Market context

The underlying event is already settled: Grigor Dimitrov defeated Marc Polmans 6-1, 7-6(3) in the first round of the 2026 Mallorca Championships on Tuesday, advancing to the second round. The prediction market’s 0% YES probability for Polmans advancing is now a factual reflection of this completed result, not a forecast. In tennis prediction markets, once a match concludes, probabilities collapse to zero for the loser and 100% for the winner; historical cases from Wimbledon and the Australian Open confirm that markets do not retain speculative value post-settlement, making this 0% figure a definitive outcome rather than a trading signal.

Traders should monitor official ATP Mallorca Championship updates for Dimitrov’s next-round schedule and any potential withdrawal announcements, as these will determine the market’s final settlement path. Recent coverage from the Mallorca Championships official site highlights Dimitrov’s 50th tour-level grass win and his polished performance, underscoring his strong form on this surface [3]. No further catalysts exist for Polmans, as his elimination is confirmed; the only dependency is whether Dimitrov advances further or withdraws, which would trigger the 50-50 tie resolution clause if the match is delayed beyond seven days without a winner. The settlement window ending 2026-06-30 remains irrelevant now, as the outcome is already determined.

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.
