Cincinnati Open: Winner

This market will resolve to "Yes" if Novak Djokovic officially announces his retirement from ATP Tour professional tennis by the specified date, 11:59 PM ET. Otherwise, this market will resolve to "No".

To resolve "Yes", the announcement must clearly state that Novak Djokovic is retiring or indefinitely departing from ATP Tour professional tennis with intention of not participating in any event that contributes to an ATP ranking. The announcement must come from Novak Djokovic or official representatives thereof.

Only announcements which are framed as announcing a departure from professional competition intended to be effective within 12 months of the date of the announcement will qualify (e.g., neither "I will leave competition in 2 years," nor "I will not play forever," would qualify).

If Djokovic retires in a qualifying manner but maintains, renews, or announces his intention to participate in the Olympics, that retirement will still qualify. Olympic participation, or participation in a tennis competition which does not contribute to an ATP ranking, will have no bearing on this market.

The primary resolution source for this market will be official statements from the named individual or authorized representatives thereof.

The "year-end ATP singles rankings" are the final official singles rankings published after the conclusion of the 2026 ATP Tour season, including the ATP Finals. 

A player ranked exactly 10th counts as "Yes"; a player ranked 11th or lower, or unranked, counts as "No".

"ATP ranking points" refers to Sinner's total points as shown in his official ATP singles ranking (the rolling 52-week total) in any official weekly ranking update published on or before December 31, 2026. If any single official ranking release during this period shows Sinner with 15,000 or more points, this market resolves "Yes."
