The S&P 500 makes up 51% of global stock market value

As of December 31, 2023, U.S.-listed companies dominated global equity markets, accounting for 59% of the market capitalization, with the S&P 500 representing 51%.

The U.S. holds a substantial share, with the largest companies such as Apple, Nvidia, Microsoft, Alphabet, Amazon, and Meta making up most of the trillion-dollar firms.

Outside the U.S., developed markets excluding the U.S. contribute 30% of global equity, led by Japan, the UK, Canada, France, and Switzerland.

China represents 3%, while emerging markets, including countries like India, Taiwan, Brazil, and Saudi Arabia, make up 8%. China's economic significance justifies its separate listing, despite being classified as an emerging market.
