What the Omnicom-IPG merger could mean for Chicago’s ad scene

FCB Chicago

The recent announcement of Omnicom Group’s $13B acquisition of Interpublic Group (IPG) has sent shockwaves through the global advertising industry, but what could this landmark deal mean for the vibrant advertising community in Chicago?

Both Omnicom and IPG operate notable agencies in the city, and the merger could create ripple effects that reshape the local marketing and advertising landscape.

Chicago’s Key Players

Chicago is home to some of the most influential agencies under both Omnicom and IPG. On Omnicom’s side, Energy BBDO and DDB Chicago are powerhouse creative shops with deep roots in the city’s advertising culture. Energy BBDO has produced iconic campaigns for global brands, while DDB Chicago has a history of high-impact creative work for clients like McDonald’s, State Farm and Anheuser-Busch.

On the IPG side, agencies such as FCB Chicago and Weber Shandwick have long been key players. FCB Chicago, in particular, is known for groundbreaking campaigns like “The Whopper Detour” and its work with brands like Clorox and Michelob Ultra. Meanwhile, Weber Shandwick’s expertise in public relations and integrated communications makes it a go-to for clients navigating today’s complex media landscape.

With these heavyweights potentially combining forces, Chicago’s advertising ecosystem stands to undergo significant changes.

Opportunities for Chicago Agencies

The merger promises to bring together complementary strengths from Omnicom and IPG, potentially giving Chicago agencies access to a wider array of resources and technologies. For agencies like Energy BBDO, DDB Chicago, and FCB Chicago, this could mean greater collaboration across disciplines, expanded client opportunities, and new tools for data-driven campaigns.

Additionally, the merger may bolster Chicago’s position as a key hub for integrated marketing solutions. By pooling expertise across creative, media, and technology, the combined company could attract more national and global brands to set up shop or expand their presence in the Windy City.

Chicago’s unique mix of Midwestern sensibility and global perspective could make it a testing ground for the new Omnicom’s ambitious strategies.

Challenges Ahead

While the merger brings exciting opportunities, it also raises concerns about consolidation and competition. For one, smaller independent shops in Chicago may find it harder to compete with the combined scale and capabilities of Omnicom and IPG shops. The merger could further tilt the playing field in favor of large conglomerates, limiting options for clients seeking more boutique or specialized services.

Internally, agencies may face redundancies or cultural clashes as the two organizations integrate. Will FCB Chicago retain its identity within the new Omnicom structure? How will DDB Chicago and Energy BBDO collaborate—or compete—under the same umbrella? These questions remain unanswered, but their outcomes will shape the city’s advertising landscape.

Chicago’s Broader Role

Chicago’s advertising community thrives on its diversity of talent, from creatives to strategists to tech innovators. This merger could amplify Chicago’s role as a key player in the advertising industry’s future. If executed well, the deal could position the city as a central hub for the combined company’s North American operations, leveraging its reputation for producing iconic campaigns and fostering collaboration.

However, if the integration leads to downsizing or the loss of agency independence, it could dampen the city’s creative vibrancy. Clients drawn to Chicago’s unique blend of big ideas and authentic storytelling might look elsewhere if the merger stifles that spark.

The Waiting Game

For now, the full impact of the Omnicom-IPG merger on Chicago’s advertising scene remains speculative. The deal is set to close in the second half of 2025, pending shareholder and regulatory approvals, giving agencies time to prepare for the changes ahead.

Chicago’s advertising community will be watching closely to see whether the merger enhances its status as a creative powerhouse—or challenges its ability to stand out in an increasingly consolidated industry.

In a city known for its resilience and ingenuity, one thing is certain: Chicago’s advertising scene will adapt, evolve, and continue to make its mark in the ever-changing world of marketing.
