How Has Marketplace Enrollment Changed Across States in 2026?

Following several years of rapid enrollment growth in the ACA Marketplaces that corresponded with temporary enhanced premium tax credits, enrollment fell for the first time in seven years in 2026, when those tax credits expired. Every state except for New Mexico saw a drop in Marketplace enrollment from 2025 to 2026. State-based Marketplaces that run their own enrollment platforms, including those that partially offset the enhanced tax credits, generally saw lower drops in enrollment.
