CSyD Macará and Club Alianza Atlético will contest a Copa Sudamericana fixture on 21 May at 22:00 ET. The market currently prices the "More Markets" outcome at 31% implied probability, reflecting how Polymarket's order book has weighted this particular settlement condition across available liquidity. The settlement window closes 22 May at 02:00 UTC, allowing roughly four hours post-match for final trades before resolution.
Copa Sudamericana matches involving Ecuadorian and Peruvian clubs typically generate moderate trading volume on prediction markets, with outcomes sensitive to team form, injury status, and recent domestic league performance. Historical precedent suggests markets on South American club competitions settle with reasonable accuracy when liquidity concentrates in the final 24 hours before kick-off. Current probability of 31% reflects either a perceived disadvantage for one side or genuine uncertainty about match conditions; comparable fixtures between mid-table sides from these nations have shown wide probability ranges depending on home-field advantage and recent results.
Traders should monitor official team news through 21 May for squad confirmations, particularly regarding key players or late injuries. Copa Sudamericana fixtures occasionally experience scheduling changes or postponements due to weather or administrative issues in the region, though no such disruptions have been announced. The settlement mechanism will depend on how the market's terms define "More Markets"—clarification on whether this references additional betting markets, match outcomes, or other derivatives should be verified against the full market documentation before position-taking.
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 "CSyD Macará vs. Club Alianza Atlético - More Markets" 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 $4K 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 22 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.
