A unicorn count is a snapshot of a stale valuation

The record

CB Insights' unicorn tracker, as retrieved on 16 September 2026, counts more than 1,300 private companies worldwide valued over $1 billion, with a combined valuation near $7.4 trillion, and defines a unicorn as a private company valued above that threshold. Crunchbase's unicorn board, also a living list, states plainly which valuation it uses: figures set by investors during priced funding rounds, not internal marks. Both lists are continuously updated trackers rather than dated reports, and both attach a valuation and a date to every company on them.

What the sources establish

Crunchbase's own methodology notes are explicit about what its number is not: the board "does not reflect internal company valuations," such as those set through a 409A process for employee stock options, and it is not adjusted for investor writedowns, which the site notes change quarterly and vary by investor. CB Insights lists a date joined for each company, marking when it first crossed the billion-dollar line, which for many companies is years before the valuation figure shown beside it. Crunchbase quantifies how stale those figures can get: as of January 2025, it reported, only about a quarter of listed unicorns had been valued in a funding round since 2023, and roughly a third had last been priced in 2020 or 2021.

Scope and revision

A unicorn count is therefore a count of last-priced-round outcomes, not current values, and neither tracker claims otherwise once its methodology is read. Carta's own cap-table data illustrates the consequence directly: of 616 US companies that reached a billion-dollar valuation on its platform before the end of 2021, Carta reported in February 2025 that 374 had raised no subsequent round, leaving their listed valuation exactly where the 2021 market set it. A company can sit on a unicorn list for years without a new financing event to confirm or revise the number attached to its name.

The decision in front of you

Editorially: a unicorn count is best read as a list of companies that once cleared a threshold, not a live valuation table. Anyone using the count as a market-health indicator should check the last-raised date before treating the aggregate valuation as current.

• When did the listed company last complete a priced round, and how long ago was that?
• Does the tracker's methodology exclude 409A and other non-round valuations?
• Is the count describing today's private market, or a market from several years ago?

Two trackers with different company lists behind them agree on the underlying rule: a unicorn's value is whatever its last round said, held constant until another round says otherwise. That is a defensible way to keep a list consistent. It is not a way to measure what a company is worth today.
