The government wanted us to believe that a massive US tech corporation could save the NHS from its own backlogs. When Palantir won the £330 million contract to build the Federated Data Platform (FDP) in late 2023, the narrative was simple. They promised that tracking patient data through centralized software would magically clear the post-pandemic waiting lists.
It hasn't worked out that way.
By June 2026, the entire deal is teetering on the edge of collapse. Health ministers are quietly telling NHS trusts to prepare for the possibility of ditching Palantir entirely. A cross-party group of MPs on the Science, Innovation and Technology Committee is openly demanding that the government trigger a critical break clause in the contract come February 2027.
The official line from the tech giant and NHS England was that the system had already cleared hundreds of thousands of backlogs. But recent investigations have exposed those claims as mostly smoke and mirrors. The data shows that the reality on the hospital floor looks completely different from the marketing brochures.
The Myth of the Universal Data Fix
If you look at the promotional material, the software looks like a triumph. Proponents point to more than 100,000 extra procedures and a huge drop in hospital discharge delays.
But look closer at the numbers. A major data analysis in June 2026 revealed that these spectacular gains are driven by just a tiny handful of overachieving hospitals. In fact, a single provider—Chelsea and Westminster Hospital NHS Foundation Trust—accounts for a staggering 84 percent of the total decline in outpatient waiting lists cited across sixteen early-adopting trusts.
For the rest of the country, the platform isn't doing much at all. Freedom of Information data obtained by the campaign group Foxglove reveals that nearly 30 percent of the hospital trusts actively using the system have actually seen a decline in the number of operations they perform.
Instead of an easy fix for administrative chaos, many hospitals are finding that implementing a massive, centralized database just adds another layer of bureaucratic friction. Doctors and nurses are already stretched to their absolute limits. Forcing them to adapt to an unfamiliar, highly complex software ecosystem has slowed things down rather than speeding them up.
The Sovereignty Problem and French Lessons
The rebellion against the software isn't just about disappointing performance metrics. It's about a deep, structural discomfort with handing the keys to British health data over to a foreign defense contractor.
Palantir didn't start in healthcare. The firm built its reputation and its massive valuation by working with US intelligence agencies, the CIA, and the military. Its tools have been used for predictive policing, tracking undocumented immigrants for ICE raids, and targeting operations in active war zones.
This background makes British medical professionals incredibly uneasy. The British Medical Association (BMA) has been vocal in its opposition, warning that embedding a secretive American defense contractor into the infrastructure of public health will destroy patient trust. If people worry that their intimate medical histories are being managed by a company with deep ties to foreign intelligence and military operations, they will stop sharing vital information with their doctors.
The UK is not alone in waking up to these risks. In June 2026, France's domestic intelligence agency, the DGSI, announced it was completely dropping Palantir in favor of a domestic French firm called ChapsVision. French Prime Minister Sébastien Lecornu didn't mince words, stating plainly that the country cannot rely on data tools developed by foreign powers because it creates a dangerous strategic dependency.
Members of Parliament in Westminster are looking across the English Channel and asking why the UK is doing the exact opposite. Dame Chi Onwurah, chair of the Science, Innovation and Technology Committee, has warned that depending on a small group of massive US tech firms leaves the entire British state seriously exposed.
The Single Patient Record Battleground
The stakes are rising because the government is currently pushing through a new health bill that includes the creation of a Single Patient Record. The goal is to create one unified digital file for every single citizen in the country, connecting everything from your GP visits to your major hospital surgeries.
This is where the fight gets incredibly messy.
If Palantir stays in place, their FDP will likely form the core architecture where these records live. That means a single US company could hold the keys to the health data of tens of millions of British citizens. MPs are pushing hard to ensure that this upcoming single record project uses UK-owned and UK-based suppliers instead.
We also have a transparency crisis. When the original contract was finally published after intense public pressure, it looked like a document from an intelligence agency. Over 200 pages were completely blacked out. The redactions covered crucial details about how personal data would be protected and who exactly would have access to it.
To make matters worse, NHS England recently had to apologize for giving incorrect information to the National Data Guardian. They had claimed that the company had no direct access to patient information within the platform, a statement that turned out to be completely false. When a public health body can't even get its story straight about who can see your medical records, public trust evaporates fast.
What Happens Next
The Department of Health and Social Care is currently running a commercial review of the contract, which should wrap up by early autumn of 2026. December is the absolute latest deadline for the government to inform the supplier if they intend to walk away, but ministers want to make the call sooner.
If you are running an NHS trust or working in healthcare leadership, you can't just wait around to see what happens. The momentum has shifted dramatically against the current arrangement.
The smartest move right now is to freeze any massive local rollouts and prepare an exit strategy. Health Minister Stephanie Gill confirmed to a parliamentary committee that a specific program of work is already underway within the health service to minimize disruption if the contract is torn up.
Hospitals need to focus on building open-source, locally controlled data solutions that comply with strict UK privacy laws rather than locking themselves into a proprietary foreign ecosystem that might be illegal to use in two years. The French model proved that pulling the plug on foreign data monopolies is entirely possible if you build the domestic infrastructure to support it. The NHS needs to start building that alternative today before the February 2027 deadline forces their hand.
