Shares of Palantir Technologies, one of the market's most closely watched artificial intelligence software companies, have slipped 35% from their peak, according to Yahoo Finance — a sharp pullback that has investors debating whether the stock is a safe buy for the second half of 2026.
The drop comes even as the company keeps racking up business. According to simplywall.st, Palantir has landed new AI deals and government contract wins, yet the analysis concludes the stock still looks "fully valued" — meaning its price may already reflect that good news, leaving little room for further gains.
That tension is the heart of the story. As The Globe and Mail puts it, Palantir has been on a "wild ride," and it describes the company as a stock "Wall Street can't agree on." Some observers see a proven AI leader with strong demand from governments and corporations; others worry the valuation has run ahead of the underlying business.
For everyday readers, the disagreement captures a broader question hanging over the AI boom. Palantir became a poster child for investor enthusiasm about artificial intelligence, and its stock soared on that optimism. A 35% retreat from the high raises the possibility that expectations got stretched — a pattern that can play out across hot sectors when hype meets the harder math of profits and price.
None of the sources declare a verdict; instead, they frame Palantir as a coin toss between a durable AI winner and an overpriced favorite.
Why it matters: Palantir's swing is a real-time test of how much the market is willing to pay for AI promises, and how quickly that enthusiasm can reverse.
