What an awful article. If two stocks were publicly traded, both competing in the same market and one had a market cap 10x the other, it doesn't mean the cheaper one is underpriced. That's akin to saying penny stocks are the sensible place to put your money, they are cheaper. Airbnb may have 10x users, revenue, potential - it may have 100x, or it may have a 10th, this isn't discussed at all. This isn't indirectly profiting from valuable startups, it's backing the weaker company (all things being equal, and assuming those investing in private companies realise they can also invest in public ones), saying the publicly traded companies are underpriced, or that the whole market is high growth and no one horse will win. In other words, standard investment behaviour, not news.
