Investigation: Palantir analyzes EU citizens' messages under Chat Control

A temporary EU law allows tech companies to scan private messages for child abuse material, then share data with U.S. firm Palantir.

What to know

  • EU citizens' private messages scanned under the temporary Chat Control law since 2021 are being analyzed by Palantir software before being shared with the U.S. National Center for Missing & Exploited Children.
  • Tech companies processed at least 22 million images and 2+ million videos from EU users in 2024 alone; NCMEC received 21 million abuse reports in 2025, processed by only 25 analysts relying on Palantir's algorithms.
  • EU legislators and security experts—including those who helped design Chat Control—were unaware Palantir was involved, raising questions about transparency and oversight of the data pipeline.
  • Palantir is controversial for its CIA origins and current contracts with the Trump administration's ICE and with Israeli military; its role in processing EU citizens' data is now a major privacy and security concern.

The Palantir involvement is a serious scandal that reveals covert mass surveillance of EU citizens and unaccountable data sharing with controversial contractors.

  • “Private chats and emails reported via # ChatControl 1.0 are ending up in # Palantir systems - scandalous!”
