Market context

Raphael Collignon meets Casper Ruud at the Geneva Open, with the market still priced at 0% YES for Collignon. That makes Ruud the clear favourite in consensus terms, and the contrarian angle is obvious: if you want Collignon, you are betting against the draw and the class gap rather than against the number. Ruud’s baseline profile is the cleaner fit for outdoor clay, and Geneva has generally rewarded established clay-court names rather than lower-ranked disruptors. Recent previews have also leaned Ruud’s way, with TennisUpToDate’s Geneva Open note picking Casper Ruud for the title and treating him as one of the leading contenders.

For traders, the main catalysts are simple: final order of play, any late injury or withdrawal news, and whether the match is placed early enough on the schedule to avoid weather or backlog issues. The tournament is the ATP 250 in Geneva, staged on outdoor clay in the build-up to Roland Garros, so workload management matters, especially for players balancing one last tune-up with the risk of overexertion. If Ruud is confirmed and physically sound, the consensus should stay with him; if there is any sign of rotation, fitness concern, or a shortened warm-up window, that is where the only meaningful value on Collignon would emerge.

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.
