Roehampton: Michael Geerts vs Radu Albot

Platform comparison

Market context

Michael Geerts and Radu Albot are scheduled to meet at Roehampton on 19 August 2026. The 100% implied probability suggests either strong conviction that the match will proceed as planned or minimal trading activity to challenge that consensus. With settlement closing 7 days after the original date, the market allows for a one-week window before resolving to 50-50 if the match remains unplayed or incomplete.

Geerts, a Belgian player in his mid-twenties, has competed on the ATP Challenger circuit with modest ranking progression. Albot, the Moldovan veteran now in his mid-thirties, has held ATP rankings in the top 40 and remains a regular on the professional tour. Historical precedent at grass-court events like Roehampton shows cancellation rates below 5% absent weather emergencies or player injury withdrawals announced in advance. The venue itself—a traditional warm-up tournament before the latter stages of the summer season—rarely experiences scheduling disruptions beyond standard rain delays that resolve within 24–48 hours.

Traders should monitor the ATP injury report and Roehampton's official draw confirmations through mid-August. Recent weather patterns for southwest London in late August typically favour completion, though August thunderstorms remain a variable. Any announcement of either player's withdrawal or late-round injury would shift the 50-50 resolution risk materially. The settlement window's 7-day buffer is generous relative to typical grass-court tournament schedules, reducing the likelihood of unresolved status at close.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
