Small businesses across the United States are facing a significant financial challenge as health insurance premiums are projected to surge by an average of 14% in 2026, according to preliminary rate filings analyzed by the Kaiser Family Foundation (KFF). This anticipated increase, with some insurers seeking hikes as high as 20%, poses a substantial burden on employers, particularly those with fewer than 50 employees, who already struggle to offer competitive health benefits. The escalating costs are attributed to a confluence of factors, including the rising price and utilization of prescription drugs, particularly GLP-1 medications, and the ongoing impact of the No Surprises Act, which is driving up out-of-network reimbursement rates.
This projected surge in premiums comes at a critical juncture for employer-sponsored health insurance, the dominant form of coverage for an estimated 165 million working-age Americans. While offering health benefits has long been a cornerstone of employee compensation and a competitive advantage for businesses, the escalating cost of healthcare is increasingly straining company budgets. The KFF analysis, which examined rate filings from nearly 300 insurers across all 50 states and Washington, D.C., paints a stark picture of the financial pressures facing the small group insurance market.
The Mounting Burden on Small Employers
The statistics underscore the precarious position of small businesses in providing health coverage. In the past year, only 51% of firms with fewer than 25 employees offered health insurance, a stark contrast to the 97% of companies with 200 or more employees that provided such benefits. This disparity highlights the inherent challenges smaller enterprises face in absorbing the rising costs of health insurance. If the predicted double-digit premium increases materialize, this offering rate could decline further, potentially leaving more workers without employer-sponsored coverage.
Insurers are citing a rapid escalation in underlying medical costs as the primary driver for these proposed rate increases. These costs encompass a range of services, from hospitalizations to prescription medications, which are not only becoming more expensive but are also being utilized at higher rates by plan members.
"Costs for medical care and medications for our members have escalated rapidly and spending is now growing at the fastest rate in more than a decade," stated Blue Cross and Blue Shield of Massachusetts in its rate request to regulators. "The surge in spending is putting a heavy burden on our employer customers and members who are struggling to keep up with rising costs."
The GLP-1 Factor and Shifting Utilization
A significant contributor to these escalating costs identified in the rate filings is the increased demand and associated expense of GLP-1 medications. Originally developed for diabetes management, these drugs have seen a surge in popularity for weight loss and are also being explored for their potential benefits in treating other conditions. While some insurers have begun to discontinue coverage for anti-obesity treatments due to the high price tag of GLP-1s, the overall spending on these medications continues to rise as more individuals, including those with diabetes, access them. This trend is putting considerable pressure on insurer formularies and, consequently, on premium rates.
The No Surprises Act’s Unforeseen Consequences
Beyond the direct medical costs, the No Surprises Act (NSA), enacted in 2020 to protect consumers from unexpected out-of-network medical bills, is also contributing to the rise in premiums for the small group market. The law established a framework for resolving payment disputes between insurers and out-of-network providers. However, research suggests that providers are prevailing in a majority of these arbitration processes, often securing reimbursement rates significantly higher than contracted in-network rates.
Two insurers in New York, Oxford Health Insurance and UnitedHealthcare Insurance Company of New York, specifically cited the NSA’s impact in their rate filings, indicating that it would add approximately 0.8% to their premiums for the upcoming year. Both of these entities are subsidiaries of the insurance giant UnitedHealthcare, which recently reported higher-than-anticipated spending in its commercial business, attributing some of the increase to the NSA. This suggests a broader trend where the costs associated with NSA dispute resolution are being passed on to employers and their employees.
The Erosion of the Fully-Insured Market and the Rise of Alternative Plans
The persistent rise in premiums is prompting a shift in how small businesses procure health coverage. According to KFF data, the number of individuals enrolled in the fully-insured small group market has declined from 17 million in 2013 to 10 million in 2024. However, this decline in traditional insurance enrollment has not necessarily translated to a reduction in coverage rates for small business employees. Instead, many employers are migrating towards self-funded or level-funded products.
Level-funded plans, in particular, have gained traction. Under these arrangements, employers pay a fixed premium, with the potential for rebates if actual medical claims fall below projections. These plans can be more cost-effective for small businesses with a generally healthy workforce.
However, these alternative arrangements come with significant caveats. Level-funded plans are often not subject to the same stringent benefit requirements as plans regulated by the Affordable Care Act (ACA). This can allow insurers to adjust premiums or deny coverage based on pre-existing medical conditions and other risk factors, essentially cherry-picking healthier populations.
KFF researchers expressed concern that the continued popularity of these alternative options could further destabilize the fully-insured small group risk pool. "Continued growth in the popularity of alternative coverage options for small businesses, like level-funded plans, has the potential to further erode the fully-insured small group risk pool and could contribute to future premium increases for small businesses, particularly those with sicker employees who may not qualify for or are priced out of a level-funded arrangement," the report stated. This dynamic could create a cycle where healthier individuals and businesses opt out of the traditional market, leaving a sicker, more expensive pool for those who remain, thus driving up premiums further.
A Broader Economic Landscape and Future Outlook
The projected 14% median premium increase for the small group market in 2026 is notably higher than the 11% insurers requested for 2026, indicating a potential escalation in cost pressures. This rate hike is also comparable to the premium increases being proposed by insurers in the ACA marketplaces for the upcoming year. These exchange insurers are contending with their own financial pressures, including the expiration of enhanced federal subsidies, which have historically made coverage more affordable for individuals.
The current economic climate, marked by persistent inflation and rising healthcare expenditures, creates a challenging environment for both employers and employees. For small businesses, the ability to offer comprehensive health benefits is not only a matter of employee well-being but also a crucial factor in talent acquisition and retention. The prospect of significant premium increases in 2026 could force many to re-evaluate their benefits packages, potentially leading to higher deductibles, increased co-pays, or a reduction in covered services.
The implications of these rising costs extend beyond individual businesses. A substantial portion of the American workforce relies on employer-sponsored insurance. A widespread erosion of this coverage or a significant increase in its cost could have broader economic repercussions, impacting healthcare access, consumer spending, and overall workforce productivity. Policymakers and industry stakeholders will need to closely monitor these trends and explore potential solutions to mitigate the impact of these escalating healthcare costs on small businesses and their employees. The ongoing debate around healthcare affordability and accessibility is likely to intensify as the full impact of these premium increases becomes apparent.
