Healthcare costs could triple for millions of people The subsidies have been essential for people buying healthcare through Obamacare. In 2025, 24 million individuals obtained insurance through the ACA marketplace, and the Center on Budget and Policy reports that 93% of enrollees received tax credits that helped reduce their costs. If Obamacare subsidies do expire, though, marketplace estimates say that premiums could double—or even triple— for those 22 million Americans who receive enhanced subsidies that make health premiums cheaper. According to health policy research group KFF 57% of ACA marketplace enrollees live in Republican congressional districts. Older adults and seniors are particularly at risk of losing access to their healthcare, since the subsidies spurred a 50% reduction in the uninsured rate among Americans 50 to 64. The Congressional Budget Office (CBO) also estimates that, with ACA expirations, about 4 million more people would become uninsured than would otherwise be the case.
