Market context
Independiente Medellín faced Vasco da Gama in the Copa Sudamericana at Estadio Atanasio Girardot, with CONMEBOL listing a 19:00 kick-off and the tie level at 1-1 on aggregate before full time.[1] By the time this market settles, the match result itself will already be known, so a 0% crowd-implied YES price is consistent with a market that is effectively asking whether any *additional* qualifying “more markets” condition was triggered after the game state had been resolved.[1][2]
For historical context, this is the kind of market that a power-user would read through the same lens as late-stage in-play volatility: compare the live score, aggregate state, and competition context, then ignore pre-match priors once the event has moved beyond the settlement trigger. Sports Mole’s pre-match model gave Medellín a narrow edge at 46.31%, with the likeliest scoreline 1-0, while live data shows the game finished 2-2 after Medellín led 1-0 at half-time, underlining how quickly football prices can diverge from opening projections when goals arrive late.[3][2]
The practical catalysts to watch are the official match feed, referee and venue confirmations, and any schedule changes that shift the settlement clock, because these determine whether a bot, conditional order, or copy-trade should treat the market as still active or already stale.[1] For programmatic handling, the key dependency is straightforward: reconcile the exchange market timestamp against the competition fixture and live result feed, then suppress any new order logic once the settlement window has passed and the outcome is final.[1][2]
Methodology
This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Kalshi Fees, which mirrors the Polymarket order book directly.
Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
