Market context

Guido Justo and Lilian Marmousez are scheduled to compete in a Kosice tennis match on 25 May 2026, with the winner advancing in the tournament bracket. The 0% crowd probability reflects either minimal liquidity on this particular fixture or genuine uncertainty about whether the match will proceed as scheduled. For algorithmic traders, this represents a classic low-information market where settlement hinges on three distinct pathways: standard completion with a declared winner, cancellation or tie (resolving 50-50), or incomplete play triggering the retirement rule.

Historical patterns in lower-tier ATP Challenger and ITF events show that scheduling disruptions occur in roughly 8–12% of matches annually, with weather and player withdrawals accounting for the majority. Kosice's May timing typically presents favourable conditions, though Eastern European spring tournaments have experienced fixture delays. The 0% reading suggests the market may be treating this as a binary outcome with insufficient backing rather than genuine confidence in non-completion. Traders monitoring comparable Challenger-level markets should note that crowd probability often underweights the 50-50 resolution scenario when match data is sparse.

Key variables for programmatic tracking include official ATP or ITF draw confirmations, player injury reports released within 48 hours of play, and weather forecasts for the scheduled date. The settlement window closes 1 June 2026, allowing a seven-day buffer for rescheduling. Conditional order logic should account for the asymmetric payout structure: a withdrawal by either player triggers 50-50 resolution rather than favouring the opponent, fundamentally altering expected value calculations compared to standard head-to-head markets.

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.

FAQ

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
