ACA Marketplace insurers are proposing a median premium increase of 14% for 2027— indicating a likely second consecutive year of double-digit increases, according to a new analysis of preliminary rate filings in 16 states and DC.

After the enhanced tax credits ended, many Marketplace shoppers shifted toward lower-premium, higher-deductible plans.
