Market context

Arthur Fery’s quarter-final against Francisco Cerúndolo is a Queen’s Club grass-court match, with Fery arriving off the back of the biggest run of his career and Cerúndolo coming through as the higher-ranked seed.[2][1] That context helps explain the crowd’s **41% YES** price on Fery: it is not a toss-up, but it is also higher than a routine underdog number because home advantage and grass-court form have been material in Fery’s path so far.[2][4] Cerúndolo, however, has also already handled grass-court opposition in this event and is the more established ATP-level player.[2][6]

For prediction-market purposes, the main reference point is that the market settles on who *advances*, not simply who leads when play stops, and a non-played match or a delay beyond seven days would force a 50-50 outcome under the rules described. Comparable tennis markets are usually driven by late fitness updates, walkovers, weather interruptions on outdoor grass, and any order-of-play changes at Queen’s, where schedules can move quickly if earlier matches overrun.[1][3] Traders should also watch official tournament announcements and live match listings, because the listed start times in previews and live-score services can differ slightly depending on broadcast and court scheduling.[1][3][8]

On access, the regulatory picture matters as much as the tennis. If the market is offered in a way that reaches German users, the GlüStV framework is relevant because unauthorised sports wagering or games-of-chance style access can be restricted under German gambling rules. In the US, CFTC reach can matter where a platform is treated as a derivatives venue rather than a pure betting site, so availability may vary by jurisdiction and product structure. “No-KYC up to $1,500” means a user may be able to trade within that exposure band without completing full identity checks, but it does not remove geo-restrictions, sanctions screening, or platform-level limits on who can access this specific market.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
