Counts every singles match Zverev wins at the 2026 Nitto ATP Finals (Turin, Nov 15–22): up to three round-robin matches, plus the semifinal and final if he reaches them. Five wins means an undefeated title. A walkover or retirement by his opponent counts as a win; a match Zverev retires from or forfeits counts as a loss. Round-robin wins count even if he fails to advance.

Each answer resolves independently: "At least N" is YES if his total is N or more, NO otherwise. Rungs resolve as soon as they are decided. If Zverev withdraws before playing his first match, the whole market resolves N/A; if he withdraws after playing at least one match, the count stands.
