The Minnesota Twins face the Cleveland Guardians in an MLB regular season matchup scheduled for 8 May at 7:15 PM ET. The settlement window extends to 15 May, allowing for postponements. Current order book depth on Polymarket shows a 0% implied probability for a Twins victory, indicating either extreme confidence in a Guardians win or minimal liquidity positioning at present price levels. This represents an unusual market state for a major league fixture between competitive division rivals.
The AL Central has shown volatility in recent seasons, with both franchises capable of sustained runs. The Guardians reached the World Series in 2023, whilst the Twins have maintained competitive rosters. Historical matchups between these teams typically settle with probabilities reflecting relative strength, recent form, and home-field advantage. A 0% reading suggests either the market has collapsed to one side due to thin order book conditions, or material information regarding roster availability has shifted expectations dramatically.
Traders should monitor roster announcements through to game time, particularly injury status of key position players or pitchers. Starting pitcher assignments, typically confirmed 24–48 hours before first pitch, will influence probability movements substantially. Weather conditions at the scheduled venue may also trigger postponement considerations. Recent Cleveland and Minnesota performance metrics, including run differential and bullpen availability, will provide calibration points as liquidity potentially deepens in the order book approaching game day.
This market settles from the official outcome published at https://www.mlb.com/. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.
The mechanics for trading "Minnesota Twins vs. Cleveland Guardians" are the same as any other PolyGram sporting event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$575K in lifetime turnover and $0 of resting liquidity puts this market in the top 2% by volume for sports contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
Last 24 hours alone saw $573K in turnover, well above the lifetime daily-average for this market — a clear sign of news catalysing trader activity right now.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
Resolution is sourced from https://www.mlb.com/. Settlement is executed by the UMA optimistic oracle on Polygon, with a 2-hour dispute window before payouts clear.
This prediction market is scheduled to close on 15 May 2026. After the resolving event occurs, settlement typically clears within 24 hours once the UMA optimistic oracle confirms the outcome. All payouts are in USDC on the Polygon network.

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
