Lexington: James McCabe vs Dusan Lajovic

Platform comparison

Market context

Polymarket is pricing this Lexington tennis contract at **0% YES** today, which means traders are effectively saying James McCabe is not expected to advance against Dusan Lajovic. The market settles through USDC on Polygon via conditional tokens, so the relevant question is not just who looks stronger on paper, but whether the match is played and completed within the market’s settlement window.

That near-zero price is hard to reconcile with the wider betting board, which shows McCabe as a modest favourite rather than a clear outsider. Sportsbet had McCabe at 1.76 and Lajovic at 2.02, while other price-comparison feeds put McCabe around 1.71, implying roughly a mid-50s win chance for McCabe and a similar split elsewhere. That is a meaningful gap versus a 0% YES quote, so the contract is trading as if either the outcome is already effectively decided in the market, or the event is expected to fail to resolve normally.

For traders, the key catalysts are the tournament’s official schedule, any walkover or retirement updates, and whether the match actually starts and finishes on time. Flashscore and SofaScore list the contest for 4 August in Lexington, and sportsbook prices were still live close to the event, so late injury, withdrawal, or rescheduling news could matter more than pre-match form. Because the market resolves 50-50 if the match is cancelled, tied, or delayed beyond seven days without a winner, the on-chain payoff can hinge as much on tournament administration as on who wins the court battle.

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 Polymarket Scam?, which mirrors the Polymarket order book directly.

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.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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.

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.

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.
