Stock markets are at the heart of the global economy, powering businesses and shaping wealth in 2025. From New York’s Wall Street to Mumbai’s financial hubs, these markets are where companies and investors meet. But what is a stock market, how many are there, and which ones lead the world? In this explainer, The Interview Times breaks down the basics of stock markets, counts the major exchanges worldwide, and lists the top 10 driving finance this year.
What Is a Stock Market?
A stock market is a place where people buy and sell shares, which are small pieces of companies like Apple or Reliance Industries. It’s like a digital marketplace where businesses raise money to grow, and investors try to make profits. When you buy a share, you own a tiny part of the company. If the company does well, your shares can grow in value, or you might get dividends—partcopy of profits.
Stock markets do three big things:
- Help Companies: Businesses sell shares to get cash for growth without borrowing.
- Help Investors: People can grow their money by buying shares that rise in value or pay dividends.
- Help the Economy: Markets move money from investors to businesses, creating jobs and growth.
The first stock market began in Amsterdam in 1602. Today, they’re digital and super fast, with trades happening in a split second.
How Many Stock Markets Are There?
In 2025, there are about 60 major stock exchanges around the world, based on data from groups like the World Federation of Exchanges. These range from huge markets like the New York Stock Exchange to smaller ones in different countries. Out of these, 21 exchanges have a total value of listed companies—called market capitalization—over $1 trillion. These big players make up about 87% of the world’s stock market value.

- They’re for Everyone: Apps like Zerodha or Robinhood let millions of people invest, not just the wealthy.
How to Get Started
Want to try investing? Here’s how:
- Get an Account: Use platforms like Zerodha (India) or Interactive Brokers (global).
- Learn First: Study companies and markets to make smart choices.
- Start Small: Only invest money you can afford to lose, as markets can be risky.
- Stay Updated: Check news on Reuters, Bloomberg, or The Interview Times.
Note: Stocks can grow your money by about 10% a year (based on S&P 500 history), but inflation and risks can cut into profits. Talk to a financial advisor first.
