- SpaceX filed a confidential IPO request for $75 billion in stock, valuing the company at $1.75 trillion.
- OpenAI is projected to IPO at a valuation of $840 billion.
- Anthropic could go public with a $330 billion valuation.
- PitchBook reports the top ten unicorns represent nearly 40 % of all venture‑backed firms valued at $1 billion or more.
- Nvidia and its peers in the public‑market “Magnificent Seven” dominate the CRSP US Total Stock Market Index, but the private‑market unicorn index is even more top‑heavy, with its top ten holding almost 40 % of the universe.
- CRSP is relaxing its float‑percentage requirements, potentially fast‑tracking SpaceX and other mega‑IPOs into benchmark indexes.
Why it matters: Retail and corporate investors stand to capture a slice of the $2.9 trillion combined IPO valuations, while venture capitalists may see a smaller share as value concentrates in a few firms; benchmark index providers must adapt to these outsized entrants, reshaping market exposure.
