Research and Markets Report (May 21): GLP-1 Agonists Weight Loss Drugs Market $15.5B in 2025 → $18.02B in 2026 (16.3% CAGR), Major Players Novo, Lilly, Pfizer
A May 21 Research and Markets report projected the global GLP-1 receptor agonist weight loss drug market expanding from $15.5B in 2025 to $18.02B in 2026 — a 16.3% compound annual growth rate. The forecast tracks through 2030 and 2035 across major players Novo Nordisk, Eli Lilly, and Pfizer, plus the growing oral GLP-1 segment (Wegovy pill, Foundayo, Structure Therapeutics' aleniglipron entering Phase 3). By 2020 roughly 4 million people were on GLP-1s; by 2026 that estimate has reached 30 million. The market data is the formal backdrop for the broader 2026 obesity-pharmacology conversation: GLP-1 alone is now larger than the 2024 oncology drug class's largest single product. The IQVIA peptide-CDMO capacity-build wave (Bachem, PolyPeptide, CordenPharma SPPS expansions through 2028) and the Lilly $4.5B Lebanon Indiana investment lean directly into the demand projection.
