The Polymarket prediction market concerning the US Open ATP third-round match between Tomas Etcheverry and Mariano Navone, originally slated for September 4, 2026, at 11:00 AM ET, has seen significant trading volume totaling $729,473. The market's current prices reflect an almost unanimous expectation of a Tomas Etcheverry victory, with his outcome trading at 0.9995, while Mariano Navone's stands at a mere 0.0005.

This extreme skew in probabilities signals a near-certain outcome in favor of Etcheverry. However, a review of recent news and schedules for the 2026 US Open presents a conflicting picture regarding the actual status of the match. While multiple sources, including 365Scores and Flashscore, had previewed the Etcheverry vs. Navone encounter as a third-round fixture scheduled for September 4, 2026, a report from TNT Sports on the same date listed the match as "Not started".

Both players were actively competing in earlier rounds of the tournament. Mariano Navone notably made headlines by defeating Novak Djokovic in the first round and subsequently overcoming Matteo Berrettini in the second round. Tomas Etcheverry also advanced, winning his second-round match against Jacob Fearnley. Their progression set the stage for their anticipated third-round clash.

The Polymarket's resolution rules state that if the match is canceled or a winner is not determined by September 18, 2026, the market will resolve to 50-50. Crucially, the rules also specify that "If the match ends in a walkover (player withdraws before the start and the other advances automatically), this market will resolve to 50-50." The current market price, heavily favoring Etcheverry, appears to contradict the walkover clause if the match indeed did not start and Navone withdrew. If Navone had retired during the match, Etcheverry would advance, aligning with the high probability. However, the "Not started" status complicates this interpretation.

The implied certainty of Etcheverry's advancement by the market suggests one of several scenarios: either the match was played and Etcheverry won definitively, or Navone retired during the match allowing Etcheverry to advance, or there is specific information available to market participants indicating Etcheverry's progression that falls outside the stated 'walkover' condition for a 50-50 resolution. Given the discrepancy between the market odds and the "Not started" status for the scheduled match, traders are clearly operating on strong conviction that Etcheverry has secured his spot in the next round of the US Open, potentially due to a development not yet widely reported or a specific interpretation of the advancement criteria by the official resolution source.
