is our regulated market suited to companies that can adhere to the highest standards.

This Solution Helps

  • Private Companies
  • Public Companies
  • Market Regulators


Today, more than 650 companies are traded across our Main Markets in Stockholm, Copenhagen, Helsinki and Iceland, including some of the most innovative companies in Europe. 

By listing on the Main Market, companies benefit from increased visibility and investor exposure, and Nasdaq’s efficient and independent surveillance of issuers, members and trading. More than 170 trading member firms engage in the daily trading, with most trades made by international banks and brokerage houses.


A company that considers applying for admittance to trading on Nasdaq agrees with the exchange to commence a listing process. Companies enter into a written agreement with the exchange regarding the trading of their shares, adherence to all rules and guidelines of the exchange, as amended from time to time, and commitments made to the exchange. The process and the documentation are kept confidential. On the first day of trading, Nasdaq hosts a welcome ceremony for the company, together with the advisors, at which key management and stakeholders monitor the opening and early trading in the stock.

Read detailed information about the listing process and the listing requirements in our Listing Guide and in the Rules & Regulations.


According to Nasdaq Nordic's rulebooks all members of the board and individuals in the management need to have a general understanding of stock market rules in order for the company to be eligble for a listing. Such understanding may be acquired by attending our Rules & Regulations Training. You can find this training and other training possibilities on our Nasdaq European Academy Page.

Main Market Segments

The Nasdaq Main Market is divided into three segments depending on the size of the companies.

Large Cap – companies with a share value over EUR 1 billion
Mid Cap – companies with a share value exceeding EUR 150 million but not more than EUR 1 billion
Small Cap – companies with a share value up to EUR 150 million


To keep the lists accurate, we review each segment at year-end and re-set the segments based on average market capitalization in November the year before. The change in the segments is updated on the first trading day in January each year.

Companies with a market cap value of more than 50 percent of the minimum or maximum threshold of a segment will be transferred into a new segment with immediate effect. Companies with a market cap value of less than 50 percent of the minimum or maximum segment threshold will have a transitional period until the next forthcoming review (or at least 12 months), and thus be subject to one more review before transferring into a new segment.

Through these measures, Nasdaq offers market cap classification structure in line with international standards while facilitating a model built to withstand strong market fluctuations and thus support financial stability for our listed companies

Main Market Indexes

Nasdaq is dedicated to designing powerful, relevant index and benchmark families that are in sync with the continually changing market environment.

As a leading global index provider, with over 40,000 indexes across geographies and asset classes such as equities, fixed income and commodities, our indexes are tracked by institutional and individual investors and media worldwide.

Our sector indexes are based on industry classification. Nasdaq uses ICB (Industry Classification Benchmark) which is maintained and operated by the FTSE Group. Industry Classification Benchmark (ICB) is a globally recognized standard for categorizing companies and securities across four levels of classification. Each company is allocated to the sub-sector that most closely represents the nature of its business, which is determined by its primary source of revenue and other publicly available information.

Why list on Nasdaq Main Market?

Quality Stamp

A listing on the Main Market generally serves as evidence of a company adhering to the highest standards and as such provides a quality stamp. Many companies which list on the Main Market experience greater public exposure, credibility and interest in the company and its business.


When listing with Nasdaq, you are automatically included in our segments, industries and indexes. This positions your brand in peer comparisons and surveys alongside companies that match your size and profile.

Broader and International Investor Base

One of the main drivers behind a listing on the Main Market is to make the company’s shares more eligible to institutional investors, such as investment funds. Interest by international investors is generally greater for companies listed on the Main Market.

I really think the Nasdaq brand adds both visibility and credibility. It’s a well-known brand globally and can open many doors.
