This market closes at the start of the candidates tournament. If Gukesh, somehow, participates in the tournament and is paired in the first round, but never manages to play a match due to sickness, protest, or other factors, it will resolve negatively. This market will resolve negatively after the first round of the tournament occuring without Gukesh being a listed player, or positively upon Gukesh playing a match in the tournament.
