Despite its outperformance, the Palantir stock is trading well below its all-time high of $125.41, which it hit on Feb. 19.
What's Driving Rally?
Palantir's stellar quarterly results drove the stock above the $100 psychological barrier in early February.
The stock came under selling pressure after it peaked past the $125 level amid concerns about valuation and anxiety stirred by potential Department of Defense (DoD) spending cuts amid the Department of Government Efficiency (DOGE) initiatives.
Palantir pulled back to a low of $74 on March 10 before resuming its uptrend but came under renewed selling pressure amid the tariff-induced market sell-off.
This time, the stock dropped to $66.12 (April 7) but has climbed about 74% since then.
A North Atlantic Treaty Organization (NATO) contract for Palantir's Maven Smart System for AI-enabled battlefield operations on April 4 fueled a nearly 5% rally in the stock.
Subsequently, the company announced that AI startup Anthropic will leverage Palantir's FedStart to make its Claude large-language model (LLM) available to the government sector.
Palantir's FedStart is a software-as-a-service offering that enables companies to run their products within Palantir's Federal Risk and Authorization Management Program (FedRAMP) and Impact Level (IL) accredited environment.
Separately, the Immigration and Customs Enforcement reportedly awarded a $30 million contract for Palantir to deploy its software add-ons to track immigrants overstaying their visas.
The U.S. government accounted for 63% of Palantir's revenue in 2024.
The stock could build additional momentum going into the company's first-quarter report, which is due after the market closes on May 5.
