In every startup cycle, a few fortunate founders find themselves inundated with term sheets at rapidly growing valuations.

This phenomenon has been on the rise over the past couple years, driven by voracious investor appetite for AI early movers. Since 2024, an estimated 207 AI-focused companies have joined The ½ûÂþÌìÌà Unicorn Board. That’s roughly half of all companies that first hit valuations of $1 billion or more during this period.

Of those, more than a third first secured 10-figure valuations at seed or early stage. That includes some of the most well-known newish unicorns in sectors like foundational AI, robotics and vertical AI.

Many newish unicorns are worth a lot more than $1 billion

While a $1 billion valuation is the threshold for claiming unicorn status, many newer entrants to the group are now worth much more than that.

Per ½ûÂþÌìÌà data, at least 45 companies that became unicorns in the past 28 months are now valued at $5 billion or more. That’s just over 10% of the total cohort.

So who’s at the top? To answer that question, we put together a sample list of 18 high-profile, newish unicorns with a most recent post-money valuation of $5 billion or more.

Notably, many of these are very young companies. U.K.-based AI infrastructure startup , for instance, launched from stealth just a year ago as a spin-out of crypto mining firm . It recently secured a $14.6 billion post-money valuation.

, a developer of AI-enabled software to control robots, has also scaled up quickly since its inception in 2024. This year, the San Francisco company is reportedly to raise fresh funding at a valuation exceeding $11 billion.

Foundational AI startup , meanwhile, has raised around $3 billion in less than two years since its founding. A round last spring set a $32 billion valuation for the Palo Alto, California-based company.

Newer unicorns are also fundraising at a fast clip

In addition to their youth and ultra-high valuations, many newer unicorns also stand out for the speed and magnitude of their fundraising.

San Francisco-based AI legal tech platform , for instance, has gone from Series A to Series G in about three years and raised close to $1.2 billion along the way.

Predictions marketplaces and are remarkably fast fundraisers as well. New York’s Kalshi has gone from Series C to Series E in the past year, pulling in over $2.4 billion. And Polymarket, another New York-based company  has scooped up close to $2.9 billion in the past two years.

Foundational AI is also scaling superfast. Medical AI company went from Series A to Series D in less than a year, with the Cambridge, Massachusetts-based company picking up over $700 million from early 2025 to early 2026. , the developer of AI coding tool Cursor, went from Series A to Series D in under a year, securing over $3.2 billion in that time frame. The San Francisco-based company most recently entered an agreement with , giving the latter Cursor for $60 billion.

Move fast and build things

These are of course remarkable times for mega fundraising rounds, particularly around AI. Cynics might question valuations and check sizes, while optimists might quickly point out that we are in the early days of building foundational technologies of the modern era.

I suppose both have a point. For now, we’re less inclined to pick winners and more engaged in simply keeping score. One thing is clear: It’s a very well-capitalized playing field.
