Market context

Polymarket is showing this Houston Astros v Minnesota Twins contract at 0% YES, so the current price effectively implies no live market support for either side on-chain. On Polygon, buyers and sellers are still trading conditional tokens settled in USDC, but at this level the contract is behaving more like a stalled line than a normal two-way game price. For the scheduled 1:40 pm ET first pitch, that leaves any move dependent on fresh participation rather than a gradual shift in sentiment.

The recent results do at least give some context. Minnesota beat Houston 6-3 on Monday at Target Field, with Josh Bell hitting two home runs, and the Twins have taken recent home form against an Astros team that entered that matchup with a poor season record. Earlier betting screens had Houston around -105 and Minnesota around -115, with the total at 9 or 9.5, which suggests bookmakers saw the game as fairly close even before the latest result. In prediction markets, prices can stay pinned at extreme levels when liquidity is thin, so the 0% reading should be treated as a market signal about participation, not a firm view of the baseball odds.

A trader would normally watch for any line-up confirmation, starting pitcher changes, or late weather and schedule adjustments before deciding whether this contract can reprice meaningfully. ESPN’s live game page for Monday’s meeting already reflected Minnesota’s win probability once the game was underway, and the official final result will be the key settlement reference if there is no postponement. If the game is delayed, completed later, or altered by a venue or schedule change, that matters more here than in a standard sportsbook because Polymarket’s conditional tokens only resolve once the designated event is officially completed.

Methodology

We track Houston Astros vs. Minnesota Twins 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.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.
