São Paulo FC will face CA Boston River in the Copa Sudamericana on 26 May 2026, with the match kicking off at 6:00 PM ET. The market resolves on the exact final score after 90 minutes plus stoppage time, excluding extra time and penalties. Any outcome not explicitly listed settles as "Any Other Score." The current 49% YES probability on Polymarket's order book reflects substantial uncertainty around whether the match will produce one of the pre-specified scorelines rather than an alternative result.
Exact-score markets in Copa Sudamericana fixtures typically show dispersed probabilities across multiple outcomes, given the tournament's competitive depth and unpredictability. Historical data from similar South American club competitions suggests that roughly 35–45% of matches conclude with scores outside the top five most common results, which contextualises why "Any Other Score" commands meaningful backing. The 49% probability for the YES outcome indicates traders are pricing in moderate confidence that one specific scoreline will materialise, though the fragmentation across possible results remains substantial.
Key variables affecting settlement include team lineups, which may shift due to injury or continental fixture congestion in the weeks preceding the match. São Paulo's domestic league commitments and Boston River's preparation schedule will influence squad availability. Weather conditions in the venue and any late fixture rescheduling could also impact match dynamics. Traders should monitor official Copa Sudamericana communications and both clubs' injury bulletins as the settlement window approaches, particularly any announcements affecting squad depth or tactical approach.
This market settles from the official outcome published at https://www.conmebol.com/sudamericana/. 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 "São Paulo FC vs. CA Boston River - 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 $442 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.conmebol.com/sudamericana/. 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 26 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.

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.
