Canadian Open, Qualification: Marco Trungelliti vs Nicolas Mejia

Platform comparison

Market context

Marco Trungelliti and Nicolás Mejía are scheduled to meet in Canadian Open qualifying on outdoor hard courts in Montréal, with the match listed for Court 9 at 14:30 UTC. At the time of the market snapshot, live score services show the contest has already started and is in the third set, which materially changes how a trader would script exposure: a pre-match 0% crowd-implied YES can be a stale print if the event is underway and the market has not repriced yet.[2][1][5]

For a tooling-first read, the useful baseline is ranking and surface context rather than headline form alone. Trungelliti is listed around ATP No. 91 and Mejía around ATP No. 131, and both have 0:0 head-to-head records on the listed comparison pages, so there is no established matchup edge to anchor an automated model.[2][11][18] In practical terms, copy-trading or conditional-order setups would usually key off live-score state, set count, and any retirement signal rather than the opening probability, because Canadian Open qualifying matches can flip from a normal completion path to a non-completion outcome quickly if there is a medical timeout, walkover, or abandonment.[5]

The main catalysts to watch are confirmation that the match is still active, any official schedule reshuffle from the tournament desk, and whether a suspension or retirement is reported before completion. Polymarket’s own rules here are explicit that a fully played match settles YES, while non-completion, walkovers, retirements, or a delay beyond the settlement window push it to NO or the market’s fallback treatment, so a programmatic monitor should track both the live state and the governing outcome logic rather than only the scoreline.[5][2]

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

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.
