Resolution criteria on PolyGram: More markets for the Brazil Série A game, scheduled for May 17 at 10:00 AM ET.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution.

Santos and Coritiba will meet in Brazil's top division on 17 May 2026 at 10:00 AM ET. The current order book on Polymarket reflects a 27% probability for the "More Markets" outcome, suggesting traders are pricing in a relatively low likelihood of this specific settlement condition being triggered. This probability has formed through live trading activity on the platform's order book, where the spread between bid and ask prices converges toward an equilibrium price that incorporates available information about the fixture.
Historical context for Série A matches between mid-table and lower-ranked sides shows that secondary market conditions—such as injury announcements, tactical shifts, or late-season positioning stakes—often drive significant repricing in the final week before kickoff. Santos has competed in the top flight consistently, whilst Coritiba's recent seasons have seen variable performance. The 27% mark suggests traders currently view the triggering event as unlikely relative to baseline expectations, though this can shift materially if either club announces squad changes or if their league standings shift the stakes of the match.
Traders should monitor official team news releases and Série A fixture confirmations through mid-May. Injury updates, managerial statements, and any changes to the scheduled kick-off time could alter the probability substantially. The settlement window closes at 14:00 UTC on match day, providing a narrow window for final information incorporation before the market locks.
This market settles from the official outcome published at https://www.cbf.com.br/futebol-brasileiro/competicoes/campeonato-brasileiro-serie-a. 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 "Santos FC vs. Coritiba FBC - More Markets" 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.

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.
