Mukesh Ambani, chairman and managing director of Reliance Industries, has emerged as the world’s biggest billionaire wealth gainer after his estimated net worth increased by approximately $6.3 billion on November 2, 2026. The sharp rise followed a major rally in Reliance Industries shares after the company reported stronger-than-expected financial results for the September quarter.
According to Forbes’ Real-Time Billionaires ranking, Ambani’s estimated fortune reached around $88.8 billion, placing him at No. 23 among the world’s richest people. His wealth increased by approximately 7.85% in the latest reported snapshot, putting him well ahead of other billionaires on the daily gainers list. The exact daily gain varied slightly across Forbes updates, with an earlier snapshot showing an increase of approximately $6.2 billion.
Reliance Industries Shares Drive Ambani’s Wealth Increase
The primary reason behind Ambani’s wealth increase was the sharp rise in Reliance Industries shares. The company’s stock gained 11.6% on November 2, recording its strongest single-day performance in more than six years.
The rally followed Reliance Industries’ September-quarter results, which showed a substantial improvement in profitability. Investors responded positively to stronger earnings from its oil-to-chemicals business and continued growth in digital services.
Reliance shares closed at ₹1,300 on the day, compared with the previous closing price of ₹1,164.90. The stock was also the biggest positive contributor to the Nifty 50’s advance, accounting for a significant portion of the benchmark index’s gains.
The rally helped increase the market value of Reliance Industries and raised the estimated value of Ambani’s stake in the company. Since a substantial portion of his wealth is linked to Reliance, movements in the company’s share price can have a significant impact on his position in billionaire rankings.
Reliance Industries Reports Strong Q2 FY27 Results
Reliance Industries reported strong financial performance for the quarter ended September 30, 2026. Its consolidated gross revenue increased 27.8% year-on-year to ₹3,62,268 crore, while EBITDA rose 23.9% to ₹62,409 crore.
The company also reported a record quarterly profit after tax, including its share of profits from associates and joint ventures, of ₹29,550 crore, up 33.8% from the corresponding period last year.
Profit attributable to the owners of the company increased approximately 40.6% to ₹25,548 crore, compared with ₹18,165 crore in the year-ago quarter.
| Financial metric | Q2 FY27 | Year-on-year change |
|---|---|---|
| Gross revenue | ₹3,62,268 crore | +27.8% |
| EBITDA | ₹62,409 crore | +23.9% |
| EBITDA margin | 17.2% | -60 basis points |
| Profit after tax, including associates and JVs | ₹29,550 crore | +33.8% |
| Profit attributable to owners | ₹25,548 crore | +40.6% |
The results highlighted stronger performance across major parts of Reliance’s business, particularly its oil-to-chemicals and digital services operations.
Oil-to-Chemicals Business Leads Earnings Growth
Reliance’s oil-to-chemicals (O2C) business was a major contributor to the improvement in quarterly earnings. The segment benefited from stronger transportation fuel margins and improved petrochemical profitability.
O2C EBITDA reached ₹25,203 crore, increasing 67.9% year-on-year. This was one of the strongest performances in the segment in recent quarters.
The improvement was supported by better refining economics and stronger margins across parts of the petrochemical business. These conditions helped Reliance convert favourable global market conditions into higher operating earnings.
The performance is particularly important because the O2C business remains one of Reliance’s largest sources of revenue and operating profit. Changes in crude oil prices, refining margins, transportation fuel demand and petrochemical spreads can significantly influence the company’s financial performance.
Jio Platforms Adds to Reliance’s Growth Story
Reliance’s digital services business also contributed to the stronger quarterly performance.
Jio Platforms reported EBITDA of ₹22,223 crore, representing a 17.7% increase compared with the corresponding quarter last year. Growth in digital services and telecom operations supported the segment’s earnings.
Jio’s contribution has become increasingly important as Reliance expands beyond its traditional oil and petrochemicals businesses. The company has been developing its digital ecosystem through mobile connectivity, broadband services, enterprise solutions and digital platforms.
Jio Platforms’ capital-market debut in October 2026 also brought additional attention to the value of Reliance’s digital business. The listing has provided investors with a more direct way to assess the business and its contribution to the wider Reliance group.
Ambani Leads Other Billionaire Gainers
Ambani’s estimated wealth increase was significantly larger than the gains recorded by other billionaires on Forbes’ daily gainers list.
The November 2 snapshot reported the following leading gainers:
| Rank | Billionaire | Approximate daily wealth gain |
|---|---|---|
| 1 | Mukesh Ambani | $6.3 billion |
| 2 | Amancio Ortega | $1.7 billion |
| 3 | Zhong Shanshan | $1.5 billion |
The figures are based on reported snapshots of Forbes’ real-time ranking and may change as market prices and valuations are updated.
Ambani’s position at No. 23 globally also made him the highest-ranked Indian billionaire in the latest reported list. Gautam Adani was ranked No. 26, with an estimated fortune of approximately $79.1 billion in the same update.
It is important to distinguish this daily ranking from Forbes’ annual India Rich List. The annual 2026 list, published in September, had placed Adani ahead of Ambani based on wealth measured at an earlier market date. Real-time rankings can produce different positions as share prices change.
Why Forbes’ Billionaire Rankings Change Every Day
Forbes’ Real-Time Billionaires list tracks changes in the estimated wealth of the world’s richest individuals. It uses publicly available information about shareholdings, company valuations and other assets to calculate their net worth.
For publicly traded investments, Forbes updates valuations frequently when the relevant stock markets are open. Its methodology specifies that public-holding values are updated every five minutes, with a 15-minute delay in stock prices. Wealth linked to private companies is generally updated once a day.
The daily gainers ranking compares estimated fortunes with the previous trading day’s market close. Consequently, a sharp movement in a major company’s share price can quickly change its owner’s position on the list.
However, a billionaire’s estimated wealth is not the same as cash income. A rise in net worth does not mean the individual has received that amount in cash or sold shares to realise the gain. It primarily represents an increase in the estimated market value of assets.
The Bigger Picture
Ambani’s latest wealth increase highlights the influence that large listed companies have on billionaire rankings. Reliance Industries operates across several major sectors, including energy, petrochemicals, retail, telecommunications and digital services. Its diversified business model means that changes in different industries can influence its earnings and valuation.
The rally also reflects investor confidence in Reliance’s latest financial performance, particularly the recovery in its O2C business and the continued growth of Jio. However, the company’s retail profitability remains an area investors will continue to monitor, while its energy and digital investments require significant execution over the coming years.
Looking Ahead
Reliance Industries’ future valuation will depend on whether it can sustain its earnings momentum across its major businesses. Refining margins, petrochemical demand, telecom growth, retail profitability and the execution of new energy and technology investments will remain important factors for investors.
For Ambani, the latest jump demonstrates how closely his estimated fortune is connected to Reliance’s stock-market performance. The $6.3 billion increase places him at the top of Forbes’ daily billionaire gainers list, but his position and estimated net worth may change again as markets move and Forbes updates its calculations.
