This market will resolve to 'Yannick Hanfmann' if Yannick Hanfmann advances against Jan-Lennard Struff. This market will resolve to 'Jan-Lennard Struff' if Jan-Lennard Struff advances against Yannick Hanfmann. If the match is canceled (not played at all), ends in a tie, or a winner has not been determined by November 10, 2026, 11:59 PM ET (14 days after the scheduled start), this market will resolve to 50-50.

What the contract measures

This Polymarket event covers the tennis match between Yannick Hanfmann and Jan-Lennard Struff at the Swiss Indoors Basel, which the provider lists as originally scheduled for October 27, 2026 at 5:00AM ET [1]. The match winner rule says the market "will resolve to 'Yannick Hanfmann' if Yannick Hanfmann advances against Jan-Lennard Struff," and the reverse for Struff [1]. It resolves 50-50 if the match is canceled, ends in a tie, or has no determined winner by November 10, 2026, 11:59 PM ET [1]. If a player advances because the opponent retires, defaults, or is disqualified after the match begins, the market resolves to that player. A walkover resolves 50-50 [1]. The primary resolution source is official ATP Tour information, and a consensus of credible reporting may also be used [1].

Contracts in this sample use different wording. Totals such as "Match Over/Under 21.5" and "Set 1 Games Over/Under 8.5" ask about different thresholds, so their prices answer different questions. Every included market lists an end time of 2026-11-03T09:00:00.000Z [1]. That is a listed close field, not an announced resolution date.

Reading the snapshot

The provider observed these prices at 2026-10-27T09:00:05.939Z, and the source was retrieved at 2026-10-27T09:12:17.844Z [1]. These figures are snapshots, not executable quotes or verified probabilities.

Within the included markets, the Set 1 Winner contract priced Hanfmann at 0.485 and Struff at 0.515. The Set 2 Winner contract priced Hanfmann at 0.475 and Struff at 0.525 [1]. The Completed Match contract priced Yes and No at 0.50 each [1]. The Match Over/Under 21.5 contract priced Over at 0.62 and Under at 0.38, while the 22.5 line priced Over at 0.59 and Under at 0.41 [1]. Because these lines have different thresholds, they should not be compared as the same question.

The sample is partial. Polymarket has 16 markets for this event, and 12 are included [1]. Markets were selected by highest finite Yes price, then volume. The four omitted markets are not shown, so no conclusion should be drawn about their prices. Volume is not reported as a measure of liquidity or trader count. Only one provider event is included, so no cross-platform comparison is made.

What remains uncertain

The evidence does not explain why prices sit where they do, and it contains no match result, live score, or news about the match. It does not show whether the match has been played, delayed, or canceled since the snapshot. Price differences between contracts do not by themselves indicate an arbitrage opportunity, because thresholds, resolution wording, and close times can differ. Anyone relying on this information should check the current provider page and the official ATP source.

If the match is played to completion, this market will resolve to "Over" if the total number of sets played equals or exceeds 3, and to "Under" otherwise. A set counts as played once it has begun, even if it is not played to completion. A super tie breaker is considered as one (1) set.
If the match is postponed or suspended, this market will remain open until the match has been completed. A postponement alone will not trigger a 50-50 resolution.
If a player retires, withdraws, is defaulted, or is disqualified, or the match otherwise begins but is not completed, this market will resolve based on any outcome that was already unequivocally determined at the time play stopped. An outcome is considered unequivocally determined if it would have been guaranteed under every possible completion of the match played according to the match format published by the tournament organizer for that round. For example, for a line of 2.5, if play stops with the players at one set each, completing the match would have required at leas

This market will resolve to "Over" if the total number of games completed equals or exceeds 23. Otherwise, it will resolve to "Under." All tiebreaks, including any Champions/Super tiebreak, count as one (1) game.
If the match is postponed or suspended, this market will remain open until the match has been completed. A postponement alone will not trigger a 50-50 resolution.
If the match is permanently abandoned before completion, or if the match has not been completed by November 10, 2026, 11:59 PM ET, this market will resolve 50-50, unless the outcome has already been unconditionally determined based on completed play. An outcome is considered unconditionally determined if it would have been guaranteed under every possible completion of the match played according to the match format published by the tournament organizer for that round, including whether a final set is played as a full set or as a match tiebreak. For example, for a line of 21.5, if play stops at 6-3, 5-6, completing the match would have required at

Overview

This PredictPedia entry covers a prediction market on the men's singles match between Yannick Hanfmann and Jan-Lennard Struff at the Swiss Indoors Basel tournament. The tournament is described as a men's tennis event on indoor hardcourts, the 55th edition of the event, and part of the ATP 500 tournaments of the 2026 ATP Tour, held at the St. Jakobshalle in Basel from 26 October to 1 November 2026 [2]. The market's listed match was originally scheduled for October 27, 2026 at 5:00AM ET [1]. The main contract on this event asks which player advances. It resolves to Yannick Hanfmann if he advances against Jan-Lennard Struff, and to Jan-Lennard Struff if Struff advances against Hanfmann [1]. The rules set out several exceptions. If the match is canceled, ends in a tie, or has no determined winner by November 10, 2026, 11:59 PM ET, which is 14 days after the scheduled start, the market resolves 50-50. If a match begins but is not completed because one player retires, defaults, or is disqualified, the market resolves to the player who advances. A walkover, where a player withdraws before the start and the other advances automatically, also resolves 50-50 [1]. The stated primary resolution source is official information from the ATP Tour, and a consensus of credible reporting may also be used [1]. The listed end time for the event is 2026-11-03 09:00 UTC [1]. This end time is the listed provider time and should not be read as the date the match is expected to finish. Several other contracts on the same event are titled around match totals, set game totals, set winners, and a game spread. Their titles describe what each contract tracks, but this entry does not explain their full rules.

Historical Context

The Swiss Indoors Basel is described as the 55th edition of the event, which indicates a long-running tournament series [2]. Struff's career-high singles ranking of world No. 21 is dated to 19 June 2023 in the supplied source [3]. The tournament's 2026 edition is described in the supplied source as a future event, so the background here concerns the event series and the player's ranking history rather than the match outcome.

Why It Matters

The contract measures which of two named players advances in a single scheduled tennis match. Its wording turns a match result into a yes or no style outcome for each player, with specified treatments for cancellations, retirements, and walkovers [1]. Because the rules define what happens in those situations, the contract's meaning depends on the resolution language rather than on the match name alone [1]. The displayed prices are provider snapshots, not executable quotes or verified probabilities. A snapshot shows the price at a moment in time and does not show whether the contract can be traded at that price. The primary resolution source is the ATP Tour, so the official tour information is the reference point for how the contract is meant to settle [1].

Snapshot context

The latest published provider snapshot for this topic was observed on 2026-10-27 at 09:00 UTC. It contains listings from Polymarket. Market descriptions and listed closing times define the contracts; they do not establish that the real-world outcome has occurred. This article does not include a separately verified news update.
