Former JPMorgan strategist Marko Kolanovic is questioning Palantir ‘s booming valuation. “So if i read this correctly $PLTR now grows slower than an average tech stock, but has a multiple that is ~25 *times* higher than an average tech stock,” Kolanovic wrote in a Monday post on X . “I must not be part of that growth cult i guess.” Known for his bearish calls, Kolanovic departed JPMorgan last summer after nearly two decades at the firm. His comments follow Palantir CEO Alex Karp’s enthusiastic letter to shareholders on Monday , which went as far as to assert that the company’s financial performance is exceeding “many of our greatest expectations.” The company’s first-quarter earnings matched Wall Street’s consensus estimates, while revenue came in better than expected. Palantir raised its revenue forecast for the full-year to a range of $3.89 billion to $3.9 billion, and said it expects commercial revenue above $1.18 billion this year. Palantir said it is benefiting from widespread adoption of its artificial intelligence software, but shares were about 12% lower on Tuesday. The stock has so far been an outlier in an otherwise rough period for technology stocks, notching a gain of more than 40% year to date, compared with the Nasdaq Composite’s 8% slump in 2025. Several analysts are calling for sharp declines in Palantir stock , saying its valuation has run too far and its international growth is lagging.
