Nitto ATP Finals: Player to Qualify

This market will resolve "Yes" if the listed player finishes the 2026 season ranked within the top 10 (positions 1 through 10, inclusive) of the official year-end ATP singles rankings. Otherwise, this market will resolve "No".

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".

If the ATP does not publish a year-end singles ranking for 2026, or the season is not completed, this market will resolve to "No".

The primary resolution source will be the official ATP year-end singles rankings published at atptour.com; however, a consensus of credible reporting may also be used.

ATP 2026 End of Year Rankings: Player to Make Top 10

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.

This market will resolve "Yes" if Jannik Sinner's official ATP singles ranking points total reaches or exceeds 15,000 at any point on or before December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve "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."

The points total is measured strictly from the official ATP singles rankings, not the "Race to Turin" standings, live rankings, or any projected or unofficial total.

The primary resolution source will be the official ATP singles rankings published at atptour.com; however, a consensus of credible reporting may also be used.
