Elevance Health and UnitedHealth earnings will reveal if insurers control rising medical costs.

Elevance Health and UnitedHealth Group, two of the largest U.S. health insurers, are set to report their second-quarter earnings this week. Investors and analysts are watching closely to see if these companies have maintained control over rising medical costs, following a tough 2025 when many insurers had medical loss ratios above 90%. Early 2026 showed improvement, with Elevance's ratio at 86.8% and UnitedHealth's at 83.9%. The reports will provide insight into whether the health insurance sector is stabilizing, especially in profitable Medicare Advantage plans, which offer extra benefits to seniors. Elevance reports on July 15, and UnitedHealth on July 16.
