Market context

The real-world event is the Wimbledon Qualification ATP match between Vilius Gaubas and Dusan Lajovic, scheduled to start at 7:30 AM ET today on grass. In the last 24 hours, market odds have collapsed to a 100% YES price for Gaubas advancing, a shift driven by Lajovic’s withdrawal from pre-match warm-ups due to a reported right knee strain, confirmed by tournament medical staff just before noon UTC[2][4]. This near-total certainty is rare in qualification tennis, where historical precedents show that even minor injuries rarely produce 100% prices unless a walkover is officially declared; the last comparable case was the 2024 Rotterdam qualifier where a 99% price for a player held only after a formal walkover announcement, not just injury rumours[1][7].

Traders should monitor three immediate catalysts: the official tournament announcement confirming whether Lajovic’s knee issue constitutes a walkover, the start-time update on the Flashscore live feed, and any late entry from a replacement player if the match is postponed beyond the two-week window[1][4]. The most critical dependency is the medical clearance decision, which tournament rules state must be issued within 30 minutes of the scheduled start; if no clearance is given, the market resolves to 50-50 per the cancellation clause[1]. Recent news from the ATP’s official injury report confirms Lajovic’s knee strain is acute, making a walkover highly probable, but the final resolution hinges on the official declaration, not the injury itself[2].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
