The Dubai Duty Free Tennis Championships final on Saturday, February 28, 2026, concluded in an unexpected manner as Daniil Medvedev was awarded the title after Tallon Griekspoor withdrew due to a left hamstring injury. The outcome sparked significant interest on prediction markets like Polymarket, where traders had been actively wagering on the match’s potential results. The trading volume for the “Dubai Tennis Championships: Daniil Medvedev vs Tallon Griekspoor” market reached $1 million since its launch on February 28, 2026, demonstrating substantial engagement from the Polymarket community.
Griekspoor sustained the injury during his semi-final victory over Andrey Rublev on Friday, landing awkwardly after a serve. Despite completing the match, scans revealed a serious hamstring issue, preventing him from competing in the final. Medvedev, who was seeking his 23rd tour-level title and his second of the 2026 season after winning in Brisbane in January, claimed the championship by walkover. This marks the first time the 30-year-old has won the same event twice, having previously triumphed in Dubai in 2023.
