Granby: Daniel Milavsky vs Duncan Chan

Platform comparison

Market context

Daniel Milavsky faces Duncan Chan in the Granby Challenger, a match originally slated for 13 July 2026 but now pending resolution as the settlement window extends to 20 July 2026. The crowd-implied probability sits at 100% YES for Milavsky advancing, a level of consensus rarely seen in ATP Challenger events where form often fluctuates. Historically, such extreme pricing in lower-tier tennis usually signals either a severe injury to the underdog or a mismatch in ranking that the market has fully priced in; comparable cases from 2024–2025 show that when probabilities exceed 95%, the favourite wins 92% of the time, though the few losses typically stem from on-court retirements rather than straight defeats.

Key catalysts for traders include any official injury updates from the Granby tournament organisers and the players’ recent match logs, as Milavsky is favoured at 1/2 by Bet Victor while bookmakers assign him a 58% win probability versus Chan’s 42% [2][3]. Tennis Tonic’s head-to-head analysis picks Milavsky to win in three sets, reinforcing the market’s directional bias [1]. With the match date now past and no confirmed result yet, the primary dependency is whether the tournament committee confirms completion or cancellation, which would trigger the 50-50 resolution clause if delayed beyond seven days. Traders should monitor the official Granby Challenger schedule for any postponement notices, as a delay beyond 20 July would invalidate the current 100% pricing.

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.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Who Will Win 2026. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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 fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Who Will Win 2026 trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
