The Trump administration removed 760,000 Affordable Care Act enrollees last week after concluding they were fraudulently enrolled. Shares of Centene, Molina, Elevance, and UnitedHealth have fallen as the crackdown leaves insurers with a sicker, costlier patient pool. The removals come as 2027 premium rates are already locked, preventing insurers from repricing for the shift.

Key Facts

Vice President JD Vance announced last week that 760,000 ACA enrollees were dropped after the government concluded they did not exist or were enrolled without their knowledge.
Another 400,000 enrollees are under review, and the administration has barred hundreds of brokers and closed the marketplace to new entrants.
Brokers bring in 75% of marketplace enrollees, according to government data.
Premium rates for 2027 have already been approved and locked, so insurers cannot reprice to account for the enrollment shift.
Enhanced COVID-era subsidies expired at the end of 2025, prompting millions to drop coverage and pushing premiums up further.

Enrollment Fraud Crackdown

Vice President JD Vance announced last week that 760,000 ACA enrollees had been dropped after the government concluded they either did not exist or had been enrolled by brokers without their knowledge. Another 400,000 are under review, and the administration has additionally barred hundreds of brokers and closed the marketplace to new entrants. CMS said the cancellations followed a standard verification process targeting enrollees signed up by a broker who lacked key identification information, such as a Social Security number. Enrollees removed through the process have a path back to coverage if they successfully confirm their identity, the spokesperson added.

Insurer Profit Pressure

Shares of Centene, Molina, Elevance, and UnitedHealth have all fallen since Vice President JD Vance announced the removals last week. With fewer healthy, low-utilization members in the risk pool, insurers could face a disproportionately ill and costly patient base that squeezes margins through the rest of 2026 and the following year, investors and analysts warned. The premium rates for 2027 have already been filed, and at this point, they've all been approved and locked down, Matt McGough, a KFF policy expert, told Reuters. Insurers will likely respond by pushing rates higher for 2028, according to Reuters, citing three investors and two policy experts.

Broker Channel Impact

Brokers bring in 75% of marketplace enrollees, according to government data. Mike Smith, president emeritus at The Brokerage Inc. in Flower Mound, Texas, said the fraud announcement combined with new restrictions on brokers would push consumers away from using brokers altogether. People will think negatively of the 'fraudulent insurance brokers' and paint all of the good brokers with a wide brush, Smith said. The broader affordability problems that have driven double-digit premium increases and a wave of insurer exits began when enhanced COVID-era subsidies expired at the end of 2025, prompting millions to drop coverage and pushing premiums up further for those who remained.
