SA¹ú¼Ê´«Ã½

The momentum of new unicorn creation picked up in the final months of 2025, with the fourth quarter showing the highest count of newly minted billion–dollar-plus valued companies since Q2 2022.

In December alone, 23 companies joined The SA¹ú¼Ê´«Ã½ Unicorn Board, more than doubling the count from a year ago.

The value of the unicorn board also picked up significantly in the final month of the year, with the highest-ever value accorded to a private company. That was , which vaulted to the top of the list when it was valued at $800 billion in a secondary market transaction, double its valuation from just three months earlier.

And , the seventh-most highly valued private company at $134 billion, was also valued up from its $100 billion valuation months earlier.

New unicorns in December

Of the new unicorns last month, 15 were U.S.-based, two hail from China, and six are based in Europe, including two from the U.K. and one each from Germany, France, Finland and Belgium.

Financial services, aerospace and AI led with the highest count of new companies to join.

It is worth noting that a third of these companies were more than 10 years old, with some seeing a reacceleration in their business driven by AI.

Methodology

The SA¹ú¼Ê´«Ã½ Unicorn Board is a curated list that includes private unicorn companies with post-money valuations of $1 billion or more and is based on SA¹ú¼Ê´«Ã½ data. New companies are 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 .

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. SA¹ú¼Ê´«Ã½ 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 SA¹ú¼Ê´«Ã½ long after the event was announced, foreign currency transactions are converted at the historic spot price.
