The Financial Conduct Authority started a three-month pilot with Palantir to find financial criminals using artificial intelligence. The regulator pays over £30,000 weekly to test if the Foundry platform can spot money laundering and fraud across 42,000 businesses. This move aims to protect consumers by identifying illicit activities faster than human investigators can manage alone.
FCA pays £30,000 weekly to test Palantir software for fraud detection
The Financial Conduct Authority (FCA) is currently running a high-cost trial of the Foundry platform, a software tool created by Miami-based vendor Palantir. This pilot project costs the regulator more than £30,000 every week to operate. The main goal is to search through the internal data stores of the regulator to find hidden patterns of crime.
Investigators use the software to look for signs of money laundering, insider trading, and general fraud. The FCA oversees 42,000 financial services businesses, making it difficult to watch every transaction manually. By using this software, the regulator hopes to find bad actors who hide their tracks in large amounts of digital information.
This trial marks a shift in how the UK government uses private technology to monitor public markets. If the software works as intended, it will allow the FCA to act against problematic companies much sooner. This change means that businesses under supervision may face more frequent and more accurate checks of their internal records.
Why traditional oversight fails to track modern market data
Standard methods of watching the financial markets often fail because there is too much information to process. Modern markets create a massive volume of data every second, which human teams cannot read or analyze in real time. The FCA has gathered a large "data lake" of information over many years that remains largely unused.
Before this pilot, much of the intelligence held by the regulator was not fully exploited. This includes unstructured data, which is information that does not fit into a simple spreadsheet or database. Examples include audio recordings of phone calls, long email chains, and social media posts from various platforms.
AI platforms like Foundry are built to parse this messy information to find links between different events. For example, the software can connect a phone call to a specific stock trade that happened minutes later. This ability to link different types of evidence helps investigators build stronger cases against people involved in human trafficking or the narcotics trade.
How AI tools scan phone calls and emails to find crime patterns
The software used by the FCA digests a wide variety of inputs to create a map of financial activity. It reads confidential internal files, reports on companies with bad reputations, and complaints sent to the consumer ombudsman. Machine learning tools then listen to audio files and scan archives of digital messages to find keywords or suspicious behavior.
Pattern recognition is the core strength of this technology. Instead of a human reading one email at a time, the AI looks at millions of messages to see who is talking to whom and when. This helps the FCA direct its limited enforcement resources to the areas where the risk of crime is highest.
By automating the first stage of an investigation, the regulator can clear innocent companies faster and focus on real threats. This process turns a mountain of raw data into a list of specific leads for human officers to follow. It changes the role of the investigator from a data collector to a decision-maker.
New rules prevent Palantir from using UK data for its own products
The FCA established strict legal controls before allowing Palantir to access sensitive financial information. Under the current agreement, Palantir acts only as a "data processor," which means they can only do what the FCA tells them to do. The software vendor does not own the data and cannot use it for any other purpose.
One major rule in the contract forbids Palantir from using the ingested information to train its own commercial AI models. This prevents the private company from profiting twice from the regulator's data. Once the three-month pilot ends, the contract requires the vendor to destroy all the information it processed.
To keep the data safe, the FCA keeps the encryption keys for the most sensitive files. This means even if someone at the software company tried to look at the files, they would be unreadable without the regulator's permission. All the information stays on servers located within the UK to ensure national data sovereignty.
Why the regulator chose live financial data over artificial test sets
There is an ongoing debate among technology experts about whether to use synthetic data or live data when testing new AI. Synthetic data is fake information made to look real, which is safer for privacy. However, the FCA decided that the Palantir software needed to be tested in a live environment to see if it actually works.
The regulator determined that artificial datasets could not replicate the complexity of real-world financial crime. To find a clever criminal, the software must deal with the same messy and incomplete data that human investigators see every day. This decision means the pilot uses actual records from real companies and individuals.
Using live data provides a more accurate picture of how the software will perform during a real enforcement action. It shows whether the AI makes too many mistakes or if it can truly find a "needle in a haystack." This approach ensures that the regulator does not buy expensive software that fails when it matters most.
Risks to personal privacy during large scale data mining
When the FCA investigates a company, it often collects records that include details about innocent people. These datasets can contain personal bank details, private telephone numbers, and communication logs of people who are only tangentially related to a case. Using AI to scan these files raises concerns about how much the government knows about private citizens.
The risk is that an automated system might flag an innocent person as a suspect because of a random connection. While the FCA claims to have strict data protection controls, the sheer scale of the data mining makes total privacy difficult to guarantee. If the software makes a mistake, it could lead to unnecessary stress or legal costs for individuals.
The FCA has not yet responded to specific questions about how it will correct errors made by the AI. Currently, the regulator relies on human oversight to check the work of the machine. However, as the volume of data grows, the pressure to trust the machine's results without a full human review may increase.
Palantir plans £1.5 billion investment in UK defense and technology
The work with the financial regulator is part of a much larger expansion for Palantir within the UK government. In September 2025, the government signed a partnership with the company to help the military make faster decisions. Palantir intends to spend £1.5 billion to make London its main headquarters for European defense operations.
This defense deal is expected to create 350 new jobs and involves a project called the Digital Targeting Web. Military planners use the software to combine secret intelligence with public information to find and neutralize targets. The agreement could be worth up to £750 million over the next five years.
As part of this deal, Palantir has agreed to help smaller British tech startups. They will provide free mentoring to help these local firms sell their products in the United States. This suggests the UK government is trying to build a wider ecosystem of technology companies that can work together on national security.

The adoption of Palantir’s software by the FCA represents a fundamental change in how the UK polices its financial borders. By moving away from manual sampling and toward total data coverage, the regulator is attempting to close the gap between criminal innovation and legal enforcement. This transition suggests that the future of financial regulation will depend more on software engineers than on traditional auditors.
The success of this pilot will likely determine if other UK departments adopt similar AI tools for their own investigations. While the efficiency gains are clear, the long-term impact on privacy and the power of private tech firms in government remains a subject of intense debate. The final result of this trial will show if a machine can truly master the complex world of human greed and financial crime.
Frequently Asked Questions
What is the FCA Palantir pilot?
The FCA Palantir pilot is a three-month test of an artificial intelligence platform called Foundry. The regulator is using the software to scan its internal data to find signs of money laundering and fraud. It costs the UK taxpayer more than £30,000 every week during the trial period.
Is my personal financial data safe with Palantir?
The FCA claims that all data is protected by strict controls and remains on UK-based servers. Palantir acts only as a data processor and does not own the information or have the keys to open the most sensitive files. The contract requires the company to destroy all data once the pilot project ends.
Will the FCA use AI to monitor all UK bank accounts?
The FCA currently uses the AI to scan its own internal data lake, which includes reports and complaints it has already collected. While it oversees 42,000 firms, the software is not a direct window into every private bank account in the country. It is a tool for investigators to find patterns in the information they are legally allowed to hold.
