GLP-1 Coverage Fell From 72% to 60%. Is Eli Lilly’s Weight-Loss Boom Hitting an Insurance Wall?
Employer coverage of GLP-1 weight-loss drugs, including Eli Lilly's Zepbound and Mounjaro, dropped from 72% to 60% between 2025 and 2026. Despite this, Lilly's Q2 revenue grew 47.67% YoY to $22.97 billion, with Zepbound and Mounjaro contributing $4.93 billion and $9.94 billion, respectively. The decline in coverage is due to employers' budget constraints and the long-term nature of health benefits. Lilly is mitigating the impact through direct-to-consumer channels and lower-cost programs.
