Rules
If Ben Shelton wins the Shelton vs Zhang professional tennis match in the 2026 ATP Houston Round Of 16 after a ball has been played, then the market resolves to Yes.
Confidence: none
Model: claude-sonnet-4-6
Screened: 2026-04-01T08:15:40Z
Reasoning: Winning a Grand Slam in 2026 does not require winning a Round of 16 match at the Houston ATP event, and winning that Houston R16 match does not imply winning a Grand Slam. These are entirely separate tournaments with no logical dependency.
Strategy: Buy NO on antecedent + YES on consequent
