United States Immigration and Customs Enforcement is using Palantir’s generative artificial intelligence tools to help process immigration enforcement tips submitted through a public form, according to a Department of Homeland Security AI inventory for 2025.
The disclosure adds new detail to Palantir’s long-running work with ICE. It also shows how AI is being placed inside a workflow that begins with public tips and can move into investigative review, database checks, reports, and referrals inside DHS.
What The New ICE Tip System Does
The system is listed as AI Enhanced ICE Tip Processing. According to the DHS inventory, it is intended to help ICE investigators “to more quickly identify and action tips” in urgent cases.
The tool also translates submissions that are not made in English. In addition, it produces a “BLUF,” which the inventory defines as a “high-level summary of the tip.” The summary is generated using at least one large language model.
BLUF stands for “bottom line up front.” The source article notes that the phrase is a military term and is also used internally by some Palantir employees.
DHS says the software is “being actively authorized” to support ICE operations. The inventory says it is meant to reduce the “time-consuming manual effort required to review and categorize incoming tips.”
The listed operational date for the AI-enhanced tip processing system is May 2, 2025.
What DHS Says About The AI Models
The DHS inventory gives limited detail about the large language models used by Palantir to create the BLUF summaries. It says ICE uses “commercially available large language models” that were “trained on the public domain data by their providers.”
The inventory also states: “There was no additional training using agency data on top of what is available in the models’ base set of capabilities.” It adds: “During operation, the AI models interact with tip submissions.”
That distinction matters because the inventory separates model training from model operation. Based on the source, DHS says agency data was not used for additional training, while also saying the models interact with submitted tips when the system is running.
The “2025 DHS AI Use Case Inventory” was published Wednesday on DHS’s website. The source article says DHS has published the inventory every year since 2022, and that the 2024 version did not mention using AI to process tip line submissions.
How Palantir Fits Into ICE’s Existing Systems
Palantir has been a major ICE contractor since 2011 and provides analytical tools for the agency. Until this disclosure, the source article says little was known about Palantir’s work on ICE tip processing.
One earlier reference appeared in the description of a $1.96 million Palantir payment made by ICE in September 2025. That payment modified the Investigative Case Management System, or ICM, to include the “Tipline and Investigative Leads Suite.”
ICM is described as a version of Palantir’s law enforcement product, Gotham. It stores information about current or former ICE investigations.
The payment description did not provide further detail about the “Tipline” integration. The source article also says the AI Enhanced ICE Tip Processing tool may be an update to the “FALCON Tipline,” which replaced ICE’s previous tip-processing system around 2012.
According to a DHS document last updated in 2021, the FALCON Tipline processes tips submitted by the public or by law enforcement agencies about “suspected illegal activity” or “suspicious activity” to ICE’s Homeland Security Investigations Tipline Unit. The source article says ICE appears to have only one tip line, with submissions made online or by phone.
Where Tips Can Go After Submission
An entry to a federal register in December 2025 describes what happens when HSI receives a tip. Investigators in the Tipline Unit conduct “queries” across “DHS, law enforcement, and immigration databases.”
After reviewing those results, HSI agents write “investigative reports” and refer tips to the appropriate DHS offices. The source article says it is unclear how much of this workflow may now be assisted by AI-enhanced processing.
Data from the FALCON Tipline, Palantir’s ICM, and several other databases are also ingested and made searchable by the FALCON Search & Analysis System. That tool was also developed by Palantir.
The result is a tip-processing environment that appears to combine public submissions, investigative systems, searchable databases, and AI-generated summaries. The source does not say that the AI decides what happens to a tip. It says the system helps sort, summarize, translate, and support faster review.
Internal Pressure And Related AI Tools
After federal agents shot and killed Minneapolis nurse Alex Pretti on Saturday, Palantir workers pressed company leadership for answers about its ICE work. In Slack messages reviewed by WIRED this week, workers asked whether Palantir could “put any pressure on ICE at all.”
One worker wrote, “Our involvement with ice has been internally swept under the rug under Trump2 too much. We need an understanding of our involvement here.”
Palantir leadership then updated an internal wiki about its work with ICE. In a post from January 24, Akash Jain, whose LinkedIn profile lists him as chief technology officer and president of Palantir USG, defended the work by writing that Palantir’s services improve “ICE’s operational effectiveness.”
The wiki describes Palantir’s ICE work as focused on three areas: “Enforcement Operations Prioritization and Targeting,” “Self-Deportation Tracking,” and “Immigration Lifestyle Operations focused on logistics planning and execution.” It does not mention AI use for sorting immigration enforcement tips.
The DHS inventory also references Enhanced Leads Identification & Targeting for Enforcement, or ELITE, another Palantir-developed tool first reported by 404 Media earlier this month. ELITE creates maps of potential deportation targets and presents information dossiers on each person. It pulls data from the Department of Health and Human Services to identify addresses for potential targets.
According to the inventory, ELITE became operational in June. 404 Media reports that it has been used in Oregon.
Palantir did not immediately respond to requests for comment. A DHS spokesperson told WIRED that ICE uses technologies to help with arrests of “criminal gang members, child sex offenders, murderers, drug dealers, identity thieves and more, all while respecting civil liberties and privacy interests.”
The spokesperson added: “Palantir has had federal contracts with DHS for fourteen years. DHS’s current engagement with Palantir is through Immigration and Customs Enforcement, where the company provides solutions for investigative case management and enforcement operations.”
