Activist Investors Accelerate Global Actions: The Capital Logic and Industrial Restructuring Behind the Surge in M&A Demands in the First Half of 2026

Global Wave of Activist Investing: Paradigm Shift from "Fix" to "Sell"

In the second quarter of 2026, the activity of global activist investors surged sharply. According to Barclays data, a total of 136 public campaigns were launched globally in the first half of the year, an increase of 5% compared to the same period in 2025. Although this number is lower than the peak of 256 campaigns in the full year of 2025, the 74 campaigns in the second quarter mark a sharp rebound from the wait-and-see stance at the beginning of the year. Notably, there is a structural shift in investors' core demands: calls for target companies to sell assets or undergo full M&A have jumped from 14% in 2022 to 21%, becoming the most common catalyst.

The "Gravitational Field" of the US Market: Regulatory Dividends and Valuation Discounts

Geographically, the US market absorbed 68 campaigns globally in the first half of the year, accounting for half of the total, with a year-on-year increase of 13%. Multiple factors underlie this concentration: First, the continued deregulatory stance of the Trump administration has significantly reduced uncertainty in M&A approvals. Compared to the EU's Foreign Subsidies Regulation and China's strengthened antitrust enforcement, the US policy environment is more favorable for transactions. Second, valuation divergence is pronounced across US energy, technology, and industrial companies—for example, traditional energy companies like shale oil producer Devon Energy are undervalued, while AI software firms like Dynatrace face pressure from technological disruption. This allows activist investors to seek arbitrage and restructuring opportunities across different sectors.

AI and Industrial Restructuring: Tech Disruption Catalyzes Capital Action

More than half of global campaigns have targeted technology and industrial companies. Jim Rossman, global head of shareholder advisory at Barclays, noted that investors believe these sectors are most susceptible to AI disruption. This is not simply "tech stock hype" but capital identifying which companies' business models may be reshaped or phased out by AI. For example, Starboard Value's stake in Dynatrace is clearly not a pure financial investment; rather, it aims to push the company toward strategic adjustments or acquisitions to dominate the AI operations monitoring market. Similarly, TOMS Capital's pressure on Devon Energy reflects investors' revaluation of traditional fossil fuel assets against the dual backdrop of the energy transition and AI computing power demands.

The "Suction Effect" of the M&A Market: Where Global Capital Flows

Activist investors' appetite for M&A is not an isolated phenomenon.The appetite of activist investors for M&A is not an isolated phenomenon. In the first half of 2026, global M&A transaction volumes have rebounded to pre-pandemic levels, and the reopening of the IPO window in U.S. capital markets has provided an exit path. When investors demand "selling the company" rather than "fixing operations," they are essentially betting that the target asset cannot generate sufficient returns independently in the current cycle. This logic is particularly pronounced in the oil and gas, chemicals (e.g., Ashland), and payment services (e.g., Fiserv) sectors. From the perspective of global capital flows, the "caveat emptor" environment in the United States makes it the most liquid market for asset turnover, while regulatory barriers in Europe and Asia may force capital to shift toward more flexible jurisdictions. For instance, Middle Eastern sovereign wealth funds and Southeast Asian family offices are accelerating their asset allocation in the U.S.
