ACA Marketplace Full-Price Premiums Set to Rise About 13% for 2027, KFF Finds

Average full-price premiums for federal and state-run ACA marketplace plans are set to rise roughly 13% for 2027, according to KFF analysis reported October 31, 2026. Full-price means the premium before federal premium tax credits, so what subsidized enrollees pay is a separate calculation. Open enrollment began November 1 in most states.
