Palantir is only the 15th most overvalued:

P/E isn't the only way to value a company. A company can be unprofitable, and therefore not have a P/E, and still be worth something. A quickly growing startup that is losing money on paper but has free positive cash flow is one example.

		Well, Palantir is the only really large company in the P/E top section. You could argue smaller companies have more upside and could thus justify their valuation easier
