The UK’s Competition and Markets Authority (CMA) has taken the first formal step in reviewing the proposed acquisition of Warner Bros. Discovery by Paramount Skydance Corporation, opening a public consultation process that could precede a full merger investigation.
Announced on 13 April 2026, the CMA’s move does not yet mark the start of a formal Phase 1 inquiry. Instead, the authority has issued an “invitation to comment,” a preliminary stage designed to gather views from market participants, competitors, and other stakeholders on the potential competitive impact of the transaction in the UK.
This consultation period, which runs until 27 April 2026, forms part of the CMA’s early information-gathering process. During this time, interested parties are encouraged to submit observations on how the merger might affect competition across the communications sector. Such input can play a critical role in shaping the authority’s decision on whether to proceed with a formal investigation.
The transaction itself—combining major global media and entertainment assets—raises the prospect of consolidation in content production, distribution, and streaming services. Warner Bros. Discovery is a major player in film, television, and direct-to-consumer platforms, while Paramount Skydance brings together established studio operations with growing ambitions in global media. A merger between the two could alter competitive dynamics in areas ranging from premium content licensing to streaming platform rivalry.
At this stage, however, the CMA has not expressed any substantive concerns, nor has it confirmed whether it will open a Phase 1 investigation. The authority has indicated that it has received sufficient information from the parties to begin pre-notification discussions, a typical precursor to a formal review.
The use of an invitation to comment highlights the CMA’s continued emphasis on early stakeholder engagement in merger control. By soliciting market feedback before launching a formal probe, the regulator aims to identify potential competition issues at an early stage and ensure that its subsequent analysis is grounded in market realities.
Should the CMA decide to proceed, the case would enter Phase 1, where the authority would assess whether the merger could result in a substantial lessening of competition in the UK. Given the scale and international reach of the companies involved, the review is likely to attract close scrutiny not only in the UK but also from other competition authorities worldwide.
For now, the process remains at an exploratory stage. However, the opening of this consultation signals that regulators are preparing to examine closely what could become one of the most consequential media mergers in recent years.
