Cigna To Leave Obamacare Exchanges As Enrollment, Subsidies Decline

In a significant blow to the long-term viability of the Affordable Care Act marketplace, Cigna announced it will withdraw from the exchanges beginning in 2027—becoming the second major insurer to step away amid growing uncertainty in the individual insurance market.

The move comes on the heels of expiring federal subsidies that had artificially propped up enrollment by lowering premiums for millions of Americans. Without those taxpayer-funded incentives, insurers are increasingly questioning whether participation in the ACA marketplace is financially sustainable.

Company executives disclosed the decision during Thursday’s earnings call, where Cigna reported stronger-than-expected performance, including $1.7 billion in net income for the first quarter, according to The Hill. Despite those gains, leadership made clear the Obamacare segment no longer fits into the company’s broader vision.

“We did not make this decision lightly, and appreciate the importance of ensuring patients have continuity through the transition,” said Brian Evanko, Cigna’s president and incoming chief executive.

Evanko emphasized that the ACA business has failed to grow into a meaningful segment for the company. “This is small business for us today, and it’s been shrinking in recent years,” he said.

Cigna’s exit will impact roughly 369,000 policyholders across 11 states—a relatively small share of its more than 18 million total members. Still, the withdrawal reflects a troubling trend. Enrollment in the company’s exchange plans has dropped sharply, falling from approximately 446,000 in early 2025 to 369,000 in 2026—a decline of nearly 17 percent.

The development follows a similar retreat by Aetna, which exited the ACA exchanges earlier this year. Together, these high-profile departures are raising fresh concerns about the structural stability of the Obamacare system.

Enrollment across the broader ACA marketplace has already begun to decline after Congress failed to extend enhanced subsidies that once made coverage “free” for some low-income enrollees and more affordable for middle-class families. With those subsidies gone, reality is setting in: costs are rising, and fewer Americans are signing up.

Initial enrollment dropped by approximately 1.2 million people this year alone, and analysts warn that higher premiums could accelerate the downward trend. Insurers now face mounting uncertainty as they prepare future pricing, with fewer healthy individuals remaining in the risk pool.

The Trump administration has pointed to another key factor behind the enrollment drop: efforts to root out fraud and ensure only eligible individuals receive coverage. Officials have argued that some of those losing insurance may never have qualified under the law in the first place.

Policy experts caution that the marketplace could enter a dangerous cycle. As premiums increase, younger and healthier individuals are more likely to opt out, leaving behind a sicker, more expensive pool of enrollees. That imbalance drives costs even higher—forcing insurers to raise premiums further or exit altogether.

While the current wave of insurer withdrawals has not yet triggered the kind of collapse seen in 2017—when some counties faced the prospect of zero exchange options—the warning signs are mounting. Affordability remains the central challenge, and without structural reform, the system’s long-term outlook remains in doubt.

The future of Obamacare is once again shaping up as a key political battleground. Democrats continue to push for expanded subsidies, while Republicans argue the law’s design flaws are the root cause of its instability—underscoring the need for market-based reforms and greater consumer choice.

Cigna says it will work to ensure a smooth transition for affected customers ahead of its 2027 exit, but the broader implications are clear: even major insurers are losing confidence in a system that increasingly appears unsustainable.
