Market context

Gianluca Cadenasso’s Roland Garros qualifying match against Leandro Riedi is the live event to watch, with the market still showing 0% YES even though the fixture is listed for 20 May and multiple tennis scoreboards are carrying it as an upcoming first-round qualifier. That gap usually points to a data or listing issue rather than a settled sporting outcome, so the immediate question is whether the match is confirmed to go ahead on court and within the normal qualifying schedule.

When a tennis market sits at an extreme such as 0%, comparable cases often hinge on basic availability rather than form: late withdrawals, walkovers, or schedule slips can leave a market effectively frozen until an official result is posted. Riedi is the more established tour-level name and is being priced as the clear favourite on bookmaker-style lines, but the settlement here depends only on who advances, not on set score or margin.

The main catalysts are the French Open qualifying order of play, any last-minute injury or withdrawal reports, and whether the match is actually completed before the seven-day settlement deadline. Live schedule pages from Sofascore, Flashscore and LiveScore are currently the best confirmation sources, while the Kalshi listing shows the market is intended to resolve from the qualifying match outcome itself. If the contest is postponed beyond the window or never starts, the market can fall back to a 50-50 settlement.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

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.
