National Bank Open: Emerson Jones vs Lanlana Tararudee

Platform comparison

Market context

Emerson Jones’ National Bank Open meeting with Lanlana Tararudee is priced by the market at 33% for Jones to advance, which leaves Tararudee as the clear favourite on the contract. That sits broadly in line with the on-court picture: Tararudee is ranked No. 78 to Jones’ No. 139, and the pair’s only previous meeting went Tararudee’s way in straight sets at an ITF hard-court event in 2024.[1][4][11]

The wider form guide also leans towards Tararudee. Flashscore notes that she has recently added wins over two Czech players in Prague, while Jones has just three career tour wins, including one each in Brisbane and Miami this year.[1][12] Tennistemple’s comparison shows Tararudee with a stronger 2026 record and career win-loss profile, although Jones has already shown she can beat higher-ranked opposition, including Tatjana Maria in Brisbane.[4] Against that backdrop, the current 33% implied probability for Jones looks more like a live underdog price than a disagreement with basic ranking and form data.

For traders, the main catalysts are simple: whether the scheduled first-round match is played on time, whether either player is withdrawn before the session, and whether any court-order reshuffle changes the timing. The contract also has a non-standard settlement rule: if the match is cancelled, never played, tied, or delayed beyond seven days without a winner, it resolves 50-50, so late tournament disruption matters as much as the result itself.[11] In practice, the key watchpoint is the official National Bank Open order of play and any last-minute injury or withdrawal news, because those are what would move the contract faster than marginal opinion about match-up strength.[11]

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

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