Prediction: Palantir Stock Will Plummet in the Second Half of 2025. The Reason Why Is Obvious.
Palantir stock is once again a top performer across the S&P 500 and Nasdaq-100, but a sharp sell-off could be in store sooner than later.

Data mining specialist Palantir Technologies (NASDAQ: PLTR) picked up right where it left off in 2024. Last year, Palantir stock was the top performer in the S&P 500 index, as well as the third-best stock in the Nasdaq-100. So far in 2025, things haven't changed much for the artificial intelligence (AI) software player -- as shares have rocketed by an eye-popping 74% as of this writing (June 10).
While the momentum doesn't appear to be slowing down at all for Palantir, my prediction is that the stock will plummet during the second half of the year.
Let's explore some of the trends fueling Palantir stock right now, as well as some interesting breadcrumbs that could support my idea that shares are headed for a sell-off.
