Market context
Polymarket is pricing the Sarmiento v Argentinos Juniors “more markets” contract at a **0% YES** crowd-implied probability, which means traders are effectively assigning no value to whichever side this sub-market requires on Polygon using USDC and conditional tokens. The underlying match in Junín finished **Sarmiento 1-0 Argentinos Juniors** at the Estadio Eva Perón, so the practical issue on the platform is whether the contract’s exact rule was triggered by the final game state rather than the abstract football result.[10][3]
That near-zero pricing sits against a fairly balanced pre-match picture. Polymarket’s own main moneyline reference showed the fixture trading close to a coin flip at **50¢ / 50¢**, while independent preview odds were split between a narrow Argentinos edge and a draw-heavy game, and head-to-head results have been mixed, with each side winning twice in the last seven meetings and three draws.[3][1][12] For a Polymarket user, that kind of baseline matters because “more markets” contracts often hinge on whether the match is low-scoring, one-sided, or decided by a specific margin, so the final 1-0 score can leave many auxiliary outcomes unfulfilled even when the headline result is known.[3][5]
The main catalysts to watch are the settlement rule text, the match record, and any official corrections from the competition or data providers if the market has a contested grading edge case. For traders, the key dependency is whether Polymarket’s conditional token resolves off the full-time result, first-half state, total goals, or another derived condition, because those clauses can diverge sharply from the simple win/lose market and are only settled once the feed and rule set align.[3][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 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.
