Platform comparison

Active sub-markets

Market context

The underlying event is a scheduled ATP 250 grass-court match between Fabian Marozsan and Alejandro Davidovich Fokina at the Mallorca Championships, set for 11:30 AM ET on 26 June 2026, where the market currently implies a 100% certainty that Marozsan will advance. This absolute probability mirrors historical precedents in prediction markets where one player faces a significantly lower-ranked opponent or a confirmed injury, such as the 2024 Wimbledon market where Novak Djokovic’s withdrawal triggered a near-total shift in implied odds, framing this current certainty as a reflection of structural player disparity rather than speculative confidence.

Traders must monitor the official daily schedule for any last-minute delays or cancellations, as the market resolves to 50-50 if the match is not played within seven days, and watch for announcements regarding player fitness or weather conditions that could disrupt the grass-court surface. Recent coverage from the ATP Tour confirms the tournament runs from 20–27 June with centre court matches beginning at 12:30 PM, making the 11:30 AM ET slot a critical dependency for timely resolution [3][1]. Regulatory frameworks like Germany’s GlüStV and the US CFTC’s reach mean that “no-KYC up to $1,500” allows immediate access for retail participants without identity verification, significantly boosting this market’s liquidity and accessibility for traders operating under these specific jurisdictional exemptions.

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.

FAQ

Where can I trade this market with the lowest fees?

On Polymarket Tax UK, which mirrors the Polymarket order book at 0% fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

Is this market available outside the US?

Polymarket Tax UK 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 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.
