Vancouver: Maddison Inglis vs Mai Hontama

Platform comparison

Market context

Maddison Inglis and Mai Hontama met in Vancouver’s draw, and a **YES** share in this market means Inglis advances, while **NO** means Hontama advances. If the match is not completed in a way that produces a winner, the contract’s fallback rules can matter more than the scoreline itself: a cancellation, tie, or delay of more than seven days resolves to 50-50 rather than either player.[9]

The crowd-implied 100% YES price suggests the market is treating Inglis as a near-certain winner, but the history between the pair does not fully support that certainty. Hontama won their only recorded head-to-head meeting, a straight-sets win at the 2024 W50 Corroios-Seixal event, which is a reminder that one prior result can cut against a one-sided market price.[3][13] More broadly, Inglis has had the stronger recent win-loss record in the available summaries, while Hontama has also shown the ability to compete on hard courts, the surface relevant here.[1][6]

For traders, the main catalysts are simple: official match start time, any change to the order of play, and whether the contest is completed inside the settlement window. Tennis markets can move sharply on late withdrawals, walkovers, retirements, or schedule slippage, because those outcomes can determine whether a player advances or whether the contract falls back to 50-50 under the rules.[9] The listed match page also shows a projected winner tilt towards Inglis, but that is only a guide, not a settlement trigger.[9]

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 Market UK, 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.
