Warsaw: Aliona Falei vs Urszula Radwanska

Platform comparison

Market context

Aliona Falei’s meeting with Urszula Radwanska in Warsaw is priced as near-certain on the prediction market, but the live tennis data still matters because this is a WTA 125-level event where withdrawals, scheduling shifts and retirement outcomes can move a contract away from a simple winner-vs-winner settle. The market is currently at **100% YES**, while TennisTemple’s pre-match model shows **73% for Falei** and Flashscore/related scoreboards list Falei as the shorter-priced side, which points to a meaningful gap between sportsbook-style pricing and the crowd’s certainty. [5][2]

The main frame for reading that number is the pair’s profile rather than any head-to-head history: TennisMajors and TennisStats both show **no prior professional meetings**, so there is no direct matchup record to anchor consensus. [1][3] Falei’s recent level looks stronger on the numbers available, with TennisStats listing a 2026 win rate above **70%** and a better last-12-month record than Radwanska, while ESPN’s player page shows Radwanska at **2-5** in 2026 singles at the time of publication. [3][16] That combination makes a Falei advance the base case, but it does not fully justify a perfect market price on its own. [3][16]

Traders should watch for two things before settlement: whether the match actually starts on the published Warsaw schedule, and whether it is completed without a retirement or cancellation. Flashscore, Sofascore and 365Scores all still list the fixture for **3 August 2026** in Warsaw, but time changes or late withdrawals can happen in lower-tier women’s events, especially when players are moving through a dense summer calendar. [2][7][9] If the match is delayed beyond seven days without a winner, the market rules force a **50-50** outcome, so any venue or order-of-play announcement matters as much as form.

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
