Investors often focus on the primary and secondary markets, but there’s a lesser-known space called the pre-primary market – where unlisted companies operate. These are businesses that haven’t gone public yet but play a crucial role in the broader stock market ecosystem. Many companies eventually choose to go public to raise funds for growth or boost their visibility, although some remain privately held by choice. Some of these private firms grow into significant players, not just in India but globally. Depending on their size and stage of growth, unlisted companies can present exciting opportunities for investors. Let’s take a closer look at some of the biggest unlisted companies in India.

#1 National Stock Exchange of India (NSE) – Most Valuable Unlisted Company in India

In recent times, the volumes of derivatives and stock trading have witnessed significant expansion, especially in the wake of the Covid-19 pandemic. This surge in trading activities has resulted in a substantial increase in revenues. The National Stock Exchange (NSE) business model is designed to offer revenue predictability and impressive return ratios. These factors contribute to NSE’s status as one of the biggest unlisted companies in India. In contrast, the Bombay Stock Exchange (BSE) is already a publicly listed entity. It is plausible that, given these dynamics, the NSE might also make its way out of the unlisted companies category in the coming years.
