Conglomerate Dominance in Indonesia's Stock Market 2025

Market Capitalization Leadership

The Indonesian stock market in 2025 is witnessing a significant trend where conglomerate-affiliated companies are dominating the market capitalization landscape. At the forefront is PT Barito Renewables Energy Tbk (BREN), maintaining its position as the largest company by market capitalization with an impressive value of Rp 1.294,28 trillion. This places BREN ahead of banking giant PT Bank Central Asia Tbk (BBCA), which follows with a market capitalization of Rp 992,36 trillion.

Wealth Surge of Key Conglomerates

The dominance of conglomerates is further emphasized by the rising wealth of key figures. Prajogo Pangestu, the owner of Barito Group, has seen his wealth skyrocket to US$ 46.1 billion as per the Bloomberg Billionaires Index. This significant increase in wealth reflects the strong performance of his companies in the market, particularly BREN, which has been a major contributor to his overall wealth.

Market Trends and Implications

The trend of conglomerate dominance in the Indonesian stock market highlights the substantial influence of large national conglomerates on the country's capital market. This concentration of market capitalization among a few large players, particularly those affiliated with well-known conglomerates, underscores the market's structure and investor preferences. The performance of these conglomerate-affiliated companies is likely to continue shaping the overall market dynamics in the near future.
