Market context
Aleksandar Vukic faces Alexis Galarneau in the Granby Challenger quarterfinal, a match originally scheduled for 17 July that has seen early momentum favour the Australian. Live score data indicates Galarneau took the first set 3–0, yet the market still assigns a 76% probability to Vukic advancing, suggesting traders expect a significant comeback or that the initial set data reflects a delayed or incomplete feed rather than a decisive lead [1].
Historical patterns in Challenger-level tennis show that 75%+ implied probabilities for a player who has lost the opening set often collapse if the deficit exceeds two sets, yet Vukic’s initial odds of 1.59 versus Galarneau’s 2.18 reflect a strong pre-match favourite status that the market has not fully adjusted for [2]. Comparable cases from recent Granby tournaments reveal that players entering as clear favourites frequently recover from early set losses when their serve dominance remains intact, framing the current 76% as a lagging indicator rather than an overreaction.
Traders should monitor the official tournament schedule for a confirmed restart time, as any delay beyond seven days from the original 17 July date triggers a 50–50 resolution [1]. Key catalysts include Vukic’s serve statistics in the second set and any injury announcements from the Granby venue, with Tennis Tonic noting his projected three-set win as the primary outcome to watch [2]. Absence of a completed match result before the 24 July settlement window will force a neutral resolution, making real-time score updates critical for position management.

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 Prediction Today, 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.
