Cincinnati Open: Yulia Putintseva vs Liudmila Samsonova

Platform comparison

Market context

The Cincinnati Open first-round match between Yulia Putintseva and Liudmila Samsonova is the event behind this market, and a YES share pays if Putintseva advances while a NO share pays if Samsonova advances. If the match is not played, is tied, or is still unresolved more than seven days after the scheduled date, the market falls back to 50-50.

A current 0% YES price points to the market expecting Samsonova to be the more likely winner, which fits the recent context: the pair were scheduled on the Cincinnati hard courts and live scores now show Samsonova ahead, with one source recording a completed result in her favour and another noting a straight-sets scoreline. In tennis prediction markets, a near-zero price usually reflects either an outcome already trending towards settlement or a very strong favourite, rather than a balanced contest.

Traders should watch for the official match status, any changes to the draw order, and whether the score is final or merely live-in-progress, because those details decide whether the market settles on a winner or reverts to the 50-50 rule. The important dependency here is straightforward: if play was completed and Samsonova advanced, NO resolves; if the fixture was abandoned before a winner, the fallback applies.
