Resolution criteria

Each option in this market will resolve independently based on the total number of Grand Slam (major) singles titles won by Alexander Zverev over the course of his professional career:

• "2 or more" will resolve to YES immediately if Zverev wins his 2nd Grand Slam singles title. If he retires with fewer than 2 titles, it will resolve to NO.

• "3 or more" will resolve to YES immediately if Zverev wins his 3rd Grand Slam singles title. If he retires with fewer than 3 titles, it will resolve to NO.

• "4 or more" will resolve to YES immediately if Zverev wins his 4th Grand Slam singles title. If he retires with fewer than 4 titles, it will resolve to NO.

• "5 or more" will resolve to YES immediately if Zverev wins his 5th Grand Slam singles title. If he retires with fewer than 5 titles, it will resolve to NO.

Definitions and Rules:

• Majors: Only men's singles titles at the Australian Open, French Open (Roland Garros), Wimbledon, and the US Open count. Other achievements, such as the ATP Finals, Olympic medals, or doubles titles, do not count.

• Retirement: Any option that has not been met will resolve to NO once Zverev officially announces his retirement from professional singles tennis, or if he does not play a professional singles match for 3 consecutive years, whichever happens first.

• Source of Truth: Official tournament records or his official player profile on the ATP Tour website.
