Resolution criteria on PolyGram: This event is for the upcoming Brazil Série A game, scheduled for Saturday, May 30, 2026 between EC Bahia and Botafogo FR.
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.
Market outcomes
| EC Bahia | 46% YES | 54% NO |
| Draw (EC Bahia vs. Botafogo FR) | 46% YES | 55% NO |
| Botafogo FR | 45% YES | 55% NO |
EC Bahia will face Botafogo FR in a Série A fixture on Saturday, 30 May 2026. The current order book on Polymarket prices a YES outcome (Bahia victory) at 47%, reflecting near-parity between the two sides with a slight lean towards a draw or Botafogo win. Settlement occurs at 20:30 UTC on match day.
Bahia's home record and recent form provide historical context for the probability. Over the past two seasons, Bahia has won approximately 35–40% of home matches in Série A, whilst Botafogo has maintained a comparable away conversion rate. The 47% YES price aligns with these empirical win rates, suggesting the market is pricing in Bahia's marginal home advantage without overweighting it. Botafogo's recent investment in squad depth and tactical consistency has narrowed the traditional gap between established Rio clubs and regional sides.
Traders should monitor team news through late May, particularly injury reports affecting key players in either midfield or attack. Fixture congestion in the weeks preceding 30 May—whether either side faces Copa do Brasil or continental commitments—could influence squad rotation and fatigue levels. Weather conditions in Salvador on match day, including heat and humidity, historically favour sides with deeper benches and superior conditioning. Official team sheets typically release 24 hours before kick-off; any last-minute absences could shift the probability materially. Current Polymarket liquidity and order-book depth will determine execution costs for position adjustments as new information emerges.
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 "EC Bahia vs. Botafogo FR" 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.

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.
