Top data stories of 2025

Lexology Pro highlights the most significant data and privacy developments of 2025, from a controversial EU digital omnibus initiative to landmark rulings on Artificial Intelligence and data transfers.

Lexology Pro’s roundup of the top data stories of 2025 focuses on a year defined by regulatory shifts, cross border enforcement, and early case law on Artificial Intelligence and copyright. The article highlights a controversial European Union digital omnibus package that seeks to consolidate and update a wide range of digital and data related rules, positioning it as one of the most consequential policy moves of the year for companies operating across the bloc. The omnibus initiative is presented as a key driver of change for data protection, online safety, and platform regulation in the European Union.

Another major theme is the outcome of the United Kingdom’s first Artificial Intelligence copyright court case, which is described as a landmark for resolving how existing intellectual property rules apply to machine generated content. The decision is framed as an important early signal for developers, rights holders, and users of Artificial Intelligence tools, with implications for how training data, output ownership, and infringement risk will be assessed under United Kingdom law. Alongside this, the piece notes the ongoing rollout of the EU Artificial Intelligence Act and its interaction with long standing privacy legislation such as the gdpr, which together are reshaping compliance strategies for organisations that process personal data or deploy Artificial Intelligence systems.

The roundup also underscores cross border data transfer disputes and enforcement activity involving European and United States regulators. It flags the role of the European Commission, the European Court of Justice, the European Data Protection Board, the Ireland Data Protection Commission, the Information Commissioner’s Office in the United Kingdom, and the United States Federal Trade Commission in shaping enforcement trends, including cases concerning non material damages and alleged misuse of personal data by large platforms such as Meta. The article situates these developments within the evolving framework of the trans atlantic data privacy framework, ongoing debates over data breach notification and cybersecurity obligations, and the practical challenges of maintaining compliance in a rapidly changing regulatory landscape.
