Alejandro Tabilo and Dusan Lajovic are scheduled to meet in the Valencia tournament on 15 May 2026. The current order book on Polymarket prices Tabilo's advancement at 75%, reflecting confidence in the Chilean player's form relative to the Serbian competitor. The settlement window closes 22 May 2026, allowing a seven-day buffer for fixture delays or rescheduling before the market resolves to 50-50.
Tabilo has climbed to a career-high ranking in recent seasons, establishing himself as a consistent performer on the ATP circuit with improved results on hard courts. Lajovic, now in his mid-thirties, has experienced a decline in ranking and tournament success compared to his peak years around 2017–2018. Historical matchups between players of differing trajectory phases typically see the ascending player favoured by markets, which aligns with the current 75% probability for Tabilo.
Traders should monitor official Valencia tournament announcements regarding draw confirmation and any scheduling changes, particularly given the early morning start time (4:30 AM ET) which may be subject to adjustment. Injury reports or late withdrawals from either player would trigger immediate repricing. Court surface conditions and recent tournament results from both players in the weeks preceding Valencia will provide concrete data points for reassessing the current probability before the match commences.
