Side-by-side comparison of AI visibility scores, market position, and capabilities

About
UnitedHealth Group is a Minnetonka, Minnesota-based healthcare and insurance conglomerate — publicly traded on the New York Stock Exchange (NYSE: UNH) as the largest healthcare company in the United States by revenue — reporting $400.3 billion in 2024 revenues and operating through two complementary platforms: UnitedHealthcare (health insurance serving 50+ million people) and Optum (health services including OptumHealth care delivery, OptumRx pharmacy benefit management, and OptumInsight technology and analytics). Employing approximately 400,000 people globally across 500+ locations, UnitedHealth Group has been transformed by a turbulent 2024-2025 period: the Change Healthcare ransomware cyberattack (February 2024) disrupted healthcare payments for 190 million Americans; UnitedHealthcare CEO Brian Thompson was murdered in December 2024 in New York City; and CEO Andrew Witty resigned for personal reasons in May 2025, with founder-era CEO Stephen Hemsley returning to lead the company and the 2025 earnings outlook suspended amid higher-than-expected medical costs.
