Top 15 startup collapses by capital destroyed
USD millions — peak valuation / total funding wiped out.
The Top 10 — by Value Destroyed
The single decisions, products, or scandals that vaporized the most capital in startup history.
Silicon Valley Bank (SVB)
Concentration risk in a single industry can create correlated failure modes, making a business vulnerable to market shifts.
BitMEX
You cannot build a financial empire by deliberately evading regulations. BitMEX's founders chose offshore structures over compliance and paid with criminal convictions.
Terraform Labs (Terra/Luna)
Algorithmic stablecoins backed by their own volatile sister token are reflexive ponzis waiting to unwind. Yield that high implies risk that high.
WeWork
Valuation hype cannot mask fundamentally broken unit economics. Corporate governance failures amplify founder risk.
FTX
Due diligence on founder character is as important as business metrics. Lack of corporate governance enabled massive fraud.
Wirecard
Even DAX-30 companies with Big Four auditors can be complete frauds. Wirecard proved that regulatory capture and national pride can blind everyone to obvious red flags.
Byju's
Aggressive acquisition-driven growth funded by debt is fragile. Transparency with investors is non-negotiable.
Didi (DiDi Global)
Going public in the US against your home government's wishes can trigger an existential regulatory response that no amount of funding can overcome.
Juul Labs
A $38B e-cigarette company that hooked teenagers on nicotine faced total regulatory destruction.
Northvolt
Manufacturing battery cells at scale is extraordinarily hard. Even $13.8B couldn't bridge the gap between lab results and factory output.
Anatomy of a Mega-Failure
Four stages, every time. Once you see the pattern, you can spot it in real-time inside any pitch deck.
The Vision
A founder pitches a world-changing narrative so compelling it overrides scrutiny.
Adam Neumann sold WeWork as a tech company, not office sublets — at a $47B peak.
The Overfunding
A capital flood masks broken unit economics and silences difficult questions.
SoftBank put $375M into Zume's pizza robots at a $2.25B valuation. Neither business worked.
The Cracks
Whistleblowers, journalists, or a single product failure expose the gap between story and reality.
CoinDesk surfaced Alameda's balance sheet — FTX collapsed in 10 days.
The Collapse
Liquidity vanishes, leverage unwinds, customers withdraw — value is destroyed in days, not quarters.
Terra/Luna vaporized ~$60B in 72 hours when UST broke its peg.
The Eras of Collapse
Each economic regime produced its own signature failure. The pattern repeats — only the buzzwords change.
Burned cash to acquire customers below cost. The internet was real; their businesses weren't.
Cleantech bet on government and commodity prices. Cheap Chinese solar killed the unit economics.
Free money inflated valuations; tightening rates exposed missing fundamentals. ~$200B+ destroyed.
Consumer health and first-gen AI startups hit reality: data risk, no recurring revenue, brutal incumbent response.

Grab Holdings
Building a super-app across fragmented Southeast Asian markets with ride-hailing, delivery, and fintech requires massive capital and patience — profitability may take a decade or more.
$12B
2012–2024
SunEdison
The largest renewable energy bankruptcy in history ($16.1B in debts) was caused by reckless acquisitions financed with unsustainable debt structures.
$12B
1959–2016
Three Arrows Capital (3AC)
Borrowed conviction blows up faster than borrowed capital. Concentrated leveraged bets on reflexive assets are not "risk management."
$10B
2012–2022
Rivian (Value Destruction)
Rivian IPO'd at $150B — briefly worth more than Ford and GM. The stock fell 90% as production couldn't match hype.
$10B
2009–2024
C3.ai
C3.ai is what happens when enterprise AI promises outpace enterprise adoption. Despite a billionaire founder and a $10B IPO valuation, revenue barely grew while the stock lost 85%+.
$10B
2009–2024
Fastly
Fastly was the 'developer-friendly CDN' that rode TikTok's growth to a $10B market cap. When TikTok optimized its CDN spend, Fastly lost its largest customer and 85% of its stock value.
$10B
2011–2024
Theranos
Technology claims must be independently verified. Board composition matters—Theranos had zero biotech experts.
$9B
2003–2018
N26 US
European fintech success doesn't automatically translate to the US market. N26's failure in America shows that regulatory environments, competitive landscapes, and customer expectations differ dramatically.

