May 22, 2026
A new benchmark from 5W shows that Andreessen Horowitz is the only venture firm whose website is consistently cited by major AI assistants, ranking ahead of Forbes, PitchBook, and Bloomberg.

5WPR has published its Venture Capital AI Visibility Index 2026, which finds that Andreessen Horowitz (a16z) is the only venture firm whose website is reliably cited by major AI engines. The findings were announced in a press release.

The study analyzed 28,400 prompts across ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews between January and May 2026. It covered 60 venture firms and 100 named partners. a16z achieved a 21.4 percent citation share, followed by Sequoia Capital with 17.8 percent and Y Combinator with 15.9 percent. Together, these three firms accounted for 55.1 percent of all venture capital citations.

a16z.com appeared in 7.1 percent of retrieved responses, making it the only venture firm domain among the top ten cited sources. It ranked ahead of Forbes, PitchBook, Bloomberg, and The Wall Street Journal. No other firm-owned domain placed within the top 25.

The report also found that fund size does not predict AI visibility. Insight Partners, with roughly 80 billion dollars in assets under management, recorded a 1.6 percent citation share, while Tiger Global registered 1.3 percent. The Index noted that consistent earned media and owned content publishing correlated more strongly with AI visibility than fund size.
