Gautam Adani has officially surpassed Mukesh Ambani to become Asia's richest individual, according to the latest Bloomberg Billionaires Index. Adani's net worth is now $92.6 billion, placing him 19th globally, while Ambani's wealth stands at $90.8 billion, ranking 20th. This change is driven by Adani's stock performance, which added $8.1 billion to his fortune this year. In contrast, Ambani has seen a decline of $16.9 billion in the same period due to mixed results from Reliance Industries. Despite a decline in the Sensex by 123 points on Thursday, Adani Group stocks surged, adding approximately $3.56 billion to Adani's wealth in a single day. The fluctuations in wealth among the world's billionaires highlight the competitive nature of the rankings, with several top billionaires, including Ambani, experiencing significant losses this year.
