Who’s Managing the World’s Money, and Why It Matters
September 13, 2026—Here is a look at the world’s largest investment firms and a review of why their decisions matter to populations everywhere.
A Trillion Dollar Industry Defined
Private asset management (AUM) is a multi-trillion dollar industry. It impacts decisions on investments and money flows. Asset management (AUM) includes mutual funds, ETFs, hedge funds and other structured funds managed by investment firms. Two of the largest firms, BlackRock and Vanguard, account for a combined $25 trillion. Here’s the top ten.
Private Decisions, Public Outcomes
In the global economic system, private markets determine priorities. In effect, they decide which products to develop, which regions deserve capital, and how money flows from savings to investment.
Asset management firms, in particular, govern decisions over a significant amount of the world’s financial resources. They actively manage the savings of millions of individuals and institutions, putting them into stocks, bonds, funds, and digital assets. In terms of size, the top 500 asset management firms oversee $140 trillion in financial resources.₁ By some estimates, that accounts for roughly half of the world’s private financial assets.₂ ₃ Consequently, asset managers wield significant influence in the global economy.
Public Interest
It’s relevant for policy in more ways than one. For public officials aiming to solve global issues like climate action and managing AI, private capital matters a lot. How investment firms allocate their money matters. Policymakers have numerous tools, such as tax and spending decisions, to influence the money flows. For example, when JP Morgan Chairman and CEO Jamie Dimon warned of risks of geopolitical tensions, economic shocks, “stickier inflation,” and interest rates in April, many policymakers took note. He cited risks to private credit markets, particularly to highly indebted companies, due to weaker lending standards. Dimon has been particularly keen on developing a model for stakeholder capitalism, which calls on corporations to take a stake in investing in local communities and play a positive role in society.
Inclusive Capitalism
More importantly, it matters to inclusive capitalism, ensuring that decisions by the most influential decision-makers work for the broader population. The largest investment firms have enormous impact on capital itself but also on corporate decisions of the companies in their portfolios.
The decisions they make affect corporate governance, executive pay, and social responsibility. Firms also have substantial say over public policy decisions. Executives from top firms often serve on government advisory boards. Many move back and forth between Wall Street and Washington, taking on Cabinet positions. Asset management firms are not the top lobbyists in Washington, but they pour substantial money into Capitol Hill.
Looking Back
When the GER looked at the largest firms in 2022, we included firms with quasi-government ownership. Here’s how the results stacked up then. Notably, the largest ten asset management firms oversee $38 trillion in investments. Two of the top 10 largest are headquartered in China.
In 2021, asset management by the world’s top 500 firms grew to nearly $120 trillion, according to the nonprofit Thinking Ahead Institute. The following year, the growth subsided due to declines in the dollar value of equity markets.
