Baltimore Orioles vs. Los Angeles Dodgers

Market context

Polymarket has this Orioles–Dodgers moneyline contract trading at **100% YES**, which implies the market is effectively locked on a Baltimore win rather than the broader baseball setup. On Polymarket, buyers use **USDC** on **Polygon**, and the contract is a **conditional token** that settles against the official result, so the only thing that matters for final payout is which side is recorded as the winner. The game itself is scheduled for June 21 at 4:10pm ET, with the settlement window running until 2026-06-28T20:10:00Z if the fixture is delayed or rescheduled.

For context, that pricing sits well away from the pre-game consensus elsewhere: Polymarket’s own market page has listed the Dodgers around **67¢**, while external preview odds also leaned towards Los Angeles, including ESPN’s game listing and Fox Sports’ box score page, both tying the matchup to a Dodgers-favoured pre-game setup.[6][5][2] In practical terms, a 100% reading on Polymarket usually reflects either a completed result being embedded in the contract state or an extremely one-sided live pricing environment; traders should treat it as a final-resolution signal, not a normal pre-match probability, until the official MLB stat line is checked against the contract rules.[6][5]

The key catalysts are procedural rather than tactical: any postponement, suspended game, or schedule change keeps the market open until completion, while a cancellation with no make-up or a tie would resolve 50-50 under the rules. Traders watching the on-chain position should therefore focus on the official MLB final score, any league announcement on resumption or make-up timing, and whether the game reaches a recognised final rather than relying on third-party scoreboards alone.[8][5]

Methodology

We track Baltimore Orioles vs. Los Angeles Dodgers 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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
