Tracking Insurer Changes in the ACA Marketplaces in 2027

As of June 22, six carriers have announced that they will exit the Marketplaces in plan year 2027, either in some or all states that they are currently offering plans; four carriers have announced they will enter new Marketplaces.

An image of text is an excerpt from Cynthia Cox's quick take which reads, "While the Trump administration attributes this drop in enrollment to their attempts to address fraud, this coverage loss happened at the same time millions of people faced steep increases in their premium payments — often in the double or even triple digits — with the expiration of enhanced tax credits."

ACA Marketplace Enrollment Is Down By 3 Million After Big Jump in Premium Payments

Enrollment dropped 13% following the expiration of enhanced premium tax credits at the beginning of this year. Enrollment fell from a high of 22.1 million people in 2025 to 19.2 million people in February 2026. While the Trump administration attributes this drop in enrollment to their attempts to address fraud, this coverage loss happened at the same time millions of people faced steep increases in their premium payments – often in the double or even triple digits – with the expiration of enhanced tax credits.

    Medicaid is the health insurance safety net for nearly 60 million of the nation's poorest and sickest individuals. It provides access to a comprehensive scope of benefits with limited cost-sharing that is geared to meet the health needs and limited resources of the low-income, high-need populations it serves, populations for whom private coverage is often not available, not affordable or inadequate.

  • Pulling it Together: 19.7

    Perspective

    Several years ago Joanne Silberner from NPR offered some advice I liked. Joanne said that the secret to effective communication was to "have a killer anecdote and a killer number." Here is a killer number: 19.7. That's the average number of years between major attempts at health reform since Harry Truman made health reform a top priority and his plan was branded a socialist plot and soundly defeated in 1950. The chart below chronicles the…
