If Ben Shelton wins the Shelton vs Tirante professional tennis match in the 2026 ATP Houston Quarterfinal after a ball has been played, then the market resolves to Yes.
Confidence: none
Model: claude-sonnet-4-6
Screened: 2026-04-03T08:05:42Z
Reasoning: Winning a Grand Slam in 2026 does not require winning the Houston Quarterfinal match, and winning the Houston Quarterfinal does not imply winning a Grand Slam. These are completely independent events.
