The Crunchbase Unicorn Board reached a new milestone in August, cresting above $6 trillion in total value for the first time.

Still, only four companies joined the unicorn board last month — the lowest count so far this year, mirroring the slower pace of venture funding in August.

August’s newly minted unicorns

Here are last month’s four new unicorns, by sector.

Value jumped in 2025

Year to date through August, the value of the board has increased by close to $600 billion — including valuation additions from existing and new unicorns on the board — a significant increase from 2024 and 2023.

Of that, $154 billion was added by 91 newcomer companies who joined in the first eight months of the year.

The most highly valued new unicorns this year so far are AI lab Thinking Machines Lab at $12 billion, healthcare clinical notetaker Abridge at $5.3 billion, and 27-year-old AI data storage company DataDirect Networks at $5 billion.

But by far the largest new value added to the board this year so far was by companies that initially joined in prior years. The largest valuation increases through August went to OpenAI, SpaceX, Anthropic, Safe Superintelligence and Anduril.

And while August saw a slowdown in unicorn creation, two large raises by unicorns Anthropic and Databricks in the first few weeks of September have already pushed the Unicorn Board’s total valuation further this month, to $6.2 trillion as of this writing.

Methodology

The Crunchbase Unicorn Board is a curated list that includes private unicorn companies with post-money valuations of $1 billion or more and is based on Crunchbase data. New companies are added to the Unicorn Board as they reach the $1 billion valuation mark as part of a funding round.

The unicorn board does not reflect internal company valuations — such as those set via a 409a process for employee stock options — as these differ from, and are more likely to be lower than, a priced funding round. We also do not adjust valuations based on investor writedowns, which change quarterly, as different investors will not value the same company consistently within the same quarter.

Funding to unicorn companies includes all private financings to companies that are tagged as unicorns, as well as those that have since graduated to The Exited Unicorn Board.

Exits analyzed here only include the first time a company exits.

Please note that all funding values are given in U.S. dollars unless otherwise noted. Crunchbase converts foreign currencies to U.S. dollars at the prevailing spot rate from the date funding rounds, acquisitions, IPOs and other financial events are reported. Even if those events were added to Crunchbase long after the event was announced, foreign currency transactions are converted at the historic spot price.
