Roland Garros ATP: Raphael Collignon vs Aleksandar Vukic

Platform comparison

Active sub-markets

Market context

Collignon and Vukic are scheduled to meet in the opening round of Roland Garros on 24 May 2026. The match carries a 100% crowd-implied probability favouring Collignon's advancement, suggesting market participants view this as a heavily one-sided fixture. Settlement occurs by 31 May, allowing a seven-day window for completion or rescheduling before the market resolves to 50-50 if unfinished.

The extreme probability skew warrants scrutiny against comparable early-round matchups at Grand Slams. Vukic, an Australian ranked outside the top 100 in recent seasons, has faced seeded opponents in opening rounds before without triggering such lopsided odds. Collignon's ranking and seeding status would need to substantially exceed Vukic's for this probability to reflect standard clay-court form differentials. Historical precedent suggests even significant ranking gaps rarely produce 100% certainty in tennis markets, where surface suitability, recent tournament results, and head-to-head records typically create meaningful uncertainty.

Traders should monitor official Roland Garros draw confirmations and any late withdrawals or injury announcements affecting either player's fitness. Collignon's recent clay-court performance and Vukic's form leading into the tournament will clarify whether the probability reflects genuine dominance or market mispricing. Weather delays at Roland Garros frequently compress schedules; any postponement beyond the initial date could pressure settlement mechanics. Confirmation of seeding assignments and recent ATP rankings updates, typically released one week before the tournament, will provide concrete data to test whether this probability remains justified.

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.
