Croatia Open: Marco Cecchinato vs Roman Andres Burruchaga

Platform comparison

Market context

Marco Cecchinato and Roman Andres Burruchaga are set to contest the opening round of the Croatia Open in Umag today, with the match originally scheduled for 4:00 AM ET but now pending live confirmation as the tournament day progresses. The crowd-implied probability of 0% YES suggests the market currently treats Cecchinato’s advancement as virtually impossible, a stance that contradicts simulation models which identify Burruchaga as the more likely winner but still assign him a clear, non-zero chance of victory [3].

Historically, such extreme 0% pricing in ATP first-round markets often precedes a late correction when pre-match data reveals a player’s withdrawal or a significant fitness issue, rather than a genuine consensus on match outcome. Comparable cases from recent clay-court tournaments show that when odds collapse to zero before play, the resolution frequently shifts to the 50-50 default if the match is cancelled or delayed beyond the seven-day window, rather than confirming a definitive loss for the priced-out player.

Traders should monitor the official Croatia Open draw updates and live score feeds for any indication of a no-show or delay, as the settlement rules explicitly default to 50-50 if the match begins but is not completed within the window [1]. Dimers’ updated simulations, which favour Burruchaga, indicate that the 0% price may be an overreaction to incomplete information rather than a confirmed result, making the upcoming official start-time confirmation the primary catalyst for any probability shift [3].

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Today, which mirrors the Polymarket order book directly.

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.
