Enhanced premium tax credits expired January 1, 2026. By late January, 1.2 to 1.4 million fewer Americans had enrolled for marketplace coverage, with total 2026 enrollment at 22.8–22.9 million.
Average premiums for subsidized enrollees jumped 114%—from $888 to $1,904 annually—while Trump administration tax credit changes deepened the shock. State exchanges reported steep declines: California's new sign-ups fell 32%, Massachusetts lost 13,000 enrollees, and Mississippi expects 200,000 to abandon coverage. The predicted shock is unfolding.
But the political rescue effort has collapsed: the House passed a three-year extension (230-196 on January 8, with 17 Republican votes), but Senate Republicans rejected it. A bipartisan group led by Sens. Moreno and Collins spent six weeks negotiating a narrower deal before talks stalled in early February over abortion, income caps, and health savings account design. The FY2026 funding bill passed without ACA provisions, leaving millions facing doubled premiums through 2026 with no legislative rescue.
Sen. Bernie Moreno, a key negotiator in the bipartisan working group, declares talks to revive ACA subsidies 'effectively over,' citing disagreements over abortion coverage, income caps, and health savings account design. Prospects for a compromise are now 'increasingly bleak,' according to negotiators on both sides.

Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
1 of 3
2017
2017 Republican Effort to Repeal the Affordable Care Act
After years of promising to repeal Obamacare, Republicans used unified control of government to push several repeal‑and‑replace bills, including the Graham‑Cassidy plan. A dramatic late‑night vote with Sen. John McCain’s thumbs‑down sank the final effort, preserving the ACA but exposing the political risk of stripping coverage outright.
Then
Obamacare survived, and Republicans took heavy political fire for threatening millions’ coverage.
Now
The party largely abandoned frontal repeal, shifting to quieter efforts to weaken the law’s mechanics.
Why this matters now
Today’s subsidy cliff is a subtler sequel: instead of repealing the ACA, Congress is letting its financial lifeline fray, risking comparable coverage losses with less transparent fingerprints.

2013–2014
2013 ACA Rollout and the ‘If You Like Your Plan’ Backlash
When key ACA rules kicked in, many individual‑market plans were canceled or reshaped, contradicting President Obama’s reassurance that people could keep coverage they liked. Technical failures on HealthCare.gov and reports of premium hikes fueled public anger and contributed to Democrats’ bruising losses in the 2014 midterms.
Then
The administration rushed out fixes and transitional policies, but Democrats paid a steep political price.
Now
The episode cemented ‘rate shock’ and plan disruption as explosive electoral issues for both parties.
Why this matters now
The 2026 subsidy cliff could trigger a new wave of rate shock stories, this time hitting voters under a Republican‑run Washington, with similarly unpredictable political consequences.

2017–2018
2017–2018 Lapse and Rescue of Children’s Health Insurance Program (CHIP) Funding
Congress allowed federal CHIP funding to expire for months, forcing states to draft shutdown plans and warning letters to families. After mounting public pressure and headlines about children losing coverage, lawmakers finally passed a long‑term funding extension with broad bipartisan support.
Then
States avoided mass disenrollment at the last minute, but families endured months of uncertainty.
Now
The episode showed Congress will sometimes flirt with coverage cliffs before scrambling to fix them under pressure.
Why this matters now
The ACA subsidy fight may follow a similar script: leaders tolerate a cliff to gain leverage, then move belatedly when real people’s coverage is on the line.
