Oral Semaglutide’s Market Potential and Strategic Implications for Diabetes and Obesity Treatment

The GLP-1 therapeutics market is on the cusp of a transformative phase, driven by the rapid adoption of oral formulations and expanding indications for diabetes and obesity treatment. With the global GLP-1 receptor agonist market valued at $53.5 billion in 2024 and projected to surge to $268.4 billion by 2034 [2], the introduction of needle-free alternatives like Novo Nordisk’s oral semaglutide and Eli Lilly’s orforglipron is poised to redefine patient access and market dynamics. These innovations not only address unmet needs in weight management but also signal a strategic shift in how pharmaceutical companies compete in a high-stakes therapeutic area.

Market Growth and Innovation Drivers

The GLP-1 agonist segment for weight loss alone is expected to grow from $13.84 billion in 2024 to $48.84 billion by 2030, fueled by rising obesity prevalence and the drugs’ efficacy in reducing cardiovascular risk [4]. Oral semaglutide, in particular, has demonstrated a 16.6% average weight loss in clinical trials, outperforming Eli Lilly’s 12.4% result [1]. This clinical edge, combined with Novo Nordisk’s $6.5 billion investment in U.S. manufacturing capacity [4], positions the company to dominate the emerging oral GLP-1 market. Analysts project Novo’s oral semaglutide to capture a 21% share of the 2030 global daily oral weight loss drug market ($4 billion), while Eli Lilly’s orforglipron is forecasted to secure 60% ($13.6 billion) [1].

Strategic Implications for Pharma Innovation

The approval of oral semaglutide by the FDA in late 2025 [2] marks a pivotal moment in pharma innovation. Unlike injectable formulations, oral delivery eliminates barriers to adoption, particularly among patients averse to needles. Novo Nordisk’s OASIS-4 trial, which showed a 13.6% mean weight loss over 64 weeks [2], underscores the drug’s potential to become a first-line treatment for obesity and cardiovascular risk reduction. Meanwhile, Eli Lilly’s orforglipron, while trailing in weight loss metrics, may gain traction through lower pricing and easier manufacturing [1].

The competitive landscape is further complicated by emerging players in China and the anticipated entry of 1-2 new GLP-1 drugs annually starting in 2026 [2]. However, Novo Nordisk’s aggressive R&D pipeline—including the STEP UP trial’s 7.2 mg semaglutide formulation, which achieved 20.7% weight loss [3]—and its recent FDA approval for semaglutide in treating metabolic dysfunction-associated steatohepatitis (MASH) [3] solidify its leadership. These moves highlight the company’s strategy to diversify therapeutic applications and mitigate generic competition.

Risks and Opportunities

Despite its strengths, Novo Nordisk faces challenges, including supply constraints and regulatory scrutiny. However, its $6.5 billion U.S. investment in 2025 [4] ensures manufacturing readiness, a critical advantage over competitors. For Eli Lilly, the lower efficacy of orforglipron could limit market share unless pricing or formulation advantages offset this gap. Investors should also monitor the impact of generic GLP-1 entrants and potential licensing agreements, which could reshape the market [2].

Conclusion

Oral semaglutide represents a paradigm shift in GLP-1 therapeutics, combining clinical efficacy with patient-friendly delivery. As the market expands, Novo Nordisk’s strategic investments and Eli Lilly’s competitive innovations will define the next chapter of obesity and diabetes treatment. For investors, the key lies in balancing clinical differentiation, manufacturing scalability, and regulatory milestones to capitalize on a sector projected to grow at a 17.5% CAGR through 2034 [2].
