Indonesia is home to some of Southeast Asia’s most powerful entrepreneurs and business families. From coal mining and energy to banking, petrochemicals, food, healthcare and data centers, the country’s wealthiest people have built major business empires across a wide range of industries.
The ranking of Indonesia’s richest people can change frequently because many billionaires hold significant stakes in publicly traded companies. As of August 2026, Forbes Real-Time Billionaires data placed Low Tuck Kwong at the top, followed closely by Prajogo Pangestu and R. Budi Hartono. Recent estimates put the combined wealth of the top 10 at around $100 billion.
Who Is the Richest Person in Indonesia in 2026?
Low Tuck Kwong is currently ranked as Indonesia’s richest person.
The founder of coal producer Bayan Resources, Low Tuck Kwong has built his fortune primarily through the energy and mining sector. Forbes Real-Time data reported his wealth at approximately $16.8 billion in early August 2026, although the figure changes with market movements.
His rise to the top is particularly notable because Prajogo Pangestu, who had previously held the No. 1 position, has remained extremely close behind him.

Why Are Indonesia’s Billionaires So Wealthy?
Indonesia has a large natural-resource base and a huge domestic consumer market. These factors have created opportunities for entrepreneurs in several industries.
Natural Resources
Coal, nickel, palm oil and other natural resources remain major sources of wealth. Low Tuck Kwong and Lim Hariyanto Wijaya Sarwono are examples of billionaires whose fortunes are connected to these industries.
Banking and Finance
Indonesia's expanding financial sector has created enormous opportunities for business families. The Hartono family's connection to BCA is one of the country's most prominent examples.
Petrochemicals and Energy
Prajogo Pangestu and Sri Prakash Lohia demonstrate how petrochemicals and manufacturing can create global-scale fortunes.
Digital Infrastructure
Indonesia's rapidly growing digital economy has created a new generation of technology billionaires. Otto Toto Sugiri and Marina Budiman are particularly notable examples.
Indonesia’s Billionaire Economy Is Changing
For many years, Indonesia's richest people were primarily associated with tobacco, banking, mining, plantations and traditional conglomerates.
That picture is now becoming more diverse.
Data centers and digital infrastructure have moved into the top tier of Indonesian wealth creation. Otto Toto Sugiri and Marina Budiman both rank among the country's 10 richest people, demonstrating the financial potential of Indonesia's digital transformation.
At the same time, traditional sectors such as coal, petrochemicals, banking and consumer products continue to dominate the wealth rankings.
Indonesia’s Richest People and the Future
The future of Indonesia's billionaire economy could increasingly depend on energy transition, artificial intelligence, digital infrastructure, mining, manufacturing and consumer spending.
Indonesia is also strategically important for minerals such as nickel, which are essential to several modern industries, including battery manufacturing.
Meanwhile, the rapid growth of cloud computing and artificial intelligence is likely to increase demand for data centers and energy infrastructure.
These trends could create new billionaire fortunes while reshaping the existing rankings.
Final Thoughts
Indonesia's richest people come from remarkably different backgrounds. Low Tuck Kwong built his fortune in coal, Prajogo Pangestu expanded from timber into energy and petrochemicals, R. Budi Hartono built enormous wealth through banking and consumer businesses, while Otto Toto Sugiri and Marina Budiman represent the country's rapidly growing digital infrastructure sector.
The ranking also demonstrates how quickly billionaire fortunes can change. Forbes Real-Time estimates fluctuate with stock prices and other market conditions, meaning today's No. 1 may not remain there permanently.
As Indonesia continues to develop into one of Southeast Asia's largest economies, its richest entrepreneurs are likely to remain major players in energy, finance, technology, manufacturing and natural resources.
