A fundamental shift has occurred where massive value is created and held in private markets. The top six private tech companies (Anthropic, OpenAI, etc.) have a combined valuation of $2.4 trillion, surpassing the $1.7 trillion total market cap of all IPOs over the past decade.

SpaceX, Anthropic, and OpenAI are now worth more than every US tech company that has gone public in the last 45 years. This signals a massive shift where wealth creation is happening in private markets, locking out the average investor.
A decade ago, 88% of a tech company's value was created post-IPO. For recent IPOs, 55% of the market cap creation happened while the company was still private, fundamentally changing where investors capture growth.
Unlike a decade ago, today's most transformative, high-growth companies like OpenAI and Anthropic are choosing to remain private for longer. This trend concentrates the highest potential returns in private markets, making it difficult for public investors to 'own the future' of technology.
The venue for tech value creation has dramatically shifted from public to private markets. For recent IPOs, over half of their market cap was generated while private, a stark reversal from ten years prior when 88% of value was created post-IPO.
Venture-backed private companies represent a massive, $5 trillion market cap, exceeding half the value of the 'Magnificent Seven' public tech stocks. This scale signifies that private markets are now a mature, institutional asset class, not a small corner of finance.

With billions in private capital available, companies no longer need to IPO for growth financing, staying private for over a decade. This fundamentally shifts value creation and innovation away from public markets, unlike in the 1990s when firms like Amazon went public to raise small sums.
An a16z partner highlights a major disconnect where fewer than five public software companies are growing over 30%, while private AI giants like OpenAI and Anthropic are adding massive revenue, shifting the growth focus to private ventures.
The private tech market has grown 10x in 10 years to a staggering $5 trillion valuation. This is nearly a quarter of the S&P 500's market cap, highlighting a massive shift of economic power away from public exchanges.
The venture capital landscape is experiencing extreme concentration, with a handful of AI labs like OpenAI and Anthropic raising sums that rival half of the entire annual VC deployment. This capital sink into a few mega-private companies is a new phenomenon, unlike previous tech booms.
Unlike previous tech eras, today's top AI companies (e.g., OpenAI, SpaceX) are achieving valuations in the hundreds of billions to over a trillion dollars while still private. This unprecedented scale places them among the world's largest companies before they even enter public markets.
