Mubadala Citi DC Open, Qualification: Andres Martin vs Moez Echargui

Platform comparison

Market context

Andres Martin has moved through qualifying as the stronger-priced side, and the live match data now appears to be the key change in the last 24–48 hours: one score source shows Martin leading Echargui 6-2, 7-5 in their qualifying round, which would make the market effectively settled if that result is confirmed.[3] Before that, pre-match projections also leaned Martin’s way, with Tennis.com listing him at 59% projected win probability and Tennis Tonic making him the pick to win, despite a relatively competitive price line.[1][4]

That framing matters because qualifying matches at ATP events can look tighter on paper than the market implies, but the crowd-implied 100% YES is consistent with a live or completed Martin advance rather than a truly open contest.[1][4] The main comparable case here is any qualifier where the favourite has already taken the first set and is closing out the second: once a scoreline like 6-2, 7-5 is in place, the remaining uncertainty is usually not on-court strength but whether the result is fully official for settlement purposes.[3]

The traders’ watchlist is therefore administrative rather than athletic: confirmation that the match result is final, whether any score feed updates overturn the current line, and whether the event record matches the market’s settlement rules for a completed contest versus a non-completion or walkover.[2][3] If the official draw or live ATP/WTA-style scoring feed shows Martin advancing, the 100% reading is hard to challenge; if instead the match were voided, delayed beyond the settlement rules, or never played, the outcome would depend on the market’s fallback language rather than the on-court favourite.[2]

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.
