Top 10 Biggest Business Failures in History

Theranos promised to revolutionize blood testing with a finger-prick device capable of 200+ tests on a single drop, reaching a $9 billion valuation in 2014 and making founder Elizabeth Holmes the youngest self-made female billionaire. The technology was a complete fraud—samples were secretly run on conventional machines. Holmes was convicted of criminal fraud in 2022 and sentenced to 11 years in prison. While Theranos's $9 billion valuation collapse was far smaller than WorldCom's $180 billion loss, its impact on Silicon Valley trust was profound, exposing how charisma and hype can bypass due diligence.

FTX's $32 billion collapse remains the crypto industry's largest fraud conviction. In November 2022, the exchange secretly diverted $8 billion in customer deposits to cover losses at its sister hedge fund Alameda Research. Founder Sam Bankman-Fried, once a leading political donor, was convicted on seven counts of fraud and sentenced to 25 years in prison. The implosion occurred in just nine days—four times faster than the gradual decline of WeWork (#6), which took years from peak valuation to bankruptcy filing. This rapid unraveling erased $1.2 billion in venture capital funding overnight.

WeWork's $47 billion valuation collapse is the defining startup cautionary tale of the 2010s. The co-working company raised $12.8 billion from SoftBank, then saw its IPO fail amid $1.9 billion in annual losses and founder Adam Neumann's erratic self-dealing, including leasing buildings he personally owned. By 2023, it filed for bankruptcy, ending with a market cap near zero; Neumann received a $1.7 billion golden parachute. That payout is 3.3 times larger than the $5.3 billion debt load that doomed Toys "R" Us (#8), highlighting how founder enrichment outpaced creditor recovery.

Kodak's 131-year dominance ended with a textbook case of innovator's dilemma. The company controlled 90% of US film sales, invented the digital camera in 1975, but refused to commercialize it to protect film profits. By 1997, its stock peaked at $94.25; by 2011, it traded below $1. Digital cameras and smartphones wiped out film, leading to a 2012 bankruptcy that eliminated 140,000 jobs—more than four times the 33,000 jobs lost at Toys "R" Us (#8). The company's failure to pivot cost shareholders $28 billion in lost market value.

Toys "R" Us's 2018 liquidation of all 800 US stores ended a 70-year retail institution. Saddled with $5.3 billion in debt from a 2005 leveraged buyout by KKR, Bain Capital, and Vornado Realty, the chain couldn't compete with Amazon's pricing and convenience, costing 33,000 jobs. That debt burden was 3.1 times the $1.7 billion golden parachute of WeWork's founder (#6), making private equity's role a rallying cry for reform. The buyout firms extracted $470 million in fees before the bankruptcy, leaving creditors with just 14 cents on the dollar.

Nokia's fall from the world's #1 phone maker (controlling 40% of the global mobile phone market in 2007) to irrelevance by 2013 is the most dramatic collapse in technology history. Having dominated the mobile era for a decade, Nokia failed to respond to the iPhone's 2007 touchscreen revolution. Internal culture problems, bureaucracy, and reluctance to adopt new operating systems led to its mobile phone business being sold to Microsoft for $7.2 billion in 2013 — a fraction of its peak value.

Bed Bath & Beyond's 2023 bankruptcy eliminated a 52-year-old American retail institution that had once dominated the home goods category with 1,500 stores and $12 billion in peak revenue. The company spent $11.8 billion on stock buybacks between 2004 and 2019 — money that could have funded digital transformation and store modernization — instead enriching shareholders while gutting its competitive position. Its meme stock moment in 2022 briefly revived its stock before the inevitable collapse.
