Average benchmark premiums for Affordable Care Act marketplace plans are rising 13% for 2027, KFF reported, as open enrollment began Sunday after a 26% increase for 2026.

The two increases add up to about 42% since 2025, according to KFF's analysis, which attributes the rise to higher underlying care costs and changes in the risk pool after enhanced premium tax credits expired. Enrollment on HealthCare.gov runs through Jan. 15, 2027, the Centers for Medicare & Medicaid Services said, and the Congressional Budget Office projects marketplace enrollment will fall to 13.1 million in 2027 from a 2025 peak of 22.4 million.

Separately, a Doximity analysis of more than 8,500 dosing questions found general-purpose AI models gave seriously wrong or potentially lethal doses in about 2% of answers, and fewer employers are paying for GLP-1 weight-loss drugs, a WTW survey found.
