The United Kingdom’s financial regulators have quietly handed over vast quantities of sensitive financial data to Palantir Technologies, the American data analytics firm co-founded by Peter Thiel, in a move that has triggered sharp criticism from privacy advocates and raised uncomfortable questions about the growing entanglement between government oversight bodies and Silicon Valley’s surveillance apparatus.
The arrangement, first reported by TechRadar, involves the Financial Conduct Authority sharing regulatory data with Palantir’s platform to bolster efforts against financial crime. The FCA confirmed the partnership is designed to improve the detection of fraud, money laundering, and other illicit financial activity across the UK’s sprawling financial services sector. On paper, the rationale sounds straightforward enough. Financial crime costs the UK economy billions annually. Traditional detection methods are slow, siloed, and often overwhelmed by the sheer volume of modern transactions. Palantir’s software — originally built for intelligence agencies — promises to knit together disparate data sources into a single analytical framework that can spot patterns human analysts would miss.
But the implications run far deeper than operational efficiency.
Palantir is no ordinary technology vendor. The company, headquartered in Denver, built its reputation — and its early revenue — on contracts with the CIA, the NSA, and the U.S. Department of Defense. Its Gotham platform became a backbone of American counterterrorism operations. Its Foundry product later found traction in commercial markets. And its expansion into government health systems during the COVID-19 pandemic drew intense scrutiny in the UK, where the National Health Service awarded Palantir contracts worth hundreds of millions of pounds to manage patient data. The company’s involvement in UK financial regulation represents another significant expansion of its footprint across British public institutions.
Privacy campaigners aren’t mincing words. “There are very significant privacy concerns here,” said one critic quoted by TechRadar, reflecting a broader unease about the transfer of financial regulatory data — information that can include details about individuals, firms, transactions, and investigations — to a private company with deep roots in military and intelligence work.
The core anxiety is this: once data enters Palantir’s platform, what happens to it? Who has access? How long is it retained? And what safeguards exist to prevent mission creep — the gradual expansion of data use beyond its original purpose?
These are not hypothetical concerns. Palantir’s track record includes involvement in U.S. Immigration and Customs Enforcement operations, where its software was used to help identify and track undocumented immigrants. That history has made the company a lightning rod for civil liberties organizations on both sides of the Atlantic. When the NHS initially awarded Palantir a data contract during the pandemic, campaigners from openDemocracy and Foxglove mounted legal challenges, arguing that the public had not been adequately consulted about handing sensitive health records to a firm with such a controversial background.
The FCA’s arrangement follows a similar pattern of quiet adoption. There was no major public announcement. No parliamentary debate. The details emerged through reporting rather than proactive disclosure, a fact that has itself become a point of contention.
So what exactly is the FCA sharing? The authority collects enormous volumes of data as part of its supervisory and enforcement functions. This includes transaction reports filed by regulated firms under the Markets in Financial Instruments Directive (MiFID II) framework, suspicious activity reports, corporate filings, individual registration data for approved persons, and information gathered during investigations. The precise scope of what’s been made available to Palantir hasn’t been fully detailed publicly, but the FCA has indicated the goal is to improve its analytical capabilities across multiple data sets simultaneously — exactly the kind of cross-referencing that Palantir’s software is designed to perform.
For Palantir, the contract is a strategic prize. The UK is one of the world’s largest financial centers. Getting embedded in the country’s primary financial regulator provides not just revenue but credibility — a reference client that could open doors to similar arrangements with regulators across Europe, Asia, and beyond. The company’s stock has surged dramatically over the past year, driven in part by investor enthusiasm about its growing government and commercial client base. Palantir reported revenue of $2.87 billion for fiscal year 2024, with government contracts still accounting for a substantial share.
The timing matters. Britain has been aggressively positioning itself as a post-Brexit hub for financial innovation and regulatory technology, or regtech. The FCA has publicly embraced the idea that technology can make supervision faster and more effective. Its 2023-2025 strategy explicitly calls for greater use of data and analytics. Partnering with Palantir fits that agenda — but it also raises the question of whether the regulator has adequately weighed the privacy trade-offs.
And those trade-offs are real. Financial data is among the most sensitive categories of personal information. Transaction records can reveal where someone shops, what they spend on healthcare, their political donations, their religious affiliations, their romantic relationships. Aggregated at scale, such data paints an extraordinarily detailed portrait of individual lives. When a government regulator feeds that information into a platform built by a company whose other clients include military and intelligence agencies, the potential for abuse — however theoretical — cannot be dismissed.
