If Justin Rose finishes in the top 5 (including ties) in the 2026 The Masters, then the market resolves to Yes.
Confidence: none
Model: claude-sonnet-4-6
Screened: 2026-04-07T08:02:04Z
Reasoning: Finishing top 5 overall does not require finishing top 20 in round 1 (a player could have a poor round 1 and recover). Finishing top 20 in round 1 does not guarantee a top 5 finish overall. No logical necessity in either direction.
Strategy: Buy NO on antecedent + YES on consequent
