Mukesh Ambani’s net worth stands at $96.3 billion as of December 17, while Gautam Adani’s is $80.8 billion. Ambani, India’s richest man and Reliance Industries Chairman, faced wealth erosion this year due to underperformance in the energy and retail businesses, slowing sales growth, and investor concerns over debt, despite the company’s focus on digital, renewables, and retail expansion.
