Nasdaq Stock Market Core Facts
The Nasdaq Stock Market is one of the largest electronic stock exchanges in the world, operating as a platform for buying and selling shares of publicly listed companies. It was founded in 1971 and is known for its electronic trading model, which relies on a network of computers rather than a centralized trading floor. The exchange is headquartered in New York City and is owned by Nasdaq, Inc., a publicly traded holding company. Many technology and growth-oriented companies choose to list on Nasdaq because of its reputation as a hub for innovation-driven businesses. The exchange also lists companies in sectors such as consumer services, biotechnology, and finance. For more details on its operations, see the official Nasdaq, Inc. overview at https://www.nasdaq.com.
Nasdaq operates several distinct markets, including the Nasdaq Global Select Market, Nasdaq Global Select Market, Nasdaq Global Select Market, and Nasdaq Capital Market. These tiers are based on company size, liquidity, and regulatory requirements. Companies listed on the Global Select Market must meet the highest financial and governance standards. The Capital Market tier is designed for smaller, early-stage companies that do not yet meet the stricter listing requirements. Each market segment provides a different level of visibility and regulatory oversight. The exchange facilitates trading in thousands of securities daily through its advanced electronic matching engine.

Nasdaq Market Structure and Trading Facts
Electronic Trading and Liquidity
Nasdaq pioneered electronic trading in the United States, replacing the traditional open outcry system with a fully automated matching engine. This structure allows for faster order execution and lower transaction costs compared to floor-based exchanges. The market uses a designated market maker model, where specific firms are responsible for maintaining liquidity in assigned stocks. These market makers quote both bid and ask prices, helping to ensure continuous trading even during periods of low volume. The exchange also employs a sophisticated surveillance system to detect and prevent market manipulation and insider trading. Regulatory oversight is provided by the U.S. Securities and Exchange Commission, which enforces federal securities laws. More information on market regulation is available
