Largest US health insurer with $372B revenue insuring 50M Americans; UnitedHealthcare insurance plus Optum pharmacy and care delivery navigating CEO murder, cyberattack, and claims denial scrutiny.
UnitedHealth Group is the largest US health insurance company and one of the largest companies in the world by revenue, operating through two primary business segments: UnitedHealthcare (health insurance for individuals, employers, Medicare Advantage, and Medicaid) and Optum (health services, pharmacy benefits management, and care delivery). Listed on NYSE (NYSE: UNH) and headquartered in Minnetonka, Minnesota, UnitedHealth generates approximately $372 billion in annual revenue and insures approximately 50 million Americans.\n\nUnitedHealthcare provides employer-sponsored group health insurance (the largest business segment), individual marketplace plans, Medicare Advantage plans (one of the largest MA insurers), and Medicaid managed care plans across all 50 states. Optum provides pharmacy benefits management (OptumRx, managing prescription benefits for insured members), care delivery (Optum Health operates clinic networks and physician groups with over 90,000 physicians), and health IT services (OptumInsight provides analytics and technology to health systems and payers).\n\nIn 2025, UnitedHealth Group faces extraordinary challenges following the December 2024 murder of CEO Brian Thompson and the subsequent investigation of its claims denial practices, which drew intense public and regulatory scrutiny of insurance industry practices. The company also manages the aftermath of the February 2024 Change Healthcare cyberattack (Change Healthcare is an Optum subsidiary) — one of the largest healthcare data breaches in US history, affecting approximately 190 million Americans and causing multi-billion dollar financial losses. UnitedHealth competes with Elevance Health (Anthem), CVS Health (Aetna), and Cigna for health insurance and pharmacy benefits market share. The 2025 strategy involves managing regulatory pressure, restoring Change Healthcare operations, and continuing Optum's vertical integration strategy.
$115.8B revenue 2024 (+12.7% YoY), 5.7M Medicare Advantage members, CenterWell Senior Primary Care expansion, #3 US health insurer
Humana is one of the largest health insurance and healthcare services companies in the United States, founded in 1961 and headquartered in Louisville, Kentucky. Originally a nursing home operator, Humana pivoted to managed care in the 1980s and has since become a dominant force in Medicare Advantage — the government-funded private insurance alternative for Americans over 65. The company's mission centers on helping people achieve lifelong well-being by making healthcare simpler, more accessible, and more proactive.\n\nHumana's core businesses include Medicare Advantage plans, Medicaid managed care, military health services through its TRICARE contract, and a rapidly expanding healthcare delivery arm through CenterWell — which operates senior-focused primary care clinics, home health services, and specialty pharmacy. With 5.7 million Medicare Advantage members, Humana is the #3 US health insurer by total enrollment and the #2 Medicare Advantage carrier in the country. The CenterWell strategy represents a long-term shift from pure insurance toward vertically integrated care delivery.\n\nHumana posted $115.8 billion in revenue for 2024, a 12.7% increase year-over-year, driven by sustained demand growth as the US population ages into Medicare eligibility. The company faces margin pressure from elevated medical costs in Medicare Advantage — an industry-wide challenge through 2024–2025 — but its vertically integrated care model and concentrated scale in the senior market give it structural competitive advantages that differentiate it from pure-play insurance carriers.