2013–2022
SmileDirectClub
Disrupting a regulated profession means inheriting that profession's liability — without the political cover to absorb it.
$8.9B
2014–2023
Ezubao
Beware of investment platforms promising unusually high, fixed returns, especially if they lack transparency and independent verification of projects.
$7.6B
2014–2016
Greensill Capital
Supply chain finance works when risk is diversified. Greensill concentrated exposure on a few troubled borrowers and relied on a single insurer — creating a house of cards.
$7B
2011–2021
DataRobot
AutoML was a brilliant concept when data science was scarce. But as AI tools became ubiquitous and cloud providers offered their own AutoML, DataRobot's $6.3B valuation evaporated.
$6.3B
2012–2024
23andMe
A one-time-purchase consumer business cannot sustain a public-company cost structure. A brand cannot survive losing the data.
$6B
2006–2025
Byju's
Growth at all costs through aggressive M&A and high customer acquisition without sustainable unit economics is a recipe for disaster, especially when product-market fit is superficial.
$6B
2011–2025
LeEco
Vertical integration only creates value with control over scarce resources or cost advantages, neither of which LeEco possessed across its vast, capital-intensive ecosystem.
$6B
2004–2017
WM Motor
Capital-intensive hardware businesses require a massive minimum viable scale and aligned capital structure, which WM Motor failed to achieve despite significant funding.
$5.8B
2015–2023
Getir (Detailed)
Instant grocery delivery requires such massive subsidies per order that even $5.5B in funding can't bridge the gap to profitability.
$5.5B
2015–2024
Baoneng
Massive capital injection cannot substitute for deep operational expertise and patience required in complex hardware manufacturing like automotive.
$5.2B
2017–2024
Xingsheng Youxuan
Standalone community group-buying platforms in low-margin categories with poor unit economics are unsustainable without a profitable adjacent business to cross-subsidize losses.
$5.2B
2018–2025
YOOX Net-A-Porter (Richemont Write-Down)
Milan-founded luxury e-commerce pioneer YOOX-Net-A-Porter was written down by Richemont by €2.7B in 2023 then sold to Mytheresa at a near-zero price — the largest Italian e-commerce value destruction.

What the Biggest Failures Share
Massive Overfunding
Average company on this list raised $23B in implied value at peak. Excessive capital masked broken economics and silenced internal critics. SoftBank alone appears in 6+ entries.
Governance Failures
Weak boards, no independent oversight, charismatic founders with unchecked power. FTX had no board. WeWork's board let Neumann cash out $700M. 23andMe's entire independent board resigned in 2024 over the Wojcicki go-private offer.
Growth Over Profit
Every company prioritized top-line growth over sustainable unit economics. "Blitzscaling" rewarded burning cash for market share — until interest rates rose and investors demanded profitability the businesses couldn't produce.
Founder Mythology
Charismatic storytellers — SBF, Elizabeth Holmes, Adam Neumann, Do Kwon — sold visions so compelling that investors, employees, and media suspended critical thinking. The bigger the narrative, the harder the fall.
By Industry
By Decade Failed
2020s already dominate — and the decade is barely half done.

Frequently Asked Questions
What is the biggest startup failure of all time?
By value destroyed in a single event, Terra/Luna leads (~$60B vaporized in 72 hours in May 2022). By peak valuation lost, WeWork ($47B → bankruptcy) and FTX ($32B → bankruptcy) follow. By total raised and lost, WeWork ($11.5B) and Byju's ($5.5B) top the list. 23andMe joined the list in March 2025 after Chapter 11.
How much money has been lost in startup failures?
The 30 biggest startup failures alone destroyed over $690B in valuation. Across the broader graveyard, VC-funded startups have written off an estimated $1 trillion+ in the post-ZIRP era (2022–2026) alone.
What was the largest single-event startup collapse?
Terra/Luna in May 2022 — about $60B in market cap erased in 72 hours when the UST algorithmic stablecoin broke its $1 peg and the sister token LUNA hyperinflated. The contagion took down Three Arrows Capital, Celsius, Voyager Digital, and BlockFi for tens of billions more.
What do the biggest startup failures have in common?
Four patterns: (1) massive overfunding that masked broken economics; (2) governance failures — weak boards, no CFO, related-party transactions; (3) charismatic founders who prioritized story over math; (4) a market regime that rewarded growth over profit, until it didn't.
Are AI startups starting to fail at scale?
Yes — the first wave hit in 2024–2025. Inflection AI was absorbed by Microsoft, Character.AI by Google, Stability AI underwent forced restructuring, and Olive AI (~$856M raised) shut down. Many "GPT wrapper" startups are running out of differentiation as foundation models commoditize core capabilities.
Are startup failures increasing in 2025-2026?
Yes. SimpleClosure reports startup shutdowns up 25%+ year-over-year in 2024, with later-stage failures accelerating as 2021-vintage cohorts run out of runway. The 2025 cohort added 23andMe (Mar 2025), SmileDirectClub (Dec 2023 shutdown carried into 2024), and a wave of first-gen AI shutdowns.
