Since the rise of artificial intelligence, particularly with the popularity of ChatGPT in late 2022, Palantir CEO Alex Karp has sold a considerable amount of his company’s stock.
Palantir Technologies (PLTR +5.15%) has been a major player in the AI market, seeing its stock price skyrocket by 1,620% during this time.
While the stock has been climbing, Karp has voiced his concerns about short sellers, labeling their actions as “market manipulation” after hedge fund manager Michael Varley revealed a significant short position against the company in the third quarter of 2025.
However, it’s noteworthy that Karp himself has liquidated $2.2 billion in Palantir stock over the past three years. After his latest sale in November 2025, he retains around 6.4 million Class A shares, valued at approximately $832 million, which might hint to investors that they should be cautious.
Here are some key points to consider.
Palantir is leading in the artificial intelligence landscape
Palantir specializes in helping clients navigate complex data. Their primary software offerings, Gotham and Foundry, structure information into a framework that utilizes machine learning to improve decision-making. As more data is processed, these systems can better recommend actions.
This specialist software architecture sets Palantir apart from other analytical tools. Additionally, they are working on an adjacent artificial intelligence platform that enables developers to integrate large-scale language models into their applications, streamlining data utilization and process automation through natural language.
Last year, Forrester Research identified Palantir as a leader in AI decision-making tools. Recently, Morgan Stanley analyst Sanjit Singh noted that Palantir is becoming a benchmark for enterprise AI, suggesting promising sales growth in the coming years. Grand View Research anticipates a 38% annual increase in spending on AI platforms through 2033.
Palantir has shown strong financial performance
Palantir recently reported fourth-quarter results that exceeded expectations, with a 34% increase in customer count, now totaling 954. The average spending per existing customer rose 139%, leading to a net revenue retention increase for the ninth straight quarter. Consequently, revenue soared by 70%, reaching $1.4 billion, marking a consistent acceleration over the past decade.
The non-GAAP operating margin climbed 7 percentage points to 57%, yielding an extraordinary Rule of 40 score of 127%, a rarity for software companies. Furthermore, non-GAAP net income surged by 79% to $0.25 per diluted share.
Looking forward, management is aiming for a 60% revenue growth target for the full year of 2026, a slight uptick from the 56% growth forecast for 2025.
Palantir’s stock is markedly expensive
Despite a 37% decline from its peak due to concerns about the impact of AI code generation tools on the software industry, Palantir shares are still trading at an astonishing multiple of 74 times. This makes it the most expensive stock globally, considerably outperforming other companies; for example, App Labin sits at 30x sales. This means Palantir could see a significant drop and still hold its position as the priciest stock in the index.
I can’t quite pin down the reasons behind Alex Karp’s decision to sell $2.2 billion in stock over the past three years. There are many benign reasons insiders might sell. Still, I think it’s wise for investors with significant stakes in Palantir to heed Karp’s actions. While Palantir’s financials are robust, the stock’s valuation is steep, leading to a risk-reward scenario that leans heavily towards risk. Perhaps now is a fitting moment for some investors to take profits.
