Market context
Martin Landaluce and Vít Kopřívá are scheduled to meet in the first or early qualifying round of Roland Garros in May 2026. The 100% crowd-implied probability reflects near-certainty that this match will occur and produce a winner, with minimal expectation of cancellation, retirement, or extended delay beyond the settlement window. The scheduling places the fixture at an ungodly hour for North American observers (5:00 AM ET), typical for early-round qualifying matches at the French Open, which reduces casual betting volume and may explain why this contract has attracted limited cross-platform comparison.
Historical precedent suggests that qualifying-round matches at Grand Slams rarely fail to complete. Across the ATP qualifying draws at Roland Garros over the past five years, completion rates exceed 95%, with retirements accounting for roughly 2–3% of outcomes and outright cancellations rarer still. Both players are established professionals with no recent injury flags on public record, though Landaluce's ranking and recent form will be critical to assess as May approaches. The current probability assignment appears consistent with baseline tournament completion risk rather than any specific intelligence about either competitor's fitness or readiness.
Traders should monitor the ATP rankings and entry lists as they crystallise in late April 2026, which will confirm both players' seeding and draw position. Any late withdrawal or injury announcement would trigger immediate repricing. The settlement window closes 7 June, allowing a seven-day buffer beyond the scheduled date—sufficient for rescheduling within the qualifying window but tight enough that extended delays would force a 50-50 resolution. Cross-sportsbook lines, where available, should align closely with the current market probability given the straightforward binary outcome and low external uncertainty.
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.

- What's the difference between YES and NO shares?
- A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
