Wimbledon WTA: Barbora Krejcikova vs Mirra Andreeva

Platform comparison

Market context

The real-world event is the second-round WTA match at Wimbledon between Barbora Krejcikova and Mirra Andreeva, scheduled for 6:00 AM ET on 1 July 2026 at Centre Court, London. This contest pits the French Open champion Andreeva against the two-time Wimbledon finalist Krejcikova in a tightly contested Round of 64 fixture where both players have shown dominant form in their opening rounds[1][5].

Historically, similar high-stakes grass-court clashes between rising stars and seasoned finalists have often resolved with the younger player prevailing after a grueling three-set battle, as seen in Andreeva’s previous 7–6, 3–2 retirement win over Krejcikova where the first set ended in a tiebreak[2]. The current 100% YES probability for Krejcikova advancing appears inconsistent with this head-to-head record and recent analyst picks favouring Andreeva to win in three sets, suggesting the market may be mispricing the likelihood of a Krejcikova victory or conflating “advancing” with “winning the match”[1][3].

Traders should monitor official WTA injury updates, weather conditions affecting Centre Court play, and any post-match retirement announcements, as these dependencies directly determine settlement outcomes[6]. A recent preview from Last Word on Sports notes Krejcikova’s dominant opening round but highlights Andreeva as the tougher unseeded opponent, reinforcing the need to watch for fatigue or tactical shifts during the match[6]. Programmatically, conditional orders should be triggered by live score thresholds—such as Andreeva winning the first set tiebreak or Krejcikova failing to convert break points—to hedge against the 50–50 cancellation clause if the match is delayed beyond seven days[2][7].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

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.

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.
