Linda Fruhvirtova and Tereza Martincova are scheduled to meet in Istanbul on 5 May 2026, with the match originally set for 7:00 AM ET. The market currently shows 0% implied probability for Fruhvirtova advancing, reflecting the order book on Polymarket where traders have positioned heavily against her prospects in this fixture. Settlement occurs on 12 May 2026, allowing a seven-day window for the match to conclude.
Fruhvirtova, a Czech player born in 2004, has competed primarily on the ITF circuit and lower WTA tiers, whilst Martincova, also Czech and born in 1996, has established herself with multiple WTA main draw appearances and career ranking peaks in the top 100. Historical matchups between players at significantly different career stages and ranking levels typically reflect substantial probability gaps, though the 0% reading suggests the market is pricing this as a near-certainty for Martincova. The absence of any YES-side liquidity indicates minimal backing for an upset scenario.
Traders should monitor official tournament draws and player injury reports from the WTA calendar leading into May 2026. Scheduling changes, player withdrawals, or late-round seeding adjustments could alter match conditions. The settlement window's seven-day buffer provides some protection against minor delays, though cancellation or extended postponement would trigger the 50-50 tie resolution. Recent form data and surface-specific performance metrics for both players on hard courts will become relevant as the event approaches.
This market settles from the official outcome published at https://www.wtatennis.com/scores. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.

Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$35K in lifetime turnover and $0 of resting liquidity puts this market in the around the median by volume for tennis contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.

Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
