Betterment was named in 69.4% of 186 AI answers about robo-advisors, the highest appearance rate 5WPR measured across Perplexity, ChatGPT, Gemini and Claude on September 6, 2026. Fidelity was named less often, at 66.1%, but its own website supplied the cited evidence in 26.3% of answers with retrieval evidence, more than double Betterment's 12.4% rate. The two brands are winning two different contests.
How Often Does Each Robo-Advisor Get Named By AI?
Betterment led the 5WPR Robo-Advisors & Retail Investing AI Visibility Index 2026 at a 69.4% appearance rate across 186 returned answers, with a 95% confidence interval of 62.4% to 75.5%. Vanguard followed at 66.7% and Fidelity at 66.1%, both with intervals that overlap Betterment's. Wealthfront reached 62.4% and SoFi 51.6%. The study ran 24 prompts three times each across four engines, attempting 288 answers and returning 186.
Why it works: Wilson score intervals quantify sampling uncertainty at a fixed sample size, so two brands whose intervals overlap cannot be ranked against each other with confidence from this data alone, per the study's own methodology (5WPR, September 6, 2026). A brand team that reports "we beat Vanguard" on this data is making a claim the sample cannot support.
Does Getting Named Mean Getting Cited?
No. Fidelity had the highest owned-domain citation rate among the leading brands at 26.3% of 186 answers with retrieval evidence, ahead of Wealthfront at 17.7%, Vanguard at 14.0%, Charles Schwab at 13.4% and Betterment at 12.4%. Robinhood, SigFig, Webull and Public each had a 0% owned-domain citation rate despite appearing in returned answers.
Why it works: An AI engine can name a brand from training data or a competitor's page and still never quote the brand's own site as evidence. 5WPR's September 6, 2026 measurement counts a citation only when the engine returned a retrieval receipt pointing at the brand's own domain, so a 0% rate means the brand supplied none of its own supporting evidence in the answers where it appeared.
Why Do Perplexity And ChatGPT Disagree With Gemini And Claude?
ChatGPT named Vanguard in 97.8% of its 46 returned answers, while Claude named Vanguard in only 30.4% of its own 46. Perplexity named Fidelity in 95.8% of its 48 answers, compared with 39.1% for Gemini. Charles Schwab appeared in 91.3% of ChatGPT answers and 21.7% of Gemini answers.

Why it works: Each engine pairs a different underlying model with a different retrieval tool, so a brand's appearance rate reflects that engine's specific search and ranking behavior as much as the brand's own visibility (5WPR, September 6, 2026). A brand team measuring only one engine can reasonably conclude it dominates the category or is absent from it, and be wrong either way.
Which Publishers Are Winning The Citations Robo-Advisors Want?
Forbes appeared as a cited source in 72.6% of the 186 answers with retrieval evidence, ahead of NerdWallet at 48.9% and CNBC at 35.5%. Fidelity.com was the most-cited brand-owned domain among the sources listed, appearing in 25.8% of those answers, ahead of Wealthfront.com at 15.1% and Betterment.com at 12.4%.
Why it works: Financial-advice engines lean on publishers with an established editorial review process for regulated-product comparisons, so a brand's own product pages compete directly against Forbes, NerdWallet and CNBC for the same citation slot rather than filling an empty one (5WPR, September 6, 2026).
What Should A Robo-Advisor Fix First?
Robinhood, SigFig, Webull and Public should publish direct, sourceable explanations of how their automated investing products work, since each had a 0% owned-domain citation rate across 186 evidence-backed answers. Charles Schwab should investigate the 91.3%-to-21.7% gap between its ChatGPT and Gemini appearance rates before assuming its visibility is stable. SoFi and M1 Finance, at 5.9% and 4.8% owned-domain citation rates, should rebuild their tax-loss-harvesting and account-minimum pages as direct, citable answers rather than marketing copy.
Conclusion
Appearance and citation measure two different outcomes, and this data shows a robo-advisor can lead one while trailing the other. Financial brands that want their own site quoted, not just their name mentioned, need pages built for retrieval and a measurement plan that checks all four engines separately. 5W runs AI Search (GEO) programs for brands across consumer, B2B, financial services, healthcare, and technology, building the machine-readable footprint that gets brands cited, not just ranked.
