Market context
The Mets and Nationals meet again in Washington after a short run of one-sided results between the two clubs. Washington has already taken back-to-back wins in this series, beating New York 14-2 on 29 April and 9-6 on 19 May, so the current 0% YES price is not a statement about a mismatch in every meeting, but about how rarely the market sees New York priced as an outright underdog in this spot. The head-to-head form matters because the Nationals have found enough offence against this pitching staff to turn recent games into high-scoring affairs rather than tight one-run contests.
What traders should watch is the confirmed starting pitcher line-up and whether either club rests regulars after a quick turnaround in the schedule. The latest ESPN game reports point to Washington’s recent ability to cash in late innings — James Wood’s inside-the-park grand slam featured in the 19 May win — while New York’s bullpen has been forced into damage control in both recent defeats. Any late injury note or batting-order change, especially around the top of the Mets’ order, would be more relevant here than the broader season records, because the market is effectively asking whether Washington can repeat its recent matchup edge rather than whether either club is generally stronger over 162 games.
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.

- 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.
