AI Reasoning: Search results and SEC 13F filings show Carl C. Icahn reported portfolio activity in 2025 (Q1 and Q2 filings and news articles). Examples: purchases/increases in Icahn Enterprises (IEP), CVR Energy, CVR Partners, and a reported acquisition of CVR Partners units in April 2025. The most recent reported activity is in Q2 2025 (filed Aug 2025) and transactions as late as September 2025 reports, which is within 6 months of the reference date.
