Martua Sitorus's net worth stands at $3.6 billion, per Forbes' Real-Time Net Worth tracker, ranking him #1189 globally. That figure is unremarkable on its own. What is unusual is how little it has moved: Sitorus co-founded Wilmar International, one of the world's largest listed palm oil traders, but he left its board in 2018 and its daily operations in 2013, so Wilmar's own stock swings no longer touch his tracked fortune at all. His money now sits almost entirely in companies most investors have never heard of.
Forbes' Real-Time Net Worth tracker (forbes.com/profile/martua-sitorus) prices Sitorus at $3.6 billion, global rank #1189 on "Forbes' 2026 Billionaires" list. That exact figure and rank recur, independently, across a long list of sites that cite the same Forbes page at different points in 2025 and 2026, an unusual pattern this series has not seen elsewhere: most trackers move week to week, but this one has held inside a narrow $3.45 billion to $3.6 billion band for close to a year.

| Multiple aggregator profiles (Celebrity Net Worth, TheRichest, Tatler Asia) | Various 2025 to 2026 snapshots | $3.6 billion, global rank #1189 |

No dated Bloomberg Billionaires Index figure naming Sitorus individually turned up in this research. Bloomberg's own Indonesia rankings, as cited elsewhere by Bloomberg Technoz through 2026, name Sukanto Tanoto, Prajogo Pangestu, Low Tuck Kwong and Robert Budi Hartono among the Indonesians it prices, but not Sitorus. We are stating that plainly rather than guessing at a figure Bloomberg has not published.
Sitorus resigned as a Wilmar International board director effective 15 July 2018, one week after Greenpeace publicly linked him to deforestation at an affiliated plantation, and he had already stepped back from Wilmar's operations as chief operating officer in 2013. No current, dated disclosure of him holding Wilmar shares directly turned up in this research, so this article does not claim either that he does or does not; the honest answer is unconfirmed.
His confirmed public holding runs through KPN Corporation (formerly Gama Group), which he co-founded with his brother Ganda Sitorus:
| Company | Ticker | Listed | What Forbes reported it raised |
|---|---|---|---|
| PT Cemindo Gemilang Tbk ("Semen Merah Putih" cement) | CMNT (IDX) | 8 September 2021 | About $77 million |
| PT Murni Sadar Tbk (Murni Teguh Hospitals) | MTMH (IDX) | 2022 | About $21 million |
A prospectus-era disclosure from CMNT's 2022 filings put roughly 87.37% of the cement maker under WH Investments Pte Ltd, a Singapore holding vehicle in which Sitorus holds the controlling interest, wholly owning two of its component entities and 67% of a third. That chain is several years old and may have shifted since; no more current disclosure of it surfaced in this research. Neither CMNT nor MTMH appears in NetWort's curated ticker universe, so neither carries an internal asset link here. Wilmar itself, listed on the Singapore Exchange, is also outside that universe.
A corruption case tied to Wilmar Group's crude palm oil export permits, part of a wider 2022 Indonesian graft scandal over CPO export licensing, pulled Sitorus's name into headlines by association in mid-2025. KPN Corporation issued a public clarification, reported 8 July 2025 by several Indonesian outlets, stating plainly that Sitorus had left Wilmar's operations in 2013 and its board in 2018, and had no involvement in the case.
The underlying case proceeded without him. On 3 March 2026, the Jakarta Corruption Court found Wilmar's then legal head, Muhammad Syafei, guilty of coordinating a $4 million bribe, together with two lawyers, to judges at that same court to secure earlier acquittals for Wilmar Group, Musim Mas Group and Permata Hijau Group in the original export-permit case. Syafei received a six-year sentence; the two lawyers received 14 and 16 years.
No death and no personal litigation was found for Sitorus himself in this research. He was born 18 February 1960 in Pematang Siantar, North Sumatra, and is 66 as of this article.
Most fortunes this series covers move because a single listed stock moves. Sitorus's does not have that lever: Wilmar's share price no longer touches his tracked wealth, and CMNT and MTMH are comparatively thin, IDX-listed vehicles rather than the kind of large-cap that dominates a Real-Time tracker's daily estimate. That likely explains the unusually flat, narrow band Forbes has shown for close to a year.
It cuts both ways. A number that does not move could mean a genuinely stable fortune, or it could mean the underlying private structure, last disclosed in detail around the 2022 CMNT prospectus, simply is not being re-priced very often. Without a fresher ownership disclosure, there is no way to tell which is closer to true from the outside.
A billionaire's fortune and the public company bearing his name are not the same thing the moment he actually leaves it, and Sitorus left Wilmar's board seven years ago. Owning a stake in a listed company someone founded is not the same as owning a stake in everything that person now owns.
