Market context

Jan Choinski and Yibing Wu were due to meet in the Eastbourne qualifying draw on grass, a format where service holds and short margins often matter more than in slower conditions. Public scoreboards showed the match listed for 20 June 2026, with ATP live and archive pages indicating the contest went ahead and was completed, which is the key factual anchor for how this market should ultimately be read rather than the pre-match price alone.[1][3][5]

A **100% YES** crowd-implied price is only meaningful if the market is already treating the underlying event as effectively settled; in comparable tennis qualifier markets, prices can jump to the extreme once lineups are confirmed, then collapse if a retirement, walkover or schedule change alters settlement mechanics. That matters here because the contract resolves on whether Choinski advances, while a cancellation, tie or delay beyond the stated window would push it to 50-50 under the rules, so the relevant historical frame is not just form but whether the match is actually played to completion.[2][3]

From an access and compliance angle, this is the kind of contract that sits inside a broader prediction-market regulatory split: German users face the GlüStV framework, which is materially stricter around gambling-style activity, while US exposure can still touch CFTC scrutiny if a platform is deemed to offer derivatives-like event contracts. “No-KYC up to $1,500” means lighter onboarding for small balances, not anonymity in a legal sense, and it generally implies that higher-volume participation or withdrawals can trigger identity checks, which affects who can realistically access this market at scale.

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.
