Event Summary

Palantir is challenging the decision by London mayor Sadiq Khan's office to block a £50 million contract with the United Kingdom — Metropolitan Police. The contract would have provided AI systems for evidence analysis and automation. The mayor's office cited procurement issues and concerns about Palantir's values and ethics. Palantir argues the decision unlawfully considered its values and ethics. A trial is scheduled for January 2027. Separately, the UK is reviewing a £330 million NHS contract with Palantir, and a parliamentary committee recommended using a break clause, which Palantir's UK CEO Louis Mosley called irresponsible.
