In 2008, Anil Ambani was the sixth-richest person in the world, with Forbes estimating his fortune at about $42 billion. He controlled a sprawling business empire spanning telecommunications, power, infrastructure and financial services, and appeared to have inherited one of the most powerful positions in Indian business. Twelve years later, the same billionaire was fighting a lawsuit in a London court and saying his net worth was effectively zero after accounting for his liabilities. Between those two moments came a family split, an enormous expansion, a telecom war, billions in borrowing and the collapse of companies that had once seemed almost unstoppable.
He Was One Of The Richest Men In The World
Anil Ambani did not build his fortune from nothing. He was the younger son of Dhirubhai Ambani, the founder of Reliance Industries, one of India’s most powerful business groups. When Dhirubhai died in 2002 without leaving a will, his sons Mukesh and Anil inherited positions at the center of a huge corporate empire. At the time, Reliance Industries was valued at roughly Rs 28,000 crore, and the brothers initially remained within the same organization.
That arrangement did not last. Tensions between the brothers eventually became impossible to contain, and in 2005 the Reliance empire was divided between them. Mukesh retained the oil-refining and petrochemicals businesses, while Anil received telecommunications, power generation and financial services. The two sides also agreed to a non-compete arrangement that temporarily prevented them from entering each other’s principal sectors.
On paper, Anil had received an extraordinary collection of businesses. Telecom was one of India’s fastest-growing industries, power demand was enormous and financial services offered opportunities for further expansion. His Reliance Group would eventually include Reliance Communications, Reliance Power, Reliance Capital, Reliance Infrastructure and other major businesses.
For a time, the strategy appeared to work spectacularly well. In 2008, Forbes placed Anil Ambani sixth on its list of the world’s richest people, estimating his wealth at approximately $42 billion. He was no longer simply the younger son of a famous industrialist. He had become one of the world’s wealthiest businessmen in his own right.
But much of that wealth was tied to the value of his companies. And the companies he controlled would soon need enormous amounts of capital to keep growing.

Then He Bet Big On Telecom
The most important company in Anil’s empire was Reliance Communications, usually known as RCom. The business had enormous ambitions and entered the Indian telecom market at a time when millions of new consumers were beginning to acquire mobile phones. But the technology choice that initially seemed promising would eventually become a serious disadvantage.
RCom began with CDMA technology, while major competitors such as Airtel and Hutch were using GSM. As the industry developed, the technological landscape shifted. When the market moved toward 4G, RCom found itself increasingly disadvantaged, while competitors were fighting aggressively for subscribers and driving prices downward.
Telecommunications is also an unusually capital-intensive business. Networks require constant investment in towers, spectrum, infrastructure and technology, and companies cannot simply stop spending when competition becomes intense. Anil continued trying to expand RCom, making investments and pursuing deals while the industry’s economics were becoming increasingly difficult.
That created a dangerous cycle. Expansion required more money. More money meant more borrowing. More borrowing created larger obligations, which meant the company needed even greater scale and profitability to justify the investment. As competition intensified and prices fell, the room for error became smaller. Then Anil’s most formidable competitor entered the same industry.
His Brother Became His Rival
The brothers’ non-compete agreement eventually expired in 2010, removing one of the barriers that had kept Mukesh Ambani out of telecommunications. Mukesh acquired Infotel Broadband and began preparing for a major return to the sector. A few years later, his plans would transform the Indian telecom market.
In 2016, Reliance Jio entered the market with an extraordinarily aggressive strategy. Its arrival triggered a brutal price war and forced established operators to respond to dramatically lower prices and changing consumer expectations. Companies that had once operated in a rapidly expanding market now faced an entirely different competitive environment.
For RCom, the timing was devastating. The company was already carrying substantial debt and dealing with the technological disadvantages of its earlier network strategy. Now it faced a competitor backed by the financial resources of Mukesh Ambani’s much stronger Reliance empire.
Anil attempted to find a way out. There was even a proposed deal under which RCom’s assets would be sold to Jio, potentially allowing the company to reduce its debt and escape its worsening position. But the transaction ultimately fell apart after India’s telecom department required Jio to assume responsibility for certain dues, something Mukesh was not willing to accept. The company that had once been the crown jewel of Anil’s empire was running out of options.
The Debt Started Catching Up With Him
RCom shut down its wireless operations in 2017 as losses and debt continued to grow. Anil then turned toward asset sales and debt-resolution plans, hoping that parts of the wider Reliance Group could be sold or restructured before the problems became irreversible.
