The Centers for Medicare & Medicaid Services (CMS) released the Health Insurance Exchanges 2025 Open Enrollment Report. The report summarizes data on health plan selections through the individual Exchanges during the 2025 Open Enrollment Period (OEP). This report includes OEP data for the 31 states with Exchanges that use the HealthCare.gov eligibility and enrollment platform for the 2025 plan year, as well as for the 20 State-based Exchanges (SBEs) that use their own eligibility and enrollment platforms.
During the 2025 OEP, 24.3 million consumers selected or were automatically re-enrolled in health insurance coverage through the HealthCare.gov platform and SBEs. Nearly 2.9 million more consumers signed up for coverage during the 2025 OEP compared to the 2024 OEP, a 13% increase. Nearly 8 million more consumers signed up compared to the 2023 OEP, and 9.8 million more consumers signed up compared to the 2022 OEP, a 49% and 68% increase, respectively.
CMS also released the associated Public Use Files (PUFs) with state, county, plan, and demographic-level data for the 2025 OEP.
