Diane Parry and Alina Charaeva are the two players in a Paris qualifying match scheduled for 16 May 2026, with the market resolving to the player who advances. Polymarket’s order book is showing 0% YES, which usually means no visible liquidity has yet priced a side rather than a true zero chance. For a live tennis market, that is often a sign that traders are waiting for confirmed court, start-time, and line-up information before entering bids, so the implied probability can move sharply once money appears.
On recent form, the available records point to Parry as the more established WTA-level player, while Charaeva has been more volatile and has come through a shorter run of events. Head-to-head data in the search results indicates Parry leads the series 1-0, with their previous meeting won in straight sets. Flashscore’s match data also suggests the contest has already been played or was in progress around the scheduled slot, with set-level stats and break-point numbers published, so the key catalyst is whether an official winner is confirmed, whether the match completed, and whether any retirement or postponement triggers the market’s alternative settlement rules. Recent live-score pages from Flashscore and TennisLive are the most relevant checks for confirmation.
