BlackRock 2026 Outlook: AI Infrastructure Investment of $5-8 Trillion to Reshape U.S. Stocks, Stablecoins as New Financial Infrastructure

[Block Rhythm] BlackRock’s latest 2026 Global Outlook report has attracted market attention. The report reveals several key logical points about this year’s market—first is the so-called “micro is macro” phenomenon.

What does it mean? It means AI development is now concentrated in the hands of a few tech giants, whose capital expenditures are large enough to influence the entire national economy. It is estimated that between 2025 and 2030, AI infrastructure investments could reach $5-8 trillion. This money supports U.S. economic growth, and BlackRock estimates its contribution to GDP growth is three times the historical average. Even if the labor market cools down, this scale of investment can maintain economic resilience. But here’s the question—can revenue keep up with such massive spending? Historically, over the past 150 years, technological revolutions have not broken the U.S. long-term 2% growth ceiling, but this time, it might truly be an exception.

The second risk is called “leverage increase.” AI builders have made huge upfront investments, but profits lag behind, leading to an overall increase in system leverage. Coupled with high government debt, vulnerability arises. BlackRock therefore tactically reduces long-term government bonds and favors private credit and infrastructure financing opportunities.

The third pitfall is the “diversification illusion.” Under the influence of major trends, seemingly diversified investment portfolios may actually be concentrated bets. Investors need to actively hold risk, stay flexible, and pay attention to the non-correlation returns of private markets and hedge funds.

Most interestingly, BlackRock redefines stablecoins and digital assets—not as speculative tools, but as infrastructure (plumbing) of the financial system. Stablecoins are seen as “digital dollar tracks,” evolving from native crypto tools into bridges connecting traditional finance and digital liquidity. In areas like cross-border payments and settlements—especially in regions where traditional systems are slow, expensive, and fragmented—the role of stablecoins is becoming prominent. This signals that crypto is integrating into mainstream finance, and building digital asset infrastructure is an inevitable trend.
