Marathon Oil Employees: Expect Rising Health Insurance Costs in 2026

Healthcare Provider Update: Healthcare Provider for Marathon Oil: Marathon Oil utilizes various healthcare providers for its employee health insurance plans, including major national insurers such as UnitedHealthcare, Anthem Blue Cross Blue Shield, and Cigna. These partnerships typically aim to deliver comprehensive health coverage to employees, taking into account various healthcare needs and preferences. Potential Healthcare Cost Increases in 2026: As we approach 2026, employees of Marathon Oil may face significantly higher healthcare costs due to anticipated sharp increases in Affordable Care Act (ACA) premiums. Projections indicate that up to 92% of ACA policyholders could see their monthly premiums rise by over 75%, largely attributed to the expiration of enhanced federal subsidies. Coupled with record rate hikes from insurers-some exceeding 60%-these factors are creating a perfect storm for increased healthcare expenses, impacting financial planning for many employees considering retirement or changes in coverage. Without proactive strategies, employees may find themselves navigating a challenging healthcare landscape. Click here to learn more

'With health care expenses climbing faster than wages, Marathon Oil employees should proactively evaluate their coverage options to help protect their long-term financial well-being,' says Tyson Mavar, a representative of The Retirement Group, a division of Wealth Enhancement.

In this article, we will discuss:

1. Why health insurance costs may rise in 2026.

2. What changes could impact Affordable Care Act and employer plans.

3. How to review your options during open enrollment.

Health insurance expenses may soon climb even higher for millions of households, including those of Marathon Oil 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 Marathon Oil. 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.
