Canadian Open: Daniel Merida Aguilar vs Liam Draxl

Platform comparison

Market context

Polymarket is pricing this Canadian Open match as a near certainty for **Daniel Merida Aguilar**, with the contract sitting at a **100% YES** crowd-implied probability for his side. On Polymarket, the trade settles in USDC on Polygon via conditional tokens, so the relevant question is not who has the better tennis pedigree in the abstract, but whether Merida Aguilar advances against Liam Draxl before the settlement window closes.

That reading is broadly consistent with outside pre-match pricing, though not quite to the extreme implied by the market. Multiple sportsbook screens have had Merida Aguilar installed as the favourite, with moneyline quotes around 1.6-1.7 versus Draxl around 2.1-2.4, while model-based previews also lean towards Merida. The pair have no recorded head-to-head, which means there is less historical signal to anchor the price than in a repeat matchup, and that leaves the market more exposed to venue, surface, and draw-context assumptions than direct matchup history.

For traders, the key catalysts are simple: official ATP or tournament schedule updates, any late injury or withdrawal news, and whether the match is actually staged inside the original window. The market rules matter as much as the result, because cancellation, a tie, or a delay beyond seven days from the scheduled date without a winner push it to 50-50, while a started-but-unfinished match depends on the eventual official outcome. Current listings place the match on 3 August 2026, but any rescheduling, walkover, or retirement would materially change how the token resolves.

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.
