GP SAR La Princesse Lalla Meryem: Petra Marcinko vs Yelyzaveta Kotliar

Platform comparison

Active sub-markets

Market context

Petra Marcinko and Yelyzaveta Kotliar are due to meet in the WTA Rabat second round, but Polymarket is pricing the contract at 0% YES, which means the market is currently implying no credible path to a settled Marcinko win. On Polymarket, positions sit on Polygon and settle in USDC through conditional tokens, so the trade is really about the match being completed and officially assigned, not just who appears stronger on paper.

The closest guide to that price is how similar WTA match markets behave when the event is effectively over in the crowd’s view: if a player has already withdrawn, the draw has been rewritten, or the fixture has been removed from the live schedule, the contract can drift to zero long before an official result arrives. Here, the public tennis feeds list the pairing as a live Rabat match, but the 0% print suggests users have either not found value in Marcinko or are treating the market as stale, suspended, or dependent on an administrative update rather than a normal head-to-head outcome.

The main catalysts are straightforward: an official court order, any late withdrawal, and whether the WTA draw continues to list the match as active or replaces it with a walkover. Match trackers such as SofaScore and Flashscore were still carrying the fixture, which matters because Polymarket outcomes depend on the final official status by the settlement window. If the match is played and a winner is recorded within seven days, the conditional token resolves normally; if it is not played at all, or drifts beyond that limit without a winner, the market falls to 50-50.
