National Bank Open: Jaume Munar vs Alexander Blockx

Platform comparison

Market context

Jaume Munar and Alexander Blockx are still scheduled for their National Bank Open second-round match in Montreal, and the market is sitting close to a coin flip because there has been no decisive result or walkover. Both players are listed at 0–0 for the match, with Munar’s live ranking shown around No. 45 and Blockx around No. 33, which helps explain why the crowd is pricing this at 50% YES rather than treating either side as a clear favourite.[1][2][4]

The historical frame is thin: the head-to-head is 0–0, so there is no direct tour-level meeting to anchor expectations.[2][5][10] Comparable rating models also point to a near-even contest, with one pre-match estimate putting Blockx only marginally ahead at 50.5% to 49.5%.[13] Munar brings the longer ATP record and more tour mileage, while Blockx has the higher current ranking and stronger recent season win rate in several public stat feeds, which is enough to keep the market balanced rather than directional.[4][13][16]

For traders, the key catalysts are straightforward: whether the match starts on time, whether the tournament schedule changes after earlier-round interruptions, and whether either player withdraws before first serve. Public schedules currently place the match in the Montreal evening slot, and live event listings still show it as an active Round 2 fixture rather than a completed result.[2][6][9] If play is delayed, shortened, or pushed back by more than seven days from the original date without an official winner, the market’s rules point to a 50-50 settlement instead of a player win.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Today, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

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 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 Prediction Today trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
