If you were tasked with building a panopticon, your design might look a lot like the information stores of the U.S. federal government—a collection of large, complex agencies, each making use of enormous volumes of data provided by or collected from citizens.

The federal government is a veritable cosmos of information, made up of constellations of databases: The IRS gathers comprehensive financial and employment information from every taxpayer; the Department of Labor maintains the National Farmworker Jobs Program (NFJP) system, which collects the personal information of many workers; the Department of Homeland Security amasses data about the movements of every person who travels by air commercially or crosses the nation’s borders; the Drug Enforcement Administration tracks license plates scanned on American roads. And that’s only a minuscule sampling. More obscure agencies, such as the recently gutted Consumer Financial Protection Bureau, keep records of corporate trade secrets, credit reports, mortgage information, and other sensitive data, including lists of people who have fallen on financial hardship.

A fragile combination of decades-old laws, norms, and jungly bureaucracy has so far prevented repositories such as these from assembling into a centralized American surveillance state. But that appears to be changing. Since Donald Trump’s second inauguration, Elon Musk and the Department of Government Efficiency have systematically gained access to sensitive data across the federal government, and in ways that people in several agencies have described to us as both dangerous and disturbing. Despite DOGE’s stated mission, little efficiency seems to have been achieved. Now a new phase of Trump’s project is under way: Not only are individual agencies being breached, but the information they hold is being pooled together. The question is Why? And what does the administration intend to do with it?
