The year 2025 turned out to be a period of significant shifts in personal wealth among India’s richest individuals, with fortunes rising sharply for some and declining noticeably for others. While precious metals performed strongly, the bigger story unfolded in the equity markets, where stock movements played a decisive role in shaping billionaire wealth. India’s wealth landscape reflected both the resilience and volatility of its economy, with gains driven by strong corporate performance in some sectors and losses triggered by market weakness in others.
According to data from the Bloomberg Billionaires Index, Mukesh Ambani emerged as the biggest wealth gainer among Indian billionaires in 2025. The chairman of Reliance Industries added approximately $16.5 billion to his net worth over the year, making him the most significant beneficiary of market movements. This surge was largely powered by a near 30 percent rise in Reliance Industries’ share price, its strongest performance in several years. The rally was supported by stable refining margins, higher telecom tariffs, and consistent growth in the retail business. Investors also responded positively to expectations of future value unlocking across Reliance’s diverse portfolio, which further strengthened confidence in the company’s long-term prospects.
Close behind Ambani was steel magnate Lakshmi Mittal, whose wealth rose by nearly $12 billion during the year, taking his net worth to around $31 billion. The improvement in global steel demand and a recovery in metal prices played a key role in boosting the valuation of ArcelorMittal, the company he leads. As a result, Mittal climbed higher among the world’s wealthiest individuals, benefiting from renewed investor interest in the global metals sector.
Sunil Mittal, founder of Bharti Enterprises, also recorded a strong year in terms of wealth creation. His net worth increased by about $6 billion to reach nearly $29 billion. This growth was driven by the impressive performance of Bharti Airtel, whose shares gained roughly 31 percent during the year. The telecom operator posted strong earnings growth, supported by rising subscriber numbers, improved pricing, and better operating margins. These factors combined to push the company’s valuation higher and strengthen investor confidence.
Gautam Adani also added substantially to his wealth in 2025, with an increase of nearly $5.9 billion, taking his net worth to around $84 billion. The recovery came after improved market sentiment toward the Adani Group, particularly following regulatory clarity and a clean chit from market authorities. This helped restore investor confidence after a turbulent period, allowing Adani to retain his position as India’s second-richest individual.
Kumar Mangalam Birla saw steady gains as well, with his wealth increasing by nearly $4 billion to reach about $22 billion. The performance of Aditya Birla Group companies, backed by consistent demand and stable operations, contributed to this rise. Similarly, Uday Kotak added more than $2 billion to his fortune during the year, supported by the steady performance of Kotak Mahindra Bank and continued trust in the bank’s balance sheet and governance standards.
Several other prominent business leaders also featured among the year’s top wealth gainers. Vikram Lal benefited from strong performance at Eicher Motors, while Nusli Wadia saw gains tied to the performance of his group companies in FMCG and aviation. Rahul Bhatia of IndiGo gained from sustained demand in the aviation sector, as air travel continued to recover strongly. Samir Mehta of the Torrent Group also joined the list, with his net worth reaching around $7 billion amid stable growth across the group’s businesses.
However, 2025 was not a positive year for everyone. Some of India’s most well-known billionaires saw their wealth shrink due to weaker stock performance in key sectors. Shiv Nadar, founder of HCL Technologies, experienced one of the biggest declines, with his net worth falling by nearly $4 billion to about $39 billion. The drop was largely due to selling pressure in IT stocks, as global technology spending slowed and investor sentiment weakened.
Azim Premji also saw his wealth decline by roughly $3 billion, bringing his net worth down to around $28 billion. Shares of Wipro, the IT major he founded, fell during the year amid concerns over growth and profitability. Although Premji stepped down from executive responsibilities several years ago, his wealth remains closely tied to the company’s market performance.
Real estate tycoon K P Singh faced a decline of about $3.38 billion in his net worth, which fell to approximately $14 billion. Shares of DLF dropped significantly during the year, reflecting challenges in the real estate sector and softer investor sentiment. Similarly, Dilip Shanghvi of Sun Pharmaceuticals saw his fortune shrink by more than $4 billion as pharmaceutical stocks struggled to gain traction in the market.
Rounding off the list of major losers was Ravi Jaipuria, whose wealth declined to about $13 billion. The fall was linked to pressure on shares of Varun Beverages, which faced market headwinds during the year despite strong brand presence.
Overall, 2025 highlighted how closely billionaire wealth in India is tied to stock market performance and sectoral trends. While strong corporate earnings and investor confidence helped some business leaders significantly expand their fortunes, others were impacted by global uncertainty, sector-specific challenges and shifting market sentiment. The year served as a reminder that wealth creation at the very top can be swift, but so can reversals, depending on how markets evolve.
