Abstract
This article examines the role of companies and their investment activity in the development of investment processes in the economy of Kazakhstan. The study analyzes the dynamics of investments in fixed assets, as well as the structure of investors in the secondary stock market. The study is based on statistical data for the period 2019-2025, including an analysis of market turnover and the participation of individuals and legal entities in investment activities. The results of the study show a steady increase in investments in fixed assets, as well as an increase in the participation of companies in the stock market. The data obtained indicate that legal entities are strengthening their role in investment processes, while individuals remain active market participants. The growth in stock market turnover and changes in investor structure reflect the development of Kazakhstan's investment environment and financial infrastructure. In general, the results of the study confirm that an increase in the investment activity of companies contributes to the development of the national capital market and the economic growth of the country.
