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.

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 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.

The private market ecosystem exhibits extreme value concentration. Just 20 'platform companies' account for 80% of all private enterprise value, and a mere 4 companies are responsible for 65%. This power law reality dictates that being in these few key companies is all that matters for generating top-tier returns.

The enormous capital required for AI development is exhausting private markets. This forces giants like the combined SpaceX/xAI entity, OpenAI, and Anthropic towards IPOs, marking a shift back to public markets for funding as the sole source for sufficient capital.

The current market is unique in that a handful of private AI companies like OpenAI have an outsized, direct impact on the valuations of many public companies. This makes it essential for public market investors to deeply understand private market developments to make informed decisions.

The abundance of private capital means the most successful companies no longer need to go public for growth funding. This disrupts the traditional VC model, where IPOs are a primary exit path, forcing firms to re-evaluate how and when they achieve liquidity for their limited partners, even for their best assets.

The enormous private capital available to AI leaders, shown by Anthropic's $10B and xAI's $20B rounds, reduces the urgency to go public. This nearly unlimited appetite from private markets allows these companies to continue their aggressive growth and infrastructure build-outs without the regulatory scrutiny and quarterly pressures of being a public company.

The market for hyper-growth tech companies now exists almost exclusively in private markets, with only 5% of public software firms growing over 25%. With companies staying private for 14+ years, public markets are now for mature, slower-growing businesses.
