The rally was driven by a particularly strong quarterly earnings report that showed both that the company’s growth remains impressive but also that the firm’s management has grown critical of frontier artificial intelligence ( AI ) labs. According to CEO Alex Karp, some of the most prominent AI entities are attempting to ‘drug addict us to a future they believe they control,’ and the executive urged a trajectory in which companies own their models and use Palantir as their top layer. Lastly, despite the ‘otherworldly’ quarter and strong August stock market performance, some analysts believe that PLTR stock’s rally is close to ending. As Finbold reported on August 25, technical analysis ( TA ) indicates there is a possibility Palantir’s share price might crash toward $107 by the end of 2026. Featured image via Shutterstock
