The ACA Marketplaces in 2025, at a Glance

HealthCare.gov enrollees have more health plan options in 2025 compared to previous years, yet the average benchmark plan premium in states that use the federal enrollment platform increased modestly, according to CMS.

In most states, the open enrollment period for Affordable Care Act marketplace coverage runs from Nov. 1, 2024, to Jan. 15, 2025. Out of the 31 states that are using HealthCare.gov, eight have more Qualified Health Plan (QHP) issuers in 2025 than in 2024, and 97% of enrollees have access to three or more issuers, compared to 78% in 2021. Seven HealthCare.gov states have counties with a single QHP issuer in 2025, compared to nine states in 2024. Georgia stopped using HealthCare.gov in 2024 and transitioned to a state-run exchange, and Illinois is scheduled to move to a state-based marketplace for the 2026 plan year.
