Larry Fink’s annual letter warns of profound global uncertainty, yet identifies one clear trend: the accelerating dominance of AI-enabled tech giants. A new McKinsey report dubs nine companies—including Alphabet, Amazon, and Apple—as omniscalers, set to control future growth markets from AI to space. These firms are not just winners; they are redefining economic scale through unparalleled investment.

Collectively, the omniscalers generated $2.7 trillion in 2025 revenue, exceeding Italy’s GDP. Their R&D and capital expenditure topped $800 billion, a staggering three times the revenue share of traditional industry firms. This spending fuels expansion into new sectors, exemplified by Jeff Bezos’s $100 billion AI fund and Elon Musk’s merged AI, auto, and space ventures.

Their financial power is systemic. In 2024, the six U.S.-based omniscalers produced $550 billion in operating cash flow—2.5 times all capital raised on US equity markets that year and nearly matching total bank lending to non-financials. Their internal capital markets dwarf many nations’, concentrating economic influence.

Outside China, regulatory appetite for curbing these national champions appears limited, despite histories of aggressive acquisition—Alphabet and Microsoft have each bought over 200 companies. While a recent ruling holds Google and Meta liable for child addiction, breakup remains unlikely. Their dominance faces risks from potential stock bubbles and disruptive AI from rivals like Anthropic. For investors, backing these omniscalers has yielded immense gains, but Fink’s core question persists: what of the widening inequality for those excluded from this winner-take-all economy?
