TL;DRMore than 220 former unicorns have lost their billion-dollar valuations as the AI boom redirects venture capital toward a handful of companies. PitchBook data shows startups that last raised in 2021 are worth 68% less on average, with SaaS firms the largest casualty class.
The AI boom has created a two-speed startup economy. Companies building on generative AI are raising at historically unprecedented valuations, while startups that last raised capital before ChatGPT launched in November 2022 are watching their worth collapse. According to PitchBook valuation estimates, more than 220 companies that once held billion-dollar valuations have now fallen below that threshold, a cohort that includes consumer brands like Glossier, Savage X Fenty, AG1, and The Farmer’s Dog.
The numbers are stark. Startups that last raised in 2021 are worth 68% less on average. Those that last raised in 2022 have seen a 52% decline. The sharpest pain is concentrated in enterprise software: 75 SaaS companies appear on PitchBook’s fallen unicorn list, double the number of fintech firms, the next-largest category. Scheduling startup Calendly is among the most prominent names.
Where the money went
The capital did not disappear. It moved. In the first quarter of 2026 alone, AI startups raised $255.5 billion globally, surpassing the full-year 2025 total for AI venture funding. But the distribution was extreme: three deals, OpenAI’s $122 billion round, Anthropic’s $30.6 billion raise, and xAI’s acquisition by SpaceX, accounted for 67% of that capital. Venture firms that backed the winners early are seeing returns that justify ever-larger concentrated bets on AI.
