Granby: Aleksandar Vukic vs Liam Broady

Platform comparison

Market context

Aleksandar Vukic and Liam Broady are scheduled to meet in the opening round of the Granby tournament on 13 July 2026. The current crowd-implied probability of 100% for Vukic's advancement reflects either extremely high confidence in the Australian's form or minimal trading liquidity at this early stage. With settlement seven days after the scheduled match date, the market allows for minor delays but requires a definitive winner to avoid a 50-50 split resolution.

Vukic has competed regularly on the ATP and Challenger circuits, whilst Broady, a British player, has oscillated between ATP and lower-tier competition. Head-to-head records and recent form comparisons are essential anchors here. The 100% probability suggests traders may be pricing in either a substantial ranking or recent-performance gap between the two, or simply reflecting that early-stage tennis markets often lack depth. Sportsbook lines, where available, typically offer more granular odds; any meaningful divergence between the 100% implied probability and conventional bookmaker spreads would indicate either mispricing or information asymmetry worth investigating.

Key variables to monitor include official tournament draw confirmation, injury announcements, and any weather-related scheduling changes in the days before 13 July. Court surface conditions at Granby and recent match results from both players in the preceding weeks will inform whether the current probability holds. If either player withdraws or the match is postponed beyond 20 July without completion, the market resolves to a 50-50 tie, making withdrawal risk a material consideration for traders holding positions.

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

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

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Best Prediction Markets. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.
