LONDON — The question was never whether Britain’s competition authority would look at the deal. The question was how hard. On Tuesday, the Competition and Markets Authority moved past the preliminary stage and formally opened a Phase 1 investigation into Paramount Skydance Corporation’s $110 billion all-cash acquisition of Warner Bros. Discovery, setting August 7 as the date by which it must deliver an initial ruling.
That deadline, confirmed by Bloomberg, lands just five weeks after the European Commission’s own July 7 deadline — which means David Ellison’s entertainment empire-in-waiting faces the prospect of two major foreign regulatory verdicts arriving in close succession, with a third front still open in Washington. The timing compresses the path to Paramount’s target close in the third quarter of 2026, though neither company has signaled alarm publicly.
The CMA’s Phase 1 review gives the regulator up to 40 working days to assess whether the tie-up between two of Hollywood’s most storied studios — the combined library spanning Casablanca and Batman on the WBD side, The Godfather and Mission: Impossible at Paramount — would substantially lessen competition in the United Kingdom’s film and television markets. If the authority finds a realistic prospect of such harm, the deal advances to a Phase 2 investigation led by an independent inquiry group of three to five specialists, a process that runs up to 24 weeks and carries the power to demand asset sales or block the transaction outright.
That outcome is far from certain, but it is not theoretical. The CMA has in recent years built a reputation for being among the most assertive merger authorities in any major economy, blocking Microsoft’s acquisition of Activision Blizzard in 2023 before eventually clearing a restructured version of the deal. The regulator does not see itself as an obstacle to global dealmaking so much as a guardian of UK market conditions, and its current review of the Paramount-WBD transaction is explicitly framed around what the merger means for consumers and creative workers in Britain specifically — not globally.
What the merger would mean in practice is considerable. The combined company would control CNN and CBS on the news side, HBO and Paramount+ in streaming, and two studio systems with decades of premium intellectual property. In the UK, that translates to significant leverage over broadcasters, streaming distributors, and cinema chains — all of whom have an interest in the outcome of the CMA’s review. The regulator invited public comments in April, drawing responses from entertainment industry figures including actor Mark Ruffalo, who linked directly to the CMA’s merger inquiry page, part of a wider campaign by more than 1,000 writers, directors, and actors opposing the deal on the grounds that it would reduce creative opportunities and limit audience choice.

Paramount and Warner Bros. Discovery did not immediately respond to requests for comment Tuesday. They did not respond to earlier requests during the April consultation period either. That silence has become something of a pattern in the deal’s regulatory phase: the companies have largely declined to engage publicly with the substance of objections, leaving the field to opponents while maintaining that the transaction is pro-competitive and pro-consumer.
The parallel pressure from Brussels is the more immediate constraint. Bloomberg reported last week that the European Commission set its own initial deadline of July 7 after Paramount formally filed for EU clearance. European cinema exhibitors have raised concerns about the merger’s potential to distort theatrical release windows and reduce the variety of content reaching screens in smaller markets. How the Commission characterizes those concerns — whether as manageable through behavioral remedies or as structural competition problems — will set a tone that the CMA cannot entirely ignore.
In the United States, the Hart-Scott-Rodino waiting period expired in February after the Department of Justice issued a second request for information. The expiration of the waiting period does not foreclose a DOJ challenge; it simply means the agency chose not to block the deal before closing during the initial review window. Some lawmakers have separately pressed the Committee on Foreign Investment in the United States to review the role of Middle Eastern sovereign wealth funds in the transaction’s financing. Paramount has said those investors do not meet the threshold triggering a mandatory CFIUS review.
At the center of all of it is Ellison — David Ellison, the son of Oracle founder Larry Ellison — who assembled the financing structure that ultimately beat out Netflix for WBD after one of the most fiercely contested media bidding wars in recent memory. The deal was struck at $31 per share in cash, valuing WBD at $81 billion in equity and $110 billion at the enterprise level. Paramount paid Netflix a $2.8 billion termination fee to exit its prior merger agreement with WBD, a sum that underlines how seriously Ellison pursued the prize. The combined company is expected to generate over $6 billion in annual synergies through technology integration, merged streaming stacks, and corporate consolidation.
Whether those synergies arrive depends entirely on what the regulators decide. The CMA’s Phase 1 clock started Tuesday. What matters now is not the ambition of the deal but whether four letters — three in London, one in Brussels — produce an approval, a demand for remedies, or something that forces the lawyers to start over.
The August 7 ruling date falls before the September 30 deadline by which, under the merger agreement, WBD shareholders begin receiving a 25-cent quarterly ticking fee if the deal has not closed. That sequence gives the CMA its window. What it does with it is what the industry is now watching closely.
