Market context
Michael Geerts and Lucas Poullain are scheduled to meet at Roehampton on 20 August 2026. The Polymarket contract currently prices Geerts's advancement at 26 cents per share, implying a roughly one-in-four chance he progresses past Poullain. This valuation reflects a significant underdog position for the Belgian player, though the settlement window extends to 27 August, allowing a week's buffer for delays or rescheduling before the market resolves to 50-50.
Geerts has competed primarily on the Challenger circuit and lower ATP tiers, whilst Poullain, a French player, has similarly operated outside the top 100. Historical matchups between players at this ranking level show considerable volatility—head-to-head records often prove poor predictors when both competitors lack consistent tour exposure. Recent surface-specific form matters substantially; Roehampton's grass courts favour players with serve-and-volley patterns or explosive baseline games, and neither player's public record suggests a pronounced grass-court specialisation that would decisively shift the 26% probability.
Traders should monitor the ATP and Challenger draw confirmations as the tournament approaches, particularly any late withdrawals or ranking fluctuations that might alter seeding or scheduling. Injury reports and recent match results from July onwards will provide concrete data on current form. The conditional token structure on Polygon means the contract will settle definitively only if the match concludes within the seven-day window; any cancellation, tie, or unresolved status triggers the 50-50 split, a mechanic that introduces settlement risk independent of on-court performance.
Methodology
This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Qué Es, which mirrors the Polymarket order book directly.
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.
