Market context

The Bad Homburg Open match between Liudmila Samsonova and Elina Svitolina, originally set for 5:00 AM ET on 23 June 2026, is the real-world event underpinning a Polymarket contract now priced at 100% YES for Samsonova advancing. On-chain, this conditional token trades on Polygon using USDC, locking in a binary outcome where the market resolves to “Samsonova” if she wins, “Svitolina” if she advances, or 50-50 if the match is canceled, tied, or delayed beyond seven days without a winner.

Historically, such 100% pricing in tennis prediction markets has preceded either a walkover, a pre-match injury, or a match never played—cases where the underlying event fails to occur, triggering the 50-50 clause. In the 2024 WTA Bad Homburg Round of 16, similar odds appeared before a player withdrew due to a hamstring strain, leaving the market unresolved until the cancellation clause activated. Traders should note that current crowd-implied certainty does not guarantee Samsonova’s victory, but rather reflects high confidence the match will proceed with her as the likely winner.

Key catalysts include official WTA announcements on player fitness, court conditions, and weather delays in Bad Homburg. A recent Tennis.com projection lists Svitolina as the 69% favourite to win the match, contradicting the market’s 100% Samsonova advance pricing and suggesting a potential misalignment between on-chain sentiment and live form [2]. Traders must monitor the WTA’s live score feed for any withdrawal notices or match delays, as these directly determine whether the 50-50 clause activates [7]. The settlement window closes 30 June 2026 at 09:00 UTC, after which the outcome is final.

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.

FAQ

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does it cost to trade on Kalshi UK?

Zero. Kalshi UK routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, Kalshi UK triggers a quick verification flow that finishes in minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
