In 2025, India's wealthiest individuals experienced significant wealth fluctuations, with some billionaires adding billions to their fortunes while others saw declines. Mukesh Ambani led the gains, adding $16.5 billion as Reliance Industries' shares surged nearly 30%. Lakshmi Mittal followed, increasing his net worth by nearly $12 billion, and Sunil Mittal added $6 billion. These gains were attributed to strong stock market performance, improved business operations, and positive investor sentiment in specific sectors, contrasting with wealth erosion in IT, real estate, and pharmaceuticals.
