As per the Bloomberg Billionaires Index, Reliance Industries Chairman Mukesh Ambani added a substantial $16.50 billion to his net worth in 2025. The surge coincided with a powerful rally in Reliance Industries—India’s largest company by market capitalisation—which posted its strongest performance since 2020 with shares climbing nearly 30%. Higher refining margins, telecom tariff hikes, resilient retail performance and upcoming value-unlocking catalysts collectively drove the sharp rise in Ambani’s wealth.
Following close behind is Lakshmi Mittal, Chairman of global steel major ArcelorMittal, the world’s second-largest steelmaker. Data shows that Mittal, currently the 70th richest person globally, saw his net worth rise by nearly $12 billion in 2025, taking his total wealth to $31 billion.
Sunil Mittal, founder of Bharti Enterprises, which owns telecom operator Airtel, also saw a significant jump in wealth. His net worth increased by $6 billion to $29 billion in 2025. Airtel’s stock gained 31% year-to-date, while the company reported an 89% year-on-year jump in consolidated Q2 net profit to Rs 6,792 crore.
Gautam Adani, founder of the Adani Group, added $5.9 billion to his fortune in 2025, taking his net worth to $84 billion. One of the key drivers of the rebound was the market regulator Sebi’s clean chit to Adani in the Hindenburg case, which helped restore investor confidence. Adani remains the second-richest Indian, behind Mukesh Ambani.
Meanwhile, Kumar Mangalam Birla, Chairman of the Aditya Birla Group, with a net worth of $22 billion, saw his wealth grow by $4 billion during the year. Uday Kotak, founder of Kotak Mahindra Bank, added over $2 billion to his fortune, taking his net worth to $16 billion and placing him in the top 10 richest Indians on the list.
Others featured on the list include Vikram Lal, founder of two-wheeler major Eicher Motors, and Nusli Wadia of the Wadia Group, which also owns FMCG heavyweight Britannia Industries. They are followed by Rahul Bhatia, co-founder of IndiGo, India’s largest airline by market share. Samir Mehta, chairman of the Torrent Group, also makes the cut with a net worth of $7 billion.Among the laggards, Shiv Nadar, founder of IT major HCL Tech, tops the list. With a net worth of $39 billion, his wealth declined by nearly $4 billion, according to the Bloomberg Billionaires Index. The drop comes amid heavy FII selling in IT stocks, with HCL Tech shares down 15% in 2025.
Azim Premji, Indian technology veteran and former chairman of Wipro, also saw his net worth fall by $3 billion to $28 billion. Wipro’s stock has slipped 12% since the start of the year. In 2019, Premji handed over the role of executive chairman to his son Rishad Premji, while he continues as founder chairman.
K P Singh, founder of real estate major DLF, has a net worth of $14 billion, marking a decline of $3.38 billion in 2025. Shares of DLF have fallen 17% this year, weighing on his wealth.
Rounding out the list are Dilip Shanghvi, managing director of Sun Pharmaceuticals, whose net worth has dropped by over $4 billion to $25.5 billion, and Ravi Jaipuria, chairperson of Varun Beverages, whose wealth has declined to $13 billion, Bloomberg data showed.
