Roland Garros, Qualification ATP: Arthur Fery vs Pedro Martinez

Platform comparison

Active sub-markets

Market context

The Arthur Fery v Pedro Martinez qualifying match at Roland Garros is priced at 0% YES on Polymarket, so the contract is effectively trading as if a Fery advance is no longer expected. On Polymarket, positions settle in USDC on Polygon via conditional tokens, so the live price is the cleanest read-through of what traders think will happen before the tennis authorities post a result or trigger the market’s fallback rules.

The better guide here is not Fery’s short-run form alone, but the surface and the draw context. Tipstop notes Fery has won 6 of his last 10 matches, while Martinez is at 4 of 10, yet the market still leaned to Martinez on price and clay pedigree. That fits the usual Roland Garros pattern: a lower-ranked player can have recent wins, but the qualifier often follows the more established clay-court profile. If the match has already been played, the decisive factor for settlement is simply who officially advances, not how the scoreline looked.

Traders should watch the tournament schedule and any score or retirement updates from Roland Garros as the main catalysts. SofaScore listed the match for 20 May at Court 10 in Paris, while the settlement window runs to 27 May, so delays, walkovers, or an abandoned match still matter under the market rules. If no winner is recorded within seven days of the scheduled date, the contract resolves 50-50, which makes official announcements and the ATP/Grand Slam match status the key inputs rather than private injury chatter.

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.
