Largest Increase Ever From Top Insurers. Will Group 1 Automotive Employees Be Affected?

Healthcare Provider Update: Healthcare Provider for Group 1 Automotive Group 1 Automotive typically utilizes major insurance providers like UnitedHealthcare, Cigna, and Aetna to offer health benefits to employees. However, specific plan details and healthcare provider partnerships may vary by location and plan year, so referring directly to their employee benefits information is advisable for the most accurate and tailored details. Potential Healthcare Cost Increases in 2026 In 2026, healthcare costs are projected to rise significantly, driven by a convergence of issues including the anticipated expiration of enhanced federal subsidies for Affordable Care Act (ACA) plans. Without these subsidies, many consumers could face out-of-pocket premium increases of over 75%, affecting approximately 92% of marketplace enrollees. Additionally, overall medical costs are rising as providers seek higher reimbursements to cope with inflationary pressures, resulting in insurers proposing average premium increases approaching 20%. As such, employees of Group 1 Automotive and others could see substantial hikes in their healthcare expenses, necessitating a thoughtful consideration of their healthcare plans and budgeting for the forthcoming year.

• In this article we will discuss:

  1. The expected premium increases for ACA marketplace plans in 2026 and their potential impact on Group 1 Automotive 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 Group 1 Automotive 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 2025, average out-of-pocket premium payments for subsidized enrollees could rise by more than 75% in 2026. ¹  As of January 2025, 24.2 million people selected 2025 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).

  • 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 2025. 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.
