Market context

Raphael Collignon’s match with Juan Manuel Cerúndolo at Eastbourne is being priced very differently across venues: the prediction market sits at **0% YES** for Collignon, while sportsbook-style listings are still treating the contest as live and unresolved rather than effectively closed. Sofascore and Flashscore both list the fixture for 22 June, and Yahoo Sports had the men’s singles round-of-32 meeting on grass with Collignon involved, which is the kind of setup where a suspended, postponed or already-advanced result can drive a sharp split between exchange pricing and headline match listings.[1][3][6]

The historical frame is mostly head-to-head and surface context. ATP and third-party H2H pages show the pair have already met, with Juan Manuel Cerúndolo holding the more established clay-court profile and Collignon arriving with a lower listed ranking but recent upward movement in form.[2][4] That matters because Eastbourne is played on grass, a surface that often narrows the gap between players whose baseline records look uneven elsewhere. In comparable cases, prediction markets can sit near zero on the “less likely” side when traders expect either a withdrawal, a walkover, or a pricing error to be corrected before settlement, rather than a straightforward on-court upset.[2][4]

For traders, the key catalysts are whether the match is actually completed, whether either player advances by walkover, and whether any official schedule change pushes the event outside the seven-day settlement window. At 16:00 UTC on Monday, the contract is already close enough to the originally scheduled slot that delayed play, retirement, or a tournament feed update would matter more than pre-match hype; if the bracket or live score providers confirm a result, that will dominate the final settlement path.[1][3][6]

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.
