Palantir (PLTR) stock has received approval from Wall Street, with Rosenblatt Securities analyst John McPeake raising his price target on the defense AI giant’s stock to $200 from $150. This move comes after Palantir posted a 70% Q4 revenue growth and a 93% increase in U.S. sales. McPeak believes that Palanir's role in the AI ecosystem is evolving rapidly due to rising global demand for powerful software software. He also anticipates a shift in Palantar's role as a mission-critical operating system for modern warfare and intelligence. The analyst's price target is within the middle of other high-profile Wall Street calls on the company, with Citi's $235, UBS' $180, and Deutsche Bank's $200.
