AI is crushing startup valuations for companies that raised before ChatGPT existed

Over 220 former unicorns, including brands like Glossier and Calendly, have lost their billion-dollar valuations as AI-driven capital shifts toward a select few companies, with PitchBook data showing 68% average decline for startups that last raised in 2021. AI startups like OpenAI and Anthropic secured $255.5 billion in Q1 2026 alone, while traditional SaaS firms face existential challenges due to declining growth rates and investor preference for AI-native solutions.
More than 220 companies that once held billion-dollar valuations have fallen below that threshold as the AI boom redirects venture capital toward a small group of firms. PitchBook data reveals startups that last raised in 2021 are now worth 68% less on average, with enterprise software (SaaS) companies hit hardest—75 such firms appear on the fallen unicorn list, including Calendly. The shift is stark: AI startups raised $255.5 billion globally in Q1 2026, with three deals—OpenAI’s $122 billion round, Anthropic’s $30.6 billion raise, and xAI’s acquisition by SpaceX—accounting for 67% of the capital. The concentration of funding extends beyond venture firms, with sovereign wealth funds from Singapore, Saudi Arabia, and Abu Dhabi investing heavily in frontier AI. This has left pre-ChatGPT startups struggling, as investors prioritize AI-native firms with explosive growth over traditional SaaS companies. AI-native enterprise spending surged 94% year-over-year in early 2026, while SaaS growth rates have stagnated, compressing to single digits for most operators. Enterprise software companies face a structural threat from generative AI and vibe coding platforms, which allow non-developers to build custom applications, undermining the value of traditional SaaS products priced at $50–$200 per seat. The market has repriced accordingly, with software stocks briefly trading below the S&P 500’s forward price-to-earnings ratio—a historic anomaly. Private SaaS firms now face an unbridgeable gap between their last marked valuations and what buyers would pay, trapping them in a cycle where down rounds, IPOs, or profitability are nearly impossible without an AI narrative. For many pre-ChatGPT startups, acquisition remains the only viable exit. However, the shrinking pool of buyers—now dominated by AI-focused acquirers—has made even this path difficult. The disparity in valuations and investor priorities has created a two-speed economy, where AI infrastructure firms thrive while legacy startups grapple with survival.
