If Rory McIlroy wins any of the four golf major tournaments (The Masters, the PGA Championship, the U.S. Open, and The Open Championship) in 2026, then the market resolves to Yes.
Confidence: high
Model: claude-sonnet-4-6
Screened: 2026-03-19T08:39:11Z
Reasoning: If McIlroy wins the Masters, he has won one of the four majors in 2026, so the major win market must resolve Yes. The reverse does not hold — he could win a different major.
Strategy: Buy NO on antecedent + YES on consequent
