Marketplace insurers have requested a median 15 percent premium increase for 2027, according to KFF’s review of public rate filings. That is a request, not the price that has been finalized for every plan. KFF examined filings from 276 insurers across all 50 states and the District of Columbia, which makes the figure a nationwide midpoint across a large set of proposed changes rather than a single insurer’s announcement.
The proposed figure also comes with a useful warning from last year. KFF says the median requested change for 2026 was 18 percent, while the median finalized change was 20 percent. The comparison does not establish what the final 2027 figure will be. It does show why a requested rate should not be presented as a finished premium: the request and the final result can differ, including in the direction of a larger finalized increase.
The 15 Percent Number Is a Median Request
KFF’s central finding is deliberately narrow. The organization found a median proposed increase of 15 percent among the public 2027 filings it reviewed. “Median” means the middle requested change in the set KFF measured; it does not mean every marketplace enrollee, state, insurer, plan or county will see a 15 percent increase. The number is a way to describe the middle of the filing distribution, not a universal price notice.
The 276 filings covered insurers operating across all 50 states and the District of Columbia. That nationwide reach makes the result more informative than a filing from one carrier, but it does not turn the filing process into a final rate announcement. Insurers submit requests, and the word “requested” is part of the fact KFF reported. A headline that said insurers have finalized a 15 percent increase would go further than the research supports.
KFF describes the 15 percent median request as the second-highest requested rate change since 2018. That is a ranking of proposed changes, again not a final rate ranking. The context is important because rate filings can later change. The proper current description is that insurers have asked for increases whose median is 15 percent in the public filings KFF analyzed.

Last Year’s Filings Illustrate the Gap
The prior year supplies the best reason to keep the term of art straight. KFF says insurers’ median proposed change for 2026 was 18 percent. After the rate process was complete, the median finalized change was 20 percent. That does not make 20 percent a formula for 2027, and KFF does not say it is. It shows only that proposed and finalized changes are separate figures and that the final figure can move after initial filings are made public.
For 2027, the 15 percent number remains at the request stage. It should be read as a signal about what insurers have put forward, not as a promise that a particular premium will rise by that amount. The final result can vary across filings, and the article does not infer a final national median from KFF’s 2026 comparison.
That distinction is especially important in coverage discussions because a percentage can look more settled than it is. The source offers a measured filing analysis: 276 insurers, every state and D.C., a median 15 percent requested increase, and a comparison to last year’s proposed and finalized medians. It does not offer a final 2027 table for every enrollee or every plan.
What Is Driving the Requests
KFF attributes the requested increases to several pressures named in the filings and analysis: health-care prices, inflation, labor shortages, expiration of enhanced premium tax credits, and rising morbidity in the risk pool. Those are the factors KFF identifies behind the proposed rate changes. They are not separate agency determinations that every insurer has the same cost increase or that every plan will assign the same weight to each factor.
The expiration of enhanced premium tax credits is relevant to the filing environment, but it is different from the rate request itself. A premium tax credit affects what a qualifying enrollee pays after assistance; a rate filing describes what an insurer is asking to charge for coverage. KFF’s analysis places both developments in the 2027 premium discussion without treating them as the same calculation.
The practical takeaway from the source is a status check, not a certainty claim. The current nationwide median request is 15 percent. The final median has not been reported in KFF’s filing analysis. Last year’s numbers demonstrate why the proposed label belongs next to the 2027 figure every time it is repeated.
Separating Plan Prices From Coverage Rules
Rate filings can change before a final plan price is known, and the same kind of distinction appears throughout later-life health coverage: a premium, a drug cost and an appeal right do not come from the same rule. Medicare cost help also depends on separate state programs and plan records.
