Detroit Tigers vs. Baltimore Orioles

Platform comparison

Active sub-markets

Market context

Polymarket has this Tigers–Orioles contract at about 45% YES, so the crowd is leaning slightly towards Detroit despite the split pre-game pricing elsewhere. On Polymarket, that means USDC is being used to buy conditional tokens that settle to the winning side once the official result is posted on Polygon. With the market resolving on the final MLB result, the key question is simply which club takes the game, not run line or total outcomes.

Recent comparable pricing points to a fairly modest edge rather than a strong conviction. OddsIndex noted Baltimore around -127, with the market implying roughly a 55.9% home win chance, while Polymarket’s 45% YES price suggests traders are effectively asking whether Detroit can outperform that baseline. That sort of gap is common when one venue is shading towards the home side but the exchange crowd is factoring in broader form, lineup volatility, or late-market uncertainty. The relevant read-through is that the contract is not pricing a blowout assumption, just a narrow lean.

The main catalysts are ordinary but important: confirmed line-ups, any late pitching change, and whether the game starts on schedule at 7:15 pm ET. Because this is an MLB moneyline-style binary resolution, any postponement would keep the market open until completion, and a cancellation or tie would settle 50-50 under the contract rules. A recent preview on OddsIndex highlighted Detroit’s offensive slump as a suppressor, while FanDuel and Kalshi both show the market is still treating this as a competitive game rather than a clear mismatch.

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

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.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
