• The Trump administration asserts it has support from both sides of the aisle for its "One Big Beautiful Bill Act" (OBBBA), which would reshape U.S. health insurance through cost containment measures and increased state control.
  • Critical ACA premium tax credit enhancements are set to expire at the end of 2025, with KFF analysis predicting some enrollees could see premiums more than double in 2026 without congressional action.
  • Policy analysts warn the proposed changes could lead to approximately 17 million Americans losing coverage over the next decade, primarily affecting lower- and middle-income individuals.

A Contentious Path Forward

The Trump administration is making a renewed push for its signature health insurance legislation, with officials claiming they've found unexpected bipartisan support for elements of the "One Big Beautiful Bill Act." According to people familiar with the matter, administration officials have been quietly meeting with moderate lawmakers from both parties to build consensus around certain cost-containment measures.

"We're seeing real interest from across the political spectrum on bringing down healthcare costs," said one administration official who asked not to be identified discussing private conversations. The official pointed to recent executive actions targeting prescription drug prices and greater price transparency as areas where common ground might be found.

The Looming Subsidy Cliff

Market participants are increasingly focused on the approaching expiration of enhanced premium tax credits at the end of 2025. The Congressional Budget Office estimates that without intervention, the changes could leave millions uninsured and significantly alter risk pools in the individual market. Insurance executives have been quietly preparing for potential market disruption, with several major carriers already submitting 2026 rate proposals that anticipate higher costs.

A KFF analysis circulating among industry stakeholders suggests some ACA marketplace enrollees could see their premiums increase by more than 100% if the enhanced subsidies expire as scheduled. "The industry is facing a fundamental reshaping of the individual market," said a healthcare analyst at a major financial services firm. "Carriers that have built their business models around the current subsidy structure may need to rapidly adapt."

State Control and Work Requirements

Central to the OBBBA proposal is shifting significant authority to states, including new work requirements for Medicaid expansion enrollees that would take effect in 2027. Several Republican-led states have already begun preparing waiver applications in anticipation of the changes, while Democratic attorneys general in multiple states have signaled they would challenge the requirements in court.

The legislation would also shorten the ACA open enrollment period and implement new verification steps for subsidy eligibility—changes that consumer advocates warn could further reduce coverage rates. "We're looking at a perfect storm of coverage losses," said a policy director at a healthcare advocacy organization. "Between the expiring subsidies, new administrative barriers, and work requirements, access to affordable coverage could become significantly more difficult."

Hospital systems and providers are particularly concerned about the potential increase in uncompensated care that could result from coverage losses. Several hospital chains have begun stress-testing their financial models against various coverage reduction scenarios, with some analysts predicting the changes could pressure margins by 2026.

The Road Ahead

With major provisions of the legislation scheduled to take effect before the 2026 insurance plan year, the political battle over the OBBBA is expected to intensify in coming months. Administration officials remain optimistic they can secure enough support to move forward with at least portions of their agenda, while opponents are mobilizing to block what they describe as the most significant rollback of health insurance protections in over a decade.

Correction: An earlier version of this article misstated the implementation timeline for Medicaid work requirements. They would take effect in 2027, not 2026.
