Documents offer rare insight on Ice’s close relationship with Palantir

For years, little was known about the multibillion-dollar company that handles data for the US immigration enforcement agency. Now, a cache of emails, training documents and reports sheds light on how Palantir helps Ice with investigations and on-the-ground enforcement

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.
