An analysis of preliminary premium filings from ACA-regulated health plans across five states indicates an additional 5.58 percentage-point increase in premiums due to the projected expiration of enhanced subsidies under the Affordable Care Act. Insurers in Massachusetts highlighted their discontinuation of coverage for popular but costly anti-obesity GLP-1 drugs in their filings.
In May, House Republicans passed the “One Big Beautiful Bill Act,” which notably did not include an extension of the enhanced ACA subsidies. These enhanced subsidies increased the level of advance premium tax credits (APTCs) available to lower-income individuals (making $0-premium plans widely available to that group) and extended APTC eligibility to people with incomes at or above 400% of the federal poverty level. Without a permanent extension of the enhanced subsidies, subsidized ACA enrollees would see their premium payments rise sharply starting Jan. 1, 2026.
Over half of the insurers included in this analysis indicated that the expiration of enhanced APTCs would lead to premium increases. Among the insurers who quantified the impact, the projected increases, in addition to annual rate changes, ranged from 1.0% to 13.7%, with an average projected premium impact of about 5.58%. The analysis is based on 36 early insurer premium filings from Oregon, New York, Maryland, Vermont and Massachusetts.
Oregon
Six insurers have submitted rate change requests for 2026, ranging from an average increase of 3.9% to 12.9%, resulting in a weighted average increase of 9.7%, according to the Oregon Division of Financial Regulation. This average increase is slightly higher than last year’s requested weighted average increase of 9.3%. Four of the six insurers attributed part of the increases to the expiration of enhanced subsidies, which could raise premiums by 1.0% to 4.5%.
In 2025, the monthly average premium for all enrollees is $696 per person per month in the exchange. With the enhanced subsidies, the monthly average premium among those with allocated APTC amounts greater than $0 is $199. For the year 2025, about 80% of ACA enrollees received APTCs in Oregon, according to CMS.
New York
Fourteen insurers have submitted rate change requests for 2026, ranging from an average increase of 0.9% to 66.4%, according to the New York Department of Financial Services. Only five insurers specified how much of their premium increases were driven by the expiration of enhanced subsidies. The largest insurer in the state, Fidelis Care, attributed 3.90% of its requested rate hike to the policy change.
In 2025, the monthly average premium for all enrollees is $791 per person per month in New York’s state-based marketplace. With the enhanced subsidies, the monthly average premium among those with allocated APTC amounts greater than $0 is $340. For the year 2025, about 63% of ACA enrollees received APTCs in New York, according to CMS.
Maryland
Six insurers have requested an overall average rate increase of 17.1% for 2026, with individual insurer requests ranging from 8.1% to 18.7%, according to the Maryland Insurance Administration. In the news release, the agency noted that the rate increases “are the highest since the implementation of Maryland’s reinsurance program in 2019 and reflect the anticipated loss of enhanced federal tax credits.” If the enhanced tax credits were to continue, the projected average rate increase would drop to 7.9%.
The two largest insurers in the state, CareFirst BlueChoice and Optimum Choice, attributed 13.7% and 5.8% of their requested rate hikes to the anticipated policy change, respectively. In addition, CVS Health’s Aetna has announced plans to exit Maryland’s individual market in 2026, a move that will affect 4,939 enrollees.
In 2025, the monthly average premium for all enrollees is $492 per person per month in Maryland’s state-based marketplace. With the enhanced subsidies, the monthly average premium among those with allocated APTC amounts greater than $0 is $108. For the year 2025, about 76% of ACA enrollees received APTCs in Maryland, according to CMS.
Vermont
BlueCross and BlueShield of Vermont proposed a 23.3% average premium hike for 2026, while MVP Health Plan requested a 6.2% increase, according to Vermont’s Green Mountain Care Board. BCBSVT attributed 6.6% of its requested rate increase to the anticipated expiration of enhanced subsidies. MVP Health Plan noted that “a disproportionate share of healthy members are expected to leave the market,” resulting in an increased morbidity impact of 7.1%.
In 2025, the monthly average premium for all enrollees is $1,067 per person per month in Vermont’s state-based marketplace. With the enhanced subsidies, the monthly average premium among those with allocated APTC amounts greater than $0 is $192. For the year 2025, about 93% of ACA enrollees received APTCs in Vermont, according to CMS.
Massachusetts
Eight insurers have submitted rate change requests for 2026, with proposed average increases ranging from 9.90% to 16.20%, according to the Massachusetts Division of Insurance. Of these, only Fallon Community Health Plan Inc. — which accounted for 5.6% of individual market membership statewide — specified that 3.5% of its requested rate increase was due to the anticipated expiration of enhanced federal subsidies.
Unlike many other states, Massachusetts insurers also cited the rising costs of covering popular anti-obesity medications, specifically GLP-1 drugs, as a contributing factor to premium pressures. Five insurers — Tufts Health Plan, WellSense Health Plan (Boston Medical Center), Mass General Brigham Health Plan, Harvard Pilgrim Health Care and Blue Cross Blue Shield of Massachusetts HMO Blue, Inc. — announced they will no longer cover GLP-1 drugs for weight loss indications in 2026. Combined, these five insurers covered 92.2% of the state’s individual market.
In 2025, the monthly average premium for all enrollees is $535 per person per month in Massachusetts’ state-based marketplace. With the enhanced subsidies, the monthly average premium among those with allocated APTC amounts greater than $0 is $126. For the year 2025, about 83% of ACA enrollees received APTCs in Massachusetts, according to CMS.
