Which sources do AI engines cite most for finance?

Investopedia, Wikipedia, Bloomberg, WSJ, Reuters, SEC.gov, NerdWallet, Morningstar, the Federal Reserve, and Yahoo Finance. Investopedia alone accounts for an estimated 15%.

Why does NerdWallet dominate consumer-finance AI answers?

Structured, sourced, schema-tagged content at industrial scale across credit cards, savings products, and tax basics. Content structure beats brand recognition.

Are AI engines cautious about investment advice?

Yes. On stock-specific prompts the engines hedge and cite SEC.gov, Investopedia, and trade press rather than recommend. Reddit and finance media fill the gap.

How is SEC.gov cited in financial AI answers?

SEC.gov is the primary-source authority for filings, enforcement, ETF approvals, and registrations. Citation share rises sharply on regulatory prompts.

Do Bloomberg, WSJ, and Reuters get cited equally?

Close, with differences by prompt class. Bloomberg leads on company analysis. WSJ leads on US business news. Reuters leads on global markets and wire-service prompts.

How can asset managers increase their AI citation share?

Influence is indirect. Produce structured research that earns coverage. Maintain Wikipedia accuracy. Surface in Morningstar and SEC data structures.

Editorial Tensions§ 02

Hidden Winner

NerdWallet

Dominates consumer-finance prompts — credit cards, savings, tax 101 — far above brand recognition. Structured-content production beats institutional brand.

Quiet Loser

Sell-side research (Goldman, Morgan Stanley notes)

Paywalled institutional research barely surfaces. Engines retrieve Investopedia and SEC.gov instead.

Biggest Surprise

Investopedia ~15% of all citations

The single largest single-source share in the eight-vertical slate. Definitional authority is the most retrievable form of authority.

The Contested Zone§ 03

Stock-specific prompts · investment advice · crypto-finance overlap. SEC.gov constrains what can be said; trade press fills the gap; Reddit fills what trade press leaves.

News Peg§ 04

AI-driven retail investment research has gone mainstream. The citation map decides the answer to "should I buy."
