Ohio's Obamacare enrollment plummets as phantom sign-ups and subsidy cuts take effect

Between February 2025 and February 2026, Ohio's Affordable Care Act enrollment contracted from 497,443 to 336,058, a 32.4% reduction that dwarfs the national average, according to CMS data cited by Signal Ohio. The Paragon Institute attributes much of the loss to the purge of “phantom” enrollees—individuals who never filed a claim—who made up 35% of Ohio's 2024 roster. Institute president Brian Blase said aggressive broker practices and inflated subsidies previously drove a surge in sign-ups, and tighter eligibility reviews have now removed many ineligible participants.

Heritage Foundation policy expert Edmund Haislmaier warned that CMS figures omit broader market data; quarterly insurer filings show a 13.2% drop, with Centene Corporation's enrollment falling 45%. Both analysts cite fraud schemes that enrolled low-income residents without consent, often using stolen Social Security numbers or promises of cash incentives. As subsidies receded, many legitimate enrollees likely moved to employer plans, Medicaid, health-sharing arrangements, or other exchange products. The overall picture suggests a combination of fraud cleanup, policy changes, and shifting coverage sources behind Ohio's sharp enrollment decline.
