Registered nurses across the United States are mobilising today, August 27, in what National Nurses United says is its largest coordinated national action yet against Palantir. Nurses, patients and community allies are calling on hospitals and elected officials to cut ties with the technology company, arguing that the debate is no longer simply about artificial intelligence inside hospitals. It is about who controls sensitive data, how technology is used beyond healthcare, and what safeguards should exist when public institutions depend on powerful technology companies.

National Nurses United, the largest union of registered nurses in the United States, has become one of Palantir's most vocal healthcare critics. The union argues that the company's expanding presence across hospitals, public services and federal agencies raises questions about privacy, workforce autonomy and the growing influence of technology companies over public infrastructure. NNU material published earlier this year says at least 15 U.S. hospital systems use Palantir and cites company executives as saying its technology manages activity connected with roughly 21 per cent of U.S. hospital beds. The union says hospital deployments include bed allocation, staffing, scheduling and interactions with insurers.

The protests are planned across Palo Alto, Los Angeles, Chicago, Washington D.C., Portland in Maine, Asheville, Austin and New Orleans. NNU is deliberately connecting Palantir's role in healthcare with its work for the U.S. government. The union says demonstrators will highlight people, including children, affected by immigration detention and enforcement, arguing that the same debate about data infrastructure cannot be separated neatly into a healthcare side and a government side.

That concern has gained substance through reporting about a Palantir-linked system known as ELITE, short for Enhanced Leads Identification and Targeting for Enforcement. Reporting discussed on PBS describes ELITE as a tool used by Immigration and Customs Enforcement to assemble information on individuals, map potential enforcement targets and calculate confidence scores for addresses. According to investigative reporting discussed by PBS, ICE officials have testified about using ELITE to construct target lists and identify areas described by officials as target rich.

The data question is particularly significant for healthcare. PBS also reported on a data-sharing agreement under which ICE obtained personal information relating to nearly 80 million Medicaid patients, including names, addresses and other sensitive information. The reporting described a wider ecosystem in which information from different government and insurance sources could be brought together to help locate individuals. That does not mean Palantir's NHS systems operate in the same way, nor does it establish that NHS patient information is being used for U.S. immigration enforcement. It does, however, explain why American nurses are demanding a much broader conversation about the boundaries surrounding health data.

For nurses, that argument also reaches directly onto the hospital floor. Their concern is that systems initially presented as tools for efficiency can increasingly influence staffing, scheduling, patient flow and operational decision-making. Used well, technology can give clinicians better information, reduce wasted capacity and help patients receive treatment faster. Used without sufficient clinical oversight, transparency or accountability, it can create another layer of control between healthcare professionals and the patients they serve.

NNU President Jamie Brown, RN, has framed the dispute in even wider terms, linking nurses' experiences of patients frightened by immigration enforcement with growing scarcity inside hospitals. The union's position is that decisions about public resources, healthcare capacity and patient data should not migrate by default into the hands of technology companies simply because their platforms are technically capable of managing them.

That argument should attract attention in Britain.

Palantir has become deeply associated with the NHS's Federated Data Platform, one of the most important data infrastructure programmes in English healthcare. The case for better NHS data infrastructure is compelling. Hospitals need to understand waiting lists, theatres, beds, workforce, diagnostics and discharge pathways more effectively. Fragmented information costs time and ultimately harms patients.

But the American protests introduce a different question. The issue is no longer simply: does the software work?

It is: what degree of dependency should a national health service develop on any one private technology supplier? Who controls the architecture around patient information? How portable are NHS capabilities if government later changes supplier? What can clinicians and patients see about how decisions are made? And how should Britain assess a technology company's activities elsewhere when deciding whether it should occupy a strategically important position inside public healthcare?

Those questions become more important as AI moves from analysing healthcare into actively orchestrating it. A platform that helps predict demand or find unused theatre capacity is one thing. A platform that increasingly influences staffing, prioritisation, operational command and resource allocation becomes part of the institutional machinery of healthcare itself.

The NHS therefore does not need an anti-technology response. It needs a stronger pro-accountability one.

Britain should demand interoperability, independent clinical governance, clear restrictions on secondary uses of patient data, auditable algorithms, genuine supplier portability and transparent rules governing how information can move between systems. The NHS should also continue developing a diverse technology ecosystem rather than allowing any single vendor to become effectively irreplaceable.

The protests taking place across America today matter because nurses are forcing a question that healthcare systems everywhere will increasingly face.

Artificial intelligence may become indispensable to modern healthcare. That does not mean any company providing it should become indispensable to the health system.

The message emerging from American nurses is therefore bigger than “Palantir Out.”

It is that healthcare professionals and patients want a meaningful say in what technology comes in, what information it can access, what decisions it is allowed to influence and where the limits are drawn.

For the NHS, that debate may only just be beginning.
