Provoke Media Calculates Size Of Global PR Agency Business At $50 Billion

Accurately estimating the size of the global PR agency business is extremely difficult. Other estimates of the industry's size vary dramatically, from $20 billion to $105 billion The 400 firms for which we were able to determine 2025 revenues generated $18.3 billion between them-and employed around 82,000 people Estimates suggest 150,000 agency businesses globally, employing 395,000 people A simple extrapolation says the business could be as big as $82 billion-but we think $50 billion is a more realistic estimate

Calculating the size of the global public relations agency business is notoriously difficult.

To begin with, there's no globally accepted definition of just what the term“public relations” includes. For us, it clearly includes public affairs, investor relations, employee communications, corporate communications, and any consumer marketing activity that centers around earned, shared or owned channels-as well as most social media and influencer marketing. So any agency focused on any or all of the above would meet our definition of a“PR agency.”

Then there's the problem that remarkably few public relations agencies operate under a corporate structure that requires them to report revenues. Many publicly-traded holding companies hide their agencies' revenues behind a bizarre but now sadly standard interpretation of Sarbanes-Oxley rules. Many privately-held firms eschew transparency and remain disappointingly opaque about what they do and for whom-as well as how much money they make.

Beyond that, there are vastly different cultures in different markets around the world, as well as significant variations in the quality of coverage in those markets. So while the PR agency business in the US and the UK is relatively well documented, there is less robust coverage in emerging markets in particular.

And finally, public relations is a“long tail” business. With low barriers to entry, there are literally hundreds of thousands of small firms-some of them with one or two employees-doing PR work for at most a handful of clients. These firms are almost impossible to identify, never mind estimating their headcount and revenues.

So the agencies on our PRovoke Media 300 Global Ranking are a small fraction of all the public relations firms out there, and their combined $18.3 million in fee income only a starting point for calculations of the industry's size.

More than $100 Billion or Less Than $20 Billion?

These difficulties are reflected in a series of reports that provide wildly different estimates of the agency business.

Mordor Intelligence, which employs teams of experts to produce intelligence reports across more than 100 industry segments, calculates the size of the PR business at around $105 billion -although it appears that this estimate includes in-house PR teams as well as agencies.

IBIS World, meanwhile, says the market size of the global public relations agency business i s $75.1 billion in 2026 .

And a Statista report published in December of last year, meanwhile, says the estimated size of the PR market worldwide “slightly decreased in 2023 after peaking at $20 billion the year prior.”

The details of these reports are available to subscribers only and the methodologies employed are not always clear-making it difficult to assess the accuracy of their very different estimates. For that reason, I am not going to claim that PRovoke Media's estimate is more accurate than any of them-but the method by which we arrived at our estimate is outlined here.

How We Got to $50 Billion

The information gathered for our PRovoke Media 300 Global Ranking of the world's largest public relations agencies is the starting point for our own calculation. In compiling this list we have been able to verify revenue numbers for around 200 firms, and information from other sources has allowed us to estimate revenues for another 200-with revenues for these 400 agencies totaling more than $18.3 billion.

But the IBIS report references above-which I personally believe to be the most accurate estimate available-has identified more than 150,000 agency businesses globally, employing 395,000 people (which would give the average firm fewer than 3 employees, which makes sense given the“long tail” issue.

The agencies for which we have headcount information employ about 82,000 people between them-which is to say just 20% or so of the agency employees estimated in the IBIS report-at an average revenue per head of around $205,000.

If that revenue per head held across the 313,000 PR agency employees not included in our ranking, they would generate an additional $64 billion-meaning that the global PR industry would be a $82 billion business.

But we think that's unlikely. While there are some very significant businesses absent from our ranking-corporate and public affairs firms that generate substantial revenue at a high per capita level-it seems likely that on average these 150,000 mostly micro-sized agencies operate in smaller markets where fees and salaries are lower.

Acknowledging this, and preferring to keep our estimates conservative, we would prefer to assume that the revenue per head for these non-reporting firms is around half that of the leading agencies on our list, meaning that the 313,000 people not included in our ranking more likely generate about $32 billion.

That gives us an overall PR agency business of slightly more than $50 billion-up between 5 and 6% on last year-a number that makes sense in terms of the growth we measured among the leading firms.
