ACA Marketplaces See Robust Enrollment, So Far

Nearly 4.6 million people have enrolled in Affordable Care Act marketplace coverage since the start of the 2024 open enrollment period on Nov. 1, a 36% increase compared to the same point during the 2023 OEP, according to CMS. This year’s open enrollment season will last from Nov. 1, 2023, to Jan. 15, 2024, in most states and longer in some state-based marketplaces (SBMs).

More than 4 million people have enrolled through HealthCare.gov in the 32 states that use that platform, and another 501,962 have enrolled across 18 states and the District of Columbia, which use their own marketplaces. Most states are seeing significant membership growth in 2024 compared with the same period last year. Mississippi reported a signup surge of almost 114%.
