Marathon Oil Workers Prepare for Sharp Health Care Cost Increases 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

In this article, we will discuss:

1. Why health insurance premiums may rise in 2026.

2. How these changes could affect Marathon Oil employees and retirees.

3. Steps to help prepare for higher health care costs.

Millions of Americans, including employees at Marathon Oil, are learning that health insurance premiums could increase significantly in 2026. Depending on the state, income, and whether federal subsidies are offered, monthly premiums for many people may jump by double-digit percentages. ¹

Insurers are sending out letters to Affordable Care Act (ACA) marketplace plans nationwide, detailing significant rate increases that could impact Marathon Oil households who rely on supplemental or early retirement coverage. In many cases, people’s monthly premiums will go up by hundreds of dollars in the upcoming year. ²

Health policy researchers have collected new data suggesting average increases for marketplace plans could range from 10% to more than 20%. ¹  Many subscribers, including Marathon Oil retirees using marketplace plans, may see payments more than quadruple if expanded government subsidies disappear. ¹

Those purchasing insurance on the exchanges are not the only ones facing higher costs. Employer-sponsored plans used by many Marathon Oil families are also facing rising expenses as medical spending rebounds. In 2026, businesses anticipate an average cost increase of approximately 9%. ³

Reasons for Increasing Premiums

The main drivers behind premium hikes, according to insurers, include an aging population, rising medical costs, and increased health care usage post-pandemic—trends likely to impact Marathon Oil retirees.

In addition, unless Congress intervenes, the expanded ACA subsidies implemented during the pandemic are scheduled to expire after 2025, a potential concern for former Marathon Oil workers who rely on this support before Medicare eligibility. Without these subsidies, many middle-class families could see costs surge immediately.

More than 90% of ACA subscribers receive some government assistance with their premiums, ⁴  and analysts warn that if the expanded subsidies end, millions—including some who retired from Marathon Oil early—could lose coverage entirely by 2027. ⁴  

The Individual Effect

Every statistic reflects a personal challenge impacting families. Small business owners, independent contractors, and early retirees are already reporting premium increases from $250 to $700 per month in several states. ⁵

Some households losing subsidies could face monthly premiums of $2,000 or more ⁴ —far above the $300–$400 range typical today—creating greater strain for Marathon Oil retirees trying to manage health care expenses.

Those living with chronic conditions face even harder decisions, since routine care and medications remain essential.

Getting Ready for 2026

Advisors recommend reviewing health plan options thoroughly during upcoming enrollment seasons, especially for those nearing retirement. This includes checking subsidy eligibility, comparing multiple coverage options, and evaluating whether a spousal or employer-sponsored plan could offer better value.

Professionals approaching retirement may want to consider tax-efficient health care savings tools like Health Savings Accounts (HSAs) and Flexible Spending Accounts (FSAs) to help manage higher costs. It is also important to account for health care inflation when forecasting post-employment income.

A Monetary Urge to Act

Rising health care expenses can disrupt long-term goals for individuals and families, including those with many years of service at Marathon Oil. Medical coverage decisions should tie to retirement income strategies, tax planning, and asset preservation.
