ACA Marketplaces Continue to See Record-Breaking Enrollment

Over 20 million people have enrolled in Affordable Care Act marketplace coverage since the start of the 2024 open enrollment period (OEP), reaching a record for the third consecutive year, according to CMS. Over 3.7 million people who have signed up for ACA plans are new enrollees this year.

More than 15.5 million people have enrolled through HealthCare.gov in the 32 states that use that platform, and another 4.8 million have enrolled across 18 states and the District of Columbia, which use their own marketplaces.

After adjusting enrollment figures to account for the fact that there is one fewer day included in the 2024 OEP data compared to last year’s report, an ACAsignups.net analysis showed that every state except Maine and the District of Columbia saw membership growth in 2024, ranging from 2.8% in Hawaii to 78.8% in West Virginia. A total of 10 states reported signup surges of more than 50%.
