Resolution criteria

This is a market to predict whether Carlos Alcaraz or Jannik Sinner wins more Grand Slam championships in 2026. If Carlos Alcaraz wins more Grand Slams in 2026 than Jannik Sinner, this market will resolve to “Alcaraz”. If Jannik Sinner wins more Grand Slams in 2026 than Carlos Alcaraz, this market will resolve to “Sinner”. If Alcaraz and Sinner win the same amount of Grand Slams in 2026, this market will resolve 50-50. Only victories in Men’s Singles Grand Slam tournaments will be considered for this market’s resolution. The relevant 2026 Grand Slams are the Men’s Singles tournaments in the 2026 Australian Open, French Open, U.S. Open, and Wimbledon. If it becomes impossible for either Alcaraz or Sinner to win as many Grand Slams in 2026 as the other (e.g. Alcaraz wins the first three grand slams), this market will resolve immediately. Otherwise, this market will resolve when the results of the final 2026 Grand Slam are official. The primary resolution source for this market will be information from the organizers of the Grand Slam tournaments; however, a consensus of credible reporting may also be used.

ⓘ A market settles under its own written rules, which can lag what looks decided in the news — so the price may not move to 100% the moment an outcome seems obvious.
