Londrina EC and São Bernardo FC will meet in a Brazil Serie B fixture on 12 May 2026 at 6:30 PM ET. The market settles on the exact final score after 90 minutes plus stoppage time, with any unmatched scoreline resolving to "Any Other Score." The current order book on Polymarket reflects a 7% implied probability for the specific outcome selected, suggesting traders view it as a relatively unlikely result among the listed possibilities.
Exact-score markets in lower-tier Brazilian football typically show heavily fragmented probabilities across outcomes, given the relative unpredictability of second-division matches and the large number of possible scorelines. Historical Serie B data indicates that draws and narrow victories (1–0, 2–1) account for a substantial share of matches, whilst high-scoring results remain less common. The 7% probability here suggests the market is pricing in either a less frequent scoreline or a less favoured team outcome; comparable exact-score markets for similar-tier fixtures usually see winning probabilities cluster between 5% and 15% for individual outcomes.
Traders should monitor team news, injury reports and recent form in the weeks preceding the match. Londrina and São Bernardo's current league positions, recent goal-scoring patterns and defensive records will influence expected scorelines. Any fixture postponements would extend the settlement window beyond the stated deadline, though the market remains open until completion. Recent fixture congestion in the Brazilian calendar may affect squad rotation and player availability closer to the date.

The mechanics for trading "Londrina EC vs. São Bernardo FC - Exact Score" 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.
