aetna vs Humana

About

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.
