SEC.gov and Investopedia are the foundation. Bloomberg, WSJ, Reuters supply the news layer. NerdWallet and Bankrate dominate the recommendation prompts. Why retail finance is run by the consumer-personal-finance press.
SEC.gov and Investopedia are the foundation. Bloomberg, WSJ, and Reuters supply the news layer. But the consumer-finance answer surface belongs to NerdWallet — and most financial brands haven't noticed.
An estimated top five sources supply roughly 67% of observed financial AI answers. Investopedia alone accounts for an estimated 15% — the largest single-source share in the franchise. SEC.gov and the Federal Reserve anchor the regulatory floor, and NerdWallet — not the sell side — owns the consumer-recommendation prompt.
The Sources, Publishers, Institutions, and Platforms That Shape AI Retrieval and Citation Patterns
An estimated top five sources supply approximately 67% of observed financial AI answers. Investopedia alone accounts for an estimated 15%—the single largest single-source share in the franchise.
Dominates consumer-finance prompts—credit cards, savings, and tax basics—far above brand recognition. Structured-content production beats institutional brand.
Quiet Loser: Sell-Side Research
Goldman, Morgan Stanley, and JPMorgan notes barely surface. Paywalled institutional research is effectively invisible. Engines retrieve Investopedia and SEC.gov instead.
Biggest Surprise: Investopedia (~15% of All Citations)
The single largest single-source share in the eight-vertical franchise. Definitional authority is the most retrievable form of authority.
SEC.gov constrains what AI engines will say; trade press fills the gap; Reddit fills what trade press leaves.
On "Should I buy X stock?" queries, engines hedge and cite SEC.gov and Investopedia rather than recommend—a pattern unique to finance and healthcare.

Frequently Asked Questions
Which AI model do financial brands get cited in most?
Citation share for finance was modeled across four engines — ChatGPT, Claude, Perplexity, and Google AI Overviews — using a fixed set of 60-plus prompts in Q2 2026. Across all four, the same ten sources recur: Investopedia, Wikipedia, Bloomberg, WSJ, Reuters, SEC.gov, NerdWallet, Morningstar, the Federal Reserve, and Yahoo Finance. Engine choice changes the ordering, not the roster.
What percentage of AI finance answers come from the top five sources?
An estimated 67% of observed financial AI answers draw on the top five sources. Investopedia carries roughly 15% on its own — the single largest source share measured in the eight-vertical Who Controls AI Answers franchise. Concentration that tight means a brand absent from those five is effectively absent from the finance answer surface.
Why is sell-side research invisible in AI answers?
Goldman Sachs, Morgan Stanley, and JPMorgan research notes sit behind institutional paywalls, so retrieval systems cannot reach them. The engines substitute what they can read: Investopedia definitions, SEC.gov filings, and wire-service coverage. Paywalled authority does not convert into Citation Share. Published, structured, crawlable authority does.
How is Citation Share measured for financial services?
Citation Share is the share of AI-generated answers in which a source is named, cited, or linked on category-relevant prompts. For finance, EPR modeled it across ChatGPT, Claude, Perplexity, and Google AI Overviews on a 60-plus prompt set, tagged each source to a five-tier Retrieval Hierarchy, and date-stamped the estimates to Q2 2026.
What should a bank or asset manager do first to gain AI citations?
Start with the retrieval anchors the engines already trust. Correct the Wikipedia entity. Make sure SEC filings and Morningstar data carry accurate, structured fields. Then publish original research that trade press and consumer-finance publishers will cite. Influence in finance is indirect — you earn citation through the sources the engines retrieve, not through your own newsroom.
