Market context

Marcos Giron has already secured a 2–1 victory over Charles Broom in the Lexus Eastbourne Open Qualification, with the match concluding on 21 June 2026 at Court 1 in Eastbourne, England[6]. The crowd-implied probability of 100% YES for Giron advancing is therefore not a speculative forecast but a reflection of a completed real-world result, rendering the market a certainty rather than a prediction.

Historically, markets with 100% pricing on tennis outcomes post-match completion are rare anomalies in prediction markets, as most platforms resolve immediately once the final score is confirmed; comparable cases from the 2025 ATP season show that lingering markets with full certainty typically stem from delayed settlement windows or administrative errors, not genuine uncertainty[5]. In this instance, the 100% figure aligns with the factual outcome, not a trader’s expectation of an unplayed event.

Traders should monitor the official ATP Tour settlement confirmation for this match, as any discrepancy between the live result and the platform’s resolution could trigger a 50–50 fallback if the match is deemed unplayed due to technical cancellation[5]. No further announcements are expected, but the settlement window ending 2026-06-27 remains the sole dependency for final resolution, with no live action to influence the outcome[4]. The market’s status is entirely dependent on administrative confirmation, not competitive performance.

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.
