Ceará SC and AC Goianiense will contest a Serie B fixture on 9 May 2026, with settlement determined by the final score after 90 minutes plus stoppage time. The current 0% implied probability on Polymarket's order book reflects the market's assessment that the listed exact-score outcomes carry negligible collective likelihood, with traders pricing the residual probability into the "Any Other Score" category. This positioning is typical for exact-score markets in football, where the combinatorial spread of possible results—ranging from 0–0 through various multi-goal scenarios—fragments probability mass across dozens of discrete outcomes.
Historical Serie B matches between these clubs and comparable fixture data suggest scorelines cluster around narrow margins. Ceará finished the 2024 season in mid-table, whilst Goianiense has shown inconsistent form. The 0% reading on specific outcomes likely reflects sparse liquidity on individual score lines rather than certainty; traders require substantial odds improvement to commit capital to any single exact result when dozens of alternatives remain plausible.
Traders monitoring this market should track team news closer to the fixture date, including injury reports and squad availability, which materially influence scoring patterns. Fixture congestion in the Brazilian calendar and any weather alerts affecting pitch conditions warrant attention. The settlement window closes 22:00 UTC on 9 May, allowing only the standard 90-minute regulation period for resolution; postponements would extend the market's duration but would not alter settlement criteria.
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 "Ceará SC vs. AC Goianiense - 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.
$150 in lifetime turnover and $0 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.
