Palantir (NASDAQ: PLTR) shareholders have had a rough past year. Since setting a new all-time high last October, the stock has marched straight down and is off around 35% from that high. This weakness comes despite reporting incredible results, including an 85% growth rate last quarter
Palantir is blowing past all expectations and looks unstoppable from a business standpoint. But is it a safe stock to buy in the second half of 2026?

I don’t think so, and it’s not because of anything the business is doing, either; it’s a rock-star business. It has to do with one factor: the difference between a great stock and a terrible one
Palantir’s valuation is still out of control despite its sell-off
Even the best companies bought at the wrong price can turn out to be terrible investments. I think that perfectly sums up a Palantir investment right now, as it’s just too highly priced to make any money from it
As a business, Palantir is crushing it, and the company has signed several major clients to use its artificial intelligence (AI)-powered data analytics software to drive efficiencies in businesses and automate workflows. This has led to strong growth, and with 80% growth expected next quarter (Wall Street analysts have historically underprojected Palantir’s actual growth rate), it’s still doing just fine
The issue here isn’t the business; it’s the stock. Over the past few years, Palantir’s stock has run up to unreasonable valuations, and it now trades at around 90 times forward earnings
While some may point out that it’s cheaper than it was, it’s still nowhere near other AI firms growing at similar rates and valued at 20 to 30 times forward earnings. The problem is what this valuation conveys
Let’s say Palantir deserves to trade at a long-term forward earnings multiple of 30. That means Palantir must triple its revenue after2026’s growth has already occurred. Next year, Wall Street analysts project 45% revenue growth. If that growth rate translates directly to an earnings growth rate, it will take three years for Palantir’s earnings to triple
So, it’s safe to say that Palantir has all the growth through 2029 priced into the stock already. There’s a lot that can happen between now and then, and other stocks could deliver incredibly strong returns during the same time frame, making the opportunity cost of investment in Palantir far too high. As a result, I think investors should look elsewhere for AI stocks, as Palantir may be a solid business, but its stock is just too expensive right now
