Grodzisk Mazowiecki: Andrea Guerrieri vs Daniil Glinka

Platform comparison

Market context

Andrea Guerrieri meets Daniil Glinka in the Grodzisk Mazowiecki Challenger semi-final, a match the crowd has priced at **57% Yes** for Guerrieri. That sits above the 365Scores/odds-screening consensus, where Guerrieri is shaded only narrowly in the market at around **1.78** versus **1.90** for Glinka, implying a much closer contest than the prediction market suggests.[4][12] Tennis Temple’s live model also leans towards Glinka, giving him roughly **74%** win probability in its match page, which is the clearest divergence versus the current crowd price.[3]

The recent statistical frame is mixed rather than decisive. Tennis Temple lists Glinka ahead in ranking terms on the live page, while Tennis Tonic’s preview still called Guerrieri the pick to win, expecting a three-set match and noting Guerrieri as the initial odds favourite.[3][4] That sort of split is typical in Challenger-level semi-finals, where small pricing gaps can reflect volatility more than a stable edge; in practice, the market is often reacting to surface form, live fitness, and any minor schedule advantages rather than a clean class difference.[4][12]

For traders, the main catalysts are whether the match starts on time, whether either player is moved by the organiser, and whether any walkover, retirement or rain interruption changes settlement risk, because this contract only resolves to Yes if the match is completed in normal play.[18] Sofascore and 365Scores both list the fixture for **8 August 2026**, so any late cancellation, delay beyond seven days, or partial completion would push the outcome to the market’s non-win settlement case rather than a straight player result.[1][5][18]

FAQ

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.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

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.