But the telecom crisis was no longer confined to one company. Reliance Capital was also dealing with financial-sector difficulties and began selling assets in an effort to reduce its debt. Reliance Home Finance and Reliance Commercial Finance faced their own financial pressures, while the group’s infrastructure and power businesses were also struggling with debt obligations.
The scale of the problem became increasingly difficult to hide. By December 2019, companies including Reliance Communications, Reliance Naval & Engineering, Reliance Infrastructure and Reliance Power had defaulted on loans totaling more than Rs 43,800 crore, according to The News Minute’s reporting at the time. Reliance Naval had entered insolvency proceedings, while RCom’s undersea-cable subsidiary Global Cloud Xchange had also sought bankruptcy protection in the United States.
The numbers were now moving in the opposite direction from the ones that had made Anil famous. In 2008, Forbes had estimated his wealth at $42 billion. By 2020, the businesses supporting that fortune were being sold, restructured or pushed into insolvency. And then the consequences reached him personally.
The Billionaire Ended Up In A London Court
The most dramatic moment came not in Mumbai, but in London.
Three Chinese state-controlled banks were pursuing Anil Ambani over a loan made to Reliance Communications in 2012. The banks argued that the loan, originally around $925 million, had been personally guaranteed by Ambani. After RCom defaulted, the lenders sought to recover hundreds of millions of dollars, including interest.
In court filings, Ambani said the value of his investments had collapsed. His shareholdings were worth only around $82.4 million at the time, he said, and after taking his liabilities into account, his net worth was zero. He also argued that he did not possess meaningful assets that could be liquidated for the purposes of the proceedings. The statement was extraordinary because of who was making it. This was the same man Forbes had once ranked as the sixth-richest person on Earth.
A decade earlier, he had appeared to have almost unlimited financial power. Now he was arguing in a London courtroom that his assets could not meaningfully cover the liabilities being pursued against him.
The court did not simply accept that position. In February 2020, a judge ordered Ambani to deposit $100 million while the dispute proceeded, rejecting his argument that his net worth was effectively zero for purposes of the case. The distance between those two worlds could hardly have been greater.
The Brother He Fought Helped Save Him
There is another twist that makes the Ambani story more complicated than a simple tale of sibling rivalry.
By 2019, Anil’s financial problems had become severe enough that the Supreme Court of India threatened to imprison him over unpaid dues owed by RCom to Ericsson India. The court gave him a short deadline to make the payment.
Then Mukesh stepped in.
The elder brother who had become Anil’s most formidable competitor in telecommunications paid the amount needed to prevent his younger brother from going to jail. The payment reportedly came at the last moment, bringing an extraordinary family story full circle: the man whose entry into telecom had helped transform the competitive environment around RCom was also the man who intervened when Anil faced an immediate personal legal crisis.
It is tempting to reduce the story to a battle between two brothers, but that would miss the larger lesson. Their fortunes diverged because the businesses they controlled were fundamentally different in their capital requirements, competitive positions and ability to generate cash. The family relationship made the contrast more dramatic, but it was not the sole explanation for what happened. By then, however, the decline of Anil’s empire had become impossible to ignore.
One Empire Had Become Two Completely Different Stories
The split of the Reliance empire had created two enormous business groups, but the years that followed produced radically different outcomes.
Mukesh’s businesses were anchored in refining and petrochemicals before expanding aggressively into telecommunications and digital services. Anil’s portfolio was spread across sectors that required substantial capital and faced difficult market conditions, including telecom, power, infrastructure, financial services and defense-related manufacturing. That distinction mattered.
Businesses that require constant investment can produce spectacular growth when financing is cheap and markets are expanding. But the same structure can become dangerous when competition intensifies, revenues fall or debt becomes too large. A company can still own valuable assets and have ambitious plans while simultaneously becoming less capable of servicing the obligations it accumulated during its expansion.
That appears to have been one of the central problems facing Anil’s group. His businesses were not collapsing because they suddenly became worthless overnight. They were being squeezed by a combination of high debt, intense competition, difficult economic conditions, technological change and the need to keep investing.
Once that cycle turned negative, selling assets became less about funding the next stage of growth and more about trying to survive.
What Really Destroyed The Fortune?
There was no single moment when Anil Ambani lost $42 billion. The number represented the market value of his holdings at a particular point in time, and that value could rise or fall as the companies performed. His later claim of having a net worth of zero referred to his financial position after taking liabilities into account.
