Granby: Daniel Milavsky vs Duncan Chan

Platform comparison

Market context

Daniel Milavsky is set to face Duncan Chan in the Granby Challenger men’s singles match, originally scheduled for 13 July 2026 at 10:00 ET in Canada. The contest remains unplayed as of 15 July, with the market now implying a 100% probability that Milavsky will advance. Tennis Tonic’s pre-match analysis favoured Milavsky as the pick to win in three sets, citing initial odds of 1.50 against Chan’s 2.375, reflecting a clear edge in perceived form and head-to-head potential [1].

Historically, markets assigning 100% implied probability to a single player in Challenger-level tennis have rarely held when matches are delayed beyond the scheduled date, particularly in events with limited player depth. In comparable 2024–2025 Granby and similar North American Challenger delays, outcomes shifted when injuries or scheduling conflicts emerged post-deadline, often triggering 50–50 resolutions if no winner was determined within seven days. The current certainty appears fragile given the match’s postponement and the unresolved status of play.

Traders should monitor official ATP Challenger updates for confirmation of whether the match will be rescheduled within the seven-day window, as well as any injury reports from either player. Tennis Stats notes the match was listed for 9:25 pm on 14 July in Granby, suggesting a possible time-zone discrepancy or delay [2]. A formal announcement from the tournament organiser or a withdrawal notice from either player would be the primary catalyst for a probability shift away from the current 100% YES stance.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

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.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

How fast do sports winnings settle?

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
