Having a market cap? You mean a non-zero market cap?
Or do you mean a greater vs. lesser market cap? As compared to what?
If market cap was intrinsic value underlying itself, the business would be irrelevant. That is a circular “origin” of value that even novice investors would want to sell out of. That doesn’t work.
Success that matters for investors isn’t evidenced by a high market cap. But by a market cap not keeping up with business growth. I.e. shares becoming undervalued. By actual/predicted growth increasing faster than cap, or cap falling faster than actual/predicted downturns.
