Cleveland Guardians vs. Detroit Tigers

Platform comparison

Active sub-markets

Market context

The Cleveland Guardians play the Detroit Tigers in the first game of a scheduled series at Comerica Park on Thursday afternoon. The market is priced at 16% for a Cleveland win, so a programmatic read would treat the Guardians as a clear underdog and focus on whether the line has already adjusted for recent form rather than chasing the raw price. That is sensible here because Cleveland has just taken a recent head-to-head meeting 8-2, with José Ramírez driving the offence, which may be a useful comparator for models that weight short-run matchup data and park effects.

For traders running conditional orders or alert bots, the main inputs are the confirmed starters, any line-up scratches, and whether either club is managing workload after the series opener. Recent results matter because Detroit had been described as “reeling” in the AP-cited game report carried by CBS Sports, while Cleveland’s win showed it could generate extra-base damage against this pitching staff. In a live workflow, the key dependency is the official pre-match line-up release; if either side rests regulars, the implied probability can move quickly before first pitch. Also note the market stays open if the game is postponed and only settles on completion, so automation should account for weather or schedule changes rather than assuming an immediate result.

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

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.
