Activity by activist hedge funds, both in the U.S. and abroad, has increased since the end of the pandemic. In 2024, there was a slight increase in global activism campaigns compared to 2023, which saw a 9% increase in the number of campaigns compared to 2022.

There has also been a proliferation of first-time activists in recent years.
