New York Mets vs. Washington Nationals

Market context

The New York Mets and Washington Nationals are due to play at 4:05pm ET, and the market settles on the official result of that game, with a 50-50 outcome only if it is cancelled outright or ends tied. A 1% YES price implies the Mets are already treated by the crowd as an overwhelming favourite. That sort of pricing usually reflects a combination of team strength, probable pitching and venue, rather than any expectation that the market is mispriced.

For context, Mets-Nationals games have often been one-sided when New York has had the stronger rotation or line-up, but baseball remains sensitive to starting pitcher scratches, late batting-order changes and bullpen usage across a series. Under German GlüStV, access to sports wagering products can be materially more restrictive than in the US, while the US CFTC does not automatically regulate every event contract in the same way as a traditional sportsbook. On a venue offering no-KYC up to $1,500, the practical effect is that smaller positions in this specific market are generally more accessible without identity verification, but higher activity may still trigger checks.

The main catalysts to watch are confirmed starters, any last-minute rest decisions and whether the game goes ahead on schedule. If there is a postponement, the contract stays open until the makeup is played; if there is no makeup, the 50-50 fallback applies. ESPN’s game listing shows the fixture on 21 May, while the market window itself runs to 28 May, so any weather delay or scheduling change would matter more here than in a standard same-day cash-out context.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.

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.
