Market Value:
- Lilly’s dominance in GLP-1 drugs (obesity/diabetes) fuels its $820 billion valuation.
- J&J and AbbVie maintain stability via diversified portfolios.
Regional Growth:
- U.S. remains the largest market (e.g., 64% of Lilly’s sales), but Europe and emerging markets gain traction.

- Patent cliffs (e.g., Humira) and trial failures (e.g., BMS’s Camzyos) threaten growth.
- Regulatory pressure on drug pricing may impact margins.

Summary

The U.S. pharmaceutical sector in 2025 is defined by disruption (Lilly’s obesity drugs) and resilience (J&J, Merck). Companies face pressure to innovate in oncology, metabolic diseases, and gene therapies, with mergers and pipeline expansion driving competition. Traditional giants must balance R&D investments with patent expirations, while newer players like Vertex and Regeneron carve niches in specialized markets.
