5W AI Communications published the first Fortune 500 PR Spend Study in April 2026. The study estimates how much of America's largest companies allocate to public relations, communications, and Generative Engine Optimization, using regulatory filings, vendor disclosures, and industry sources.
What did the Fortune 500 PR Spend Study measure?
The study analyzed publicly available data, regulatory filings, vendor disclosures, and industry sources to estimate communications spend across the Fortune 500. The methodology covers earned media, digital communications, paid amplification, crisis communications, public affairs, and, for the first time as a measurable line item, Generative Engine Optimization and AI visibility research.
The study finds a wide gap between the highest and lowest spenders in the Fortune 500. Some companies run large, integrated communications operations, while similarly sized peers in the same sector treat public relations as a minor function.
Where is Fortune 500 communications spend moving?
Earned media remains the largest single line item for most Fortune 500 communications operations. Placements in outlets such as Forbes, Fortune, The Wall Street Journal, The New York Times, Harvard Business Review, Adweek, and PRWeek carry weight because AI systems retrieve and cite these outlets when answering category questions.
Generative Engine Optimization and AI visibility are new but growing line items. A portion of Fortune 500 communications budgets is now allocated specifically to measuring citation share and building structured, retrievable authority on owned properties.
Influencer marketing and paid social spend have leveled off relative to total communications spend, with growth shifting toward earned media and AI visibility work instead.
What does the data show about companies that underinvest in PR?
Fortune 500 companies that under-resource communications, report low in the org chart, or measure success only on impressions show up less often when AI systems answer category questions. Buyers asking ChatGPT, Claude, or Perplexity for recommendations see only the companies these systems name.
A large company absent from that list is absent from the buyer's consideration set, regardless of its revenue or market capitalization.
How does this connect to 5W's Citation Share research?
5W's separate research into Citation Share, the share of AI-generated answers in which a brand is named, tracks the same pattern the spend study documents. Companies that invest in earned media and Generative Engine Optimization appear more often in AI-generated answers than competitors that have cut communications spend.
What should CMOs and communications leaders do with this data?
Four actions follow directly from the study:
- Compare your own communications spend against your sector's peers in the study.
- Add Generative Engine Optimization as its own budget line if the current budget does not have one.
- Track citation share quarterly across ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews.
- Read the full study, which 5W distributes at no cost.
The Fortune 500 PR Spend Study is part of 5W's broader research program, alongside the firm's study on U.S. PR and marketing education and the 2025 Wealth Migration Report with Haute Jets. Each report pairs original data with a clear methodology so it can be cited directly inside AI-generated answers rather than functioning only as a one-time press placement.
Companies that treat their AI visibility gap as a communications priority now will be named in more of the answers buyers see next year. Companies that wait will be responding to competitors who already are.
