Strong research. Three brand names competing for the same citation. The engines can't pick a winner.
Citation share for the same research property splits across three brand names — 451 Research, S&P Global, S&P 451 — with no canonical winner. Citation-hygiene problem. Not a research-quality problem. Fixable in 12 months.
Ask ChatGPT about emerging cloud infrastructure vendors. The answer cites "451 Research."
Ask Gemini the same question. The answer cites "S&P Global Market Intelligence."
Ask Perplexity. The answer cites "S&P 451."
Three answers. Three brand strings. One underlying research property. And no engine willing to canonicalize across them, because the source itself has never picked one name and stuck with it.
That is the entire 451 Research story in the 2026 EPR Index. The research is strong. The brand is fractured. The score reflects the fracture, not the research.
451 Research was founded in 2000 in New York by Nick Patience, John Abbott, and Rachel Chalmers. Independent technology research, with particular depth on emerging tech, M&A, infrastructure software, and digital infrastructure. The brand built two decades of equity inside enterprise IT and venture.
S&P Global acquired the firm in 2019. Integration into S&P Global Market Intelligence followed in 2020. The 451 brand was retained — but not exclusively. Reports now publish variously as "451 Research," "S&P Global Market Intelligence," "S&P Global / 451 Research," and occasionally just "S&P Global." Each variant is a separate string in the engines' retrieval indexes. None is canonical. All compete.
Cloud and datacenter infrastructure. AI infrastructure. M&A intelligence — one of the most consistently cited M&A research properties inside the enterprise tech corpus. Voice of the Enterprise, the firm's large-N quantitative survey program covering enterprise IT decision-makers, is one of the most-cited proprietary datasets in the analyst industry. Coverage of private companies and emerging vendors runs deeper than Gartner, Forrester, or IDC — categories where the institutional firms are structurally thin.
The analysts the engines reach for: Nick Patience on AI and machine learning. Liam Eagle on voice of the customer. Owen Rogers on cloud economics. The bench is real. Adam Kansler runs the broader S&P Global Market Intelligence platform within which 451 sits.
Aggregate citation share across the five engines: 59.7. Sixth place in the Index.
If the three brand variants were collapsed into a single canonical entity — "S&P Global Market Intelligence (451 Research)" or any other unified string — the consolidated citation share would meaningfully exceed 70 and the firm would move ahead of HFS. The research justifies a higher score. The naming costs the score.
Pick one canonical name. Force every publication, every analyst byline, every press release, every methodology page, every social handle into that one string. Build schema markup that resolves the alternative strings to the canonical entity. Twelve months of disciplined consistency and the engines consolidate.
This is not strategy. It is hygiene. And it is the single highest-leverage move available to the firm in 2026.
ChatGPT 58%. Claude 55%. Gemini 62%. Perplexity 63%. AI Overviews 60%. The lowest aggregate in the Index — and the most fixable.
