San Francisco Giants vs. Colorado Rockies

Platform comparison

Active sub-markets

Market context

The San Francisco Giants travel to Colorado on 31 May for a day game against the Rockies at 3:10 PM ET. The 70% implied probability favouring the Giants reflects their stronger 2026 roster composition and recent head-to-head record, though both franchises sit in the middle tier of NL West performance. Coors Field's high altitude and thin air traditionally favour hitters, which complicates standard pitching matchup analysis; the Rockies' home-field advantage in run-scoring potential has historically compressed win probabilities in their favour despite weaker overall team metrics.

The Giants' recent form and pitching depth provide the primary catalyst for current market pricing. Colorado's injury status—particularly any absences in their catching or outfield rotation—will shift the book materially in the hours before first pitch. Weather conditions at Coors, including wind direction and temperature, directly influence ball carry distance and scoring pace. Traders depositing via Klarna or SEPA transfers should account for settlement timing: the market closes 2026-06-07 at 19:10 UTC, allowing six days post-game for official MLB statistics to be confirmed. Withdrawal rails remain active throughout the settlement window, though book depth typically thins once the game concludes and resolution becomes administrative rather than speculative.

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

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.
