BlackRock Bottom Line

Wei Li

BlackRock Chief Investment Strategist

The world’s economies and markets are being transformed by mega forces, especially artificial intelligence. As we track this transformation into 2026, the three investment themes in our 2026 outlook are: one, Micro is macro; two, Leveraging up; and three, Diversification mirage.

First: Micro is macro. Companies’ capital spending ambitions tied to the AI buildout are huge - big enough to have a macroeconomic impact. The overall revenues that AI eventually generates could justify the spend at a macro level, but it’s unclear how much tech companies will capture. We think they’ll adjust plans as visibility on potential revenues and energy constraints improve.

Second: Leveraging up. AI spending comes first, benefits and revenues are likely to only come later. That creates a need for long-term financing – making greater leverage inevitable. We expect companies to keep tapping public and private credit markets, creating opportunities for investors.

Third: Diversification mirage. In markets driven by just a few forces, allocations made under the guise of diversification may now in fact be big active bets. Investors should be ready to pivot quickly. We think traditional diversifiers like long-term Treasuries will no longer be the reliable buffer they once were. We prefer exposures with their own sources of returns, such as private markets and hedge funds.

The bottom line is: we stay pro-risk and think the AI theme will remain a key driver of equity returns. We see an environment ripe for active investing.
_________________________________________________

Substantiation for opening line for theme 1 per L&C: External estimates of AI corporate capital spending ambitions range between U.S.$5-8 trillion globally through 2030, mostly in the U.S. This is based on data center deployment estimates (gigawatt terms) and capex per gigawatt assumptions reflecting cost inflation, GPU life, phasing and hyperscaler market share. We cross-referenced with other sources including McKinsey & Company, Boston Consulting Group, Lawrence Berkeley National Laboratory, International Energy Agency, U.S. Department of Energy, Bloomberg, NEF, Schneider Electric, Electric Power Research Institute and others.

Pushing limits

The global economy and financial markets are being transformed by mega forces, especially AI. With a handful of companies dominating the AI buildout, it’s hard to avoid making a big call on their direction. Wei Li, Global Chief Investment Strategist at BlackRock, outlines three key themes in our 2026 Global Outlook that help us navigate this.
