Detroit Tigers vs. San Francisco Giants

Platform comparison

Market context

The Detroit Tigers are visiting the San Francisco Giants in a regular-season MLB game, and this market pays out on which club wins outright; in prediction-market terms, a **YES** share means the named team wins, while a **NO** share means it does not. Because the market can also resolve 50-50 if the game is cancelled without a make-up or ends tied, the main job for traders is to judge the likely final result rather than the margin of victory.[2][11]

A current crowd-implied probability of **56% YES** sits close to the broader betting market, where Detroit has generally been priced as a modest favourite and model-based win chances have ranged from the mid-50s to around 60%. That is consistent with a game that is not a coin flip, but also not a heavy mismatch: recent odds screens have shown Detroit around -127 to -136 and San Francisco around +113 to +125, with several prediction models landing near a 56-60% Tigers win chance.[2][6][11][12] For a newcomer, that means the market is saying Detroit is somewhat more likely to win, but the edge is limited enough that late information can matter.

The main catalysts are the confirmed line-ups, starting pitchers, weather, and any schedule changes, because postponement keeps the market open until the game is completed. The listed first pitch is 10:15 PM ET, so traders will be watching pre-game injury news, any late scratch of a starter, and whether the game starts on time; if it is postponed, the settlement simply waits for the make-up game, while a cancellation or tie would force the 50-50 fallback.[11][17]

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Market UK, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
