The ATP Vienna Winner contract is a sports market on Kalshi tied to the 2026 ATP Vienna professional tennis tournament. Its basic rule is that if a named participant wins the tournament, the market resolves to Yes [1]. The contract is listed under the Sports category and was active at the time of the saved provider observation [1]. The contract also covers withdrawals. If a participant forfeits, withdraws from consideration, or takes an official action that removes them from being able to win the tournament, the market for that participant resolves to No [1]. A participant's market therefore does not depend only on the match results they play. Their status in the tournament can settle the contract. The market closes and expires after a winner is declared [1]. The saved provider record does not supply a listed end time for the event [1]. The individual market rows in the saved snapshot show an end date of 5 December 2026 at 09:00 UTC [1]. That date appears in the contract data, but it is not an announced tournament date or a confirmed resolution date. The contract's own rule states that closing follows the declaration of a winner, so the resolution timing depends on when that event occurs. The saved snapshot was observed at 00:00:05 UTC on 26 October 2026 and retrieved at 00:31 UTC the same day [1]. Those times describe when the provider data was captured. They do not show when the contract closes or resolves. Each price in the snapshot reflects that observation time only. The snapshot shows Yes and No prices for each named participant. For example, one market shows a Yes price of 0.47 and a No price of 0.53 for Adrian Mannarino [1]. Another shows Carlos Alcaraz at 0.23 Yes and 0.77 No [1]. These are recorded prices from one provider snapshot. They are not executable quotes, and they are not verified probabilities of any outcome. The market sample is partial. The saved Kalshi event contains 32 markets, and 12 are included in this sample [1]. The included markets were chosen by highest finite Yes price, with volume used as a tiebreaker, so the omitted 20 markets are not shown and should not be read as having lower prices. The sample describes only this saved provider event and should not be combined with rankings from other events or providers.

Historical Context

The supplied Wikipedia pages describe the wider tennis calendar rather than the Vienna tournament itself. The 2026 ATP Tour is described as the global elite men's professional tennis circuit organized by the Association of Tennis Professionals, and its calendar includes Grand Slam tournaments, the ATP Finals, Masters 1000 events, ATP 500 and ATP 250 events, and the United Cup [3]. The 2026 ATP Finals page describes a planned season-ending event scheduled for 15 to 22 November 2026 in Turin, Italy [2]. These pages provide season context only. They do not report Vienna results, and they do not confirm current tournament status.
