National Bank Open: Nicolas Mejia vs Lorenzo Musetti

Platform comparison

Market context

Polymarket is pricing this **Nicolas Mejia vs Lorenzo Musetti** contract at **0% YES**, which means the market is treating Mejia’s advance as effectively unpriced on the current book. On Polymarket, buyers are backing conditional tokens settled in **USDC** on **Polygon**, so the contract should only resolve to YES if Mejia advances; if the match is not played, or is delayed beyond the settlement rules, the fallback is the market’s **50-50** outcome rather than a straight win/loss. [1][2]

The main historical frame is the mismatch in ranking and tour level: Musetti is a seeded ATP-level player near the top of the draw, while Mejia is far further down the rankings, and the listed head-to-head is **0-0**, so there is no prior meeting to anchor a close-priced market. Public previews and odds boards are heavily tilted towards Musetti, with one match preview calling for a straight-sets Musetti win and several live/odds listings showing Mejia as a clear outsider. [1][4][5][8][16]

For traders, the key catalysts are practical rather than tactical: whether the match starts on schedule, whether the order of play changes, and whether any withdrawal or walkover is announced before first ball. The match is listed for Montreal on outdoor hard courts, and at least one schedule feed places it at 15:00 UTC; if the fixture is pushed back or not completed, Polymarket’s settlement mechanics become more important than the on-court score.

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.

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%.
