Alexander Caedmon Karp (born October 2, 1967) is an American businessman who is the co-founder and chief executive officer of Palantir Technologies, a software company that builds big-data and artificial-intelligence platforms for defense, intelligence, and commercial customers. Trained as a lawyer and a social theorist rather than as an engineer, Karp helped start Palantir in 2003 with the investor Peter Thiel and three others, and he has run the company as CEO ever since. Under his leadership Palantir grew from a small contractor for U.S. intelligence agencies into one of the most valuable and most debated firms in the AI industry, a transition that accelerated after its 2020 stock-market debut. Karp is also known for an unusual public persona, for outspoken commentary on technology and Western politics, and for the 2025 book "The Technological Republic," which he co-wrote with the Palantir executive Nicholas W. Zamiska.[1][3]

Karp was born in New York City on October 2, 1967, and grew up in Philadelphia. His father, Robert Joseph Karp, was a clinical pediatrician, and his mother, Leah Jaynes Karp, was an artist; he has described a childhood shaped by his parents' political activism, art, and progressive politics. He has said that his upbringing combined Jewish and African American family traditions.[1]
He attended Haverford College, a liberal-arts school outside Philadelphia, graduating in 1989 with a bachelor's degree in philosophy. He then enrolled at Stanford Law School, where he earned a Juris Doctor in 1992 and first met Peter Thiel, a fellow law student who would later recruit him to run Palantir. Rather than practice law, Karp moved to Germany to pursue graduate study in social theory and philosophy. He completed a doctorate at the Johann Wolfgang Goethe University in Frankfurt in 2002, working in the milieu of the Frankfurt School associated with Jurgen Habermas and Theodor Adorno; his dissertation examined aggression, jargon, and culture in everyday social life. Karp is a fluent German speaker, an experience he has credited with shaping both his intellectual outlook and his later management style.[1]
After completing his PhD, Karp founded a money-management firm called the Caedmon Group, based partly in London. Using a small inheritance from his grandfather as seed capital, he attracted a circle of wealthy, largely European investors. The firm gave him both investing experience and a network of backers that he would later draw on when Palantir needed early funding.[1]
Palantir Technologies was founded in 2003, with the company sometimes dating its operational beginnings to 2004. Its co-founders were Peter Thiel, who became chairman; Karp, who became chief executive officer despite having no engineering background; and three technologists, Joe Lonsdale, Stephen Cohen, and Nathan Gettings. Thiel had conceived the idea of adapting the fraud-detection techniques used at PayPal, which he had co-founded, into software that could help analysts find patterns across large, messy data sets. He named the new company after the "palantiri," the seeing-stones in J. R. R. Tolkien's fiction. Thiel chose Karp, his former Stanford Law classmate, to lead the company in part because Karp was an outsider to Silicon Valley engineering culture.[1][2]
In its early years Palantir worked closely with the U.S. national-security community. The CIA's venture-capital arm, In-Q-Tel, invested roughly two million dollars and became an early customer, and the company built its first products to help intelligence and defense agencies integrate and analyze data. This focus on government and defense AI work, including contracts with military, intelligence, and law-enforcement agencies, defined Palantir for much of its first decade and drew sustained criticism from privacy and civil-liberties advocates.[1][2]
Palantir's business is organized around a handful of core software platforms, which Karp has positioned as an "operating system" for large institutions:
| Platform | Purpose |
|---|---|
| Gotham | Data-integration and analysis platform used by militaries, intelligence agencies, and counter-terrorism analysts |
| Foundry | Platform for commercial and civil-government customers to connect, model, and operate on their data |
| Apollo | Continuous-delivery system that deploys and updates Palantir software across cloud, on-premises, and classified environments |
| AIP | Artificial Intelligence Platform, launched in April 2023, that brings large language models into private and secure networks |
The 2023 launch of the Artificial Intelligence Platform, or AIP, proved especially important to the company's later growth. AIP let customers connect commercial large language models to their own proprietary data and operations under tight governance, and Karp credited it with driving a surge of demand from U.S. businesses during the generative-AI boom that followed the release of systems such as ChatGPT.[2]
On September 30, 2020, Palantir went public through a direct listing on the New York Stock Exchange under the ticker symbol PLTR, rather than a traditional initial public offering. Around the listing Karp received an equity-heavy compensation package, including stock options and awards, that was valued at roughly 1.1 billion dollars, making him by some measures the highest-paid chief executive of a U.S. public company that year.[4] The company moved its headquarters from Palo Alto, California, to Denver, Colorado, in 2020, and later shifted its stock listing to the Nasdaq in November 2024.[1][2]
Palantir's revenue and profile expanded sharply in the mid-2020s. Annual revenue reached about 2.87 billion dollars in 2024, up roughly 29 percent year over year, and approximately 4.4 billion dollars in 2025.[6][7] The momentum continued into 2026: in results reported on May 4, 2026, the company said first-quarter revenue rose about 85 percent from a year earlier to 1.63 billion dollars, led by booming U.S. commercial and government demand, and it raised its full-year guidance to around 7.7 billion dollars.[8] Roughly half of Palantir's revenue comes from government customers and half from commercial clients. The company was added to the S&P 500 in September 2024, and at points in 2025 its market capitalization exceeded 400 billion dollars, a valuation that prominent commentators argued was extreme relative to its sales.[2]
Karp is an unconventional chief executive who cultivates an eccentric public image. He has never learned to drive, owns several homes chosen for their proximity to cross-country ski trails, and is an avid skier who has said he trains for hours each week; profiles have also noted his interest in tai chi, qigong, and meditation. He avoids social media, keeps a deliberately small personal footprint, and often appears in interviews wearing athletic gear. These habits have become part of his persona as a counterpoint to the conventional technology executive.[10]
Politically, Karp describes himself as a progressive who has supported Democratic candidates, and he has at times called himself a socialist, while sharply criticizing what he sees as the political timidity and anti-military attitudes of much of Silicon Valley. He is a vocal advocate for closer cooperation between technology companies and Western governments, particularly the United States and its allies, and a strong supporter of Israel and of robust national defense. In June 2022 he traveled to Kyiv to meet Ukrainian president Volodymyr Zelensky, and Palantir's software was subsequently used to support Ukraine's war effort. Karp has frequently defended Palantir's defense and intelligence work against critics, arguing that building powerful software for Western states is both a business opportunity and a moral and strategic necessity.[1][2]
These arguments form the core of "The Technological Republic: Hard Power, Soft Belief, and the Future of the West," the book Karp published on February 18, 2025, with Nicholas W. Zamiska, a senior Palantir executive who leads the company's corporate-affairs and legal functions. The book argues that Silicon Valley has drifted from the national purpose that once tied early computing to government and defense, and it calls for a renewed partnership between the software industry and the state to harness artificial intelligence in defense of liberal democracies. It became a number-one New York Times bestseller.[3]
Karp's rising profile has been accompanied by both acclaim and controversy. Time magazine named him to its 2025 list of the 100 most influential people in the world, describing him as the embodiment of a new kind of Silicon Valley leader who openly embraces defense work.[9] He has repeatedly ranked among the highest-paid executives of U.S. public companies, and the appreciation of his Palantir holdings has made him a multibillionaire. Bloomberg's Billionaires Index has tracked his fortune at well over ten billion dollars, with estimates exceeding eighteen billion dollars during 2025; the figure swings sharply with Palantir's volatile share price.[5][11] At the same time, Palantir's deep involvement in surveillance, defense, and immigration-enforcement contracts has made both the company and Karp recurring targets of criticism from civil-liberties groups, which he has consistently and publicly rebutted.[1][2]
