What I find the strangest is Palantir's market cap and long term valuation show that this is not just retail at the margins - it's significant amounts of money buying up the stock despite its sky high valuation. I don't know if it can be sufficiently explained by "individual actors investing ideologically" or not. Just another day of the stock market being irrational though, I guess!
