India's wealthiest families experienced a bifurcated year in 2025, with some billionaires achieving significant wealth gains while others faced declines due to volatile equity markets and foreign investor pullbacks. Lakshmi Mittal, chairman of ArcelorMittal, led the gainers with a 59% increase in wealth, attributed to strong earnings and favorable trade policies. Eicher Motors founder Vikram Lal and Bharti Airtel chairman Sunil Mittal also saw substantial wealth growth, driven by strong company performance and market share gains.
