Vanisha Mittal Bhatia – $18 Billion

Vanisha’s father is Lakshmi Mittal, the CEO, and chairman of ArcelorMittal, the world’s largest steelmaking company. Like many on this list, she had the inside track to a great position in the family business.

She is the chief strategy officer and non-independent director of the company. Her dad is worth a huge amount and Vanisha stands to inherit a portion of that fortune and get a large equity stake in the company when he passes.
