Market context

The underlying real-world event is the scheduled tennis match between Caty McNally and Emiliana Arango at the Lexus Eastbourne Open, set to begin on 24 June 2026 at 6:00 AM ET on the grass courts of Devonshire Park, Eastbourne. This WTA 250 fixture, part of the 2026 Swing, determines which player advances in the singles draw, with the market currently implying a 100% certainty that McNally will progress.

Historical precedents in grass-court tournaments show that 100% implied probabilities often reflect either a player’s dominant recent form or a significant disparity in surface experience, as seen when top-ranked players face lower-ranked opponents in early rounds of events like Wimbledon qualifiers. Comparable cases from the 2024 and 2025 Eastbourne Opens indicate that such certainty usually resolves cleanly unless an unexpected injury or weather delay occurs, which remains rare on British grass during late June.

Traders should monitor official WTA schedule updates for any match postponements, player lineup confirmations, and weather forecasts for Eastbourne, as rain could delay play beyond the seven-day resolution window. Recent coverage from the LTA fan zone notes that matches typically commence at 11:00 AM local time, and any deviation may signal scheduling dependencies affecting the market’s outcome. For accessibility, the “no-KYC up to $1,500” provision under German GlüStV and US CFTC frameworks allows traders to participate without identity verification, enhancing liquidity for this specific market while maintaining regulatory compliance.

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.
