The market is experiencing growth driven by increasing demand for small molecule drugs, increasing outsourcing trends among pharmaceutical companies and surge in number of clinical trials.

Small molecules continue to play an important role in developing new treatments globally. Specialty medicines are driving global pharmaceutical growth, particularly in developed markets, with small molecule applications accounting for over half of specialty sales. According to the U.S. FDA, 46 novel drugs were approved in 2025, including therapies targeting advanced cancers and rare diseases, while 1 novel drug has been approved so far in 2026. Moreover, according to an article published by the American Chemical Society in January 2024, the U.S. FDA approved 50 new drugs in 2024, marking a notable increase from the 37 approvals in 2022. Thus, small molecule drugs continue to dominate the pharmaceutical industry’s drug development pipeline. As pharmaceutical companies focus on developing new small molecule drugs to address various medical needs, they require the services of API CDMOs to manufacture these active ingredients efficiently and cost-effectively.

Furthermore, pharmaceutical companies have been outsourcing small-molecule API production to CDMOs to enhance efficiency, control costs, and accelerate time-to-market. In addition, rising R&D expenses, complex regulatory requirements, and the need for resilient supply chains drive this shift. CDMOs provide specialized expertise, advanced infrastructure, and scalable manufacturing without heavy capital investment, reducing financial and operational risks. Besides this, long-term partnerships also support innovation and global market access. For instance, in August 2025, the U.S. FDA launched FDA PreCheck to strengthen domestic supply chains, as most APIs are sourced overseas and only 11% are U.S.-based. Thus, growing utilization of CDMOs in the pharmaceutical sector stems from various reasons, with cost-effectiveness as the prominent factor.

Moreover, the surge in clinical trials globally is fueling demand for small-molecule APIs, driving growth in the CDMO market. As pharmaceutical and biotech companies advance more compounds into preclinical and clinical stages, the need for reliable, scalable API production has intensified. In addition, outsourcing to CDMOs enables firms to meet this growing demand efficiently, leveraging specialized expertise, flexible manufacturing capacity, and regulatory compliance. This trend enables companies to accelerate development timelines and bring novel therapies to market more quickly. Similarly, as of February 2024, the global count of registered clinical trials on ClinicalTrials.gov is 483,592, reflecting a noteworthy increase compared to the reported over 365,000 registered trials in early 2021. Among the current number, 66,206 trials actively recruit participants. This expansion underscores the continual growth of the clinical research landscape. Several factors contribute to the rise in registered studies, including advancements in medical technology, an upsurge in diseases under investigation, and the imperative for novel treatments.
