The current Polymarket odds vividly illustrate the market's efficiency in pricing known information. Ben Shelton's price of 0.9995 (or 99.95%) reflects a near-unanimous expectation of his victory, which is entirely consistent with the confirmed match result.

Pre-Match Context and Expert Opinion:

Leading up to the match, Ben Shelton was considered the heavy favorite. He entered the US Open as the No. 8 seed and world No. 9, boasting a strong 2026 season with 35 wins and 13 losses, including four titles across different surfaces. His head-to-head record against Shapovalov also strongly favored him at 4-0 prior to this encounter.
