The health insurance marketplaces established under the Affordable Care Act (ACA), often called health exchanges, are facing a potentially turbulent year, according to early indicators. While enrollment figures have remained relatively stable in recent years, a confluence of factors—including rising premiums, insurer participation changes, and ongoing political debate—could create headwinds for the program in 2026. Understanding the dynamics of these marketplaces is crucial, as they provide access to health coverage for millions of Americans, and their stability impacts the broader healthcare landscape.
Since January 1, 2014, every state in the U.S., including the District of Columbia, has offered access to health and/or dental insurance through these exchanges, known as the Individual or Small Business Health Options Program (SHOP) Health Insurance Exchanges. These are operated either by states themselves through State-based Exchanges (SBEs), or by the federal government through the Federally-facilitated Exchange (FFE). The system was designed to expand coverage and foster competition among insurers, but its implementation has been complex and subject to ongoing adjustments.
For the Plan Year 2026, You’ll see currently 21 SBEs in operation, alongside 2 State-based Exchanges on the Federal platform (SBE-FPs). SBE-FPs rely on the Department of Health and Human Services (HHS) for certain functions, like eligibility and enrollment, while maintaining control over areas such as plan certification and consumer outreach. This hybrid approach reflects the varying levels of state commitment and capacity in administering these programs.
The Evolving Landscape of State-Based Exchanges
The initial vision of the ACA involved states taking the lead in establishing and running their own exchanges. Still, the path to full state control has been uneven. States were initially eligible for federal grants to support the establishment of SBEs, but that funding stream ended in November 2014. The Center for Consumer Information and Insurance Oversight (CCIIO) within CMS continues to provide conditional approval for states seeking to establish or maintain SBEs. CMS maintains a list of current SBEs and SBE-FPs, along with relevant documentation like declaration letters and conditional approval letters.
The decision to operate an SBE is significant, as it allows states to tailor the marketplace to their specific needs and priorities. However, it too requires substantial investment in infrastructure and expertise. States that opted for the federal exchange or SBE-FP model often cited cost concerns or political opposition as key factors. The ongoing debate over the ACA’s future continues to influence these decisions.
Challenges Facing the Exchanges
Several challenges could contribute to volatility in the health insurance exchanges this year. Rising healthcare costs are a persistent concern, leading to increased premiums for many consumers. While the ACA provides subsidies to help offset these costs, affordability remains a barrier for some individuals and families. According to data from the Kaiser Family Foundation, premiums have generally increased each year since the ACA was implemented, although the rate of increase has varied.
Another factor is the participation of insurers. Some major insurers have withdrawn from certain exchanges in recent years, citing financial losses or market instability. This reduces consumer choice and can lead to higher premiums in areas with limited competition. The health insurance marketplace is not itself an insurer, but determines which companies participate.
Political uncertainty also plays a role. Ongoing efforts to repeal or weaken the ACA create uncertainty for insurers and consumers alike. Changes to the law could disrupt the market and lead to coverage losses. The future of cost-sharing reduction payments, which help lower out-of-pocket costs for low-income individuals, remains a point of contention.
Enrollment Trends and Future Outlook
Despite these challenges, enrollment in the health insurance marketplaces has remained relatively stable in recent years. As of April 14, 2020, 11.41 million people had signed up through the marketplaces, and an additional 4.8 million joined Medicaid. However, enrollment numbers alone do not tell the whole story. It’s important to consider factors such as the demographics of enrollees, the level of subsidies they receive, and the quality of coverage they have access to.
Looking ahead, the health insurance exchanges will likely continue to evolve. States will need to adapt to changing market conditions and address the needs of their residents. The federal government will also play a role, through its oversight of the FFE and its implementation of ACA policies. The success of these marketplaces will depend on a combination of factors, including affordability, competition, and political stability.
The ongoing viability of the exchanges is also tied to the existence of private, non-ACA health care exchanges, which serve approximately 3 million people, primarily employees of small and medium-sized businesses. These exchanges predate the ACA and offer a different approach to health insurance coverage.
What to Watch in the Coming Months
The coming months will be critical for the health insurance exchanges. Insurers will be filing their rates for the 2027 plan year, and those rates will provide a key indicator of the market’s health. States will also be evaluating their exchange operations and making decisions about their future direction. Consumers should stay informed about their options and seize advantage of available subsidies to help make coverage affordable.
The next major checkpoint will be the open enrollment period for the 2027 plan year, which typically begins in November. This is when individuals and families can sign up for coverage through the exchanges. Updates on enrollment numbers and market trends will be released by CMS and state exchange officials in the months following the open enrollment period.
The health insurance exchanges remain a vital component of the U.S. Healthcare system, providing access to coverage for millions. While challenges exist, ongoing efforts to improve the marketplaces and address affordability concerns are essential to ensuring that everyone has access to quality, affordable healthcare.
