The largest bankruptcy in history is Lehman Brothers, the American investment bank that filed for Chapter 11 protection in September 2008 with approximately $691 billion in assets. That single filing remains the biggest corporate collapse on record and triggered a global financial crisis that reshaped banking regulation worldwide.
Understanding the largest bankruptcies ever recorded matters for founders and operators because these cases are not just history lessons. They reveal the exact failure modes that destroy otherwise large, successful organizations: overleveraged balance sheets, unchecked fraud, business model obsolescence, and catastrophic liquidity mismatches. Each collapse carries a transferable warning that applies to companies of any size. The list below ranks 15 cases by total assets at the time of filing, the standard measure used by legal and financial analysts.

The 15 Largest Bankruptcies in History
1. What was the largest corporate bankruptcy in history?
Lehman Brothers Holdings
Total assets at filing: approximately $691 billion (September 2008)
Lehman Brothers was a 158-year-old American investment bank that collapsed after accumulating catastrophic exposure to subprime mortgage-backed securities. When the U.S. government declined to arrange a rescue, the firm filed for Chapter 11 bankruptcy on September 15, 2008, in what remains the largest corporate bankruptcy ever recorded. The filing instantly froze global credit markets and accelerated the 2008 financial crisis.
Takeaway: Even century-old institutions collapse when their assets are illiquid and their liabilities are short-term. Business builders should never fund long-duration assets with short-duration debt.
—
2. How big was the Washington Mutual bankruptcy?
Washington Mutual (WaMu)
Total assets at filing: approximately $328 billion (September 2008)
Washington Mutual was the largest savings and loan institution in the United States before federal regulators seized it and sold its banking operations to JPMorgan Chase for $1.9 billion. The seizure occurred just days after the Lehman Brothers filing, making September 2008 the most destructive month for financial institutions in modern history. WaMu had aggressively expanded into adjustable-rate and subprime mortgages during the housing boom.
Takeaway: Growth strategies that depend entirely on a rising asset market eventually face the market’s reversal. Diversify revenue sources before any single bet becomes existential.
—
3. How large was the WorldCom bankruptcy?
WorldCom
Total assets at filing: approximately $104 billion (July 2002)
WorldCom was a major American telecommunications company whose executives orchestrated one of the largest accounting frauds in U.S. history, inflating earnings by roughly $11 billion through improper expense capitalization. The fraud was uncovered by the company’s own internal auditors, and WorldCom filed for bankruptcy in July 2002. The company later emerged from bankruptcy as MCI before being acquired by Verizon in 2006.
Takeaway: Fraud that inflates reported earnings accelerates collapse rather than preventing it. Founders should build finance teams with genuine independence and clear whistleblower channels.
—
4. What was the General Motors bankruptcy size?
General Motors (GM)
Total assets at filing: approximately $91 billion (June 2009)
General Motors, one of the largest automobile manufacturers in the world, filed for Chapter 11 bankruptcy in June 2009 after decades of rising labor costs, falling market share, and a global credit crunch that made financing unavailable. The U.S. government provided roughly $50 billion in financial support as part of a structured bankruptcy that allowed GM to shed legacy liabilities and emerge as a new entity in just 40 days. GM returned to public markets via an IPO in November 2010.
Takeaway: Legacy cost structures and incumbent complacency create vulnerabilities that external shocks can trigger. Operators should periodically stress-test their cost base against severe revenue declines.
—
5. How big was the CIT Group bankruptcy?
CIT Group
Total assets at filing: approximately $80 billion (November 2009)
CIT Group was a major American commercial lending and leasing company that filed for bankruptcy after the 2008 credit crisis cut off its access to the short-term funding markets it relied on. The firm had been denied government assistance under the Troubled Asset Relief Program (TARP), a U.S. government bank rescue initiative, and its debt load became unmanageable. CIT emerged from bankruptcy in just 40 days with a pre-packaged reorganization plan agreed upon by creditors.
Takeaway: Companies dependent on wholesale funding markets rather than stable deposit bases face immediate collapse when liquidity dries up. Building diversified, sticky funding sources is a structural priority.
—
6. What was the Enron bankruptcy size?
Enron Corporation
Total assets at filing: approximately $65.5 billion (December 2001)
Enron was a Houston-based energy trading and utilities company that used complex off-balance-sheet vehicles to hide billions in debt and inflate reported profits. When the concealed liabilities were revealed in late 2001, creditor confidence collapsed and the company filed for bankruptcy in December 2001, at the time the largest bankruptcy in U.S. history. The Enron scandal directly prompted the Sarbanes-Oxley Act of 2002, which overhauled U.S. corporate governance and accounting disclosure rules.
