'With ACA marketplace premiums expected to climb in 2026, DTE Energy employees should compare employer and marketplace options early, estimate net costs under both current and lapsed subsidy scenarios, and coordinate with HR and a qualified tax professional to align coverage with their budget.' — Michael Corgiat, a representative of The Retirement Group, a division of Wealth Enhancement.

• In this article we will discuss:

  1. The expected premium increases for ACA marketplace plans in 2026 and their potential impact on DTE Energy employees and retirees.

  2. The major national insurers and states with the largest requested rate hikes.

  3. The primary economic, legislative, and industry factors driving these increases.

  In 2026, health insurance rates for plans purchased through the Affordable Care Act (ACA) marketplace are  expected  to surge, with several insurers requesting increases exceeding 60%. ¹  For DTE Energy employees and retirees using ACA coverage, this could mean a substantial rise in health care costs. State insurance filings and industry publications point to higher medical expenses, the potential end of enhanced federal premium subsidies, and significant rate-hike proposals from major insurers as key drivers of the increase.

  According to KFF’s analyses, the vast majority of marketplace enrollees receive premium tax credits, and if the enhanced credits expire after 2026, average out-of-pocket premium payments for subsidized enrollees could rise by more than 75% in 2026. ¹  As of January 2026, 24.2 million people selected 2026 marketplace coverage, ²  and about 93% of marketplace enrollees rely on premium tax credits. ³  KFF also reports that requested premium increases for 2026 are the largest in years, with most proposals falling between roughly 12% and 27% and a median of 18% across reviewed filings. ⁴

  Top 10 States With the Largest Requested Premium Increases for 2026:

  • New York:  UnitedHealthcare requesting up to  +66.4%  (individual market).

  • Arkansas:  QualChoice  +54.4% , Ambetter (Celtic)  +42.5% , statewide average  +36.1% .

  • Colorado:  Western Slope  ~+38.8% ; statewide average  +28.4% . Rocky Mountain HMO  +36.4% , Cigna  +29.4% , Anthem  +33.6% , Kaiser  +15.3% .

  • Florida:  Molina  ~+41% , Florida Blue  +27% , Centene Venture  +18.73%

  • Maine:  Anthem (revised)  +24.8% ; statewide weighted average  +25.9% .

  • Washington:   14  insurers; requested average  +21.2% .

  • Vermont:  BCBS Vermont  +23.3% . 

  • Maryland:  Requested statewide average  +17.1%  (individual market).

  • Illinois:  BCBS Illinois  +27% . 

  • Texas:  BCBS Texas  +21% .

Major National Insurers and Their 2026 Requests:

• UnitedHealthcare (UnitedHealth Group):  Up to  +66.4%  in New York.

• Elevance Health (Anthem BCBS):   +33.6%  in Colorado;  +24.8%  in Maine. 

• Kaiser Permanente:   +15.3%  in Colorado (individual market). 

• Centene Corporation (Ambetter/Celtic):   +42.5%  in Arkansas;  +18.73%  in Florida.

• Cigna Healthcare:   +29.4%  in Colorado. 

• Molina Healthcare:   ~41%  in Florida.

• HCSC (BCBS IL, TX):   +27%  in Illinois;  +21%  in Texas. 

• GuideWell (Florida Blue):   +27%  in Florida. 

• CareFirst BlueCross BlueShield:  Maryland requested statewide average  +17.1% .

• CVS Health/Aetna:  Withdrawing ACA marketplace plans in  17 states  in 2026, affecting  ~1 million  members.

Key Factors Driving the Increases:

• Loss of Enhanced Premium Subsidies:  The American Rescue Plan and Inflation Reduction Act extended ACA subsidies through 2026. Without renewal, subsidized enrollees could see sharp increases in monthly premiums beginning in 2026 (KFF estimates more than a 75% jump in average out-of-pocket premiums for subsidized enrollees if the enhancements lapse). ¹

• Medical Cost Inflation:  Leading consultancies report elevated medical cost trends heading into 2026—about 7.5% in the individual market and 8.5% in the group market ⁵ —driven by hospital/physician services and prescription drugs.

• Regulatory Shifts:  Market rules and state laws have influenced filings. For example, analysts note federal policy changes (e.g., the Marketplace Integrity rule) as a factor cited in filings, adding operational uncertainty for vertically integrated insurers/PBMs.

Dividing retirement assets in a QDRO proceeding requires a clear understanding of what DTE Energy offers through its benefit programs. As an employee, you should know that DTE Energy maintains an active defined benefit pension plan, which means eligible employees continue to accrue benefits based on years of service and compensation. If you are eligible for a lump sum payout, IRS Section 417(e) segment rates determine how the future annuity stream converts to a present-value payment - rising rates compress the lump sum, so monitoring the plan's stability period and lookback month is critical before you lock in your election date. The choice between a single-life annuity, a joint-and-survivor option, or a lump sum (where available) is generally irrevocable once made, and timing that decision relative to interest rate conditions can meaningfully affect your retirement income picture.

On the medical coverage front, DTE Energy provides continued medical coverage to eligible retirees, which can bridge the gap between retirement and Medicare eligibility at age 65 or serve as a supplement to Medicare thereafter. Confirming the service and age requirements for retiree coverage, and understanding your premium contribution, is an important step in building an accurate healthcare cost projection. Coordinating DTE Energy's retiree coverage with Medicare Part B and Part D enrollment timing can also reduce duplication and avoid late-enrollment penalties. Bringing every piece of your DTE Energy benefits together inside a single retirement income framework is the surest way to see the full picture.
