Dot-com bubble (1999-2000)
Capital concentrated in a small number of internet companies at valuations disconnected from revenue. The Nasdaq Composite peaked in March 2000 and gave back most of its gains over the following two and a half years.
Hundreds of internet companies shut down or sold at fractions of their peak valuations.
Investors began pricing early-stage companies on revenue and unit economics rather than user growth alone.
The current split between AI megarounds and smaller early-stage checks is a reminder that concentrated capital and broad capital can be priced on entirely different logic at the same time.
