Billionaire activist investor Carl Icahn significantly reduced his firm's holding in American Electric Power (AEP) during the second quarter of 2026, cutting the position by nearly 64%. The sale involved approximately 771,000 shares, leaving a remaining stake of about 434,710 shares. This was one of only two major reductions Icahn made to his firm's portfolio during the quarter, suggesting a selective move to trim exposure rather than a broad reallocation of capital.
This trade information was made public in a mid-August 13F filing, which discloses holdings as of June 30, 2026. The filing confirms a transaction that occurred between April and June but does not specify the exact date or price. At the end of the second quarter, Icahn's remaining investment in the utility was valued at nearly $60 million.
