The ACA MarketplaceS

Change in February effectuated enrollment, by state, 2025-2026

How Has ACA Marketplace Enrollment Changed Across States in 2026?

ACA Marketplace enrollment fell this year in every state except New Mexico, which was the only state to fully replace the enhanced premium tax credits that expired last year with a state-funded subsidy, according to a new KFF analysis of effectuated enrollment data. The Marketplace enrollment decline—the first in seven years—follows several years of rapid enrollment growth and coincides with the end of the enhanced federal subsidies.

How Much and Why ACA Marketplace Premiums Are Going Up in 2027

ACA Marketplaces insurers are proposing a median premium increase of 15% in 2027, according to KFF’s updated analysis of 276 insurers with publicly available filings across all 50 states and the District of Columbia. This is the second consecutive year of double-digit premium hikes. Last year’s median nationwide proposed rate change was 18%, and the median finalized rate change was 20%. While this proposed rate change is lower than last year, it represents the second-highest requested rate change since 2018, as premium growth had been relatively flat in this market for several years.

KFF’s Cynthia Cox examines the ACA’s record and the broader underlying question it raises: what’s a fair price for Americans people to pay for health care?

  • Pulling it Together: The “Third School” for Controlling Health Care Costs?

    Perspective

    For as long as I have been in the field, there have been two dominant schools of thought about how to control health care costs. One school, The Regulators, believed that the best way to slow increasing costs was to control the total resources going into the health care system: putting limits on the supply of medical professionals, technology and facilities; setting payment rates; or putting enough purchasing power in the hands of government to…

  • Pulling it Together: The Most Popular Provision in the ACA?

    Perspective

    In our most recent monthly tracking poll, we asked the American people what elements of the health reform law they like and dislike. Surprisingly, the runaway favorite was a relatively obscure requirement that health plans provide consumers with a short, easy to understand description of their benefits and coverage. Sixty percent of the American people gave this requirement for greater transparency in health insurance benefits a very favorable rating, the only provision in the law…