Takeaway: Complex financial structures that obscure the true state of a business eventually surface and destroy trust completely. Transparency with investors and creditors is a long-term competitive asset.
—
7. How large was the Conseco bankruptcy?
Conseco
Total assets at filing: approximately $61 billion (December 2002)
Conseco was an American insurance and financial services holding company that collapsed under the weight of $7 billion in debt accumulated through an aggressive acquisition strategy. The company had purchased Green Tree Financial, a subprime mobile home lender, for $6 billion in 1998, a deal that generated massive write-downs as the mobile home loan market deteriorated. Conseco emerged from bankruptcy in 2003 and was rebranded as Bankers Life and Casualty.
Takeaway: Acquisition-driven growth strategies that use excessive debt leave no room for asset underperformance. Acquirers should model downside scenarios before any deal closes.
—
8. What was the MF Global bankruptcy?
MF Global Holdings
Total assets at filing: approximately $41 billion (October 2011)
MF Global was a global futures and derivatives broker that collapsed after its chief executive, Jon Corzine, made a large directional bet on European sovereign debt, specifically bonds issued by troubled eurozone governments. When the position moved against the firm and liquidity demands rose, MF Global was found to have improperly used approximately $1.6 billion in customer segregated funds. The firm filed for bankruptcy in October 2011, triggering one of the most significant regulatory investigations in commodities trading history.
Takeaway: Using client funds or assets to cover proprietary losses is both illegal and an irreversible trust destruction event. Strict operational separation between firm capital and customer capital is non-negotiable.
—
9. How big was the Chrysler bankruptcy?
Chrysler LLC
Total assets at filing: approximately $39 billion (April 2009)
Chrysler, one of the three major American automakers, filed for Chapter 11 bankruptcy in April 2009, weeks before General Motors did the same. The U.S. and Canadian governments provided financial support as part of a structured sale of most assets to Fiat S.p.A., the Italian automaker, which formed Fiat Chrysler Automobiles. Chrysler’s bankruptcy was processed in just 42 days, one of the fastest reorganizations of a company that size on record.
Takeaway: Speed of reorganization can preserve more enterprise value than a prolonged restructuring. Pre-negotiating creditor agreements before filing materially compresses bankruptcy timelines.
—
10. What was the Thornburg Mortgage bankruptcy?
Thornburg Mortgage
Total assets at filing: approximately $36.5 billion (May 2009)
Thornburg Mortgage was a U.S. residential mortgage lender that specialized in jumbo mortgages, home loans above the conforming loan limit, for high-credit-quality borrowers. Despite its relatively conservative lending profile, Thornburg was fatally exposed to margin calls on its mortgage-backed securities portfolio when the credit crisis reduced the value of those assets. The firm could not raise liquidity fast enough to meet its obligations and filed for bankruptcy in May 2009.
Takeaway: Even a high-quality asset portfolio creates liquidity risk when it is pledged as collateral on margin-callable financing. Stress-test collateral arrangements against sudden price dislocations.
—
11. How large was the Pacific Gas and Electric bankruptcy?
Pacific Gas and Electric (PG&E)
Total assets at filing: approximately $36 billion (January 2019)
PG&E is the largest investor-owned utility in the United States, serving much of Northern California. The company filed for bankruptcy in January 2019 after facing an estimated $30 billion in potential liability related to its power lines being linked to a series of devastating California wildfires, including the 2018 Camp Fire that destroyed the town of Paradise. PG&E emerged from bankruptcy in June 2020 after reaching settlement agreements with wildfire victims and insurance companies.
Takeaway: Unquantified and uninsured liability exposure can grow to exceed a company’s total equity value. Operators in industries with catastrophic tail risks should assess those exposures continuously and explicitly.
—
12. What was the Texaco bankruptcy?
Texaco
Total assets at filing: approximately $35.9 billion (April 1987)
Texaco was one of the largest oil companies in the United States when it filed for bankruptcy in April 1987, not because of operational failure but because of a $10.53 billion legal judgment won by Pennzoil. A Texas jury ruled that Texaco had improperly interfered with Pennzoil’s acquisition of Getty Oil, and the resulting judgment threatened to seize Texaco’s assets before an appeal could be heard. The bankruptcy protected Texaco from asset seizure and it ultimately settled with Pennzoil for $3 billion.
