What are the largest stock exchanges in the world?

There are dozens of major stock exchanges globally, ranging in size and trading volume from the New York Stock Exchange to tiny local exchanges. Here we take a look at the largest stock exchanges in the world by market capitalisation.

What is a stock exchange?

A stock exchange is a marketplace for the buying and selling of shares, bonds and securities. Stock exchanges can serve as a measure of the health of the national economy and also be a key indicator of global economic strength. This is because the growth of the financial market is associated with higher living standards and higher employment rates.

Traditionally, stock exchanges were physical buildings in each country of operation, but with the shift toward electronic trading, many have closed their trading floors and switched to online platforms.

However, the institutions themselves are still around, and some are bigger than ever, with market capitalisations of trillions of dollars.

New York Stock Exchange – approx. $30.9tn
 

The New York Stock Exchange (NYSE) is the largest stock exchange in the world by market capitalisation.

Its origins trace back to the Buttonwood Agreement of 1792, with formal organisation in 1817 and its modern name adopted in 1863. Today, it is owned by Intercontinental Exchange (ICE).

The NYSE operates a hybrid trading model, combining electronic systems with designated market makers on a physical trading floor in New York. It lists over 2,000 companies, including many long-established multinational firms.

Companies listed on the NYSE span sectors such as finance, healthcare, energy, and consumer goods, and tend to include more mature, dividend-paying firms than some other exchanges.

Its listed companies are commonly tracked by indices such as the S&P 500 and the Dow Jones Industrial Average, which are widely used as benchmarks for US and global equity performance.
 

NASDAQ – approx. $30.4tn
 

The Nasdaq Stock Market is the second-largest exchange globally and was the world’s first fully electronic stock market, launched in 1971.

Unlike the NYSE, Nasdaq does not have a traditional trading floor and operates entirely through electronic systems. It is particularly associated with technology, biotechnology and high-growth companies, and has a higher concentration of growth-oriented stocks.

The exchange is tracked by two key indices:

• The Nasdaq-100, which includes large non-financial companies

• The Nasdaq Composite, which tracks nearly all listed securities

Nasdaq also plays a major role in global listings and capital raising, particularly for technology firms.

 

Shanghai Stock Exchange – approx. $8.0tn

 

The Shanghai Stock Exchange (SSE) is one of the largest stock exchanges in Asia and a core part of China’s financial system.

The modern exchange was re-established in 1990, although Shanghai had an active securities market in the late 19th and early 20th centuries.

The SSE lists mainland Chinese companies primarily and trades shares in renminbi (yuan). It operates different share classes, including:

• A-shares, mainly available to domestic investors

• B-shares, which are accessible to foreign investors

International access has expanded through schemes such as the Shanghai–Hong Kong Stock Connect, allowing foreign investors to trade selected mainland-listed shares.

The exchange is tracked by the SSE Composite Index, which reflects the performance of all listed stocks.

 

Tokyo Stock Exchange – approx. $6.7tn

 

The Japan Exchange Group (JPX) operates the Tokyo Stock Exchange (TSE), Japan's largest stock exchange.

Founded in 1878 and reopened in 1949, the TSE merged with the Osaka Securities Exchange in 2013 to form JPX.

The exchange is divided into different market segments (such as Prime, Standard and Growth), which classify companies based on size, liquidity and governance standards.

The TSE lists thousands of companies across key industries such as automotive, electronics, manufacturing and financial services.

Its main benchmark, the Nikkei 225, is one of the most widely followed indices in Asia, alongside the broader TOPIX index, which tracks all companies in the Prime market.

 

Hong Kong Stock Exchange – approx. $5.7tn

 

The Hong Kong Exchanges and Clearing (HKEX) is a major global financial centre that connects Chinese markets with international capital.

Founded in 1891, the exchange has evolved into a fully electronic market, with its physical trading floor closing in 2017.

HKEX is known for listing both Hong Kong-based and mainland Chinese companies, including many large state-owned enterprises and technology firms.

It plays a key role in cross-border investment through Stock Connect programmes, which allow investors in mainland China and Hong Kong to trade eligible shares in each other’s markets.

The exchange’s main benchmark is the Hang Seng Index, which tracks leading companies listed on the Hong Kong Stock Exchange.

 

Euronext – approx. $5.6tn

 

Euronext is the largest stock exchange group in Europe, operating markets across multiple countries including France, the Netherlands, Italy, Ireland, Belgium and Portugal.

Founded in 2000, Euronext was created to integrate several national exchanges into a unified European marketplace.

It operates a single trading platform that allows investors to access multiple European markets through a single system.

Euronext lists a wide range of companies, from large multinational corporations to smaller domestic firms, and is tracked by indices such as the Euronext 100 and various country-specific indices (e.g. CAC 40).

 

Shenzhen Stock Exchange – approx. $5.1tn

 

The Shenzhen Stock Exchange (SZSE) is one of China’s main exchanges and is particularly focused on high-growth, technology and innovation-driven companies.

Founded in 1990, it complements the Shanghai Stock Exchange by providing a platform for smaller and more growth-oriented firms.

The SZSE includes specialised boards such as:

• SME Board (small and medium-sized enterprises)

• ChiNext, which supports start-ups and technology companies

Like Shanghai, foreign access to certain Shenzhen-listed shares is available through the Shenzhen–Hong Kong Stock Connect.

 

BSE India – approx. $5.3tn

 

The Bombay Stock Exchange (BSE) is one of the oldest stock exchanges in the world, established in 1875.

It is a central part of India’s capital markets and has seen significant growth in market capitalisation in recent years, reflecting the expansion of India’s economy and equity participation.

The BSE lists thousands of companies and is tracked by its benchmark index, the SENSEX, which comprises 30 large, established Indian companies.

The exchange also supports trading in equities, derivatives, mutual funds and debt instruments.

 

National Stock Exchange of India – approx. $4.8tn

 

The National Stock Exchange of India (NSE) is one of the largest exchanges in emerging markets, known for its high trading volumes and advanced technology.

Incorporated in 1992 and launched in 1994, it introduced fully electronic trading to India, replacing older open-outcry systems.

The NSE is a leader in derivatives trading, particularly index futures and options.

Its flagship benchmark is the NIFTY 50 index, which tracks leading Indian companies across sectors such as banking, IT and energy.

 

TMX Group (Canada) – approx. $4.0tn

 

The TMX Group operates Canada’s main stock exchanges, including the Toronto Stock Exchange (TSX) and TSX Venture Exchange.

The TSX is one of the largest exchanges globally and is particularly important for sectors such as natural resources, mining, oil and gas, and financial services.

Canada is a global hub for mining and energy companies, and many international firms choose to list on the TSX to access capital.

The exchange is tracked by indices such as the S&P/TSX Composite Index, which reflects the performance of the Canadian equity market.
