Croatia Open: Flavio Cobolli vs Roman Andres Burruchaga

Platform comparison

Market context

Flavio Cobolli has already lost his Croatia Open Round of 16 match to Roman Andres Burruchaga, with the Argentine top-seed upset 6-2, 6-4 in Umag on Wednesday [1][2]. The prediction market titled “Croatia Open: Flavio Cobolli vs Roman Andres Burruchaga” therefore resolves to ‘Roman Andres Burruchaga’ as the advancing player, making the current 0% YES price for Cobolli advancing a reflection of the completed real-world outcome rather than a speculative forecast [1].

Historically, Polymarket contracts on ATP matches that settle after the event conclude often linger at extreme prices until the conditional token resolution logic executes, especially when the result is unambiguous and widely reported [1][5]. Comparable cases from recent ATP 250 tournaments show that once a match result is confirmed by official ATP feeds and major sports outlets, on-chain prices converge instantly to the true outcome, with volume spiking only during the final settlement window as traders arbitrage stale listings [5].

Traders should monitor the official settlement timestamp on Polygon, as the contract resolves automatically once the match result is ingested into the conditional token oracle, with no further announcements needed [5]. The key dependency is the oracle’s confirmation of Burruchaga’s quarter-final advancement, which is already documented in the tournament’s Wednesday report [1]. With $16.37K in volume already recorded and the match finished, the market’s 0% price for Cobolli is mechanically accurate and will not shift unless the settlement window is delayed beyond seven days, which is not indicated [1][5].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like PolyGram trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
