Detroit Tigers vs. New York Yankees

Platform comparison

Market context

The upcoming MLB contest pits the Detroit Tigers against the New York Yankees at Yankee Stadium on 30 June, with the game scheduled to commence at 7:05 PM ET. This specific prediction market offers an 85% implied probability that the Tigers will secure the win, a figure that stands in stark contrast to the broader sportsbook consensus where the Yankees are heavily favoured.

Historically, such a divergence between a high prediction-market probability and a negative moneyline for the favoured team often signals a sharp mispricing or a unique market sentiment rather than a genuine upset likelihood. In comparable MLB contracts, when sportsbooks list the Yankees at -132 on the moneyline while a prediction market assigns the Tigers an 85% win chance, the sportsbook line usually reflects the true statistical probability, suggesting the prediction market is offering value on the underdog that the odds do not support. The Tigers are currently +109 on the moneyline, and the total is set at 8 runs, indicating the market expects a competitive game despite the Yankees' superior run-line record of 39-44 this season.

Traders must monitor the starting pitcher lineups and any late-injury announcements before the settlement window closes, as these dependencies directly influence the outcome. Recent analysis from Action Network highlights that the Tigers have gone under the total in Tarik Skubal’s last four outings, allowing four runs or fewer, which could be a critical catalyst if the game remains low-scoring. Furthermore, the Yankees’ strong starting option and the Tigers’ defensive trends suggest the under 7.5 runs bet is favoured by some models, adding another layer of complexity to the win probability. The settlement window ends on 7 July 2026, allowing time for any postponed games to be completed, but the immediate focus remains on the starting pitchers and their recent performance trends.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
