The venture capitalist Aileen Lee coined the term “unicorn” in a 2013 TechCrunch article to describe privately held startups valued at $1 billion or more.¹ At the time, only 39 such companies existed globally. Today, more than 1,600 unicorns collectively have raised ~$1.2 trillion and represent an aggregate valuation of $6.8 trillion. That broad cohort includes not only unicorns, but also decacorns (valued at $10 billion or more) and hectocorns (valued at $100 billion or more).²

Now, a new category called “instacorns”³ has emerged to designate startups that achieve a $1 billion valuation at their first institutional capital raise. Those companies effectively are “born” as unicorns, reaching the milestone at or near inception, rather than growing into it over time.

According to data published by Carta in 2024, the median time between venture rounds is roughly 2–3 years, depending on stage, and companies can require seven to eight years to reach unicorn status. And the likelihood of investing in a company that becomes a unicorn is extremely low, well under 1% of venture-backed startups ever achieving a $1 billion valuation.

Given that context, why are “instacorns” being born? You guessed it…AI. Just three years since the launch of ChatGPT in late 2022, investors are willing to take massive bets on founders who have proven themselves to be top minds in AI, whether on the hardware side, the software side, or some bit of both.

The majority of instacorns have a bench of founders with deep technical credibility, a history of pushing frontier AI forward, and a deep conviction that what they’re building will be transformational and disrupt the current environment. And those companies are beginning to proliferate, just as unicorns appear to be dwindling, as illustrated in the chart below.

Instacorn companies need such high valuations from the outset because of a dynamic that occurs at the intersection of dilution, raise size, and valuation. If the company needs $10 million to be successful and wants at most 20% dilution, it must raise at a $50 million post-money valuation. The average dilution at the seed stage and series A is between 19% and 20%.⁴ This aligns with industry averages over the past few years, where 19 - 20% dilution is the standard.

But today’s new startups need more capital than ever before to be competitive. Where is the capital going? First and foremost, talent, as the average startup payroll expenses have been increasing over the last two years. This is especially prevalent among top AI and Machine Learning Engineers, where compensation in the 90th percentile increased 6.9 - 9.1%, depending on the startup's stage.⁵ In the same timeframe, other industries saw only an average increase of 4%, according to labor and statistics data.⁶ Anecdotal data from our company interviews also suggests that joiners do place commensurate value on the “paper” valuation of the comprehensive compensation package they receive—clearly a competitive advantage for a budding, talent-hungry company.

Second, capital is necessary for compute. Developing, training, and operating Large Language Models (LLMs) requires significant computational resources, making them among the most capital-intensive aspects of AI.

Essentially, we are seeing quite a shift in how venture capital prices risk at the frontier. Instacorns are the market’s way of pulling expected future value forward into day-zero valuations, mainly because of companies’ belief both that AI will compress the time it takes to build category-defining companies and that the ultimate valuations accruing to the winners will eclipse what has come before.

To bring further color to this conversation, let’s look at some of recent examples of confirmed Instacorns, including companies becoming unicorns in less than one year.

Will AI enable these companies to grow into their valuations more quickly, more efficiently, and ultimately at a greater scale than ever before? If they do, they will turn out to have been  prescient. If they do not, they may be the latest expression of venture exuberance in a new technological cycle.

We are reminded that, as recently as 2023, Anthropic raised at ~$4 billion valuation, which might have sounded expensive but has since yielded some of the best venture returns in recent decades—thanks, namely, to explosive growth driven by $47 billion in annualized revenue run rate and a $0.965 trillion valuation. ⁷

Given the extreme talent density and large raises required to train models, to build teams, and to dominate markets at scale, some of the next trillion-dollar companies may well emerge from the Instacorn stable.
