Resolution criteria on PolyGram: More markets for the Copa do Brasil game, scheduled for May 13 at 6:30 PM ET.

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.

Coritiba and Santos will meet in the Copa do Brasil on 13 May at 6:30 PM ET. The current order book on Polymarket prices the YES outcome at 16%, reflecting a substantial underdog position for whichever team this market designates as the favoured side. The settlement window closes at 22:30 UTC that evening, allowing roughly four hours post-match for resolution.
Copa do Brasil knockout fixtures between clubs of this calibre historically show wide probability ranges depending on recent league form and injury status. Santos, a traditional powerhouse with multiple Libertadores titles, typically commands shorter odds in domestic cup play, whilst Coritiba—a mid-table Série A side—faces longer odds in direct matchups. The 16% implied probability suggests the market is pricing in a significant structural disadvantage for one team, consistent with historical disparities in squad depth and recent performance trajectories between these clubs.
Traders should monitor team news through to kick-off, particularly injury confirmations and any late tactical shifts. Recent Série A standings and cup performance records will inform whether the current pricing reflects actual form or outdated seeding assumptions. The tight settlement window means live-match developments will have minimal time to influence late trading, making pre-match information asymmetries particularly valuable. Any official lineup announcements or managerial statements released in the 24 hours before kick-off could shift the order book materially from today's 16% level.

The mechanics for trading "Coritiba FBC vs. Santos FC - More Markets" are the same as any other PolyGram sporting event contract.

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.
