Grodzisk Mazowiecki: Joel Schwaerzler vs Andrea Guerrieri

Platform comparison

Market context

The final in Grodzisk Mazowiecki is a straight ATP Challenger title match between **Joel Schwaerzler** and **Andrea Guerrieri** on outdoor hard courts. Match listings put Schwaerzler around ATP No. 182 and Guerrieri around No. 213, with Schwaerzler the higher seed and Guerrieri the No. 4 seed; both reached the final by beating stronger-ranked opponents in the semi-finals.[1][5][9][14]

For market readers, a **100% YES** crowd price is best read as a fully converged view that the match will be played and produce a winner, not as a statement on who wins. The pair had no prior head-to-head record before this final, which matters for any model that leans on matchup history, and the absence of a prior meeting is consistent across preview coverage.[7][14] In programmatic terms, this is the kind of market where the decisive state variable is binary completion: once the final is officially underway, settlement risk shifts mainly to retirement, walkover, or abandonment rather than form.

The main catalysts are scheduling and tournament operations. The match was listed for 9 August at 11:00 UTC / 13:00 local time on Centre Court, but live score pages already show the final in progress, so a trader watching automated alerts would key off official match status, set completion, and any retirement flag from the scoreboard feed.[3][9][10] Because the settlement rules also fall back to 50-50 if the match is not played at all or is delayed beyond seven days, the practical dependencies are start confirmation, uninterrupted completion, and whether the ATP Challenger event publishes a valid winner before the window closes.[14][20]

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 Polymarket Review UK, 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.
