Regulated companies face enhanced CNMC scrutiny through AI and data analysis

Real Decreto 825/2026, published in the BOE, modifies the Organic Statute of the National Commission on Markets and Competition (CNMC) to significantly bolster its economic and technological analytical capabilities. This legislative update introduces two pivotal structural changes: the creation of the Chief Economist position and the establishment of the Economic Intelligence Sub-directorate, both designed to modernize the authority's approach to market supervision and competition defense.

What changes

The reform focuses on upgrading the CNMC's technical infrastructure to match the complexity of modern digital markets. The key modifications are as follows:

• The Chief Economist: Under art. 31 ter, a Chief Economist will be appointed to provide specialized economic advice directly to the Presidency. This role is designed to be horizontal, meaning it provides support across all Commission organs, particularly in high-complexity cases involving competition defense, regulation, and supervision. The Chief Economist is also tasked with maintaining ties with the academic and scientific community to ensure the Commission's methodologies remain at the cutting edge.
• Economic Intelligence Sub-directorate: As established in art. 31 ter.1 and 31 ter.2, this new sub-directorate will operate under the Chief Economist. Its primary mandate is to develop new quantitative analysis tools, business intelligence, and data processing systems. Specifically, the sub-directorate will apply statistics and artificial intelligence to assist the Commission's organs (art. 31 ter.2.c).
• Enhanced Detection Capabilities: The new structure explicitly empowers the Commission to use these technological tools to support investigation departments in detecting and investigating behaviors that contravene competition and sectoral regulations (art. 31 ter.2.d).

Context

This Royal Decree modifies the existing Organic Statute of the CNMC, which was originally approved by Real Decreto 657/2013. Specifically, it modifies art. 36.2 and introduces new articles, 31 bis and 31 ter, into the framework previously updated by Real Decreto 729/2023. The reform is driven by the necessity to adapt to the digitalization of markets and the increasing use of big data. The preamble of the decree notes that the sophistication of economic analysis techniques and the emergence of new market dynamics require a proportionate increase in the Commission's technical resources to ensure the quality and accuracy of its decisions. This move aligns the CNMC with international trends where competition authorities are increasingly relying on algorithmic monitoring and data-driven enforcement, a landscape where the data protection ai act intersection becomes a critical consideration for regulated entities.

Who is affected and how

While this regulation is an internal organizational reform of a public body, its practical impact on the private sector is profound, particularly regarding the intensity and method of supervision.

• Large Companies and Market Operators: Entities with significant market share or those operating in highly regulated sectors (such as energy, telecommunications, or digital platforms) will face a more technologically advanced regulator. The use of AI and big data by the CNMC means that patterns of anti-competitive behavior that were previously difficult to detect through manual audits may now be identified through automated quantitative analysis. Companies must ensure their data reporting and market conduct are robust enough to withstand sophisticated algorithmic scrutiny.
• SMEs (Small and Medium Enterprises): Any SME subject to CNMC supervision in matters of competition or sectoral regulation will be part of a more efficient regulatory environment. While the technical sophistication of the CNMC might seem distant, the increased efficiency in detecting market distortions can lead to a more level playing field for smaller players who are often the victims of anti-competitive practices by larger incumbents.
• Regulated Sectors: Industries such as energy and technology will experience a shift in how compliance is monitored. The creation of the Economic Intelligence Sub-directorate implies that the CNMC will move toward a more proactive, data-driven oversight model rather than a purely reactive one.

What to do and when

This Royal Decree is an administrative reorganization of the CNMC and does not impose new direct obligations, filing requirements, or sanctions on private companies or individuals. Therefore, there is no specific compliance calendar or adaptation period required for businesses to follow.

However, from a strategic perspective, companies should be aware that the CNMC's ability to conduct investigations will be enhanced. The entry into force of this decree is the day following its publication in the BOE, which corresponds to October 16, 2026 (disposición final única). Organizations should consider reviewing their internal data management and competition compliance protocols to ensure they are prepared for a regulator that will increasingly utilize artificial intelligence and advanced statistical modeling in its oversight duties.
