Market context

The Detroit Tigers face the Cleveland Guardians on 13 June at 4:10PM ET in an AL Central matchup. Current crowd-implied probability sits at 56% for a Tigers victory, suggesting marginal favouritism. The settlement window extends to 20 June at 20:10 UTC, allowing for postponement contingencies common in early summer baseball scheduling.

Historical performance between these franchises provides useful calibration. Over the past three seasons, the Tigers have won roughly 48% of head-to-head contests against Cleveland, though 2024 divisional records shifted considerably following Cleveland's mid-season acquisitions. The Guardians' bullpen depth and defensive metrics ranked top-five in MLB last season, whilst Detroit's pitching staff showed volatility. A 56% probability for Tigers victory reflects genuine uncertainty rather than decisive edge—comparable to markets where home-field advantage and recent form roughly offset roster composition differences.

Traders should monitor starting pitcher announcements (typically confirmed 48–72 hours pre-game), injury reports on key position players, and weather conditions at Comerica Park. Detroit's recent offensive trends and Cleveland's performance against left-handed starters warrant programmatic tracking via MLB's official API feeds. Conditional order logic might weight pitcher matchups heavily, as Detroit's rotation depth has fluctuated. The 7-day settlement window provides sufficient buffer for postponement scenarios, though cancellation without make-up games would trigger 50-50 resolution per market terms. Real-time line movement across major sportsbooks often precedes material news; monitoring closing-line value becomes relevant for algorithmic evaluation.

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

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.
