Market context

The real-world event is the WTA 500 tennis match between Liudmila Samsonova and Elina Svitolina at the Bad Homburg Open, scheduled for 23 June 2026. In prediction markets, a YES share pays out if the market resolves to the outcome it supports (here, Samsonova advancing), while a NO share pays out if the outcome does not occur. This specific market currently shows a 100% crowd-implied probability for YES, meaning traders overwhelmingly expect Samsonova to win, though the market will resolve to a 50-50 split if the match is cancelled, tied, or delayed beyond seven days without a winner.

Historical precedents in tennis prediction markets show that 100% probabilities often reflect early consensus rather than certainty, as matches can be disrupted by injury, weather, or administrative delays. Comparable cases from previous WTA tournaments reveal that even heavily favoured players occasionally fail to advance due to unexpected cancellations or three-set losses, which would invalidate a 100% YES position if the market rules trigger a tie resolution. Traders should therefore view this probability as a snapshot of current sentiment, not an immutable guarantee.

Key catalysts to watch include the official start-time confirmation, any pre-match injury reports, and the tournament’s weather schedule for the Kurpark venue. Recent coverage from The Stats Zone notes Samsonova’s recent form includes a loss to Anna Bondar but wins against Noemi Basiletti and Hailey Baptiste, while Last Word on Sports predicts a three-set Samsonova victory [1][2]. Traders must monitor Tennis.com’s live score updates and Eurosport’s broadcast information for any delays or cancellations that could shift the market outcome [3][5].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
