Market outcomes
| Makarska: Robin Montgomery vs Lea Boskovic | 63% YES | 38% NO |
| Completed Match | 50% YES | 50% NO |
Robin Montgomery and Lea Boskovic are scheduled to face off in a tennis match at Makarska on 3 June 2026. The current order book on Polymarket prices Montgomery's advancement at 62%, reflecting modest confidence in the American player. This probability has formed through real-time trading activity and reflects the collective assessment of participants weighing their respective form, head-to-head records, and surface suitability.
Montgomery, ranked in the mid-100s on the WTA tour, has shown inconsistent results on clay courts, where Makarska tournaments are typically held. Boskovic, a Croatian player competing near home, carries the advantage of familiarity with regional conditions and local support. Historical patterns suggest that clay-court specialists and home-region competitors often outperform their seeding, particularly in smaller European tournaments where surface expertise becomes more decisive. The 62% probability assigned to Montgomery suggests the market is pricing in some uncertainty despite her higher ranking, likely accounting for Boskovic's clay-court experience and home advantage.
Traders should monitor official tournament draws and any late withdrawals, which remain possible until the match begins. Injury announcements or schedule changes could shift the probability materially. The settlement window extends to 10 June, allowing a seven-day buffer for delays, though matches at this level typically proceed as scheduled. Recent form updates from both players' competing tournaments in May 2026 will provide the most concrete data for reassessing the current odds.
