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, has already passed its scheduled start time, yet the prediction market on Polymarket still shows a 0% implied probability for Glinka advancing. This contract, settled in USDC on Polygon via conditional tokens, appears to be pricing in a cancellation or delay beyond the seven-day resolution window rather than a live contest outcome.

Historically, similar tennis markets on Polymarket that retain 0% pricing post-scheduled time typically resolve to the 50-50 tie condition when matches are abandoned without a winner, as seen in previous Challenger-level cancellations due to weather or player injury. The current pricing suggests traders expect the match to be declared void, triggering the automatic 50-50 settlement rather than a decisive result for either player.

Traders should monitor official ATP Challenger Granby announcements for confirmation of match status, particularly any notices regarding delays beyond the seven-day threshold or cancellations. Recent coverage from Tennis Tonic initially favoured Glinka with 1.5 odds, predicting a three-set win, but that analysis predates the current market stagnation and does not reflect the on-chain pricing shift [1]. The key dependency remains the tournament’s official resolution on whether the match will be replayed or declared incomplete.

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.

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.

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.
