Market outcomes
| CA Boston River | 0% YES | 100% NO |

On Thursday, 7 May 2026, Uruguayan side CA Boston River will face Colombian club Millonarios FC in a Copa Sudamericana fixture. The 0% implied probability on Polymarket's order book reflects a market where no traders have yet committed capital to a YES position, suggesting either genuine uncertainty about match occurrence or insufficient liquidity to establish a meaningful price. The settlement window closes at 22:00 UTC that evening, giving traders a narrow window to react to pre-match developments.
Boston River competes in Uruguay's Primera División, whilst Millonarios operates in Colombia's top flight. Historically, Colombian clubs have held a slight edge in continental competitions, though Copa Sudamericana draws regularly feature lower-ranked sides and unpredictable results. The current zero probability should be read as an absence of market activity rather than a consensus forecast—typical for niche sports markets with limited trading volume before fixture confirmation and team news materialises.
Traders should monitor official Copa Sudamericana fixture announcements, team injury reports, and any fixture postponements due to domestic league scheduling conflicts. Colombian football has experienced fixture congestion in recent seasons, and Millonarios' domestic commitments may affect squad availability. Confirmation of the match date and venue, typically released by CONMEBOL weeks in advance, will likely trigger initial order book activity. Weather conditions in Montevideo on match day and late-breaking team news closer to kickoff represent the primary catalysts for probability movement.
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 "CA Boston River vs. Millonarios FC" 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.
$138K in lifetime turnover and $0 of resting liquidity puts this market in the top 30% 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 around 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.

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.
