Arini Subianto's net worth was $2.4 billion per Forbes' Indonesia's 50 Richest 2025 list, updated on 10 December 2025, where she ranked 33rd. Forbes' 2024 list had put her at $2 billion, so on this one tracker her figure rose about 20% in a year. Forbes also describes her as Indonesia's richest woman and lists the entry as "Arini Subianto & family".
Subianto, 55, is president director of Persada Capital Investama, the family holding company she took over after her father, Benny Subianto, died in 2017. Forbes traces the fortune to coal and palm oil interests.
| Publisher | List | Figure | Rank in Indonesia |
|---|---|---|---|
| Forbes, Indonesia's 50 Richest 2022 | 2022 | $1.5 billion | 28th |
| Forbes, Indonesia's 50 Richest 2024 | 2024 | $2 billion | not confirmed |
| Forbes, Indonesia's 50 Richest 2025 | 10 December 2025 | $2.4 billion | 33rd |
All three rows are Forbes annual list snapshots, so the comparison stays inside one series. The 2022 and 2024 figures reach us through coverage by Katadata and CNBC Indonesia, and we have not confirmed the exact publication dates of those lists, so treat them as list-year figures.
We did not find a Bloomberg Billionaires Index figure for Subianto, and we did not find a dated Forbes real-time figure for her in 2026. Without a second tracker there is no disagreement to show here. That is itself informative: a fortune that sits in a private holding company is often covered by one publisher only.
The anchor is Persada Capital Investama, a private company whose businesses, per Indonesian coverage of Forbes' profile, span plantations, agriculture, construction, property and mining. Reports describe Persada as a minority shareholder in coal miner Alamtri Resources Indonesia, formerly Adaro Energy, renamed in November 2024.
Subianto also holds shares personally. Stockwatch.id, reporting April 2026 shareholder data, listed 80.10 million Alamtri shares, or 0.273%, in her name. That is a different claim from Persada's stake and should not be added to it. BCA Sekuritas also reported that she bought shares of palm oil company Triputra Agro Persada (TAPG) in February and March 2026 at prices between Rp1,510 and Rp1,565 per share.
Forbes has also said she has invested in technology startups through Persada since 2017. Private stakes like these cannot be priced from a share ticker, which is where a tracker's own judgment enters the number.
Alamtri, the company where Persada holds a minority stake, is the same business behind Boy Thohir's profile. Two Forbes entries therefore sit on the same listed company, but their holdings are separate and must not be combined. The listed stock trades on the IDX as ADRO.
None of the publishers we found says which holding, or which market move, lifted Forbes' figure from $2 billion to $2.4 billion. The list total did rise sharply that year, from $263 billion to $306 billion, per Forbes, but that explains the climate rather than her specific number.
Not very. The listed Alamtri shares can be checked against filings, but the main holding, Persada, is private, and Forbes does not publish how it values it. The "& family" label also means the figure prices a household, not a single balance sheet. Compare Ciliandra Fangiono, whose figure is also a Forbes family entry but sits mostly in one listed company, or Haryanto Tjiptodihardjo, where several trackers have disagreed.
A private holding means one voice. With a single tracker covering her, the figure is only as good as that tracker's valuation of unlisted assets.
Personal and holding-company stakes are different claims. Her 0.273% personal Alamtri position and Persada's larger interest are not the same number. Nothing in the public record found for this article suggests anything beyond openly disclosed shareholdings.
