Health insurance premiums for Californians buying coverage through Covered California will rise by an average of 10.3% in 2026, the state marketplace announced Thursday. 

Overview

  • Insurers have submitted preliminary 2026 filings requesting a median 18% rate increase nationally, with more than 125 carriers seeking hikes of 20% or higher driven by medical inflation and costly drugs like GLP-1s.
  • The Trump-era Marketplace Integrity and Affordability Rule now factors individual market premium increases into inflation calculations, raising applicable percentages and allowable out-of-pocket limits for enrollees.
  • Covered California announced a 10.3% average premium increase and unveiled $190 million in state subsidies, yet warns that lapse of federal enhancements could drive net premiums up about 66% for 1.7 million people.
  • Analyses from KFF and Peterson-KFF project that expiration of enhanced ARPA credits would boost out-of-pocket premiums for subsidized enrollees by roughly 66%–75%, risking substantial coverage losses and adverse selection.
  • With open enrollment set to begin November 1, state rate approvals are pending and Congress remains the pivotal actor to prevent an affordability shock by year-end.
