Stock Exchange Market Cap: US vs World

The United States hosts the two largest stock exchanges on Earth by a staggering margin. The NYSE ($33.2T) and NASDAQ ($35.8T) together represent more market capitalization than the next five exchanges combined. American exchanges don't just lead: they dominate.

The S&P 500: The World's Benchmark

No index is watched more closely. No index is replicated more widely. The S&P 500 tracks the 500 largest publicly traded US companies, and its performance is the world's de facto report card on capitalist prosperity. Since 1980, it has delivered total returns exceeding 9,000%.

The Price of American Technology

If the S&P 500 is the scorecard of American capitalism, the Nasdaq is the scorecard of American technology: the exchange where Apple, Microsoft, NVIDIA, Alphabet, Amazon and Meta all list. The index opened at 100 in 1971 and now sits around 26,000, roughly 261 times higher. But the line is not a smooth ascent, and that is the point: it fell to 58.6 in the 1974 bear market, and after the dot-com peak in March 2000 it lost roughly three-quarters of its value and did not regain that level until 2015. The logarithmic scale is the default because it is the only one where the first thirty years are visible at all: switch to linear and you will see why.

The Fear Index

The VIX measures how much turbulence the market expects over the next 30 days. In quiet years it sits around 15. In moments of panic it detonates: 80.86 in November 2008, and 82.69 on 16 March 2020, the all-time record. The chart below shows exactly where confidence broke, every time since 1990.

The Market Against the Economy

Warren Buffett called this ratio "probably the best single measure of where valuations stand at any given moment": the total value of American equities divided by GDP. For most of the twentieth century the market was worth less than the country's annual output. Today it is worth more than twice as much.

The Price of Money

Every price on this page is ultimately quoted against a single one: the rate at which the Federal Reserve lends money overnight. In June 1981 Paul Volcker took it to 19.10% and deliberately caused a recession to break the inflation of the 1970s. In April 2020 it fell to 0.05%, about as close to free as money has ever been. The distance between those two moments is modern American financial history.

The Market's Recession Alarm

Normally long money costs more than short money. When that inverts (when the 10-year Treasury pays less than the 2-year), the market is betting rates must come down, which usually means it expects trouble. Every recession since 1976 was preceded by an inversion. The reverse does not hold: the 2022–24 inversion was the deepest since Volcker, and no recession followed. It is a good alarm that sometimes cries wolf.

What the Market Is Buying

Every valuation on this page is ultimately a claim on this number. American corporations earned $22 billion after tax in 1947. They now earn close to $4 trillion a year. A caution worth stating plainly: this is measured in the dollars of each year, so a real share of that rise is inflation rather than earning power. The shape is still the point: profits recover from every crisis on the chart, including the two that were supposed to end them.

The US Bond Market: $50.5 Trillion

With $50.5 trillion in outstanding fixed income securities, the US bond market is the largest and most liquid in human history. US Treasuries ($30.8T) set the global risk-free rate, the anchor for every financial model on Earth. Corporate bonds ($11.7T) hit record issuance in 2025 as American companies tapped cheap capital to fund AI infrastructure and global expansion.

Corporate Bond Yields: Moody's Aaa vs. Baa

Corporate yields measure the interest rates that prime American companies pay to borrow in fixed income markets. Moody's Seasoned Corporate Yields compare high-grade issuers (Aaa) with medium-grade issuers (Baa). The spread between them represents the credit risk premium, illustrating the continuous availability of debt capital to fund physical capital and R&D projects.

America's Major Exchanges

The US Treasury: The World's Risk-Free Anchor

Every financial model on Earth starts with the US Treasury yield. From 6% highs in the dot-com era, to 0.89% in 2020's ZIRP experiment, to 4.35% in 2025 following the fastest rate-hiking cycle in 40 years. No other bond market has the same depth, liquidity, or global relevance. The 10-year yield is, literally, the price of money for the world.

The Alternative Markets: America's Private Capital Giants

Beyond public equities, the US dominates global alternative assets. Blackstone ($1.3T), KKR ($744B), and Apollo ($650B) are the top three. These firms control private equity, private credit, infrastructure, and real estate funds at an unprecedented scale: 8 of the world's top 10 alternative asset managers are American.

The Fed Balance Sheet: The Liquidity Foundation

The total assets held by the Federal Reserve represent the ultimate liquidity foundation of the global financial system. Growing from under $1 trillion before the 2008 Financial Crisis, the balance sheet expanded through successive Quantitative Easing (QE) programs to support the economy during shocks, peaking near $9 trillion during the COVID-19 pandemic before transitioning into Quantitative Tightening (QT), ending at $6.7 trillion in 2026.

M2 Money Supply: The Capital Engine's Fuel

M2 measures the total money supply in circulation, including currency, demand deposits, and savings accounts. It represents the liquid purchasing power of the U.S. economy. The post-2020 monetary expansion drove M2 to over $23 trillion in 2026, illustrating the sheer volume of liquidity circulating through and backing the American capital markets.

Fed Funds vs. Inflation: The Battle Over Prices

The Federal Reserve uses the Federal Funds Rate as its primary tool to anchor inflation. The chart below traces this historical relationship over more than 50 years: from the aggressive rate increases in 1980 (Volcker pushing rates to 19% to tame 14% inflation), to the zero-lower-bound experiments of the 2010s, and the rapid tightening cycle in 2022–2024 to crush post-pandemic price pressures.

High-Yield Spreads: Corporate Credit Risk Barometer

The ICE BofA High Yield Option-Adjusted Spread measures the yield premium investors demand to hold lower-rated corporate debt (junk bonds) instead of risk-free Treasuries. Spikes in this spread trace the history of capital market stress: the dot-com bubble collapse (2002), the 2008 Lehman crisis, and the 2020 pandemic market freeze.

The Shiller CAPE Multiple: S&P 500 Historical Valuation

The Shiller CAPE (Cyclically Adjusted Price-to-Earnings) Ratio adjusts earnings for inflation over a 10-year period to smooth out business cycle noise. Values above the historical average of 17x signal elevated valuations. The chart maps historical peaks of optimism (such as the 44x dot-com bubble in 2000) and bottoms of panic (such as the 13x GFC trough in 2009). In 2026, the CAPE sits at 36.8x, reflecting high market valuations led by tech giants.

Nation's Balance Sheet: U.S. Household Net Worth

U.S. Household Net Worth represents the total assets of all American households (real estate, equities, pension funds) minus liabilities. Over the last 50 years, this figure has seen an unprecedented expansion, climbing to a record $182.9 Trillion in 2026. This enormous private capital pool is the fundamental engine of domestic demand and the largest store of private wealth in human history.
