Pronóstico: National Bank Open: Rafael Jodar vs Arthur Fils

Platform comparison

Market context

Rafael Jodar and Arthur Fils meet again after splitting their first two completed meetings, with Jodar winning on hard courts in Washington in July and Fils coming through on clay in Barcelona in April. The market’s 54% crowd-implied lean towards Fils is broadly in line with the idea that the higher-ranked, more established ATP player should be favoured, but the head-to-head does not offer a clean edge: the pair have already shown that surface and match conditions can swing the result, and the live pricing is only modestly above even money.[1][3][9]

The main read-through for traders is whether the match actually goes ahead as scheduled and whether either player’s draw position changes before first ball. Flashscore’s listing shows the fixture around 10 August, but that does not guarantee it is played on time, and the settlement terms mean a cancellation, no-contest, or a delay beyond seven days would push the market to 50-50 rather than a side result.[5] The key catalyst is therefore official order-of-play and any late withdrawal, because this market is sensitive not just to form but to whether the scheduled matchup survives through to a completed result.[5][6]

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

What are live sports odds on Polymarket?

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
