Geneva Open: Mariano Navone vs Jaume Munar

Platform comparison

Active sub-markets

Market context

Mariano Navone and Jaume Munar are scheduled to meet at the Geneva Open, and Polymarket’s contract on the match is trading at 0% YES, effectively pricing the market as not yet assigned a live outcome. On Polymarket, users are holding USDC on Polygon against conditional tokens tied to the result, so the key question is whether Navone advances or Munar advances within the settlement rules, not simply who is nominally favoured on court. If the match is not completed and neither player is confirmed through the stated resolution path, the contract can still fall back to its tie or no-contest logic, including the seven-day delay clause.

The broader form line is relatively tight. Recent previews have treated this as close to even, with Navone and Munar both sitting around the top-40 level and one independent model giving Navone a 52% edge. That matches the exchange pricing seen elsewhere, where Navone has been listed around 1.80 and Munar around 2.00, implying only a narrow gap. In practical terms, a 0% live contract on Polymarket is less a statement on match strength than a sign that the market is still waiting for a resolvable, standardised event state.

For traders, the main catalysts are the official order of play, any delay on Geneva’s clay courts, and whether the match is finished cleanly rather than interrupted. Sofascore listed the match for 21 May at 11:00 UTC, while coverage from 20 May suggested Navone in three sets, underlining how little separates them. Any scratch, retirement, suspension, or postponement matters because the contract’s settlement does not only depend on the on-court winner; it also depends on whether the match is played, completed, or delayed beyond the seven-day window.

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.
