The Hartono brothers, the owners of Djarum and Bank Central Asia, are the richest people in Indonesia in October 2026, with at least $18.7 billion from their bank stake alone. Low Tuck Kwong follows with about $11.9 billion from coal, and Prajogo Pangestu has about $9.5 billion. The 2014 list is gone; we rebuilt it from share prices on 23 October 2026.
| Rank | Name | Net worth |
|---|---|---|
| 1 | Budi and Michael Hartono | $18.7 billion |
| 2 | Low Tuck Kwong | about $11.9 billion |
| 3 | Prajogo Pangestu | about $9.5 billion |
| 4 | Anthoni Salim | at least $1.6 billion |
| 5 | Susilo Wonowidjojo | about $1.2 billion |
1. Budi and Michael Hartono: $18.7 billion
The Hartono brothers inherited the Djarum clove cigarette company in 1963 and turned a kretek business into the owner of Bank Central Asia, which they took over in 2002. A joint holding company has held about 54.94 percent of the bank since at least 2017. Djarum itself is private and is not in our number.
54.94 percent of BCA’s Rp 617 trillion market value at 18,115 rupiah to the dollar gives $18.7 billion for the pair. Split between the brothers, each has about half.
2. Low Tuck Kwong: about $11.9 billion
He worked at his father’s construction firm in Singapore as a teenager, moved to Indonesia in 1972 and bought his first Kalimantan coal concession in the 1990s. His company Bayan Resources produced 56.9 million tonnes of coal in 2024, roughly 7 percent of national output. In August 2024 he transferred part of his holding to his daughter Elaine.
Bayan’s market value is Rp 358 trillion. We assume the family still holds about 60 percent, our estimate, which gives roughly $11.9 billion.
3. Prajogo Pangestu: about $9.5 billion
Pangestu started as a timber trader and now controls Barito Pacific, which owns petrochemicals and geothermal power, and the clean-energy listing Barito Renewables. He is credited with 71 percent of Barito Pacific, 22 percent of Barito Renewables and 5 percent of Chandra Asri Petrochemical.
Barito Pacific (Rp 135 trillion), Barito Renewables (Rp 318 trillion) and Chandra Asri (Rp 115 trillion) at those stakes add up to about Rp 172 trillion. Some of those holdings may overlap, so this is an upper estimate.
4. Anthoni Salim: at least $1.6 billion
The son of the founder of the Salim Group is the head of Indofood, the instant-noodle and food group, and has holdings in plantations, retail and cars. The old article listed him at number 3.
We assume the family keeps about half of Indofood’s Rp 59 trillion market value. His private holdings sit on top of that.
5. Susilo Wonowidjojo: about $1.2 billion
Gudang Garam, the clove cigarette maker his family owns, was founded in 1958 and holds about a third of the national market. The share price has slid, which is why the family fortune is a fraction of its former size.
We assume the family holds about two thirds of the Rp 32.6 trillion market value, our estimate.
Special mentions
Several of the fortunes from the old list sit in private groups, so there is no share price to multiply: Sukanto Tanoto (Royal Golden Eagle, $2.3 billion in the old 2014 figure), Chairul Tanjung (CT Corp), Mochtar Riady (Lippo Group) and Sri Prakash Lohia (Indorama). Eka Tjipta Widjaja, the founder of Sinar Mas, has died.

How we estimate net worth
Our estimates are based on public reporting, company valuations, and deal and earnings figures all compiled in an internal valuation model. They are approximate, and figures change over time as new information emerges.
