Yes outcome is consistent with a wide-open field rather than a clear favourite. In comparable MLB season-long markets, the eventual winner is often not the opening leader in May, because gap hitters can be overtaken by players who stay healthy through the summer and rack up extra-base hits in high-volume roles.

For traders, the main catalysts are injuries, lineup promotion, and schedule density, especially around road trips into bigger outfields and stretches against weaker pitching. Team announcements on rest days or platoon usage can matter more here than headline power numbers. MLB’s own stat pages and major outlets such as ESPN update leaderboards daily, so movement is usually visible quickly; if a player on pace for the lead misses time, the market can reprice sharply. From a regulatory and access perspective, German GlüStV rules can make these contracts problematic for users in Germany depending on local gambling classification, while the US CFTC may still view event contracts through its own derivatives framework, even when a platform is accessible abroad. “No-KYC up to $1,500” means a user can often deposit, trade and withdraw within that limit without full identity checks, but it does not remove geo-blocking, tax reporting, source-of-funds checks above thresholds, or eligibility limits for this specific market.

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

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.

FAQ

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does it cost to trade on PolyGram?

Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram triggers a quick verification flow that finishes in minutes.
