Detroit Tigers vs. New York Yankees

Platform comparison

Market context

The Detroit Tigers face the New York Yankees tonight at Yankee Stadium in a 7:05pm ET MLB contest, with the Tigers needing a win to claim the market. Current prediction-market odds imply a 45% chance for the Tigers, while major sportsbooks consistently price New York as the favourite. FanDuel lists the Yankees at -142 moneyline and the Tigers at +120, translating to a 55.8% win probability for New York according to numberFire[1]. ESPN similarly shows the Yankees at -132 and the Tigers at +132, reinforcing the sportsbook consensus that the home side holds a distinct edge[2].

Historically, when prediction markets diverge meaningfully from sharp sportsbook lines—such as the 10% gap seen here between the 45% implied probability and the 55% book-implied probability—it often signals either a lag in market adjustment or a mispricing by retail traders. Comparable cases in recent MLB seasons show that when public betting heavily favours one side (81% of money on the Yankees here) but the line remains stable, sharp money is likely backing the underdog, yet the market has not yet fully corrected[5]. This pattern suggests the 45% figure may be inflated relative to the true win probability.

Traders should monitor starting pitcher announcements and any late-injury updates before the 7:05pm ET start, as these are the primary catalysts for line movement. Doc Sports notes the total is set at 8 runs with pitchers Josh Schonwald and an unnamed Yankees starter taking the mound, and any change to these lineups could shift the odds significantly[3]. With the Yankees’ strong home record (22-15) and the Tigers’ poor away form (12-28), the catalysts remain tightly linked to roster integrity rather than external factors[2].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
