Canadian Open: Juan Manuel Cerundolo vs Hamad Medjedovic

Platform comparison

Market context

Polymarket is pricing this Canadian Open match at **100% YES**, so the contract is effectively trading as if Juan Manuel Cerundolo will advance over Hamad Medjedovic. On-chain, that means buyers are paying USDC on Polygon for the conditional token that settles to the named winner if the match produces a result, while a non-played match or a delay beyond the market’s 7-day window would force a 50-50 outcome instead.

The historical frame is mixed but informative. Medjedovic leads the head-to-head 2-0 overall, with both wins coming on clay at Roland Garros in 2023 and 2025, while Cerundolo has the higher year-to-date win rate in the available stats and both players entered Montreal on hard courts rather than clay.[1][10] That matters because the current event is a hard-court ATP 1000 match, and the surface shift weakens direct read-across from their French Open meetings.[6][7]

A trader should watch for simple execution risk rather than elaborate scenario shifts: official order-of-play updates, any rescheduling, and whether the match starts and finishes inside the settlement window. Public listings showed the fixture in Montreal for 3 August or 4 August depending on the feed, which underlines that draw timing and live scheduling can move around during an ATP Masters event.[2][4][8] If the match is completed, the market should resolve cleanly; if it is postponed or interrupted, the key question becomes whether the result lands before 10 August 2026 14:00 UTC.[12][13]

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

UK Frequently Asked Questions

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 Kalshi UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
