Paper Unicorn: What Happens to a Startup When Its Valuation Isn't Backed by Money

Having a valuation of $1 billion was considered the main sign of a successful startup. Today, for many companies, this figure has become a problem. More than 220 former unicorns have already lost their billion-dollar status—their real value is significantly lower than what was recorded. And the number continues to grow.

What is a paper unicorn

A unicorn is a private company valued at $1 billion or more. It is important to understand: this is not money in the bank or revenue, but a figure that investors record at the time of a funding round. If $100 million was invested for a 10% stake, the company is said to be “worth” $1 billion. Until there is an IPO or a sale, this value exists only on paper.

A paper unicorn is a startup with a high valuation from the past that cannot be confirmed today. New rounds are not closing, and the company’s real market value is significantly lower than the recorded one.

Why this is happening now

In 2021, interest rates were near zero, capital was cheap, and investors generously valued startups, outpacing actual business performance. Then came ChatGPT.

After November 2022, money began to flow rapidly into AI. In the first quarter of 2026 alone, AI startups raised $255.5 billion—more than in all of 2025. At the same time, 67% of this amount went to three deals: OpenAI’s $122 billion round, Anthropic’s $30.6 billion round, and SpaceX’s acquisition of xAI.

Investors who previously supported a SaaS company growing at 40% per year are now investing the same money in AI startups growing at 200%. For companies that raised funds before ChatGPT, this means one thing: the next round is either impossible or will occur with a down round.

What is happening to the companies

According to PitchBook, startups that last raised investment in 2021 are currently worth 68% less on average. Those that last closed a round in 2022 are worth 52% less. Among the fallen unicorns are Glossier, Savage X Fenty, AG1, The Farmer's Dog, and Calendly.

Companies find themselves in a deadlock from three sides.

A new round means a down round—raising investment at a valuation lower than the previous one. This dilutes the stakes of early investors and employees and deals a reputational blow.

An IPO is closed off: the public market demands a compelling AI story, which most pre-ChatGPT startups lack.

Operational sustainability is at risk: many of them are unprofitable and cannot operate indefinitely without new capital.

Corporate SaaS has been hit the hardest. Generative AI allows building custom applications without developers—directly threatening the business model of SaaS products priced at $50–200 per seat. In PitchBook’s list of fallen unicorns, there are 75 SaaS companies, twice as many as FinTech companies in second place.

What’s next

Selling to a strategic buyer at a price below peak valuation is the most realistic outcome. Pivoting to AI is possible but requires resources that companies with outdated valuations are increasingly lacking.

According to PitchBook, nearly half of American unicorns have not raised new investment for three years or more. When funds reach their liquidation dates, these companies will either have to raise money or sell. A large amount of “paper value” still needs to be revalued.

A $1 billion valuation achieved in 2021 does not protect a company from decline, nor does it mean the next round will occur at the same or higher price. It reflected specific conditions: zero interest rates, excess capital, and the absence of generative AI. All three conditions have disappeared. The market where this valuation was set no longer exists.
