Gautam Adani's wealth gains this year were wiped out after he was charged by US prosecutors with helping drive a $250 million bribery scheme, sending his companies' stocks and bonds tumbling.

The net worth of Asia's second-richest person sank more than $15 billion earlier on Thursday, according to the Bloomberg Billionaires Index. His fortune stood at around $73 billion at 12 p.m. in Mumbai, below the $84.3 billion at the end of 2023, and down from a June 3 peak this year of $122 billion.
