CA Grau vs. CD Comerciantes Unidos

Platform comparison

Market context

CA Grau’s contract is pricing at 100% YES, which on Polymarket means the market is effectively treating the result as a near-certainty in USDC terms on Polygon, with the conditional token already behaving as if the outcome is locked. For a trader, that leaves very little room for fresh information to reprice the position unless the fixture itself changes or settlement is delayed.

The most useful comparator is not the headline probability but how the contract has historically resolved when the underlying match goes ahead on schedule. Similar Liga 1 markets tend to converge fast once line-ups, venue and kick-off are confirmed, because the on-chain structure only pays out on the specified condition and the price can stay pinned when there is no meaningful schedule risk. ESPN’s fixture listing and match pages showed the game set for Friday 14 August at Atlético Grau’s home venue, which supports the idea that the market is anchored more in event completion than in pre-match uncertainty.[2][7]

What traders still watch is whether the federation, clubs or broadcaster alter the schedule, or whether any administrative issue pushes the match outside the settlement window ending 2026-08-14T20:00:00Z. TV Perú’s published Clausura programme and the live fixture feeds both placed the game on 14 August, and Polymarket’s own market page said postponement would keep the contract open until the game is completed.[5][6][10] That means the main catalyst is not match quality but whether the listed fixture is played in time for settlement, with team news, travel disruption and any official rescheduling the only facts likely to matter at this price.[6][7]

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 UK, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
