Nationwide Pet and MetLife Pet — two of the largest insurance companies on Earth — capture a combined 3.9% of pet insurance citations inside ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews. Trupanion alone captures 28.4%. A company with a fraction of their institutional resources owns 7× more of the answer layer than both legacy giants combined.
The pet insurance buyer no longer compares plans on Google first. Increasingly, they ask an AI engine. And the AI engines do not recommend Nationwide or MetLife. They recommend Trupanion, Lemonade, and Healthy Paws — the brands that built the content infrastructure the engines retrieve from.
This is the central finding of the 5W Pet Insurance AI Visibility Index 2026, the first study to measure which pet insurance brands dominate AI-generated recommendations across all five major engines — and which have institutional scale but zero AI presence.
