Detroit Tigers vs. Pittsburgh Pirates

Platform comparison

Market context

The Detroit Tigers face the Pittsburgh Pirates on 18 August at 6:40PM ET in a regular-season MLB matchup. Polymarket currently prices a Tigers victory at 42%, reflecting modest confidence in Detroit despite their positioning within the AL Central. The settlement window extends to 25 August, allowing for postponement resolution should weather or scheduling complications arise before the game concludes.

Detroit enters August as a rebuilding franchise with inconsistent performance across 2024, whilst Pittsburgh operates as a perennial lower-tier competitor in the NL Central. Historical matchups between these clubs show relatively balanced outcomes when accounting for roster strength, though the Tigers hold marginal advantages in recent seasons. The 42% probability suggests the market perceives meaningful uncertainty, pricing neither team as a clear favourite despite Detroit's nominal superiority in win-loss records and offensive metrics.

Traders should monitor roster updates through game day, particularly injury reports affecting starting pitchers and key position players. Recent trades or call-ups from either organisation's minor league system could shift conditional token valuations if announced before 18 August. Weather forecasts for the venue merit attention given the settlement clause's postponement provisions—extended rain delays would keep the contract open beyond the initial window. Line movement on external sportsbooks may signal sharp money repositioning, though Polymarket's USDC-denominated pricing on Polygon operates independently of traditional betting markets.

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 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.
