A unicorn is a privately held startup with a valuation of $1 billion or more — a term coined by venture capitalist Aileen Lee in 2013. By mid-2026, CB Insights tracks over 1,200 unicorns worldwide, but only a handful reach the mega-valuations featured on this list.

Frequently Asked Questions
What exactly is a 'startup unicorn'? The term was coined by venture capitalist Aileen Lee in 2013 to describe any privately held startup valued at $1 billion or more — a threshold once so rare it was compared to a mythical creature.
How are private valuations determined? Valuations are set during funding rounds when investors buy equity at an agreed price per share. Because shares are not publicly traded, figures are estimates tied to the most recent round and can shift rapidly between fundraises.
Where does this data come from? Figures are drawn from the [CB Insights Global Unicorn Club tracker](https://www.cbinsights.com/research-unicorn-companies) and company-disclosed funding announcements as of mid-2026.
Which unicorns are closest to an IPO? Stripe and Databricks have both signalled IPO readiness publicly; Revolut secured its UK banking licence in 2024, a common precursor to a public listing.
