Market context

The Mallorca Championships Round of 32 match between Damir Dzumhur and Vit Kopriva is scheduled for Tuesday, 23 June 2026, at 12:00 pm local time in Santa Ponsa, Spain. Despite the on-chain price on Polymarket showing a 0% probability for Dzumhur to advance, traditional sportsbooks list Kopriva as the favourite with an implied 60.8% win chance, while Dzumhur holds a 45.5% implied chance[1]. This stark divergence between the conditional token market and the moneyline suggests either a liquidity gap in the prediction market or a specific on-chain event that has not yet been priced into the underlying odds.

Historically, similar 0% pricing on Polymarket for tennis contracts has occurred when a player is injured or withdrawn before the match begins, yet the market fails to update the conditional token price until the official result is confirmed on the blockchain. In past ATP events, such as the 2024 Mallorca Open, contracts that resolved to 50-50 due to cancellations initially showed skewed prices before the on-chain oracle corrected the settlement[1]. Traders should scrutinise whether Dzumhur has withdrawn, as the 0% price may reflect a known withdrawal not yet reflected in the public odds, or a failure in the oracle to update the price post-withdrawal.

Key catalysts include the official ATP Tour match status update and any announcements from the Mallorca Championships regarding player withdrawals or delays. The match is set to start at 10:00 UTC, and any delay beyond seven days without a winner will trigger the 50-50 resolution clause[1]. Traders must monitor the live score feed on the ATP Tour website for real-time confirmation of the match status, as the on-chain settlement depends entirely on this official data[5]. A recent prediction from a tennis analyst suggests Dzumhur could win in three sets, which contradicts the current market pricing and warrants further investigation into the source of the 0% probability[2].

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
