Market context
Polymarket’s 0% YES price on this Macará-Santos “more markets” contract means the market is assigning no residual chance that any of the listed settlement conditions still resolve in the affirmative before the 22:00 UTC close on 20 August. The underlying tie was the second leg of a Copa Sudamericana round-of-16 clash at Estadio Bellavista in Ambato, with Santos carrying a 2-1 aggregate lead from the first leg in Brazil[8][9].
That near-zero reading is easier to interpret when set against the match state: by late in the contest, public scoreboards showed Santos ahead on aggregate and the live match still scoreless, which leaves only narrow, event-specific triggers for a “more markets” contract to settle YES[1][6][10]. On-chain, the usual Polymarket mechanics still apply: the position is held through USDC on Polygon and represented by conditional tokens, so traders are really pricing the probability that the specific market condition is satisfied by the deadline, not the broader football result.
For traders, the main catalysts are late official updates: line-ups, substitutions, VAR decisions, added time, and any administrative change to the scheduled kick-off or venue. CONMEBOL’s pre-match notice fixed Bellavista, Ambato, and the 5:00 p.m. Ecuador time start, while broadcaster listings and live match pages confirmed the fixture remained on schedule with no material disruption reported[8][9][12]. In practice, once play is deep into the second leg and the aggregate picture is clear, the contract’s remaining value tends to collapse unless the specific market wording depends on a late goal, extra time, or a discrete match event.

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.
