National Bank Open: Panna Udvardy vs Eva Lys

Platform comparison

Market context

Polymarket is pricing this contract at **100% YES** today, which means the market is effectively treating **Panna Udvardy advancing** as a done deal and embedding no material chance of an Eva Lys win or a settlement fall-back to 50-50. On Polymarket, the position is held in USDC on Polygon through conditional tokens, so the final outcome depends on the official match result and the market’s resolution rules, not on who looks stronger on paper.[3]

That reading is notable because external tennis pricing has not been unanimous. Some pre-match bookmakers and odds compilers have shown Lys as the favourite, with implied probabilities in the low-to-mid 60s for Eva Lys and around the mid-30s for Udvardy, while other previews have tipped Udvardy or called the match close.[2][7][13][16][17] For Polymarket users, the key comparison is not the pre-match handicap itself but whether the contract’s 100% print is reflecting a fully confirmed result, a stale order book, or confidence that the on-court outcome is already beyond doubt.

The catalysts to watch are straightforward: official tournament scheduling, any late withdrawal or walkover, and whether the match is actually completed or only started. Polymarket’s rule set says a pre-start walkover settles 50-50, while an in-play retirement, default or disqualification resolves to the player who advances.[3] Tournament listings and live-score services are the quickest ways to verify whether the scheduled first-round tie in Toronto has been played, postponed or ended early.[2][4][14]

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 PolyGram, which mirrors the Polymarket order book directly.

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

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

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.
