As the stock continues its relentless climb, it has made Chief Technology Officer Shyam Sankar a billionaire, joining four Palantir co-founders whose stakes have also grown to 10 figures or more.The data analytics company’s shares hit an all-time high of $160.66 on Monday, lifting Sankar’s net worth to $1.3 billion, according to the Bloomberg Billionaires Index. The firm reported a 48% increase in second-quarter revenue after the market close, saying artificial intelligence was having an “astonishing impact” on its business..A spokesperson for Denver-based Palantir didn’t respond to a request for comment on Sankar’s net worth. Sankar, 43, is the first non-founding Palantir employee to reach billionaire status, although his fortune is dwarfed by those of Chief Executive Officer Alex Karp ($14.3 billion) and President Stephen Cohen ($5.8 billion), according to Bloomberg’s wealth index. Peter Thiel, who serves as chairman, has a $23.8 billion net worth, although only about 60% of that is in Palantir equity. Venture capitalist Joe Lonsdale, another co-founder who left the company in 2009, still owns about $1.3 billion of Palantir shares, according to the index.After hovering below $40 per share following its 2020 direct listing, Palantir’s stock price exploded after President Donald Trump’s win last November, more than doubling through mid-February as it announced a flurry of new government contracts. On Thursday, the Army said it would be pooling 75 existing contracts with Palantir into a single agreement worth up to $10 billion over the next decade.Retail traders have continued to pile in: Palantir has the third-highest volume of net retail purchases for any stock, behind only Tesla Inc. and Nvidia Corp., according to June data from Vanda Research. The stock is up 567% in the past 12 months, making it by far the best-performing member of the S&P 500 in percentage terms.Early EmployeeWhile still relatively rare, the ranks of non-founding executives who’ve achieved billion-dollar fortunes are growing, due to a burst of interest in artificial intelligence- and tech-related stocks. Alphabet Inc. CEO Sundar Pichai now has a $1.1 billion fortune as investors have pushed the company’s stock back toward an all-time high. Nvidia, the first company to hit a $4 trillion market capitalisation, counts six billionaires among its ranks, including three board members and two executives. .Read more:.Boardroom Talk: Meet Peter Thiel, ten-bagger Palantir's chairman, investing maven, tech genius.Sankar joined Palantir a few years after its 2003 founding as its 13th employee and chief operating officer. It was still a stealthy startup at the time, but Sankar later said his decision to join was based on his belief in America from his own childhood. “My parents’ journey showed me that America is not a place where everything is perfect, but it is a place where anything is possible,” he wrote in a 2012 post. Sankar’s dad was born in a mud hut in Tamil Nadu in southern India and was the first person in his family to attend college, studying pharmacy. Shyam was born in Mumbai, but lived in Lagos, Nigeria, as an infant. The family relocated to Orlando when he was two, where they initially ran a successful souvenir business for theme parks, and later a dry-cleaning business that went bankrupt, Sankar wrote. After graduating with engineering degrees from Cornell University and Stanford University, Sankar turned down a job offer at a consulting company to join a startup — Xoom Corp. — at the encouragement of his father. “My father urged me to take the risk and fight the machine and gave his blessing,” he recounted. After two years at Xoom, Sankar signed on as Palantir’s first business hire.At Palantir, Sankar helped develop the forward deployed engineer model, which emphasises sending engineers to work with customers onsite and has become a company hallmark.‘Leaner, Smarter’Sankar’s public profile has risen along with the company’s stock since being named CTO in January 2023. He’s emerged as a prominent advocate for revitalizing investment in the defence industry, authoring a 2024 treatise that argued in favour of breaking up the dominance of big legacy military contractors.In June, Sankar announced he was one of four tech executives joining the US Army Reserve’s newly formed Executive Innovation Corps, according to an Army press release. The unit was established to recruit private-sector experts to serve part-time as advisers, working on initiatives including one to “make the force leaner, smarter, and more lethal,” according to the release.About two-thirds of Sankar’s Palantir stake is in the form of Class B shares, which have 10 times the voting rights of its publicly traded common stock. Sankar doesn’t hold any of the company’s super-voting Class F shares, however, which guarantee that three of its co-founders — Karp, Thiel and Cohen — maintain nearly 50% of the voting power, regardless of the number of shares they sell. The three-class voting structure has come under criticism from investors as Palantir has taken an increasingly important role in managing data for the federal government. After selling off modest quantities of his Palantir stake following the company’s direct listing in September 2020, Sankar ramped up his sales in 2024, unloading almost $370 million worth on Dec. 3, by far his largest transaction to date. Sankar’s sales were part of a blitz of insider selling that saw Palantir’s founders and upper management cash out more than $4 billion last year. Sankar also holds 1.5 million stock options — at an exercise price of $11.38 — that are scheduled to vest quarterly through May of next year. If he was able to exercise them today, they’d be worth more than $224 million, according to Bloomberg’s wealth index..© 2025 Bloomberg L.P.
