I’ve been tracking pre-IPO valuations and found some interesting patterns

I’ve been looking at how companies like Stripe, Klarna, and SpaceX are priced in secondary markets before IPO.

One thing I’ve noticed:

\- valuations often peak well before IPO announcements

\- retail access is basically non-existent until very late

I started tracking this more systematically (mostly out of curiosity).

Curious, does anyone here actually try to factor pre-IPO pricing into their public market strategy?

Feels like there’s a signal there, but hard to access.
