Winston-Salem Open: Raphael Collignon vs Rinky Hijikata

Platform comparison

Market context

Polymarket is pricing this contract at 0% YES, which means the market currently assigns no value to Raphael Collignon advancing against Rinky Hijikata and is effectively treating that outcome as not yet credible. The contract settles on the player who advances, but if the match is not played, ends tied, or no winner is confirmed by 8 September, it resolves 50-50; on Polygon, the value comes from conditional tokens funded in USDC, so the live price reflects the market’s read on both match completion and result.

This is a useful case for reading how low-probability tennis contracts can be mispriced when the underlying fixture is delayed, moved, or already effectively voided by scheduling. Collignon entered the Winston-Salem draw as the higher-ranked player, with recent listings showing him around ATP No. 38 and Hijikata around No. 95, and tennis model pages and pre-match odds had Collignon only a modest favourite, not a certainty. That sort of profile is exactly where a 0% print can mean either a genuine longshot or a stale market that has not caught up with a match already under way or altered by the draw.

The key catalysts are straightforward: whether the ATP’s Winston-Salem schedule keeps the match on the board, whether an official start and completion are posted, and whether any withdrawal, walkover or rescheduling changes the settlement path. The tournament’s own schedule page says times are tentative and subject to change, while the event runs 23–29 August at Wake Forest University, so traders watch official order-of-play updates, live score feeds and any late draw corrections rather than the abstract matchup alone.
