| Draw | 53% YES | 48% NO |
| Athletic Club | 36% YES | 64% NO |
SC Internacional will host Athletic Club in a Copa do Brasil fixture on 12 May 2026, with the halftime result market settling on the scoreline at the 45-minute mark. The current order book on Polymarket reflects a 62% implied probability for a home win at the interval, suggesting traders expect Internacional to lead or be level at the break rather than trailing.
Halftime markets in Brazilian domestic cup competitions have historically favoured home sides, particularly when the home team possesses superior possession and pressing intensity in the opening period. Internacional's recent form in the 2025–26 season and their home record at Beira-Rio will inform how traders calibrate expectations. Athletic Club's defensive setup and travel fatigue from away fixtures typically influence first-half dynamics; teams arriving from longer distances often settle into matches more cautiously. The 62% probability sits within the range typical for home advantage in such fixtures, though this depends materially on team selection and recent performance trajectories.
Traders should monitor team news releases up to kickoff, particularly injury confirmations or tactical shifts that might alter pressing patterns in the opening 45 minutes. Weather conditions at Beira-Rio—rainfall can affect passing accuracy and tempo—may shift the probability closer to settlement. The fixture's position within the Copa do Brasil calendar (knockout stage or group phase) affects squad rotation decisions. Recent form announcements from either club's official channels or Brazilian sports media outlets will clarify whether either side enters the match in defensive or aggressive posture, directly influencing halftime outcome likelihood.
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 "SC Internacional vs. Athletic Club - Halftime Result" 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 $3K 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.
