Martua Sitorus Net Worth

Martua Sitorus has an estimated net worth of $3.5 billion, according to Forbes Real-Time Billionaires, Martua Sitorus profile (figures as of October 20, 2026). That is up from $1.7 billion in 2019.

Martua Sitorus is an Indonesian businessman known for building major palm oil businesses. He cofounded Wilmar with Kuok Khoon Hong in 1991, and the company grew into one of the world’s largest palm oil traders. Before that, he was an economics student who traded shrimp as a teenager and later moved into palm oil. Forbes put his net worth at $3.5 billion on its real-time billionaires tracker as of October 20, 2026.

His wealth comes mainly from palm oil and other manufacturing and property businesses. After Wilmar, he and his brother Ganda cofounded KPN, formerly called Gama, with interests in palm oil plantations, property development and cement manufacturing. The family’s cement company Cemindo Gemilang listed shares in 2021 and raised $77 million. Their hospital company Murni Sadar followed with a 2022 IPO that raised $21 million.

How Martua Sitorus built his fortune

Sitorus made his name in palm oil. In 1991, he and Kuok Khoon Hong started Wilmar, a Singapore-based company that became one of the world’s biggest palm oil producers and traders. Wilmar’s operations grew across oil palm cultivation, edible oils, sugar, specialty fats, oleochemicals, biodiesel, fertilizers and grains processing. The company also built a wide manufacturing and distribution footprint, with more than 300 plants and reach across China, India, Indonesia, the United States and about 50 other countries.

He later expanded beyond Wilmar. Sitorus stepped off Wilmar’s board in 2018, but he and his brother Ganda built KPN, once known as Gama, into a broader business group. Its interests include palm oil plantations, property development and cement manufacturing. In 2024, KPN’s property arm Gama Land worked with the Ciputra Group to build a township in Medan, North Sumatra. The family also took Cemindo Gemilang public in 2021 and brought Murni Sadar to market in 2022.

What Forbes says about his net worth

Forbes has tracked Sitorus’s fortune rising over time. It estimated his net worth at $1.7 billion in 2019, then $2.9 billion in 2022, and $3.6 billion on the 2026 World’s Billionaires List. That increase lines up with his long exposure to palm oil and his family’s added stakes in cement, hospitals and property. He is also listed by Forbes as self-made, with wealth tied to palm oil and the manufacturing industry.

The latest move was small rather than dramatic. Forbes showed $3.5 billion on its real-time billionaires tracker in October 2026, a bit below the annual 2026 list figure. Recent business activity helps explain why his wealth base is broader than one company. Cemindo Gemilang raised $77 million in its 2021 share sale, Murni Sadar raised $21 million in 2022, and Gama Land pushed ahead with a Medan township project in 2024.
