8th richest in the world? On 5 March 2021, Forbes listed Roman Arkadyevich Abramovic net worth at US$14.5 billion, ranking him 113 on the Billionaires 2020 Forbes list.
I assume the article is based on the time of construction of this yacht he used to be top 10(net worth of $20 million). Bill Gates was the richest person back then with net worth of $50 million.
