Club Nacional de Football vs. CA Boston River

Platform comparison

Market context

Club Nacional de Football were at home to CA Boston River in the Uruguayan Primera División, with the match already scheduled for Gran Parque Central and the market now effectively pricing the result as settled. The crowd-implied **0% YES** reading is consistent with the fact that the game is complete and the scoreline ended **1-2** in Boston River’s favour, so a programme consuming this market via API or conditional rules would treat it as a closed event rather than a live probability signal[1][2][3].

Historically, this fixture usually leans towards Nacional, which matters when reading any pre-match or suspended price feed: across recent head-to-head data, Nacional have won the majority of meetings and Boston River have rarely taken points away from them[12][16][18]. Before kick-off, a trader would typically weight the market against that long-run bias, then model whether the home edge at Gran Parque Central is strong enough to justify short-dated conditional orders or copy-traded exposure; in this case, the realised 1-2 result shows the favourite profile did not hold[1][5][20].

For live or programmatic monitoring, the main catalysts were the official team sheets, kickoff confirmation, and any late schedule changes, because those are the points at which a bot or automated dashboard would reconcile exchange price with match status. Boston River’s scoring form and Nacional’s recent goals profile were both relevant context, but the decisive dependency was simply whether the event stayed on schedule and reached full time, which it did[2][12]. Media and fixture feeds also confirmed the same venue and start time, reducing ambiguity for order placement and settlement logic[2][4].

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.
