Halle Open: Alexander Zverev vs Raphael Collignon

Platform comparison

Active sub-markets

Market context

Polymarket has this contract at **26% YES** today, so the USDC/Polygon price is implying Raphael Collignon is the more likely outcome unless Alexander Zverev advances against him. In practical terms, that means traders are paying for a minority chance that Zverev gets through, with the contract settling on the on-chain conditional token outcome rather than the tennis scoreline itself.

The market sits inside the 2026 Terra Wortmann Open in Halle, which runs from 15 to 21 June on the ATP Tour grass calendar.[1][3] Zverev already won his previous Halle match on Thursday, beating an opponent 6-3 7-6(4), which underlines that he is already deep into the week and still active in the draw.[2] Grass-court events can reprice quickly when draws open up, when a seed advances unexpectedly, or when a player’s fitness becomes clearer between rounds.

A trader will want to watch the official Halle schedule and ATP result feed for timing changes, because this contract only resolves to 50-50 if the match is not played, ends level, or is delayed beyond seven days without a winner.[2][3] Any late withdrawal, medical timeout that turns into a walkover, or a rescheduled start would matter more here than headline form, since the final Polymarket payout follows the contract rules on advance/not advance rather than tournament narrative.
