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 traditional IPO exit is being replaced by a perpetual secondary market for elite private companies. This new paradigm provides liquidity for investors and employees without the high costs and regulatory burdens of going public. This shift fundamentally alters the venture capital lifecycle, enabling longer private holding periods.

Top-tier private companies like Stripe and Databricks are actively choosing to delay IPOs, viewing the public market as an inferior "product." With access to cheaper private capital and freedom from quarterly scrutiny and activist investors, staying private offers a better environment to build long-term value.

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.

For high-growth companies, reaching a $100M ARR milestone no longer automatically triggers IPO plans. With abundant private capital, many founders now see going public as an unnecessary burden, preferring to avoid SEC reporting and gain liquidity through private growth rounds.

The venture capital paradigm has inverted. Historically, private companies traded at an "illiquidity discount" to their public counterparts. Now, for elite companies, there is an "access premium" where investors pay more for private shares due to scarcity and hype. This makes staying private longer more attractive.

A strong power law effect is at play across markets. In the private sphere, the top 10 unicorns now account for almost 40% of all unicorn value, doubling their share since 2020. This concentration mirrors the public markets, highlighting an increasing 'winner-take-all' dynamic.

The trend of companies staying private longer and raising huge late-stage rounds isn't just about VC exuberance. It's a direct consequence of a series of regulations (like Sarbanes-Oxley) that made going public extremely costly and onerous. As a result, the private capital markets evolved to fill the gap, fundamentally changing venture capital.
