Global Wealth and Money Supply
Global net worth reached roughly 600 trillion dollars by early 2025, driven by rising real estate, equity markets, and corporate balance sheets. This figure includes household and corporate assets minus liabilities, and it is tracked by institutions such as the Credit Suisse Research Institute and McKinsey Global Institute. The broadest measure of money, M3, exceeds 100 trillion dollars worldwide, reflecting cash, deposits, and near-money instruments across economies. The United States, China, and Japan together account for more than half of this total, with the U.S. dollar still dominating global reserves. For a detailed breakdown of household wealth trends, see the Credit Suisse Global Wealth Report Global Wealth Report.
Money supply growth has accelerated in major economies since 2020, with central banks expanding balance sheets through asset purchases. The U.S. Federal Reserve, the European Central Bank, and the Bank of Japan collectively hold trillions of dollars in securities. This expansion has supported asset valuations but also raised concerns about inflation and purchasing power. The International Monetary Fund publishes quarterly data on broad money and reserve assets in its World Economic Outlook.

Top Companies and Market Capitalizations
The world's most valuable companies by market capitalization include Apple, Microsoft, Nvidia, Saudi Aramco, and Alphabet, with combined valuations exceeding 15 trillion dollars in 2025. Nvidia briefly became the first company to surpass 3 trillion dollars in market cap, driven by demand for AI chips and data center infrastructure. Apple and Microsoft remain above 2 trillion dollars each, supported by services revenue and cloud growth. These valuations are tracked daily by exchanges such as the NYSE and NASDAQ, and they fluctuate with earnings, interest rates, and macro conditions.

Private market valuations have also surged, with companies like SpaceX and OpenAI reaching multi-billion-dollar private valuations in secondary transactions and funding rounds. SpaceX is estimated to be worth over 350 billion dollars as of 2025, making it one of the most valuable private firms globally. These private valuations often exceed public comparables, though they are less liquid and less transparent. Investors track private market data through platforms such as PitchBook and CB Insights, which aggregate deal flow and secondary prices.

How Wealth Is Measured and Compared
Assets, Liabilities, and Net Worth
Wealth is calculated as total assets minus total liabilities, covering real estate, equities, bonds, business ownership, and cash. Global wealth inequality remains high, with the top 10 percent of adults holding more than 70 percent of total household wealth according to recent Credit Suisse data. The middle class in China and India has expanded rapidly, adding trillions to global net worth over the past decade. In contrast, many low-income countries carry high public and private debt, which depresses net worth relative to GDP.
