NEW YORK — Why don’t credit union card offerings appear more often when consumers search for the best offers? In large part, because artificial intelligence platforms are relying far more on financial publishers than credit card issuers themselves when recommending credit cards to consumers, according to a new analysis released by communications firm 5W, which finds credit unions nowhere to be found.
The firm’s Credit Cards AI Visibility Index 2026 examined 4,200 consumer prompts submitted between Jan. 6 and April 30 across five major AI platforms: ChatGPT, Claude, Perplexity, Gemini and Google AI Overviews.
According to 5W, the study is the first benchmark designed to measure which credit cards and issuers are most frequently cited by AI platforms when consumers seek recommendations.
The analysis found that AI-generated recommendations are dominated by a handful of independent financial publishers rather than issuer-owned websites, creating what 5W described as a disconnect between how issuers spend their marketing dollars and where AI systems source information.
Key Findings
According to 5W:
- Three publisher websites—The Points Guy, NerdWallet and Bankrate—accounted for more than 62% of all citations across the study.
- Issuer-owned websites, including those of Chase, American Express, Capital One, Citi and Discover, accounted for fewer than 6% of citations.
- Credit cards carrying annual fees exceeding $400 were cited 5.7 times more often than no-fee cards in general “best credit card” searches.
- Reddit communities, including r/CreditCards, r/churning and r/awardtravel, appeared in 38% of advanced travel rewards queries but only 4% of entry-level credit card searches.
- Co-branded airline and hotel credit cards lost citation share to general-purpose rewards cards across nearly every search category analyzed.
Most Frequently Cited Cards
The five most-cited credit cards in AI-generated responses were:
- Chase Sapphire Reserve
- American Express Platinum
- Capital One Venture X
- Chase Sapphire Preferred
- American Express Gold
According to 5W, the complete index ranks 25 credit cards across four citation tiers, identifies six major issuers that underperformed in AI visibility—including Bank of America and U.S. Bank—and outlines structural trends influencing how AI systems generate recommendations.
Marketing Implications
The report comes as U.S. credit card issuers collectively spend an estimated $20 billion annually on direct mail, digital advertising and brand marketing campaigns.
Despite that investment, 5W said AI platforms frequently rely on affiliate publisher content and online discussion forums rather than issuer-produced information when answering consumer questions about credit cards.
“When a consumer asks ChatGPT, ‘What is the best credit card for me?,’ the answer is being supplied by three publishers,” Ronn Torossian, founder of 5W, said in a statement. “Issuers can spend their way around that for a while. They can’t spend their way through it.”
Five Structural Trends
According to the analysis, five structural trends are reshaping AI-generated credit card recommendations, including what 5W described as a 13-week citation decay cycle for welcome bonus offers, the growing influence of Reddit in high-intent research and the underrepresentation of no-fee credit cards relative to consumer demand.