The UK’s Information Commissioner’s Office, the independent body responsible for data protection, has not publicly commented on the FCA-Palantir arrangement. Under the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018, the FCA would need to demonstrate a lawful basis for sharing personal data with a third-party processor, conduct a Data Protection Impact Assessment, and ensure adequate contractual safeguards are in place. Whether these steps have been taken — and whether they’re sufficient — remains unclear.
Palantir, for its part, has consistently pushed back against privacy criticisms. The company argues that its software is designed with strict access controls, that data remains under the control of the client organization, and that its platforms actually enhance privacy by allowing analysts to work with data in a controlled environment rather than copying it across multiple systems. Alexander Karp, Palantir’s CEO, has repeatedly made the case that the company’s technology helps democratic governments enforce laws more effectively while maintaining civil liberties. Critics find this framing unconvincing.
There’s a broader pattern here that extends well beyond one regulator and one vendor. Governments around the world are increasingly turning to private technology firms to handle functions that were once considered inherently governmental. Tax collection, border security, welfare administration, criminal justice — all have seen growing private-sector involvement, often with limited public debate. The UK has been particularly aggressive in this regard. Palantir’s NHS contracts. Amazon Web Services hosting classified government data. Fujitsu’s catastrophic role in the Post Office Horizon scandal. Each case illustrates the risks that arise when public institutions become dependent on private technology providers whose incentives, governance structures, and accountability mechanisms differ fundamentally from those of the state.
The financial crime argument is compelling on its own terms. The UK’s National Crime Agency has estimated that money laundering costs the country more than £100 billion annually. Fraud now accounts for over 40% of all crime in England and Wales. Banks and financial institutions file hundreds of thousands of suspicious activity reports each year, many of which go uninvestigated simply because regulators lack the analytical capacity to process them. If Palantir’s technology genuinely helps the FCA identify criminal networks faster, the public benefit could be substantial.
But benefit alone doesn’t settle the question. The history of surveillance technology is littered with programs that began with legitimate aims and expanded far beyond their original scope. The NSA’s bulk metadata collection program, revealed by Edward Snowden in 2013, started as a counterterrorism tool. The UK’s own Investigatory Powers Act — dubbed the “Snoopers’ Charter” — was justified on national security grounds but grants authorities sweeping powers to access communications data. Once infrastructure exists, it tends to get used.
What’s missing from the current arrangement, critics argue, is transparency. The FCA has not published a detailed account of what data is being shared, what Palantir’s platform does with it, what retention policies apply, or what independent oversight mechanisms are in place. For a regulator whose own mandate includes ensuring that regulated firms treat customers fairly and protect their data, the opacity is striking.
Parliament has shown intermittent interest in Palantir’s expanding role in UK government. Several MPs raised questions during debates over the NHS data contracts. But sustained scrutiny has been lacking. The House of Commons Treasury Select Committee, which oversees the FCA, has not announced any inquiry into the Palantir partnership. Nor has the House of Lords Communications and Digital Committee, which has examined AI governance issues more broadly.
Meanwhile, Palantir continues to expand. The company recently won a major contract with the U.S. Army, secured a deal with the Italian government, and has been courting financial institutions in Europe and the Middle East. Its Artificial Intelligence Platform (AIP), which integrates large language models with its existing data analytics tools, has become a major selling point. The company is positioning itself not just as a data processor but as the operating system for government decision-making — a proposition that should give democratic societies pause.
None of this means the FCA’s decision is necessarily wrong. Financial crime is a serious problem. Technology can help. And Palantir’s software, whatever one thinks of the company, is widely regarded as technically capable. The question is whether the regulatory and democratic safeguards surrounding this kind of arrangement are adequate — and right now, the evidence suggests they aren’t.
The UK finds itself at a familiar crossroads. The pressure to modernize, to move faster, to match the sophistication of criminal networks is real and urgent. But so is the obligation to protect the rights of millions of people whose financial data is now flowing through systems built by a company that answers primarily to its shareholders. Getting that balance wrong wouldn’t just be a policy failure. It would be a betrayal of the very principles that financial regulation is supposed to uphold.
