Roland Garros ATP: Stan Wawrinka vs Arthur Fils

Platform comparison

Active sub-markets

Market context

Arthur Fils is priced at about 86% on Polymarket, leaving Stan Wawrinka near 14% on the other side of the USDC-settled, Polygon-based contract. That sits well below the wider match pricing seen elsewhere: FanDuel has Fils around -800 against Wawrinka at +500, which implies the market expects the Frenchman to progress comfortably. For Polymarket users, the key point is that the contract resolves on who advances, not who wins sets or games, so a straight-sets, four-set, or five-set route all settle the same way unless the match is abandoned.

That 14% Wawrinka price mostly reflects age, ranking, and surface context rather than a strong upset narrative. Fils is the higher-ranked player and the home-side favourite, while Wawrinka remains capable of taking a set or dragging the match into an awkward rhythm on clay. Comparable Grand Slam first-round pairings between a seeded or emerging home favourite and a much older wildcard or veteran usually trade in the low-teens for the underdog unless there is injury news or clear fatigue on the favourite. The market is therefore reading this more as a routine advancement spot than a live toss-up.

The main catalysts are straightforward: official order of play, any late fitness updates, and whether the match starts on schedule at Roland Garros. ATP reporting noted this as one of the first-round matches to watch, and that matters because any postponement or reshuffle can change how traders price rest, conditions, and withdrawal risk. If the match is played, the resolution is binary on advancement; if it is not played at all, ends in a tie, or drifts beyond seven days without a winner, the contract settles 50-50 under the market rules.

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.
