Rules
This market will resolve "Yes" if Carlos Alcaraz competes in at least one main-draw singles match at the 2026 US Open, scheduled for August 30, 2026 to September 13, 2026.
- Otherwise, this market will resolve "No."
- Carlos Alcaraz is considered to have "played" if he takes the court and play begins in any of his main-draw singles matches.
- Being entered in the draw, or an opponent's retirement or walkover before any play begins, does not by itself count as having played.
- If Alcaraz begins a match and then retires or is defaulted, this market will resolve "Yes."
- If the tournament is postponed beyond September 27, 2026, 11:59 PM ET, or canceled before Alcaraz plays a main-draw singles match, this market will resolve "No."
