Biography
Lakshmi Mittal serves as chairman of $61.3 billion (revenue) ArcelorMittal, the world's largest steel and mining company by output.
Hailing from a steel clan, he separated from his siblings to start Mittal Steel then went on to merge the company with France's Arcelor in 2006.
ArcelorMittal reported net income of $3.15 billion in 2025, a 142% rise from $1.3 billion in 2024.
In 2021, Mittal ceded the CEO's position to his son, Aditya Mittal, but retained the title of executive chairman of ArcelorMittal.
A long-time resident of the U.K., Mittal shifted his base to Switzerland following an exodus of the wealthy hit by the U.K.'s new tax regime.
Perspective on their fortune
Gold
Everyday luxury

A Lakshmi Mittal's fortune is equivalent to 200 of gold, but this may be difficult to value, as we don't usually have a handful of gold bars in our piggy bank.

A standard gold ring typically weighs between 4 and 7 grams. Let's say this one weighs 5 grams. It's usually 18k gold.
Based on today's gold price (not taking into account the jeweler's fee, shipping, or anything else), that gold ring would be worth $556.3
Lakshmi Mittal could buy 53,211,060 gold rings. That's a lot of fingers and a lot of gifts!!
And if the number of rings is difficult to visualize, all these rings would need 10 trucks to transport them, But we can be almost certain that Lakshmi Mittal will have enough left over to pay for the gas for those trucks.
