In this article, we will discuss:

Why health insurance costs may rise in 2026.
What changes could impact Affordable Care Act and employer plans.
How to review your options during open enrollment.

Health insurance expenses may soon climb even higher for millions of households, including those of Ameren employees. Some people have even received advance notice of increases through 2026, adding to concerns that affordable insurance options are becoming more limited.

If you are one of the approximately 24 million Americans enrolled in an ACA marketplace plan, ¹ be aware that significant shifts could occur soon. If enhanced ACA premium tax credits expire after 2025, the average family premium could rise 114%, jumping from $888 in 2025 to $1,904 in 2026. ¹

Rising expenses are also impacting those covered through employer plans, including employees at Ameren. Surveys indicate that employer-sponsored health insurance costs are estimated to go up by 6% to 9% in 2026—the biggest increase in more than 15 years. ² As companies continue shifting more of these expenses to workers, payroll deductions and out-of-pocket costs are on the rise. Health care cost growth is even outpacing wage growth, ³ adding pressure on family budgets.

Why Are Prices Increasing?

Many factors contribute to the upward trend, ³ including:

- A surge in medical visits delayed during the pandemic
- The growing number of older Americans requiring ongoing care
- Continued high incidence of chronic illnesses such as diabetes and heart disease
- Shortages and rising labor costs in the health care workforce
- Higher demand for services combined with fewer workers
Competitive differences across regions also influence costs—some markets have many insurance options, while others have only one or two participating carriers.

What to Do During Open Enrollment

Review your current health care usage. If you typically use fewer services, a high-deductible plan paired with a Health Savings Account might lower monthly premiums and offer certain tax advantages.
Plan ahead for anticipated medical needs. If you expect more care next year, a plan with higher monthly payments but lower deductibles may help spread costs more evenly.
Explore additional coverage options. Depending on eligibility, Medicaid, CHIP, or catastrophic plans may help if employer or marketplace premiums increase sharply.
Stay flexible while enrollment is open. You can modify your plan through the end of open enrollment if your situation or subsidy rules change.
