Market context

The Stuttgart Open grass-court tournament will host a first-round encounter between French qualifier Giovanni Mpetshi Perricard and Belgian opponent Gauthier Onclin on 10 June 2026. Mpetshi Perricard, ranked around 200th on the ATP tour, has shown volatility across surfaces but possesses a powerful serve that translates well to grass. Onclin, similarly ranked in the lower reaches of the professional circuit, competes primarily on the Challenger tour and rarely features in ATP main draws. The 100% implied probability reflects Mpetshi Perricard's superior ranking and recent tournament activity, though grass-court form for both players remains limited in available data.

Direct head-to-head records between players at this ranking level are sparse or non-existent, making historical precedent unhelpful for calibrating the line. Instead, traders should monitor qualifying results from the Stuttgart event itself—Mpetshi Perricard's path through qualifying rounds will indicate current match sharpness and injury status. Onclin's participation hinges on receiving a wild card or advancing through qualifying, neither of which is guaranteed. The settlement window closes 7 June at 08:00 UTC, creating a tight margin; any withdrawal, illness, or scheduling disruption announced after 3 June could trigger the 50-50 resolution clause if the match remains unplayed beyond 17 June.

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.
