Valuing a VC backed company like Vercel really is a bit of a crap shoot. Even major, publicly held companies aren't valued based on things like annual revenue, profits, or anything that shows up on a P&L.

Vercel is worth exactly what the last person paid for it. There's no real way to come up with another valuation until there's another liquidity event.

Another way to look at it, the last round of investors are valuing in-predictions for future value and have access to potentially private information and financials. From the outside it's not really possible to come up with a valuation to compare to there's, we'd be working with a totally different set of data.
