Eleven carriers set to quit ACA marketplaces for 2027 as enrollment shrinks
By Insurance Wire Staff, . Insurance Wire.
Eleven insurance carriers have announced they will leave Affordable Care Act (ACA) marketplace coverage for plan year 2027, either in all states where they currently operate or in selected ones, according to KFF, which has been tracking participation changes since June and updated its analysis through October 28, 2026. Seven carriers have announced they will enter new state marketplaces, but the net direction is clearly toward contraction.
What changed
The biggest single exit is Cigna, which is leaving all 11 states where it currently sells marketplace plans. Insurance Business Magazine reported that roughly 369,000 people are affected by Cigna's departure alone. Baylor Scott and White Health Plan is also exiting Texas, according to the same report.
Insurance News Net reported that Cigna's new chief executive framed the decision as a strategic exit from a market where the company is unlikely to achieve scale. The insurer's first-quarter on-exchange enrollment stood at over 350,000 individuals before the exit was announced.
Why the exits are happening now
The timing is directly tied to the expiration of enhanced premium tax credits at the end of 2025. Those credits, which temporarily reduced the cost of marketplace coverage for millions of Americans, helped push enrollment to record levels. Once they expired, sign-ups fell by over a million between the 2025 and 2026 open enrollment periods, according to the KFF analysis, with further membership declines expected as the year progresses.
A smaller pool of enrollees makes the economics harder for carriers. The analysis also flags a risk pool concern: when enrollment falls, it tends to be healthier people who drop coverage first, leaving a sicker, more expensive group behind. That dynamic raises costs for insurers and can accelerate the decision to exit.
Medical care prices rose 1.5 percent in the year through September 2026, according to the US Bureau of Labor Statistics. That is a relatively modest rate of increase, but it does not offset the structural pressure carriers face when their enrollment base shrinks and the remaining members use more care.
What it means for consumers and the market
In states where multiple carriers are exiting simultaneously, consumers will have fewer plans to choose from during open enrollment, which begins November 1. Less competition among remaining insurers typically means less pressure on premiums and plan design.
For agents and brokers, the practical consequence is a narrower product shelf in affected states and a harder conversation with clients who may have been enrolled with a departing carrier. Those clients will need to actively select a new plan during open enrollment or risk being auto-enrolled into whatever the exchange assigns them, which may not be the best fit.
The KFF tracker flags that its insurer data reflects sources current as of October 28, 2026, and the picture could shift before the plan year gets underway. The final picture will not be clear until the enrollment window opens and regulators publish confirmed carrier participation lists. Agents working in states with multiple announced exits should verify the current status of each carrier before advising clients.
