Resolution criteria on PolyGram: More markets for the Brazil Serie B game, scheduled for May 24 at 3:00 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.

AC Goianiense and São Bernardo FC will contest a Serie B fixture on 24 May 2026 at 3:00 PM ET. The current order book on Polymarket reflects a 36% implied probability for the "More Markets" outcome, suggesting traders are pricing in a moderately low likelihood of additional betting markets materialising around this match. The probability has been formed through active trading on the platform's order book, where the spread between bid and ask prices converges toward consensus.
Historical precedent shows that secondary Brazilian league matches attract variable liquidity and market depth depending on fixture prominence and betting operator interest. Matches involving established clubs or those with playoff implications typically generate broader market coverage, whilst mid-table encounters in less critical periods may see limited derivative markets. AC Goianiense's recent performance trajectory and São Bernardo's standing within the division will influence whether bookmakers and prediction platforms deem the fixture sufficiently high-profile to warrant additional betting options beyond standard outcomes.
Traders should monitor fixture confirmation, team news releases, and any scheduling changes through official CBF (Confederação Brasileira de Futebol) channels in the weeks preceding the match. Injury announcements or managerial changes at either club could shift perceived match significance. Additionally, the broader Serie B calendar and whether this fixture carries playoff or relegation implications will determine operator appetite for expanded market offerings. Settlement occurs at 19:00 UTC on 24 May, providing a defined window for market expansion decisions.
This market settles from the official outcome published at https://www.cbf.com.br/futebol-brasileiro/competicoes/campeonato-brasileiro-serie-b. 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 "AC Goianiense vs. São Bernardo FC - 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.
$0 in lifetime turnover and $2K of resting liquidity puts this market in the below the median 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.
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.cbf.com.br/futebol-brasileiro/competicoes/campeonato-brasileiro-serie-b. 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 24 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.
