CA Grau vs. CD Comerciantes Unidos

Platform comparison

Market context

CA Grau host CD Comerciantes Unidos in Peru Liga 1 on Friday, 14 August, and Polymarket is pricing this contract at 100% YES, so the market is effectively treating settlement as certain. The contract resolves on the result of the match within 90 minutes plus stoppage time, with the prize only for the specified outcome and no extra-time dependency; on Polymarket, that exposure sits in USDC-backed conditional tokens on Polygon, which is what users are actually holding and trading rather than the fixture itself.

A 100% print usually reflects either a near-locked settlement state or a book that has thinned out completely, so comparable football markets at this level tend to move sharply only when the underlying event is already decided or the official schedule is effectively finalised. In other words, the useful read is not “who should win”, but whether the market has already absorbed the relevant match listing, kick-off time, and oracle resolution path.

For traders, the key catalysts are administrative rather than tactical: a last-minute postponement, venue change, abandoned match, or an official rescheduling would matter more than team news at this stage. The fixture is listed for 20:00 UTC at Estadio Campeones del 36/Estadio Municipal Ambrosio Maco Arroyo in Piura, so the practical watchlist is the federation schedule, the live match status, and any announcement affecting whether the game is completed inside the settlement window.

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 PolyGram, 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.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
