The Agency Landscape Tracker: Where WPP, Publicis, Omnicom, and Dentsu Stand Heading Into 2026

The Agency Landscape Tracker: Where WPP, Publicis, Omnicom, and Dentsu Stand Heading Into 2026

This is the first edition of a recurring quarterly tracker covering the world’s major advertising holding companies. The format is deliberate: no opinion, no commentary dressed up as analysis. Just a structured, fact-based snapshot of where each group stands financially, operationally, and strategically. Q1 2026 earnings have not yet been released as of 23 March 2026. Publicis is scheduled to report Q1 2026 revenue on 16 April 2026, with others following in April and May. This edition uses end-2025 and early-2026 data. For business leaders, marketers, and agency partners tracking advertising holding company performance 2026, this tracker is updated each quarter as results come in.

The Five Groups at a Glance

The table below reflects end-2025 results. These are confirmed figures, not forecasts.

Publicis Groupe: The Clear Outperformer

Publicis ended 2025 with 5.6% organic growth, its second consecutive year above 5%, and claimed the result was approximately 700 basis points ahead of the peer average (which it described as expected to be negative overall). Operating income rose 8.1% to €2.4 billion on net revenues of €14.5 billion. The group added roughly 5,800 staff in 2025, while most rivals were cutting.

The competitive position is now structurally significant. Publicis won 56% of all global new business billings tracked in 2025, totalling 1,458 wins from 3,885 pitches, more than double Omnicom’s 656. Its market capitalisation exceeded €26 billion at end-2024, making it the world’s largest advertising group by that measure. WPP’s confirmed client losses to Publicis include L’Oréal media (moved May 2024), Mars ($1.7bn media), Coca-Cola ($700m US media), and PayPal global media.

The foundation of this run is Marcel, an internal AI platform connecting more than 100,000 staff, announced at Cannes Lions in 2017 and widely mocked at the time. By January 2024, Publicis had invested €300 million over three years in CoreAI, a platform comprising 2.3 billion consumer profiles and decades of transformation data. CEO Arthur Sadoun’s view, stated in March 2026 to Campaign Asia: “Competitors are living in a dream about AI replacing people.” His framing positions Publicis as having built the infrastructure; the bet is now whether rivals can close a self-described six-to-seven-year gap.

Omnicom + IPG: The Merger Entity Takes Shape

The merger of Omnicom and Interpublic Group, announced at end-2024, closed in December 2025 following FTC and EU regulatory clearance. The combined entity employs 120,000 people. On 1 December 2025, the group announced 4,000 redundancies as part of post-merger restructuring. Combined, Omnicom and IPG shed approximately 8,200 roles in 2025 (IPG lost 3,200 in the first nine months; Omnicom approximately 5,000).

The financial target is aggressive. The savings goal has been doubled from $750 million to $1.5 billion: $1 billion in labour, $240 million in real estate, and $260 million across IT, procurement, and operations.

Brand consolidation is proceeding at pace. DDB and MullenLowe have been retired as standalone brands: DDB folds into TBWA, MullenLowe into McCann. FCB is being absorbed by BBDO. The result is three surviving creative networks: TBWA, BBDO, and McCann. The scale is there. What remains to be seen in 2026 is whether operational integration can be completed without further client attrition, and whether the savings estimates hold under execution pressure.

WPP: The Deepest Restructure

WPP’s 2025 full-year revenue fell 5.4% on a like-for-like basis, against a 1% decline the previous year. Headcount dropped from 108,044 at end-2024 to 98,655 by end-2025, a reduction of approximately 9,400 people in twelve months. Ogilvy alone cut around 700 roles (roughly 5% of its 14,000 global staff) in June 2025, with AI integration cited alongside broader restructuring.

The strategic response is Elevate28, announced on 26 February 2026. WPP is reorganising into four divisions: WPP Media, WPP Creative (consolidating VML, Ogilvy, AKQA, and Burson), WPP Production, and WPP Enterprise Solutions. The programme targets £500 million ($676 million) in annual gross cost savings, with total programme cash costs of approximately £400 million phased over two years.

New CEO Cindy Rose, who joined from Microsoft in September 2025 following Mark Read’s departure, was direct at the Elevate28 announcement: “We don’t want to be a holding company any more.” The client losses that accelerated WPP’s decline span multiple sectors. Mars ($1.7 billion media), Coca-Cola ($700 million US media), PayPal, L’Oréal, Starbucks (which moved to Stagwell’s Anomaly in January 2025), plus Uber, Walgreens, Sky, and Yum China are all cited. WPP has guided for a mid-to-high single-digit LFL revenue decline in H1 2026, signalling no short-term stabilisation.

Dentsu: The Write-Down Year

Dentsu’s 2025 financial result is dominated by a single figure: a record net loss of ¥327.6 billion ($2.18 billion), driven by a ¥310.1 billion goodwill impairment on international operations. Net revenue was essentially flat at ¥1,197.5 billion (+0.3%). Dividends have been suspended for both FY2025 and FY2026.

The geographic split is stark. Japan delivered 6.2% organic growth, its eleventh consecutive positive quarter. Outside Japan, the Americas fell 3%, EMEA fell 1.8%, and APAC excluding Japan fell 6.8%. Dentsu cut 2,100 roles in FY2025 and has announced 1,300 further cuts planned for FY2026, a total of approximately 3,400 internationally, representing around 8% of international headcount.

In early 2026, Dentsu explored selling its international operations. No buyers emerged. Shares fell approximately 11% on that news, per Adweek and Campaign Asia reporting. The Japan business remains resilient. The international business remains under structural pressure with no clear resolution announced.

What to Watch in Q1 2026

Q1 2026 earnings have not been released. The key reporting dates are as follows:

• Publicis Q1 2026 revenue: 16 April 2026
• Omnicom / IPG combined Q1 2026 results: April/May 2026 (date to be confirmed)
• WPP Q1 2026 trading update: April/May 2026 (date to be confirmed)
• Dentsu Q1 2026 results: May 2026 (date to be confirmed)

Beyond earnings, the structural questions to track are whether Omnicom’s 4,000 post-merger redundancies are completed on schedule, how WPP’s Elevate28 four-division structure beds in operationally, and whether Dentsu articulates a credible international recovery plan. On the Publicis side, the question is less about survival and more about whether competitors can begin to close the new business gap at all.
