GoKawiilPalantir is to be granted access to a trove of highly sensitive UK financial regulation data, in a deal that has prompted fresh concerns about the US AI company’s deepening reach into the British state, the Guardian can reveal.
The Financial Conduct Authority (FCA) has awarded Palantir a contract to investigate the watchdog’s internal intelligence data in an effort to help it tackle financial crime, which includes investigating fraud, money laundering and insider trading.
The Miami-based company, co-founded by the billionaire Donald Trump donor Peter Thiel, has been appointed for a three-month trial, paying more than £30,000 a week to analyse the FCA’s vast “data lake”, which could lead to a full procurement of an AI system.
The deal is part of the FCA’s drive to use digital intelligence to better focus resources on rule-breaking among the 42,000 financial services firms it regulates, from major banks to crypto exchanges.
There was only one other, unnamed competitor for the contract. Palantir already has more than £500m in UK public deals, including with the NHS, military and police.
The contract has prompted warnings of “very significant privacy concerns”. Palantir is expected to apply its AI system, known as Foundry, to huge quantities of information held by the watchdog, including case intelligence files marked highly sensitive; information on so-called problem firms; reports from lenders about proven and suspected frauds; and data about the public, including consumer complaints to the financial ombudsman.
The data includes recordings of phone calls, emails and trawls of social media posts, the Guardian understands. The FCA is one of several UK agencies which aim to stop financial crimes that underpin harms such as the drug trade and human trafficking.
The deal has raised concerns inside the FCA. One source said: “Once Palantir understands how we detect money-laundering threats, how do we know that they are ethically reliable enough not to go to share that information?”
Palantir’s technology is used by the Israeli military and in the US president’s ICE immigration crackdown, leading to leftwing MPs in the House of Commons last month to call it a “highly questionable” and “ghastly” company. In 2023 it signed a £330m deal with the NHS, which has sparked resistance from doctors, and a £240m contract with the Ministry of Defence in December 2025, which prompted MPs to highlight “reports of serious allegations of complicity in human rights violations and the undermining of democratic processes made against Palantir”.
Palantir has previously defended its work, saying it has led to about 99,000 extra operations being scheduled in the NHS, helped UK police tackle domestic violence and that it “takes a rigorous approach to respecting human rights”.
