The Affordable Care Act, commonly known as Obamacare, has been a cornerstone of health insurance in the United States since its inception. Providing access to coverage for millions, it’s constantly evolving through legislative changes, new regulations, and market dynamics. As we look ahead to 2026, there are several significant updates and trends that individuals and families relying on the ACA Marketplace need to be aware of. The coming year brings both challenges and opportunities in securing affordable health coverage.
Potential Premium Hikes on the Horizon
One of the most pressing concerns for ACA enrollees in 2026 is the potential for significant premium increases. Preliminary analyses from various health policy research groups, including KFF and the Peterson Center on Healthcare, suggest that insurers are proposing a median premium increase of around 15% for 2026. This would be the largest hike in premiums for the ACA Marketplace since 2018.
Several factors are contributing to this projected rise. A major one is the scheduled expiration of enhanced premium tax credits at the end of 2025. These subsidies, which were expanded during the pandemic and extended by the Inflation Reduction Act, significantly lowered out-of-pocket premium payments for many Americans. Without congressional action to extend them, millions could see their monthly costs jump by an average of more than 75%. For example, a family of three earning $110,000 annually, currently paying around $779 for a silver plan, could see their monthly bill soar to over $1,400 in 2026. This potential “sticker shock” could lead to a substantial number of healthier individuals dropping coverage, further impacting the risk pool and potentially driving premiums even higher for those who remain.
Beyond the subsidies, underlying medical costs continue to rise due to inflation, increased prescription drug spending (especially for new and expensive therapies like obesity drugs), and continued high demand for behavioral health services. Furthermore, the possibility of tariffs on imported pharmaceuticals and medical equipment could add another layer of cost to insurers, which will likely be passed on to consumers.
Tighter Enrollment Rules and Verification
For 2026, the Centers for Medicare & Medicaid Services (CMS) has finalized a new Marketplace Integrity and Affordability rule that introduces stricter guidelines for enrollment and eligibility verification. This rule, designed to “protect consumers from improper enrollments and changes to their healthcare coverage” and ensure “subsidy integrity,” will impact how people enroll and re-enroll in ACA plans.
Key changes include:
- Shorter Open Enrollment Period: CMS has proposed ending the annual Open Enrollment Period by December 15th, instead of January 15th, starting with the 2027 plan year, though some stricter verification requirements are set for 2026. This shortens the window for individuals to select or change plans.
- Elimination of Special Enrollment Periods (SEPs) for Low-Income Enrollees: A specific year-round SEP for individuals with household incomes at or below 150% of the federal poverty level may be eliminated. This change aims to curb improper enrollments but could make it harder for low-income individuals to get continuous coverage if they miss the regular enrollment window.
- Stricter Eligibility Verification: New rules will enforce more rigorous income documentation and eligibility checks, particularly for those receiving premium subsidies or enrolling through SEPs. This could mean more paperwork and a need for consumers to actively verify their eligibility, rather than relying on automatic re-enrollment in fully-subsidized plans.
- Prohibition on Gender-Affirming Care: A controversial provision in the new rule prohibits states from including gender-affirming care in the ACA’s list of essential health benefits subject to mandatory coverage. This has already sparked a lawsuit from over 20 Democratic-led states, arguing it could harm millions and strip coverage.
These changes reflect a shift towards tightening oversight and ensuring subsidies go to truly eligible individuals, but critics argue they could create barriers to enrollment and increase costs for states and consumers.
Impact on Rural Healthcare and Medicaid
The legislative changes influencing the ACA, including the “One Big Beautiful Bill” signed by the current administration, are expected to have a significant impact, particularly on rural healthcare. While the bill allocates funds for a “rural health transformation program,” experts fear it may not be enough to sustain already struggling rural providers due to cuts to public insurance funding.
New Medicaid work requirements, effective December 31, 2026, in 40 states, will mandate some enrollees to prove employment to maintain public health insurance, unless exempt. Research suggests such policies are more likely to lead to people losing insurance than gaining employment. This could further impact the risk pool in ACA marketplaces as individuals move between different types of coverage. Medicaid redeterminations, largely complete in 2025, will fully reflect in the individual market risk pool in 2026, with varied effects across states depending on the health needs of the transitioning cohort.
What Consumers Should Do for 2026
Given these anticipated changes, staying informed and proactive is essential for ACA enrollees in 2026:
- Prepare for Higher Premiums: Budget for potentially higher out-of-pocket costs. If the enhanced subsidies expire, your net premium could increase substantially.
- Act Early During Open Enrollment: With shorter enrollment windows and stricter verification, don’t wait until the last minute. Start researching and comparing plans well in advance of the Open Enrollment Period.
- Gather Documentation: Be prepared for more stringent eligibility verification by having accurate income and household information readily available.
- Review Your Plan Carefully: Don’t automatically re-enroll. Evaluate your current plan against new offerings. Check if your preferred doctors and hospitals are still in network, and understand any changes to benefits, especially regarding services like gender-affirming care if that’s a concern.
- Seek Assistance: Utilize resources from HealthCare.gov, state marketplaces, or qualified navigators and agents who can help you understand the changes and compare plans.
The Affordable Care Act continues to be a vital source of health coverage, but 2026 is poised to bring notable shifts in premiums, enrollment processes, and coverage specifics. Staying informed, preparing for potential financial adjustments, and acting proactively during the enrollment period will be key to maintaining robust and affordable health insurance.
