The dot-com bubble lasted roughly five years on the way up and about two and a half years on the way down. The Nasdaq Composite began its dramatic climb around 1995, hit its all-time peak of 5,048.62 on March 10, 2000, then crashed to a low of 1,139.90 by October 4, 2002. From peak to trough, the collapse took 31 months and wiped out about 78% of the index’s value.
How you measure the bubble’s duration depends on which phase you’re asking about: the buildup, the crash, or the full recovery. Each tells a different story.
The Buildup: 1995 to 2000
The speculative run-up in internet stocks began in the mid-1990s as the commercialization of the web drew massive investor enthusiasm. Between 1995 and 2000, the Nasdaq Composite increased fivefold. The most intense period of speculation was shorter, roughly 1998 to early 2000, when companies with no profits and sometimes no revenue were going public at sky-high valuations. Investors poured money into anything with a “.com” in the name, betting that the internet would make traditional business fundamentals irrelevant.
Low interest rates, easy access to venture capital, and a wave of retail investors entering the market all fed the frenzy. IPOs routinely doubled or tripled on their first day of trading. Media coverage amplified the excitement, and fear of missing out kept new money flowing in even as valuations became harder and harder to justify.
The Crash: March 2000 to October 2002
The peak came on March 10, 2000, when the Nasdaq closed at 5,048.62. What followed was not a single dramatic day but a grinding, extended decline. The sell-off accelerated as investors realized that most internet companies were burning through cash with no clear path to profitability. Venture capital dried up, ad spending dropped, and companies that had been valued in the billions ran out of money.
By October 4, 2002, the Nasdaq had fallen to 1,139.90, a decline of 76.81% from its peak. Hundreds of dot-com startups went bankrupt. Companies like Pets.com, Webvan, and eToys, once Wall Street darlings, simply ceased to exist. Even established tech firms saw their stock prices fall by 80% or more. Trillions of dollars in market value evaporated over those 31 months.
The Recovery: Over a Decade
The aftermath lasted far longer than the crash itself. The Nasdaq began a slow recovery after bottoming out in late 2002, but it didn’t get far before the financial crisis of 2007 to 2009 knocked markets down again. The Nasdaq didn’t fully reclaim its March 2000 peak until May 2013, more than 12 years after the bubble burst.
That timeline matters for anyone thinking about market recoveries. An investor who bought at the peak in 2000 and held on would have waited over a decade just to break even, not accounting for inflation. Adjusted for inflation, the real recovery took even longer.
What Survived the Bubble
Not every company from the era disappeared. Amazon, which lost more than 90% of its stock value during the crash, survived because it had a real business underneath the hype. eBay, Priceline (now Booking Holdings), and a handful of others weathered the downturn and eventually thrived. The companies that made it through generally had actual revenue, a viable business model, or enough cash reserves to outlast the drought in funding.
The core thesis of the dot-com era, that the internet would transform commerce, communication, and daily life, turned out to be correct. The bubble’s lesson wasn’t that internet companies were worthless. It was that speculative pricing detached from business reality doesn’t hold up, and that the distance between a promising idea and a sustainable company is enormous. The five-year run-up created the illusion that the distance didn’t matter. The 31-month crash proved it did.
