Market Valuation: Where Things Stand in 2026
Market sizing for peptide therapeutics varies widely depending on which molecules a given research firm includes. Estimates for 2025-2026 range from roughly $46 billion to over $117 billion. The discrepancy reflects scope: some firms count only traditional peptides, while others include insulin analogs and GLP-1 agonists broadly.
Here is how major research firms currently size the market:
| Source | 2025 Estimate | 2026 Estimate |
|---|---|---|
| Precedence Research | $52.59 billion | $56.06 billion |
| Towards Healthcare | $50.93 billion | $54.57 billion |
| Mordor Intelligence | $46.36 billion | ~$49.6 billion |
| Grand View Research | $117.26 billion (2024) | N/A |
The Grand View Research figure includes insulin and broad GLP-1 revenues. The more conservative estimates from Precedence and Mordor Intelligence use narrower definitions that focus on non-insulin peptide therapeutics.
For a reasonable mid-range estimate: the global peptide therapeutics market is worth approximately $50-56 billion in 2026, with GLP-1 receptor agonists accounting for the single largest revenue share.
Growth Projections: The 10-Year Outlook
Every major research firm projects steady growth through the mid-2030s, though the projected end points vary:

| Towards Healthcare | 2034 | $81.5 billion | 5.35% |
| Precedence Research | 2035 | $87.21 billion | 5.19% |
The most conservative estimates (Precedence, Towards Healthcare) project the market roughly doubling over the next decade. The most aggressive (Grand View Research, which uses the broadest scope) suggests a fivefold increase.
A reasonable consensus: the peptide therapeutics market will reach $80-90 billion by 2033-2035, representing a CAGR of 5-8%.
What Is Driving Growth
1. The Metabolic Disease Epidemic
Over 530 million people worldwide live with diabetes. More than 890 million adults are classified as obese. These numbers are rising, and peptide-based GLP-1 agonists like semaglutide and tirzepatide have become first-line treatments. The obesity drug market alone is projected to grow at an 18.5% CAGR through 2030.
2. Expanded Indications for Existing Peptides
GLP-1 drugs are being tested for conditions far beyond diabetes and obesity. Active or completed trials cover:
- Cardiovascular risk reduction (Wegovy's SELECT trial showed a 20% reduction in MACE events)
- Non-alcoholic steatohepatitis / metabolic-associated steatotic liver disease (MASLD)
- Chronic kidney disease
- Heart failure with preserved ejection fraction
- Obstructive sleep apnea (Zepbound is now approved for this)
- Addiction and neuropsychiatric conditions
- Alzheimer's disease
Each new approved indication expands the addressable market without requiring a new molecule.
3. Pipeline Depth
More than 150 investigational peptides are targeting proteins previously considered "undruggable." Over 170 peptide drugs are in active clinical trials globally. The industry has moved well beyond simple linear peptides into:
- Cyclic peptides with improved stability and oral bioavailability (66 cyclic peptide drugs approved globally as of mid-2024)
- Peptide-drug conjugates that combine targeting peptides with cytotoxic payloads for cancer
- Stapled peptides with constrained structures that resist degradation
- PEGylated peptides with extended half-lives enabling less frequent dosing
4. Oral Delivery Breakthroughs
Historically, peptides had to be injected because stomach acid destroyed them. That is changing. The FDA approved oral semaglutide for weight loss in December 2025, and orforglipron (a non-peptide oral GLP-1 agonist) is under review. Oral peptide delivery is expected to grow at a 6% CAGR over the next five years. Advances in permeation enhancers, enteric coatings, and formulation technologies are making more peptides viable as pills.
5. Personalized Medicine
Peptides offer advantages for targeted therapy: high specificity, lower off-target toxicity, and the ability to be engineered for specific receptor subtypes. This aligns with the broader pharmaceutical trend toward precision medicine, particularly in oncology and rare diseases.
Market Segmentation by Therapeutic Area