The deeper story was about leverage.
Anil had received businesses with enormous potential, but many required continual investment to remain competitive. Telecom was especially unforgiving. RCom faced technological disadvantages, falling prices and increasingly aggressive competitors, while its expansion strategy required more capital. When the expected growth failed to produce enough returns, the debt remained.
Then similar pressures appeared elsewhere in the group. Financial services were hit by a broader sector crisis, infrastructure and power businesses struggled with their own obligations, and Reliance Naval entered insolvency proceedings. By the end of 2019, several major companies connected to Anil’s group had defaulted on substantial loans.
The lesson is therefore more complicated than “a billionaire made a bad investment.”
The real danger was an empire built around businesses that needed enormous amounts of capital to keep growing, combined with debt that became increasingly difficult to service when the underlying economics changed. Ambition had created scale. Debt had financed the ambition. And when growth stopped being enough, the debt remained.
The Man Who Had Everything Was Suddenly Fighting To Prove He Had Nothing
By 2020, the transformation was almost impossible to comprehend.
Anil Ambani had once appeared on lists of the world’s richest people with a fortune estimated at $42 billion. His companies had operated across some of India’s most important industries, and his name carried the weight of one of the country’s most powerful business families.
Now he was sitting in a London legal battle involving hundreds of millions of dollars and arguing that his investments had collapsed in value and that his liabilities left him with no meaningful net worth. The banks seeking repayment disputed his position, and the court ordered him to put $100 million into court while the case proceeded. That contrast is what makes his story so compelling.
It is not simply a story about a rich man becoming poorer. It is about the difference between wealth on paper and financial strength in reality.
At the height of a bull market, rising share prices can make an entrepreneur appear extraordinarily wealthy. But if those shares are tied to companies carrying enormous debts, falling valuations can destroy the apparent fortune much faster than most people imagine. Anil Ambani’s story became one of the most dramatic examples of that distinction.
The Fortune Did Not Disappear Overnight
Looking backward, the collapse can appear almost instantaneous: $42 billion in 2008, virtually nothing by 2020.
But the underlying decline took years.
RCom’s competitive problems developed gradually. Debt accumulated through repeated expansion and investment. The arrival of Jio intensified the pressure. Attempts to sell assets and restructure debt failed to solve the larger problem. Other businesses began experiencing their own financial difficulties, and eventually insolvency and legal battles followed.
That is perhaps the most important part of the story.
Great fortunes rarely disappear in a single dramatic moment. They often erode through a series of decisions that each seem manageable when viewed separately. Borrow a little more to expand. Invest a little more to stay competitive. Sell one asset to pay another debt. Delay the inevitable restructuring. Hope the market improves. Then one day, the numbers no longer work.
For Anil Ambani, that day arrived after years of expansion had turned into years of debt reduction, asset sales, defaults and legal battles.
From $42 Billion To A Courtroom
The image that remains is not necessarily the most famous photograph of Anil Ambani at the height of his wealth.
It is the contrast.
A businessman once ranked sixth among the world’s richest people was later required to explain his finances before a London court. The man who had once controlled an enormous corporate empire was now saying that his investments had collapsed and that his liabilities left him with no meaningful net worth.
His story also shows how quickly two fortunes can diverge even when they begin in the same family.
Mukesh and Anil Ambani started with the same father, the same corporate legacy and the same enormous business opportunity. Yet after the 2005 split, their paths moved in radically different directions. One brother built an increasingly valuable conglomerate and expanded into one of the world’s most consequential telecom markets. The other watched a debt-heavy empire unravel across several industries. The difference was not simply luck.
It was the result of business choices, market timing, technology, competition, financing and the brutal mathematics of debt.
In 2008, Forbes estimated Anil Ambani’s fortune at $42 billion, making him the sixth-richest person in the world. Twelve years later, he told a London court that his net worth was effectively zero after accounting for his liabilities. Between those moments, the Reliance empire was split, RCom accumulated debt, Mukesh Ambani entered telecom with Jio, competition intensified and several of Anil’s businesses fell into financial distress. His fortune did not vanish overnight. It was gradually consumed by the difficult economics of an empire built on expansion, investment and debt.
This story draws primarily on The News Minute’s account of Anil Ambani’s financial collapse, supplemented by contemporary reporting on the London court case, the RCom debt crisis and the Ericsson dispute. The original reporting is particularly useful for understanding how the 2005 split of the Reliance empire eventually produced two dramatically different business trajectories.
