Roland Garros ATP: Martin Landaluce vs Vit Kopriva

Platform comparison

Active sub-markets

Market context

Martin Landaluce and Vít Kopřívá are scheduled to meet in the opening rounds of Roland Garros in May 2026, with the crowd-implied probability sitting at 100% for Landaluce's advancement. The Spanish player, born in 2005, has been climbing the junior rankings and transitioning to the ATP circuit, whilst Kopřívá, a Czech competitor, operates at a lower ranking tier. The 100% reading suggests near-certainty in the market's view, though this extreme probability warrants scrutiny given the inherent variance in early-round clay-court tennis.

Historical precedent shows that overwhelming favourites in early Roland Garros rounds—particularly when facing unseeded opponents—do advance roughly 85–90% of the time across comparable matchups. However, clay-court tennis introduces friction that can upset form lines; upsets in first and second rounds occur at measurably higher rates than the crowd's consensus typically reflects. Landaluce's youth and relative inexperience at the professional level on clay, despite his pedigree, creates a structural risk that the 100% probability does not price.

The settlement window closes 4 June 2026, allowing seven days beyond the scheduled 28 May date for completion. Key variables include Landaluce's fitness and clay acclimatisation in the weeks leading to the tournament, any late-stage draw changes, and weather disruptions typical of Paris in late May. Traders should monitor ATP tour updates and Landaluce's warm-up tournament results in April and May; a poor showing on clay before Roland Garros would represent a material catalyst for repricing.

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.
