Market outcomes

| Completed Match | 50% YES | 51% NO |
The Tunis doubles tournament will feature a match between the pairing of Pokorny and Poljak against Blanch and Hernandez, originally scheduled for 14 May 2026. The current order book on Polymarket reflects a 50-50 split in implied probability, suggesting traders view both teams as evenly matched on available information. Settlement occurs on 21 May, providing a seven-day window for the match to conclude; any cancellation, tie, or delay beyond that threshold triggers a 50-50 resolution regardless of eventual outcome.
Doubles tennis markets at lower-tier events like Tunis often trade at even odds when player pairings lack extensive head-to-head history or recent form data. Poljak and Pokorny's combined ranking strength relative to Blanch and Hernandez will determine whether the current probability holds; similarly positioned pairings at comparable ATP Challenger events have typically resolved within 5-10 percentage points of opening odds when no late-breaking injury news emerges. The absence of significant pre-match volatility suggests limited public information asymmetry between the two teams.
Traders should monitor official ATP communications regarding player withdrawals or schedule changes in the week preceding 14 May, as doubles draws frequently experience last-minute adjustments. Court surface conditions at the Tunis venue and any recent tournament results from either pairing will provide concrete form indicators. The settlement window's seven-day buffer mitigates cancellation risk, though weather delays remain a consideration for North African spring tournaments.
Traditionally, tennis is played between two people in a singles match, or two pairs in a doubles match. Tennis can also be played on different courts, including grass courts, clay courts, hard courts, and artificial grass courts.
