How much and why ACA Marketplace premiums are going up in 2026 - Peterson-KFF Health System Tracker

For 2026, across 312 insurers participating in the ACA Marketplaces from the 50 states and the District of Columbia, this analysis shows a median proposed premium increase of 18%, which is about 11 percentage points higher than last year. This is the largest rate change insurers have requested since 2018, the last time that policy uncertainty contributed to sharp premium increases.

key factor driving costs in 2026. Insurers cite increasing cost and utilization of high-priced drugs as well as general market factors, such as increasing labor costs and inflation, as contributing to premium increases.

In addition to rising healthcare costs, the majority of insurers are also taking into account the potential expiration of enhanced premium tax credits in their premium rate increases for the next year. The expiration of enhanced tax credits will lead to out-of-pocket premiums for ACA marketplace enrollees increasing by an average of more than 75%, with insurers expecting healthier enrollees to drop coverage. That, in turn, increases underlying premiums. Other federal policy changes, like the implementation of tariffs and the ACA Marketplace Integrity and Affordability rule were also discussed, though to a lesser extent.
