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.
