The Mirage of Broad Market Gains
Passive indexing is dying. The era of buying the S&P 500 and sleeping soundly has been replaced by a fragmented reality where macro themes dictate the winners. BlackRock recently signaled this shift through Jay Jacobs on The Bid podcast. They are moving away from broad exposure toward specific silos. These include AI usage intensity and defense spending. Geopolitical fragmentation is no longer a tail risk. It is the primary driver of capital flows. When the world’s largest asset manager pivots its narrative toward thematic investing, it is an admission that the old guard of diversification is failing. The market is now a collection of specialized bets on energy constraints and sovereign security.
The Energy Wall and AI Intensity
AI is hitting a physical limit. We have moved past the software hype into the hardware reality. Data centers now consume a staggering percentage of global power. BlackRock identifies AI usage intensity as a core theme because compute power is the new oil. Investors are no longer just looking at chip designers like NVIDIA. They are looking at the electrical grid. According to Reuters energy reporting, the strain on aging infrastructure has created a bottleneck for scaling large language models. This is not a digital problem. It is a copper and transformer problem. The thematic approach seeks to capture the entire vertical. This includes the cooling systems and the nuclear small modular reactors (SMRs) powering the next generation of clusters.

Defense Spending as a Structural Constant
War is now a line item in every portfolio. Geopolitical fragmentation has forced a massive reallocation of sovereign wealth. The days of the peace dividend are over. Defense spending is no longer cyclical. It is structural. BlackRock’s emphasis on this theme reflects a world where supply chains are being weaponized. Nations are reshoring critical industries. This is inflationary by nature. As reported by Bloomberg Markets, the cost of securing trade routes has spiked since late 2025. Investors are chasing companies that provide autonomous defense systems and cybersecurity. The thematic play here is not just about kinetic warfare. It is about the digital and physical fortification of the nation-state. Capital is flowing toward the entities that can guarantee sovereignty in a fractured global order.
The Fragmentation of Global Liquidity
Liquidity is becoming localized. The globalized financial system is splitting into regional blocs. This fragmentation creates inefficiencies that thematic investors exploit. When BlackRock talks about themes defining market behavior, they are talking about the breakdown of the correlation between asset classes. In the past, everything moved with the dollar. Now, energy-rich regions are decoupling from traditional Western financial cycles. The thematic investor looks for the friction points. They bet on the companies that facilitate trade between these diverging blocs or provide the essential resources that cannot be easily substituted. This is a high-stakes game of identifying which themes will survive the next decade of deglobalization.
Estimated Thematic Returns vs Benchmark
| Investment Theme | Estimated YTD Return (%) | Volatility Index | Primary Driver |
|---|---|---|---|
| AI Infrastructure | 14.2 | High | Power Grid Demand |
| Defense Systems | 9.8 | Medium | Sovereign Contracts |
| Energy Storage | 11.5 | High | Lithium/Grid Tech |
| Cybersecurity | 7.4 | Low | Corporate Hardening |
| S&P 500 (Benchmark) | 3.1 | Medium | Broad Market Sentiment |
The Shift from Growth to Resilience
Resilience is the new growth. Investors are paying a premium for stability in an unstable world. This is why energy constraints are a central pillar of BlackRock’s current strategy. You cannot have a digital economy without a stable physical foundation. The thematic shift is a move toward the tangible. It is a move toward the things that cannot be printed or programmed. We are seeing a massive rotation into hard assets and the technology required to manage them. The focus on AI usage intensity is a proxy for productivity gains in a labor-constrained world. If a company cannot automate, it will not survive the wage-push inflation that characterizes this era. Thematic investing is the only way to filter for the survivors.
Watch the March 15 report on US power grid utilization. That data point will reveal if the AI infrastructure theme is overheating or just beginning its ascent. The gap between energy supply and compute demand is the most important metric for the remainder of the year.
