This market resolves based on which player is ranked World No. 1 in men’s singles in the first official ATP ranking published after the completion of the 2026 Rolex Shanghai Masters.

The answer options are:

• Jannik Sinner

• Alexander Zverev

• Someone else

Someone else resolves as the winning option if any player other than Jannik Sinner or Alexander Zverev holds the No. 1 position in that official ATP ranking.

For this market to remain valid, both Jannik Sinner and Alexander Zverev must actually participate in the 2026 Rolex Shanghai Masters.

A player is considered to have participated if he plays at least one official point in a main-draw match at the tournament.

If either Sinner or Zverev does not play at all, even if he was originally entered, included in the draw, or present at the tournament, the market resolves N/A.

If either player starts an official match but subsequently retires, withdraws due to injury, or is disqualified, he will still be considered to have participated and the market remains valid.

Resolution is based exclusively on the first official PIF ATP Rankings published after the completion of the Shanghai Masters. Live rankings, unofficial ranking projections, and Race to Turin standings do not count.

If the Shanghai Masters is delayed or postponed, the market will remain unresolved until the tournament is completed and the subsequent official ATP ranking incorporating its results is published.

If the tournament is cancelled entirely, the market resolves N/A.

The market is intentionally scheduled to close on October 15, 2026 at 20:00 (Europe/Athens), before the decisive final stages of the Shanghai Masters. This allows traders to incorporate much of the tournament’s results while preserving a meaningful forecasting window before the outcome becomes substantially clearer.
