AI Unicorns Surge 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, according to Crunchbase News. More than a third of these AI-focused unicorns secured 10-figure valuations at the seed or early stage. This trend reflects a broader pattern in startup cycles where founders receive multiple term sheets amid high investor interest in AI.
High Valuations for Young AI Companies
At least 45 companies that became unicorns in the past 28 months are now valued at $5 billion or more, based on Crunchbase data. For example, U.K.-based AI infrastructure startup Nscale launched from stealth a year ago as a spin-out of crypto mining firm Arkon Energy and recently secured a $14.6 billion post-money valuation. Physical Intelligence, a San Francisco developer of AI-enabled software for robots, began in 2024 and is reportedly in talks to raise funding at a valuation exceeding $11 billion. Meanwhile, foundational AI startup Safe Superintelligence, based in Palo Alto, California, has raised around $3 billion in less than two years, with a round last spring setting its valuation at $32 billion.
Rapid Fundraising Among New Unicorns
Many newer unicorns are fundraising at an accelerated pace, such as San Francisco-based AI legal tech platform Harvey, which progressed from Series A to Series G in about three years and raised close to $1.2 billion. New York-based predictions marketplace Kalshi advanced from Series C to Series E in the past year, raising over $2.4 billion, while another New York company, Polymarket, has raised close to $2.9 billion in the past two years. In the foundational AI sector, Cambridge, Massachusetts-based medical AI company OpenEvidence moved 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 it for $60 billion, according to Crunchbase News.
The Current Landscape of AI Fundraising
These developments underscore remarkable times for mega fundraising rounds in AI, with at least 45 companies reaching $5 billion valuations shortly after becoming unicorns. Related Crunchbase queries include examples of companies valued at $5 billion or more that first became unicorns in 2024-2026, as noted in the source material. As a widely-known context, the AI sector has seen increased investor activity in recent years, driven by advancements in technology, though specific outcomes remain uncertain.
