Market context

The Libema Open grass-court tournament in 's-Hertogenbosch will host a second-round encounter between Canadian Felix Auger-Aliassime and Hungarian Marton Fucsovics on 11 June 2026. The current crowd-implied probability sits at 100% for Auger-Aliassime's advancement, suggesting near-unanimous confidence in the Canadian's progression. This extreme skew warrants scrutiny, as settlement extends to 18 June, allowing seven days for complications including injury withdrawal, scheduling disruption, or match cancellation.

Auger-Aliassime holds a 3–1 career record against Fucsovics across hard and clay surfaces, though grass presents a different dynamic. Fucsovics has demonstrated occasional upset capability on grass—he reached the Halle semi-final in 2019—and possesses a serve-and-volley toolkit suited to quick courts. The 100% probability reflects Auger-Aliassime's ranking advantage and recent form rather than match-specific tactical analysis. Historical precedent shows grass tournaments frequently produce unexpected results due to surface-specific skill sets and variable court conditions.

Traders should monitor official tournament draws and player fitness updates through the ATP's injury reporting channels. Auger-Aliassime's recent performance at preceding grass events will signal preparation quality. Fucsovics's qualifying results, if applicable, provide insight into match sharpness. The settlement window's seven-day buffer creates exposure to weather delays common at Dutch grass tournaments; the 50-50 resolution clause becomes relevant if scheduling pushes beyond the deadline without completion. Current pricing leaves minimal margin for underdog value, though surface-specific variables merit closer examination before settlement.

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.
