GLP-1s, cancer care are driving higher employer health care costs in 2026

Employers anticipate a median 9% increase in healthcare costs next year, according to a Business Group on Health survey covering 11.6 million lives, primarily driven by rising expenses for GLP-1 drugs, cancer treatments, and mental health services. This significant cost spike is expected to prompt companies to intensify scrutiny of health insurance carriers and third-party vendors, seeking alternative cost management strategies, which could ultimately lead to higher premiums or deductibles for employees despite efforts to mitigate the impact.

Analysis

A survey of 121 large employers covering 11.6 million people indicates a significant acceleration in healthcare costs, with a projected median increase of 9% for the upcoming year. This spike is primarily driven by structural factors, including the high cost of GLP-1 weight-loss drugs, advanced cancer treatments, and expanded mental health services. In response, corporations are expected to intensify their cost-management strategies, focusing on more aggressive scrutiny of health insurance carriers and other third-party vendors. This suggests a potential shift in the power dynamic between employers and insurers, with companies actively seeking alternatives to control expenses. While the report notes that employers will attempt to shield employees from the full impact, the magnitude of the cost increase raises the probability of higher insurance premiums and deductibles being passed on to workers, which could in turn pressure corporate margins and employee disposable income.

Key Decisions for Investors

• Investors should monitor health insurance and PBM stocks for signs of margin compression, as increased scrutiny from corporate clients demanding better cost controls could intensify competition and pricing pressure.
• Companies with significant exposure to GLP-1 drugs, oncology, and mental health services may face greater pushback on pricing and formulary access as employers and insurers target these key cost drivers.
• Consider the impact of rising healthcare expenses as a potential headwind to corporate earnings across all sectors, particularly for labor-intensive industries where employee benefits constitute a major operational cost.
• Anticipate potential dampening effects on consumer discretionary sectors, as higher employee contributions to health insurance premiums and deductibles may reduce household disposable income.
