Livesport Prague Open: Maria Timofeeva vs Aliaksandra Sasnovich

Platform comparison

Market context

Maria Timofeeva and Aliaksandra Sasnovich have already played at the Livesport Prague Open, and Timofeeva won the match 6-3, 6-4 in the round of 16.[2] That makes a current crowd-implied probability of 100% YES broadly consistent with a settled head-to-head result rather than an open pre-match view, even though some pre-match models had leaned the other way: one Czech odds page listed Sasnovich as the bookmaker favourite at 1.75, while an independent prediction model gave Timofeeva a 62% win chance.[1][3]

For traders, the key distinction is between sportsbook price, model expectation, and the market’s actual resolution rule. Here the contract pays on who advanced, so once the result was posted it should track the official match outcome rather than any pre-event odds drift.[2] The main catalysts to watch on comparable tennis contracts are late score corrections, walkovers, retirements, or any tournament-level change to the draw, because those are the events that can force a 50-50 settlement if no winner is ultimately recorded within the window. With the match already reported as completed, there is little fundamental scope for a divergent settlement unless the official result is later overturned or voided.[2]

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
