Public companies are strange creatures. You'd expect a company's valuation to be proportionally tied to its revenue and profit, but it rarely is and Tesla is an extreme case of this.
No, you'd expect it to be tied to the market's assessment of the company's total lifetime value. That will hopefully be informed by revenue and profit, but isn't limited to those, as disruptive companies might be round the corner about to wipe it out, or vice versa.
Which is probably a bit counterintuitive for most people. At least for me it was.
Would the same apply to unicorns? Probably not, because they're special.
