Market context

James Duckworth, the Australian right-hander ranked around 65th, faces Rafael Jodar of Spain in the opening round of Roland Garros 2026. The match was originally scheduled for 27 May at 5:00 AM ET, though the 0% implied probability suggests either a withdrawal, cancellation, or administrative issue has already surfaced in the market's assessment. Settlement occurs 3 June 2026, allowing a seven-day window for completion or resolution under the stated terms.

Duckworth has competed consistently on the ATP circuit since 2012, with modest Grand Slam returns—he rarely advances past early rounds at Roland Garros, where clay has historically exposed his baseline consistency. Jodar, a lower-ranked Spanish qualifier or entry, represents the type of opponent where Duckworth's experience should theoretically prevail, yet the market's complete rejection of a Duckworth outcome suggests either player availability concerns or a significant ranking disparity not reflected in the basic framing. Historical precedent shows that when crowd probability collapses to zero before a scheduled match, withdrawal or injury announcements typically follow within 48 hours of the original date.

Traders should monitor ATP official draws and injury reports through late May 2026, particularly any updates on Duckworth's fitness or Jodar's confirmation in the draw. French Open scheduling occasionally shifts matches between courts and time slots, which could affect the settlement window if delays push resolution beyond the seven-day threshold. Any announcement of a walkover, retirement mid-match, or confirmed cancellation will trigger the resolution criteria outlined; absence of either player at court would likely resolve the market to 50-50 under the tie or non-completion clause.

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
