Bloomberg Billionaires Index 2025: Mukesh Ambani Retains Top Spot; Lakshmi Mittal Emerges as the Biggest Percentage Gainer

The year 2025 has been a year of massive wealth accumulation for India’s corporate titans. According to the latest Bloomberg Billionaires Index data, Reliance Industries Chairman Mukesh Ambani continues to lead the pack as India's wealthiest individual. However, the spotlight this year has also shifted to steel tycoon Lakshmi Mittal, who recorded the highest percentage growth in his net worth among top Indian billionaires.

Mukesh Ambani: The Only Indian Centibillionaire

Mukesh Ambani’s fortune surged by approximately $15.3 billion in 2025, bringing his total net worth to $106 billion. This growth was primarily driven by a 27% rally in Reliance Industries (RIL) stock, fueled by investor optimism surrounding the potential IPO of Reliance Jio in 2026 and the group’s expansion into green energy. Ambani remains the only Indian featured on Bloomberg’s global list of the world's 25 richest families.

Lakshmi Mittal: The High-Growth Performer

While Ambani leads in total value, Lakshmi Mittal, the Executive Chairman of ArcelorMittal, has seen the most significant relative jump. Mittal’s wealth soared by $11.7 billion to reach $31.4 billion by late 2025.

  • Growth Driver: A global recovery in steel demand and strategic operational improvements at ArcelorMittal propelled his fortune, making him the second-largest gainer in the Indian billionaire bracket.
  • Relocation News: Interestingly, this wealth surge comes amid reports of Mittal relocating his primary residence from the UK to Dubai or Switzerland due to changing tax environments.

The Adani Recovery

Gautam Adani holds the position of the second-richest Indian with a net worth of $85.2 billion. After a volatile period in previous years, Adani saw his wealth surge by $6.52 billion in 2025. Shares of Adani Power, Adani Ports, and Adani Energy Solutions gained between 23% and 36% this year, stabilizing the group’s overall valuation.

Losers of 2025

The year wasn't favorable for all; IT czars Shiv Nadar and Azim Premji collectively lost nearly $8.8 billion due to a slowdown in global tech spending and a recalibration of tech valuations, placing them among the 10 worst-hit billionaires globally on the Bloomberg index this year.
