The current IPO wave isn't a mini-boom but a concentrated "gigaboom" led by SpaceX, OpenAI, and Anthropic. New NASDAQ rules will fast-track these mega-caps into major indices, forcing billions in passive funds to automatically buy their shares and sell rivals, triggering a massive, non-discretionary capital shift.

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.

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.

For companies like SpaceX, Nasdaq now allows index inclusion in just 15 days (down from six months) and artificially inflates weight by treating a 5% float as 15%. This creates a massive, predictable, and forced buying event from index funds, which must sell other holdings to accommodate the new stock, distorting the market.

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.

An explosion of billion-dollar valuations has created more unicorns than the pool of strategic buyers can support. This problem is worse for AI startups, whose massive valuations often exceed those of the legacy players they disrupt, making acquisition by their most logical buyers impossible and forcing a reliance on a tight IPO market.

The enormous private valuations of AI giants like OpenAI ($1T) and SpaceX ($1.5T) pose a unique challenge for their eventual IPOs. The problem isn't the valuation itself, but the 'float.' A standard 15% float would require public markets to absorb hundreds of billions of dollars, far exceeding even the largest IPOs in history.

Companies like SpaceX and OpenAI command massive private valuations partly because access to their shares is scarce. An IPO removes this barrier, making the stock universally available. This loss of scarcity value can lead to a valuation decline, a pattern seen in other assets like crypto when they became easily accessible via ETFs.

With multiple giants like OpenAI, Anthropic, and SpaceX eyeing public offerings, there's a real concern that the market cannot absorb them all simultaneously. This creates a bottleneck, forcing companies to carefully time their IPOs to avoid cannibalizing investor demand and potentially devaluing their listings.
