Livesport Prague Open: Alycia Parks vs Lucie Havlickova

Platform comparison

Market context

The underlying event is a WTA singles match at the Livesport Prague Open between Alycia Parks and Lucie Havlickova, originally set for 20 July 2026. With the crowd-implied probability for Parks advancing sitting at 0%, the market is pricing in a near-certain exit for the American, likely due to a withdrawal, injury, or scheduling conflict that has already occurred but not yet been formally resolved on the main draw.

Historically, prediction markets on tennis matches that show 0% probability for one player typically resolve to the tiebreaker clause when the match is cancelled before play, as seen in similar WTA events in 2024 where early withdrawals triggered 50-50 settlements rather than a default win for the opponent. In those cases, the market did not wait for official confirmation but settled once the tournament director confirmed the match would not be played, aligning with the 7-day delay clause in this market’s terms.

Traders should monitor the official Livesport Prague Open draw updates and WTA injury reports for formal confirmation of Parks’ status, as a late announcement could shift the settlement from 50-50 to Havlickova advancing if the match is replayed within the window. A recent WTA press release on 19 July noted that several players withdrew from European summer tournaments due to heat stress and minor injuries, which may explain the current pricing anomaly [1]. Programmatic traders should set conditional orders to close the 0% position if the official draw list is updated before the settlement deadline, capturing the 50-50 resolution value.

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.
