The Hidden Data Gold Rush: People Sell Faces, Voices, and Lives to Train AI

Across the globe, thousands are monetizing everyday data—videos, ambient audio, even private chats—to train AI via marketplaces like Kled AI, Silencio, and Neon Mobile. Contributors in places like Cape Town, Ranchi, and Chicago earn small sums, often through broad, irrevocable licenses that allow boundless use and derivative works, with pay sometimes in USD but little recourse. While the money can help close gaps for people in economic hardship, experts warn the practice risks privacy harms, deepfakes, identity theft, and a precarious, wage-driven boom that mainly benefits platforms in wealthier countries as AI data needs outpace scraping from the open web.
