This market asks which player will hold the official ATP men's singles No. 1 ranking on December 31, 2026. The year-end or end-of-year ranking is a widely watched indicator of season-long performance and consistency on the ATP Tour.
ATP rankings are based on points earned at eligible tournaments over a rolling 52-week period, with the biggest contributions coming from Grand Slams, ATP Masters 1000 events, and the season-ending ATP Finals. Historically, the player who is No. 1 at the close of the calendar year has combined deep runs at major events, consistent results across surfaces, and relative health throughout the season.
Prediction market prices reflect the collective market view about which player will be listed as ATP No. 1 on Dec 31, 2026; they update as match results, injuries, retirements, and rule changes occur. These prices are signals of expectations, not guarantees; always cross-check with official ATP publications and the market's settlement rules.
Settlement will use the ATP's official published men's singles rankings for the relevant date as specified by the contract; check the market's rules page for whether the ranking list dated Dec 31, 2026 or the most recent ATP publication on or before that date is used.
Grand Slam results and ATP Masters 1000 events across the 2026 season, plus the ATP Finals in November 2026, typically have the largest point impacts; performance in those events tends to be decisive for year-end ranking positions.
Potentially yes if that player still holds more ATP ranking points than all others on that date, but prolonged inactivity usually leads to points dropping off after 52 weeks and will normally erode a player's ranking unless protected by specific ATP rules.
Any ATP rule change that affects the official rankings will be reflected in the ATP's published lists; market settlement follows the ATP's official rankings and the exchange's contract terms, so check both sources for how specific changes are handled.
Only tournaments and matches that award ATP ranking points affect the official rankings; exhibitions typically do not. Some team competitions may award points depending on ATP policy for that year—consult the ATP calendar and rulebook for which events carry points.
