Pronóstico: Granby: Daniil Glinka vs Philip Sekulic

Platform comparison

Market context

The Granby Challenger match between Daniil Glinka and Philip Sekulic, originally set for 15 July 2026 at 14:00 local time, has already passed without a result, leaving the Polymarket contract for Glinka advancing at a stark 0% implied probability. On-chain, this USDC position on Polygon trades as a conditional token reflecting a market that believes the match was either cancelled, postponed beyond the seven-day settlement window, or resolved in Sekulic’s favour before the contract could capture Glinka’s advancement.

Historically, tennis prediction markets on Polymarket that hit 0% after a scheduled date often stem from cancellations due to weather, player injury, or tournament restructuring rather than a decisive loss. Comparable cases from 2024–2025 Challenger events show that when a match is not played at all, the protocol defaults to a 50–50 resolution, yet the current 0% suggests traders have priced in a confirmed non-play or a Sekulic win that bypassed the conditional token’s trigger for Glinka.

Traders should monitor the official Granby Challenger schedule and ATP Challenger Tour announcements for any retroactive match results or cancellation notices that could trigger the 50–50 clause. Tennis Tonic’s pre-match analysis favoured Glinka in three sets with odds of 1.50, but the absence of a live result post-15 July implies the outcome may now depend on tournament administrative decisions rather than on-court performance [2]. Any update confirming the match was played and completed will override the current zero probability, while a formal cancellation notice would lock in the 50–50 settlement.

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

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.
