The startup, founded by 29-year-old billionaire Alexandr Wang, is also reportedly working on the Defense Innovation Unit's program to integrate AI into military planning and operations along with Anduril and Microsoft, as well as on President Donald Trump's proposed missile defense shield Golden Dome.In May, the Pentagon announced agreements with OpenAI, Alphabet, Nvidia, SpaceX, Microsoft, Amazon and Reflection for expanded use of advanced AI tools in military operations. Meta took a 49% stake in Scale AI last year and brought on Wang as the chief AI officer. Key BackgroundThe Scale AI deal is the latest in Defense Secretary Pete Hegseth's push to fast-track AI adoption across the department. In a January strategy memo, Hegseth laid out plans to expand the use of AI tools and strip away what he described as bureaucratic barriers slowing the adoption of new technology. Scale AI, founded in 2016, built its business on data labeling—paying contract workers to label images and text used to train AI models—for customers including OpenAI, Google, Microsoft and Meta, before pivoting more aggressively into defense work. Meta's $14.3 billion investment last year for a 49% stake brought Wang into Meta's superintelligence efforts and gave the social media giant significant exposure to the federal AI contracting boom.Big Number$29 billion. That’s Scale AI’s valuation after raising $14.3 billion from Meta last June. Forbes estimates Wang, who in 2022 held the title of world’s youngest self-made billionaire, is now worth $3.2 billion. Scale AI cofounder Lucy Guo, who left the company in 2018, took the title of world’s youngest self-made woman billionaire last April, unseating Taylor Swift, thanks to her 3% stake in the startup. Kalshi cofounder Luana Lopes Lara took the title in December 2025.Crucial Quote“As the era of small-scale AI pilots gives way to enterprise-wide deployment, the infrastructure decisions the Department makes known – which platforms to trust, which data operations to invest in, which partners to build for the long term – will shape the operational AI capabilities of the U.S. military for the decade ahead,” said Kathryn Harris, head of defense at Scale AI, in Wednesday’s press release.
