The US Stock Market Dominates the World, Surpassing Four Asian Countries

The United States stock market has once again set a historic milestone. According to data from Bloomberg and Deutsche Bank Research as of June 22, 2026, the total US stock market capitalization reached approximately US$81 trillion, or nearly 48% of the global stock market capitalization, which is valued at around US$167 trillion.

This figure shows an unprecedented dominance. The value of the American stock exchange is now larger than the combined stock markets of several major Asian countries such as China, Japan, Hong Kong, and Taiwan. 

In fact, the US stock market capitalization also surpasses the combined value of the next 18 largest stock exchanges in the world.

This phenomenon further strengthens Wall Street’s position as the center of the global capital market while demonstrating how American technology companies continue to be the main engine of world financial market growth.

Key Takeaways

• US stock market capitalization reached approximately US$81 trillion or nearly 48% of the total global stock market.
• The value of the American stock market is now larger than the combined stock markets of China, Japan, Hong Kong, and Taiwan.
• Wall Street’s dominance is driven by the growth of giant technology companies and massive investments in the artificial intelligence (AI) sector.

US Stock Market Capitalization Breaks World Record

The latest data shows that the US stock market is now at a very dominant level in modern history.

With a capitalization of around US$81 trillion, the United States controls nearly half the value of all publicly listed companies in the world’s stock exchanges.

For comparison:

• United States: approximately US$81 trillion
• China: approximately US$17 trillion
• Japan: approximately US$8 trillion
• Hong Kong: approximately US$6 trillion
• Taiwan: approximately US$4 trillion

This means the US stock market value is about 375% larger than China, which remains the world’s second-largest stock market.

Even more interestingly, Wall Street’s capitalization is larger than the combined value of those four major Asian stock markets.

Why is the US Stock Market So Dominant?

This dominance did not happen overnight. Several factors have made US stocks continue to attract global capital flows.

Trillion-Dollar Technology Companies

The biggest contributors come from the Magnificent Seven group, namely:

• Apple
• Microsoft
• Nvidia
• Amazon
• Alphabet (Google)
• Meta
• Tesla

These seven companies have become symbols of the global technology revolution, ranging from cloud computing, semiconductors, AI, electric vehicles, to digital platforms.

In fact, the combined value of the Magnificent Seven is now said to be larger than the entire stock market capitalization of China.

The AI Boom Becomes the New Driver

If the market rally since 2009 was driven by post-global financial crisis recovery, then from 2023 to 2026, the main driver has shifted to Artificial Intelligence (AI).

Investors are flocking to buy shares of companies involved in AI infrastructure development, such as:

• AI chip manufacturers,
• cloud providers,
• data center operators,
• electricity companies,
• communication network providers.

The Philadelphia Semiconductor Index (SOX), for example, recorded an extraordinary increase in the first half of 2026 due to high demand for AI chips.

This phenomenon strengthens the perception that America remains the center of world technology innovation.

Wall Street Becomes the Global Stock Market Benchmark

Wall Street’s dominance means that every movement in the US market almost always influences stock exchanges in various countries.

When indices such as the S&P 500, Nasdaq, or Dow Jones strengthen, global investors usually increase exposure to risk assets.

Conversely, if the US stock market experiences a sharp correction, the impact often spreads to:

• Asian stock markets,
• European stock markets,
• currency exchange rates,
• commodity prices,
• even crypto assets such as Bitcoin.

This is why developments in Wall Street news always receive attention from investors around the world.

The Longest Bull Market Supported by AI and Big Tech

The rise in the US stock market has actually been ongoing since the lowest point of the 2009 financial crisis.

Over more than one decade, the S&P 500 index has recorded an increase of more than 1,000% (excluding dividends).

In the early phase, the increase was driven by economic recovery.

However, in recent years, growth has mainly come from large-cap technology companies.

Nvidia is the most striking example. Initially known as a graphics card manufacturer, the company is now the leader in the AI chip industry and once became the world’s most valuable company.

Other companies such as Microsoft, Apple, Meta, and Amazon also continue to increase profits thanks to AI-based service expansion.

Will This Dominance Last?

Although the trend is still very strong, some analysts are starting to warn that the US market valuation is already at a high level.

Several risks that need attention include:

• increasingly expensive technology stock valuations,
• global economic slowdown,
• interest rate hikes,
• geopolitical uncertainty,
• potential slowdown in AI investment.

Nevertheless, many institutional investors still believe that American companies have competitive advantages that are difficult to match, especially in technology development and innovation.

Therefore, although short-term corrections may occur, US stock market dominance is expected to not change significantly in the near future.

What is the Impact on Indonesian Investors?

For Indonesian investors, this condition shows that global diversification is becoming increasingly important.

In addition to investing in the domestic market, some investors are starting to consider exposure to US stocks today through ETFs or international investment platforms.

However, investment decisions still need to consider each individual’s risk profile.

The dominance of the US stock market indeed reflects the strength of the country’s economy and technological innovation, but high valuations also mean potential volatility remains.

Investors should not only follow trends, but also understand the fundamentals of companies before buying stocks.
