Oprah is one of the most famous women in the world, rising from poverty to now having a net worth of $2.9 billion. Not only is she one of the richest people in the world, she's also regarded as the richest black woman. Now she'll have to move over, as Folorunsho Alakija is now the richest black woman in the world.
This 62 year old is an oil tycoon and owner of Framfa Oil, which has a 60% stake in Nigeria's OML 127 oil block. This has shot her net worth to $7.3 billion dollars. She has a story much like Oprah, as she started off as a bank secretary and worked hard before she was able to open up her own business. Although Oprah may no longer be the richest black woman in the world, she's still one of the wealthiest overall. Her net worth will continue to grow with the many companies she owns, including her own television network.
