Resolution criteria

This market will resolve to "Yes" for each men's tennis player who reaches the semifinals (Top 4) of the 2025 US Open in the Men's Singles event. Official results will be verified through the US Open's official website and reputable sports news outlets.

Background

The 2025 US Open is scheduled from August 24 to September 7, marking the first time the tournament will span 15 days, starting on a Sunday. This expansion allows the first round to be played over three days, potentially affecting player scheduling and recovery times. (reuters.com)

As of July 2025, the ATP rankings are as follows:

1. Jannik Sinner (Italy) – 12,030 points

2. Carlos Alcaraz (Spain) – 8,600 points

3. Alexander Zverev (Germany)

6. Novak Djokovic (Serbia)

Notably, Jannik Sinner recently secured his position as world No. 1 after winning Wimbledon 2025 against Carlos Alcaraz. (as.com)

Considerations

The expanded 15-day format of the 2025 US Open may influence player performance due to altered scheduling and potential changes in recovery periods. Additionally, the proximity of the US Open to other major tournaments, such as the Masters 1000 events in Toronto and Cincinnati, could impact player participation and form leading into the Grand Slam.

Only the top seeds have been added, considering that only 4 players will make the semifinals. If anyone would like to request more players to be added, please do so by pinging me in the comments.
