Livesport Prague Open: Mai Hontama vs Lilli Tagger

Platform comparison

Market context

Mai Hontama and Lilli Tagger were scheduled to meet in the Livesport Prague Open women’s singles, a match that would resolve on whether either player advances from that head-to-head. In prediction-market terms, a **YES** share pays out if the named outcome happens, while a **NO** share pays out if it does not; here, the market is about whether Mai Hontama advances, with the alternative outcome being Lilli Tagger advancing. If the match is not completed in a way that produces a winner, the market rules also allow a 50-50 settlement in some delay or cancellation cases.

The current crowd-implied probability of **0% YES** suggests the market is pricing almost no chance that Mai Hontama advances under the contract’s definition. That is consistent with comparable tennis price signals around the fixture: Tennis Tonic’s preview on 23 July 2026 identified Lilli Tagger as the pick to win, with initial odds of 1.52 for Tagger and 2.52 for Hontama, while a live scoreboard listing also showed Tagger advancing status in the event thread.[1][3] On that basis, a zero-priced YES share is best read as a strong consensus on the opposite side rather than as a literal statement that the match cannot go the other way.[2][3]

For traders, the key catalysts are straightforward: official tournament scheduling, any withdrawal or walkover, and whether the match is played to completion before the settlement deadline. The market description makes clear that a cancellation, tie, or delay beyond seven days from the scheduled date can force a 50-50 result, so changes in the Prague Open order of play and any injury or medical updates matter more than general pre-match chatter. A live event page and sportsbook-style preview both pointed to the same pairing, which is useful because prediction markets on tennis often move most when the draw, timing, or participation itself changes rather than on broad form narratives.[1][3]

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.
