Magdalena Martullo-Blocher has an estimated net worth of $11.7 billion, according to Forbes Real-Time Billionaires, Magdalena Martullo-Blocher profile (figures as of October 20, 2026). That is up from $4.3 billion in 2019.
Magdalena Martullo-Blocher is a Swiss businesswoman and politician tied closely to EMS-Chemie, a major Swiss polymer and chemical manufacturer. Before joining the company, she worked in management roles at Johnson & Johnson and at Swiss beverage maker Rivella. She joined the EMS-Chemie board in 2001. In 2004, she took over the company after her father, Christoph Blocher, left for the Swiss federal council.
Her wealth comes from her stake in EMS-Chemie, which Forbes places in the chemicals business within manufacturing. After her father sold his shares to Magdalena and her siblings, she became a key owner and leader of the business. She later moved into public office too. In 2015, she was elected to the Swiss parliament as a national councilor, following a path similar to her father's move from business into politics.
How Magdalena Martullo-Blocher built her fortune
Most of Magdalena Martullo-Blocher's fortune comes from her holding in EMS-Chemie, the Swiss chemical and polymer group. Forbes says she owes her wealth to that stake. Her path to the top was tied to both ownership and management. She first built corporate experience at Johnson & Johnson and Rivella, then moved into the family company's leadership. By 2001, she had joined the board, giving her a direct role in the business before taking charge.
A major turning point came in 2004. Her father left to take a seat on the Swiss federal council, and she took the reins at EMS-Chemie. Around that transition, he sold his shares to Magdalena and her siblings, who also became billionaires. That combination of family ownership and executive control shaped her wealth. Forbes classifies her as not self-made, and places her business interests in chemicals within the broader manufacturing industry.
Forbes wealth estimate over time
Forbes has tracked large swings in Martullo-Blocher's fortune over the years. It estimated her wealth at $4.3 billion in 2019, then $5 billion in 2020. The figure climbed to $7.1 billion in 2021 and $7.6 billion in 2022 before slipping to $6.7 billion in 2023 and $6.4 billion in 2024. Those changes match the value Forbes assigns to her EMS-Chemie stake, which is the main source behind the estimate.
The estimate then moved sharply higher. Forbes put her at $8.8 billion in 2025 and $10.3 billion in 2026 on its World's Billionaires List. On Forbes' real-time billionaires tracker, the figure reached $11.7 billion as of October 20, 2026. Because her fortune is centered on one major industrial holding, changes in Forbes' estimate are closely connected to how that EMS-Chemie stake is valued at a given time.
