As we kick off 2026, activist investor campaigns are no longer just prevalent; they are global, sophisticated, and have increasingly become an acute threat to corporate leadership.

The escalating pressure is undeniable: Barclays data shows that activist investor campaigns hit a high last year – surpassing 2024 by 5% – with 32 CEOs resigning as a result (a record) – and showing no signs of slowing down. The number of public campaigns continues to grow significantly, with Goldman Sachs’s 2026 Outlook anticipating a new five-year high by the end of 2026.

And this doesn’t include the private campaigns – born in the Board room, remaining there, and rapidly leading to changes at the board and management level. These campaigns are also getting broader, according to Conference Board research, which points to a sustained expansion beyond traditional value-driven targets and increasingly centered around topical social issues like diversity, climate and beyond.

Activism thrives on corporate uncertainty and increasingly leverages a fast-changing media environment to exert pressure. According to the Goldman Outlook, features of recent campaigns – from impatience with internal “self-help” plans to intense scrutiny of capital allocation – place leadership, including CEOs, CFOs and Boards, directly in the crosshairs.
