AI, Capital, Cycles, and the Opportunity for Value Investors

First Quarter 2026 Commentary


Artificial intelligence is driving a significant shift in capital allocation and investor expectations across global markets, as large-scale investment is occurring alongside considerable uncertainty about how value will ultimately be created and captured. 

  • Three themes frame our perspective: 
  • The scale of current investment and its implication for future returns 
  • How markets are pricing disruption and the range of potential outcomes 
  • Where we are finding opportunities as value investors in response to these dynamics 

THE SCALE OF INVESTMENT 

The amount of capital now flowing into AI investment is extraordinary. Annual AI data center capital expenditures could reach approximately $1.4 trillion by the end of the decade, with cumulative investment measured in the trillions of dollars1. At the same time, roughly $20 trillion of market capitalization is now associated with AI-related companies, comparable to the size of entire developed equity markets such as Europe or Japan2.

The world is in the early stages of one of the largest capital investment waves in modern history. The scale alone demands scrutiny. 

A FAMILIAR PATTERN, WITH HIGHER STAKES 

Booms in capital spending have often historically been followed by overcapacity and disappointing returns. Energy (shale), memory semiconductors, and telecom infrastructure have repeatedly demonstrated this familiar pattern. Periods of large-scale technological investment have exhibited a similar dynamic. In the late 19th century, railroad construction absorbed a meaningful share of U.S. economic activity. The impact was substantial, lowering transportation costs and enabling national markets, and may have increased U.S. GDP by as much as 25%3. Yet investor outcomes were far less attractive, with many railroad companies entering bankruptcy following periods of overbuilding. 

A century later, the buildout of internet and telecom infrastructure again required substantial capital. While the technology proved transformative, many of the companies that financed and constructed it generated weak returns. The scale of investment and the magnitude of economic impact do not necessarily translate into attractive returns for investors, as highlighted by these cycles (see Exhibit 1). The benefits tend to accrue to end users, the broader economy, and scaled market leaders, rather than to the providers of capital.

Despite the scale of AI investment, the economic question remains unchanged: who ultimately earns an adequate return on this capital?

DISRUPTION AND THE RANGE OF OUTCOMES 

Markets appear to be pricing in both widespread disruption and broad displacement. In practice, outcomes are likely to be uneven. Scaled incumbents, including large banks, are often well positioned to capture efficiency gains given advantages in data, distribution, and capital. However, those gains are unlikely to remain proprietary, as competition erodes excess returns. 

AI is likely to act as a source of both efficiency and disruption, with results varying across companies. The pace of change adds to this uncertainty, as successive model improvements reshape perceptions of competitive advantage. The timing and shape of adoption also remain unclear. Current investment represents a forward bet on demand, but how quickly that demand materializes, and who captures it, is uncertain. Open-source models and global competition further increase the risk of commoditization. 

The result is a wide and asymmetric range of outcomes, reinforcing that dispersion is likely to occur at the company level. The potential paths for AI span a wide range of outcomes, not only for the economy, but also across industries and at the individual company level (see Exhibit 2).

WHAT WE DO AS VALUE INVESTORS IN LIGHT OF AI 

We do not claim to know the ultimate winners in AI. The scale of investment and uncertainty around adoption make that impossible at this stage. 

Importantly, we believe uncertainty creates opportunity. Markets tend to overreact when outcomes are unclear, and entire industries have seen sharp drawdowns as investors attempt to price AI disruption. Pricing long-duration and highly uncertain outcomes is difficult when narratives dominate near-term expectations, but that volatility can be fertile investment ground for long-term investors. 

DIRECT BENEFICIARIES 

We maintain selective exposure to areas with clearer demand visibility, where AI-related investment is already contributing to growth, including parts of the semiconductor ecosystem, cloud platforms, and infrastructure-related businesses. Examples include Samsung, TSMC, Alibaba, and suppliers such as Hon Hai and United Integrated Services. We also see second-order effects in energy, particularly in companies exposed to natural gas, such as Shell and Equinor. 

Importantly, our investment cases are not predicated on AI spending continuing indefinitely. In most cases, AI represents incremental upside rather than the core thesis of the business. Several of our positions have appreciated, as expectations have increased, and we have exited some as they approached our estimate of fair value. 

Our aggregate exposure to AI-related investments remains modest. Even within these areas, outcomes are unlikely to be uniform, and our focus remains on individual companies. 

BUSINESSES UNDER PRESSURE 

Compelling opportunities may also exist in companies perceived to be at risk from AI. Across several industries, valuations reflect an assumption that the profit pool will shift. Staffing, IT services, customer service outsourcing, and parts of the software industry are being repriced under the belief that AI will materially impair their economics. 

The key question is not whether AI will have an impact, but how that impact will be distributed across companies. 

STAFFING AND IT SERVICES 

The bear case for both staffing and IT services is similar: if AI reduces the need for labor, demand for intermediaries is expected to decline. However, current conditions reflect more than structural change. Staffing is still adjusting from post-COVID over-hiring, while IT spending is being delayed, as enterprises reassess deployment. Near-term weakness may be overstated as a long-term trend. 

Both industries have adapted to change historically. In staffing, uncertainty increases the value of flexibility, and, in IT services, greater technological capability increases implementation complexity. AI introduces similar dynamics. While some tasks become more efficient, deploying AI at scale remains complex, and most organizations lack the internal capabilities to manage this transition. 

Companies such as Randstad, Cognizant, and Accenture operate within this gap. While demand may evolve, it is not clear that it declines in a sustained way. Outcomes are likely to vary at the company level. 

CUSTOMER SERVICE 

Customer service outsourcing is often viewed as a clear casualty of AI. In practice, companies such as Teleperformance manage complex interactions across channels and geographies. AI may reduce simple interactions, but it also introduces new complexity in hybrid systems. 

The likely outcome is a shift in service mix rather than obsolescence. Current valuations appear to discount a more severe outcome. 

SOFTWARE 

Software presents a more nuanced case. AI may reduce development costs and lower barriers to entry, while enhancing the value of certain platforms. Outcomes are likely to be company-specific. We are examining the sector for opportunities, while remaining mindful of value traps. 

THE COMMON THREAD 

As markets attempt to price long-term structural change in real time, they may often overshoot, particularly in sectors perceived to be at risk. This creates opportunity. When valuations imply severe disruption, outcomes do not need to be perfect, only better than what is priced in.

POSITIONING FOR ASYMMETRY 

We believe the AI cycle is still in its early stages. Heavy investment, rapid change, and uncertain outcomes are likely to drive continued volatility. Rather than trying to identify future winners, we focus on situations where the balance of risk and reward is favorable. 

Our approach is to maintain humility and focus on asymmetry, investing where we believe downside is limited and upside is meaningful if outcomes are even modestly better than expected. 

CLOSING THOUGHT 

AI may prove to be highly transformative. But transformative technologies do not necessarily produce attractive investment returns. Our objective is not to predict the future with precision, but to identify where expectations and reality are most likely to diverge.
