Many of the initial reports of premium increases for 2017 have been based on anecdotal examples or averages across insurers. This Kaiser Family Foundation brief takes a different approach, presenting an early analysis of changes in insurer participation and premiums for the lowest-cost and second-lowest silver marketplace plans in major cities in 16 states plus the District of Columbia where complete data on rates is publicly available for all insurers. Based on insurer rate requests, the cost of the second-lowest silver plan in these cities will increase by a weighted average of 9% in 2017.
