Wimbledon WTA: Barbora Krejcikova vs Mirra Andreeva

Platform comparison

Market context

The underlying event is the second-round WTA tennis match at Wimbledon between Barbora Krejcikova and Mirra Andreeva, scheduled for 6:00 AM ET on 1 July 2026 at Centre Court, London. In prediction markets, a YES share pays out if the market resolves in favour of the stated outcome (here, Krejcikova advancing), while a NO share pays if the outcome does not occur. This specific market currently implies a 100% probability that Krejcikova will win, a figure that demands scrutiny given recent head-to-head history where Andreeva defeated Krejcikova 7–6, 3–2 before Krejcikova retired in their first-ever meeting[3].

Historical precedents show that 100% implied probabilities in tennis are rare and often signal either a mispriced market or an unreported injury, as Andreeva’s Wimbledon record includes a quarterfinal finish and a first-round exit, indicating volatility rather than certainty[1]. Traders should monitor official WTA injury announcements and Krejcikova’s fitness updates before the match, as any delay beyond seven days or retirement would trigger a 50–50 settlement rather than a decisive outcome[9]. Recent coverage from Sports Illustrated highlights Andreeva’s moneyline advantage at –237 versus Krejcikova’s +182, suggesting the crowd-implied 100% YES may contradict current betting odds[1].

The settlement window closes on 8 July 2026 at 10:00 UTC, so any delay in match completion or post-match disciplinary decisions could alter the resolution. Watch for live score updates on Flashscore or SofaScore, which confirm the match starts at 14:10 UTC on Centre Court[5][6]. If the match begins but is not completed with a winner, the market resolves to 50–50, making real-time monitoring of retirement clauses critical for accurate positioning.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Prediction Market UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