Peptides are well-suited for rare diseases due to their specificity. The orphan drug segment has been a consistent source of FDA approvals — half of all novel drug approvals in 2025 were for orphan indications.
Other Segments
Peptide therapeutics are also used in:
- Growth hormone deficiency (sermorelin, tesamorelin)
- Infectious disease (antimicrobial peptides)
- Neurology and psychiatry
- Immunology and autoimmune conditions
- Dermatology and wound healing
Market Segmentation by Route of Administration
Parenteral (~84% of revenue)
Injectable peptides dominate the market. Subcutaneous injection remains the standard for most peptide therapeutics, including all currently approved GLP-1 agonists (injections). Advances in autoinjector design and once-monthly formulations (like Amgen's MariTide) are improving patient acceptance.
Oral (~10% of revenue, fastest growing)
The oral peptide segment is growing at a CAGR of approximately 6%. Key developments:
- Oral semaglutide (Rybelsus for diabetes, Wegovy pill for obesity)
- Orforglipron (oral non-peptide GLP-1 agonist, pending FDA approval)
- Icotrokinra (J&J's oral targeted peptide for psoriasis, submitted to FDA in 2025)
Among the roughly 102 FDA-approved peptide drugs, only 11 are oral — a gap that represents both a limitation and an opportunity.

CordenPharma CEO Dr. Michael Quirmbach stated flatly that "there is a clear shortage of manufacturing capacity globally" for peptides. That shortage is the primary reason CDMOs are investing at unprecedented levels.
Challenges and Headwinds
Pricing Pressure
Government negotiations (the TrumpRx deal), insurance company pushback, and generic competition in international markets are all compressing GLP-1 drug prices. Novo Nordisk cut U.S. list prices by up to 70%. Lower prices expand the patient pool but may slow revenue growth.
Patent Cliffs
Semaglutide patent expirations in Canada, India, China, and Brazil in 2026 will introduce generic competition in markets covering roughly one-third of the global obese population. U.S. and European patents extend to 2031, providing a longer runway in the highest-revenue markets.
Manufacturing Complexity
Peptide manufacturing is technically demanding. Solid-phase peptide synthesis (SPPS) is expensive and difficult to scale. Purity requirements are stringent. The manufacturing complexity of GLP-1 drugs naturally limits competition — Eli Lilly alone has invested $18 billion in manufacturing infrastructure since 2020.
Regulatory Uncertainty
The FDA's crackdown on peptide compounding has restricted patient access to compounded alternatives while funneling demand toward branded drugs. Ongoing legal battles between compounding pharmacies and regulators create uncertainty for patients and providers.
Safety Monitoring
While GLP-1 drugs have strong safety profiles, the class is under ongoing scrutiny for potential concerns including gastrointestinal side effects, muscle mass loss, and theoretical cancer risk (thyroid C-cell tumors observed in rodent studies but not replicated in human data).
FAQ

Yes. Peptide manufacturing via SPPS is one of the most expensive production processes in pharma. High purity requirements, complex chemistry, and limited global capacity contribute to high costs. This is why peptide CDMO investment is surging and why manufacturing capability is a competitive moat.
The Bottom Line
The peptide therapeutics market has transformed from a specialized pharmaceutical niche into one of the largest and fastest-growing segments in global healthcare. GLP-1 receptor agonists — semaglutide and tirzepatide in particular — are responsible for much of that transformation, but the growth extends well beyond metabolic disease.
With over 170 peptide drugs in clinical trials, a CDMO sector investing billions in new capacity, and oral delivery technology opening peptides to patients who refused injections, the structural growth drivers are in place for sustained expansion through the 2030s. The conservative projection of $80-90 billion by the mid-2030s implies the market will roughly double from its 2025 level. If GLP-1 indications continue expanding and oral formulations reach their projected potential, the actual figure could be substantially higher.
For anyone watching the pharmaceutical industry, peptide therapeutics are where the growth is. And the growth is just getting started.
