By EPR Editorial Team · Originally published June 9, 2026.
The inaugural P&C Insurance Citation Share Index 2026 measures which property-and-casualty insurers ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews actually cite when asked about auto insurance, home insurance, claim service, and rates. State Farm owns scale and the agent network. GEICO owns price-leader retrieval. Progressive owns digital-direct. Allstate owns claim service. Liberty Mutual owns customized-coverage retrieval.
Why P&C insurance Citation Share matters in 2026
The auto-and-home-insurance shopping decision is one of the highest-volume consumer AI prompts. P&C insurers compete inside a citation graph the carriers do not control. J.D. Power, AM Best, NAIC complaint indexes, Consumer Reports, NerdWallet, Bankrate, The Zebra, Insurify, and r/Insurance are the sources the engines retrieve. Full source-layer analysis in Who Controls AI Answers in Insurance.
