Mubadala Citi DC Open: Terence Atmane vs Alejandro Tabilo

Platform comparison

Market context

Polymarket’s contract is pricing **Terence Atmane at 28%** and **Alejandro Tabilo at 72%** on USDC-settled, Polygon-based conditional tokens, so the market is currently treating Tabilo as the clear favourite. For Polymarket users, the key mechanic is that settlement follows the official result of the Mubadala Citi DC Open meeting, but a non-played match, a tie, or a delay beyond seven days from the scheduled date would resolve 50-50 rather than to either player.

The number is broadly consistent with the pre-match shape of the market: Tabilo is the higher-ranked player, with ATP 30 versus Atmane’s ATP 56 in match listings, and Tennis.com projected Tabilo as the winner, while also showing a 42% chance for him in its preview model and 58% for Atmane on the same page, underlining that model-based estimates can vary materially by source.[14] Recent form data also leans Tabilo’s way, with one stats site showing Atmane on a poor run across recent matches and Tabilo carrying a stronger last-52-weeks record.[10] There is no head-to-head sample to anchor pricing, which usually leaves the market more sensitive to ranking, surface fit and current fitness than to direct history.[1][17]

For traders, the live catalysts are straightforward: official start times, any walkover or retirement update, and whether the match is actually completed before the settlement window closes on 2026-08-05T14:00:00Z. Because this contract resolves on whether Atmane advances against Tabilo, any scheduling change, suspension, or abandonment matters more than in a simple win-market, since a match that begins but is not completed can still be treated differently from one that never gets under way. The main practical check is the tournament’s order of play and the ATP/organiser scoreboard feed, since those determine whether the result becomes final or whether the 50-50 fallback is triggered.