Takeaway: Single legal judgments can threaten a solvent, profitable company. Businesses operating in environments with large punitive damage exposure need robust litigation risk management.
—
13. How big was the Financial Guaranty Insurance Company bankruptcy?
Financial Guaranty Insurance Company (FGIC)
Total assets at filing: approximately $26 billion (August 2010)
FGIC was an American bond insurer that had guaranteed payments on municipal bonds and mortgage-backed securities. When the securities it insured defaulted during the 2008 credit crisis, FGIC faced claims far beyond its capital reserves and was placed into rehabilitation by New York regulators in 2012, following an earlier 2010 filing. The collapse of bond insurers like FGIC removed a layer of protection that municipal bond investors had relied on for decades.
Takeaway: Insurance and guarantee business models carry low visible risk during calm markets but can face correlated, simultaneous claims in a systemic crisis. Model correlation risk explicitly, not just average-case claims.
—
14. What was the Refco bankruptcy?
Refco
Total assets at filing: approximately $33 billion (October 2005)
Refco was one of the largest futures and commodities brokers in the United States when it disclosed, just weeks after its initial public offering, that its chief executive had concealed $430 million in bad debts owed to the company through a series of circular transactions with related parties. The disclosure triggered an immediate customer run, and Refco filed for bankruptcy within days. The IPO had been completed in August 2005, making the collapse one of the fastest post-IPO failures in U.S. history.
Takeaway: Concealed related-party transactions are a high-severity red flag during due diligence for acquisitions, investments, and partnerships. Verify the independence and arms-length nature of all significant counterparty relationships.
—
15. How large was the Bed Bath and Beyond bankruptcy?
Bed Bath and Beyond
Total assets at filing: approximately $4.4 billion (April 2023)
Bed Bath and Beyond was a large American home goods retail chain that operated more than 700 stores at its peak. The company filed for bankruptcy in April 2023 after years of declining same-store sales, failed attempts to expand private-label merchandise, and a capital allocation strategy that spent roughly $12 billion on share buybacks between 2004 and 2021 rather than reinvesting in stores or digital capabilities. Its brand and intellectual property were acquired by Overstock.com, which rebranded its e-commerce site under the Bed Bath and Beyond name.
Takeaway: Returning capital to shareholders through buybacks while underinvesting in core operations and digital transformation is a recognized pathway to retail obsolescence. Operators should benchmark reinvestment rates against competitive shifts in their category.

FAQ: Largest Bankruptcies in History
What counts as the largest bankruptcy ever filed?
Bankruptcies are ranked by total assets at the time of filing, not by liabilities or losses suffered. By that standard, Lehman Brothers, with approximately $691 billion in assets, is the largest bankruptcy ever filed.
Do large companies usually survive bankruptcy?
Many do, through a restructuring process called Chapter 11 in the United States, which allows a company to reorganize debts while continuing to operate. General Motors, Chrysler, and Enron all emerged from bankruptcy in some form, though shareholders in the original entities typically received little or nothing.
What industries appear most in large bankruptcy lists?
Financial services, including banks, brokers, and insurers, account for the largest bankruptcies by asset size because these firms hold massive balance sheets relative to their equity. Automotive, energy, and retail also appear frequently, reflecting capital intensity and vulnerability to demand shifts and commodity cycles.
What is the difference between Chapter 7 and Chapter 11 bankruptcy?
Chapter 11 is a reorganization process where a company restructures its debts and continues operating, while Chapter 7 is a liquidation process where a company’s assets are sold to repay creditors and the business ceases to exist. Most large corporate bankruptcies in this list were Chapter 11 filings.

The Business Model Analyst Take
The single most consistent pattern across every major bankruptcy on this list is a mismatch between the risk that management believed it was carrying and the risk that actually existed on the balance sheet. Lehman did not believe its mortgage assets would fall as far as they did. Enron’s executives convinced themselves that complex structures were sustainable. GM assumed its cost base was manageable until it was not.
The practical implication for founders and operators is straightforward: the purpose of financial modeling is not to produce a number to report to investors. It is to surface the hidden assumptions in your business that, if wrong, will kill the company. Run the downside cases. Ask what a 40 percent revenue decline looks like. Ask what happens when your primary funding source closes. Ask what a single large legal judgment does to your solvency. The companies on this list did not ask those questions seriously enough, and that is the real reason they appear here.
