San Francisco Giants vs. Miami Marlins

Market context

Polymarket’s contract is pinned at **0% YES** on the Giants side, which means the on-chain price on Polygon is effectively saying San Francisco’s win is not being assigned any meaningful probability in USDC terms right now. Because settlement depends on the official final result, the market still turns on the game outcome rather than the trading timestamp, and the conditional token only resolves once the MLB result is final or, if applicable, falls into the market’s postponed/cancelled logic.

That zero print sits well outside the sort of pre-game pricing seen in conventional markets, where the Giants were installed as clear favourites on the moneyline. Action Network listed San Francisco at **-144** and Miami at **+122**, while ESPN’s team stats page showed the Giants with a stronger batting line than Miami in batting average, runs, hits and home runs, though the Marlins had the better on-base percentage and slugging percentage on the season snapshot shown. In practical prediction-market terms, this is the sort of setup that often moves sharply if liquidity is thin: a price can stay anchored near zero until late attention, then re-rate fast once traders engage the USDC pool on Polygon.

The main catalysts are straightforward: line-up confirmation, any late pitching change, weather or delay risk, and whether the game is completed as scheduled before the settlement window closes. The market description makes postponement especially important, because an unfinished game keeps the contract open rather than forcing resolution, while a cancellation or tie would push it to a 50-50 outcome. Recent preview coverage from Action Network framed the game as a low-scoring spot, with an **under 8** lean, so traders watching this contract will mostly care about whether the expected run environment holds and whether any announcement changes the starting pitcher or game state before first pitch.[1]

Methodology

We track San Francisco Giants vs. Miami Marlins on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.
