Prajogo Pangestu's net worth was reported at roughly $14.3 billion by mid 2026, down from about $39.5 billion at the end of 2025. That is a fall of roughly $29.6 billion, or 64.2%, in six months.
He did not sell a business. The Indonesian stock market repriced his holdings, and because almost all of his wealth sits in listed shares of companies he controls, the estimate followed.
He built his fortune starting in timber in the 1970s, then moved into oil, gas and petrochemicals. Today the wealth is concentrated in the listed companies of the Barito group, including Chandra Asri, Indonesia's largest petrochemical producer.
That concentration is the whole story. When the group's shares fall together, there is nothing else in the portfolio to cushion it.
His listed holdings did not drift down. They collapsed together through 2026.
| Stock | Year to date move, 2026 |
|---|---|
| TPIA | About minus 79% |
| CUAN | About minus 73% |
| BREN | About minus 65% |
| PTRO | About minus 58% |
| CDIA | About minus 47% |
| BRPT | About minus 41% |
The declines deepened after MSCI delayed a rebalancing of Indonesian stocks, citing concerns about trading manipulation and the high concentration of share ownership within certain groups. On one particularly bad session, Jakarta Globe reported he lost $2.7 billion in a single day as Indonesian tycoons faced a market rout.
The fall cost him two titles. He lost the position of Southeast Asia's richest person to Vietnam's Pham Nhat Vuong, and Bloomberg's index showed Sukanto Tanoto overtaking him as Indonesia's richest.
Better than most people in this position, and still not precise.
His main holdings are listed on the Indonesia Stock Exchange, so they carry live prices and disclosed ownership percentages. That is the good case. But a controlling stake cannot be sold at the screen price, since offloading a position that large would move the market against the seller long before it cleared. Whether a publisher applies a discount for that, and how big a discount, changes the answer by billions.
This is also why the rankings disagreed about who Indonesia's richest person actually was during 2026, with Forbes, Bloomberg and Indonesian outlets each reaching different conclusions in different months.
The lesson here is not about Indonesian petrochemicals. It is that a portfolio built on companies in one group, in one sector, on one exchange has no internal shock absorber.
Elon Musk lost roughly $600 billion in six weeks through the identical mechanism, on a different continent, in different industries. The scale differs. The structure does not.
Indonesian investors are unusually exposed to this, because a portfolio of IDX blue chips can end up correlated to the same commodity cycle and the same foreign-flow decisions without looking concentrated on paper.
