Mainly because health care itself is expensive. Premiums reflect the underlying cost of claims, and those costs are pushed up by provider and insurer consolidation, the rising prevalence of chronic disease, expensive new drugs and technology, and the fact that third-party payment mutes normal price competition.
Cost Drivers
Premiums rise with the underlying cost of care. These FAQs explain what drives health insurance costs, why premiums increase even when coverage doesn’t change, and the 2026 trends.
What’s happening to health insurance costs for 2026?
Costs are rising sharply. Employer health plan costs are projected up roughly 7–9% for 2026, and ACA Marketplace premiums rose more after enhanced subsidies expired, in some states 30% or more. The main drivers are medical inflation, specialty and GLP-1 drug costs, and the subsidy change.
Why did my premium go up even though my coverage didn’t change?
Premiums reflect the expected cost of claims, not whether your specific benefits changed. They rise each year with medical inflation, drug prices, and your group’s own claims experience and changing demographics, because the carrier reprices annually to cover expected costs.
