Resolution criteria on PolyGram: More markets for the Copa do Brasil game, scheduled for May 13 at 8:30 PM 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. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.

EC Jacuipense will face SE Palmeiras in the Copa do Brasil on 13 May at 8:30 PM ET. The market currently prices the likelihood of additional markets being offered for this fixture at 33 per cent, reflecting modest conviction among traders on Polymarket's order book that supplementary betting options will materialise before settlement on 14 May at 00:30 UTC.
Copa do Brasil matches involving top-tier sides like Palmeiras typically attract expanded market coverage, particularly when fixtures fall within prime betting windows. Historical precedent suggests that Polymarket's market creation responds to both fixture prominence and liquidity demand; matches featuring established Serie A clubs have generally seen multiple derivative markets launched within 48 hours of kickoff. Jacuipense, competing from the lower divisions, represents a less predictable draw for market operators. The current 33 per cent probability reflects uncertainty about whether organisers will deem this pairing sufficiently high-profile to warrant additional betting instruments beyond standard match outcomes.
Traders should monitor Polymarket's market creation activity in the 24 hours preceding kickoff, as this window typically determines whether supplementary markets launch. The fixture's scheduling within the Copa do Brasil's knockout phase and any late team news affecting Palmeiras' squad could influence whether additional markets justify creation costs. Settlement hinges on whether any new markets for this specific match appear on the platform before the 00:30 UTC deadline, regardless of those markets' subsequent resolution.
This market settles from the official outcome published at https://www.cbf.com.br/futebol-brasileiro/competicoes/copa-do-brasil. 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 "EC Jacuipense vs. SE Palmeiras - 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.
$727 in lifetime turnover and $20K of resting liquidity puts this market in the below the median by volume for sports contracts on PolyGram. Order-book depth is modest — expect a couple of cents of slippage on $1k+ trades.
Last 24 hours alone saw $12 in turnover, consistent with the market's lifetime daily-average pace.
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.

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.
