AI, Cyber, and Market Capital Reallocation

Europe enters 2026 in the midst of the most significant capital reallocation since the creation of the single market. The beneficiaries are no longer consumer brands or low-cost exporters. These are the companies that own the hard infrastructure of the digital economy: computing, power, security, and industrial software.

This shift is already showing up in revenues, order books and stock prices across European markets, with data center suppliers, grid operators and cybersecurity companies outperforming many broader indexes over the past year.

AI infrastructure: Europe’s fastest-growing capital market

The strongest investment thesis in Europe is no longer apps and platforms, but AI infrastructure.

In 2024 and 2025, European data center investment grew at the fastest pace in more than a decade, driven by hyperscalers competing for capacity for generative AI. Frankfurt overtook London as Europe's biggest data center hub, while Paris, Dublin and Amsterdam all saw record leasing volumes.

Corporate winners are becoming clear.
Siemens Energy, which supplies power management and grid stabilization systems used in hyperscale data centers, has seen orders surge over the past year as AI-related demand replaces collapsing wind turbine sales.
Schneider Electric, Europe's leading supplier of data center electrical systems and cooling software, reported double-digit growth in its digital infrastructure sector as the cloud provider expanded its footprint in Europe.
Swiss-Swedish engineering group ABB is benefiting from a wave of spending on automation, high-voltage equipment and industrial robots needed to build and operate AI-grade facilities.

European real estate groups are also caught up in the boom.
SEGRO, Vantage, Digital Realty, and Equinix are expanding their European campuses, and infrastructure funds like Brookfield and Blackstone are pouring billions into AI-enabled sites in Germany, France, and Scandinavia.

Compared to a year ago, when European tech stocks were still dominated by consumer platforms and e-commerce, capital is now rotating to companies that own the physical backbone of AI, a structural shift that is reshaping European business.

Energy becomes the gatekeeper of the AI economy

What will change most after 2025 is not the demand for AI, but the price of electricity and access to the grid.

In Germany and the Netherlands, developers are now being told to wait years for new data center connections, forcing hyperscalers to compete for scarce power. This has made European power companies and grid operators some of the most powerful players in the digital economy.

Companies such as E.ON, RWE, National Grid, and Iberdrola have entered into long-term power purchase agreements with data center operators, securing a stable revenue stream that did not exist two years ago.
Meanwhile, Ørsted, Statkraft and Vattenfall sell renewable power directly to cloud operators, effectively turning wind and hydro projects into AI infrastructure.

In 2024, most renewable projects were priced as volatile commodity assets. By 2026, these companies will be valued similarly to long-term contract utilities, leading to a major revaluation within the European energy sector.

Cybersecurity becomes a hidden defense expense

The second major change from last year is that cybersecurity has become national security spending.

In 2024, cyber budgets were still treated as discretionary IT. In 2026, these budgets will be incorporated into defense, infrastructure, and critical services budgets, making revenues much more predictable.

European companies such as Darktrace, WithSecure, Thales and Atos' cybersecurity division benefit from multi-year contracts with governments, utilities and transport operators. Meanwhile, major U.S. companies such as Palo Alto Networks, CrowdStrike and Zscaler are aggressively expanding in Europe as regulators force companies to meet strict resilience standards.

Compared to a year ago, when cybersecurity was still a volatile technology trade, it is now priced more like regulated infrastructure and has gained weight within the European technology market.

How the market is reassessing Europe

These forces, such as AI, energy, and cyber, are currently dominating market performance.

Over the past year, European defense and infrastructure stocks have significantly outperformed consumer and retail stocks. Companies involved in data centers, grid equipment and digital security have seen improved profits, while consumer companies have struggled with inflation and slowing demand.

This marks a decisive break from 2023-24, when the European market was primarily driven by luxury goods, travel and consumer technology.

By 2026, strategic infrastructure will take over.

Investors are no longer asking whether Europe can compete with Silicon Valley. They are asking who controls Europe's power, computing and security.

That question now defines the European market.
