Market context

The Detroit Tigers and Baltimore Orioles are scheduled to play in Baltimore on 22 May at 7:15pm ET, and the market will settle on the official final result once the game is completed. At a crowd-implied 45% for Detroit, the pricing is broadly consistent with a close matchup rather than a strong home or away edge. If the game is postponed, the market stays open until the make-up is played; if it is cancelled outright or ends tied, it resolves 50-50.

For context, single-game MLB markets often move sharply on confirmed starting pitchers, late lineup changes and weather, especially when a club has just produced a lopsided result. Detroit’s recent sweep of Baltimore, including Tarik Skubal’s six shutout innings in the series finale, is a useful comparable for how quickly sentiment can swing after one dominant outing, though it does not determine this game. For accessibility, “no-KYC up to $1,500” means smaller positions can usually be taken without identity verification, while larger activity may trigger checks; in German terms, GlüStV rules can matter for residents accessing gambling-style products, and US CFTC reach is relevant where a platform or participant falls under US derivatives or event-contract oversight.

Traders should watch for the confirmed starter pairings, any rest days after the previous series, and whether Baltimore’s home field is affected by weather or schedule changes. A recent postgame report on the Tigers’ sweep highlighted Skubal’s performance and the broader momentum shift, but the main near-term catalysts remain line-up announcements and pitching updates rather than narrative alone. Because this market resolves on the game’s official result, any postponement or rescheduling before first pitch is more important than pre-game chatter.

Methodology

We track Detroit Tigers vs. Baltimore Orioles on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.

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.
