Market context
Instituto de Córdoba’s clash with Gimnasia y Esgrima de Mendoza has already produced a decisive result, with the match finishing 1-0 to Instituto on 8 August, so the contract’s 0% YES level is broadly consistent with a market that is now effectively pricing in a no-hit outcome for the settlement window.[10] In pre-match comparison terms, though, this was not an obvious mismatch: the head-to-head record was tilted towards Gimnasia Mendoza, which had won three of the prior four meetings and drawn one, while the only 2026 meeting before kick-off ended 1-0 to Gimnasia Mendoza.[1][2] That makes the prediction-market price look far tighter against historical precedent than a simple one-off team-strength read would suggest, especially in a fixture where recent scores have tended to be low and narrow.[2][8]
For traders comparing platforms, the main point is that prediction markets, sportsbook-grade match pages and analyst-style H2H models were all pointing to a constrained game rather than a runaway scoring pattern, but they were not aligned on which side had the edge.[2][5][11] Sportradar’s match stats profile showed Gimnasia Mendoza games averaging only about two goals, with both teams scoring in just 33% of the sampled matches, which supports a low-variance read on the contest.[5] Fox Sports’ game boxscore listed Instituto’s leading scorers and match card as a standard league fixture rather than a special-circumstances event, so the main catalysts were lineup confirmation, late injuries and any schedule-related rotation, not external conditions.[4][9] The settlement window ending shortly after kick-off means the contract is likely to be driven entirely by the confirmed result rather than in-play momentum.[10]
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
- 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 fast are USDC deposits?
- Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.
- 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.
