Documents offer rare insight on Ice’s close relationship with Palantir; The Guardian, September 22, 2025

 Johana Bhuiyan, The Guardian; Documents offer rare insight on Ice’s close relationship with Palantir

"Over the past decade, the US Immigration and Customs Enforcement agency (Ice) has amassed millions of data points that it uses to identify and track its targets – from social media posts to location history and, most recently, tax information.

And there’s been one, multibillion-dollar tech company particularly instrumental in enabling Ice to put all that data to work: Palantir, the data analytics firm co-founded by Peter Thiel, the rightwing mega-donor and tech investor.

For years, little was known about how Ice uses Palantir’s technology. The company has consistently described itself as a “data processor” and says it does not play an active role in any of its customers’ data collection efforts or what clients do with that information.

Now, a cache of internal Ice documents – including hundreds of pages of emails between Ice and Palantir, as well as training manuals, and reports on the use of Palantir products – offer some of the first real-world examples of how Ice has used Palantir in its investigations and during on-the-ground enforcement operations.

The documents, which were obtained by immigrant legal rights group Just Futures Law through a Freedom of Information Act request and reviewed by the Guardian, largely cover Palantir’s contract with Homeland Security Investigations (HSI), the investigative arm of Ice that is responsible for stopping the “illegal movement of people, goods, money, contraband, weapons and sensitive technology”."
