AI Startups Rapidly Attaining Unicorn Status Since 2024
Since 2024, an estimated 207 AI-focused companies have joined The Crunchbase Unicorn Board, representing roughly half of all companies that first hit valuations of $1 billion or more during this period. More than a third of these companies secured 10-figure valuations at the seed or early stage, highlighting a trend of ultra-fast growth in AI sectors like foundational AI, robotics, and vertical AI.
High Valuations Among New Unicorns
At least 45 companies that became unicorns in the past 28 months are now valued at $5 billion or more, according to Crunchbase News. For instance, U.K.-based AI infrastructure startup Nscale, which launched from stealth a year ago as a spin-out of crypto mining firm Arkon Energy, recently secured a $14.6 billion post-money valuation. Other examples include Physical Intelligence, a San Francisco company developing AI-enabled software for robots that began in 2024 and is reportedly in talks to raise funding at a valuation exceeding $11 billion, and Safe Superintelligence, a Palo Alto-based foundational AI startup that has raised around $3 billion in less than two years, with a round last spring setting its valuation at $32 billion.
Examples of Rapid Fundraising
Many newer unicorns have demonstrated exceptional fundraising speed and scale. San Francisco-based AI legal tech platform Harvey has advanced from Series A to Series G in about three years, raising close to $1.2 billion in the process. New York-based predictions marketplace Kalshi has moved from Series C to Series E in the past year, pulling in over $2.4 billion, while another New York company, Polymarket, has raised close to $2.9 billion in the past two years. In foundational AI, Cambridge, Massachusetts-based medical AI company OpenEvidence progressed from Series A to Series D in less than a year, securing over $700 million from early 2025 to early 2026, and San Francisco-based Anysphere, developer of AI coding tool Cursor, went from Series A to Series D in under a year, raising over $3.2 billion and entering an agreement with SpaceX for an option to acquire Cursor for $60 billion.
The Context of AI Fundraising Trends
As is widely known, the AI industry has experienced significant investor interest in recent years, contributing to large funding rounds. According to Crunchbase News, this has created a well-capitalized environment for AI startups, with many achieving high valuations quickly.
