Oligonucleotide synthesis is a laboratory process used to create short sequences of DNA or RNA. These sequences are used in applications such as PCR, DNA sequencing, genetic testing, gene expression analysis, and drug development, as well as in gene modification, molecular diagnostics, and the development of nucleic acid based drugs. According to Polaris Market Research, the oligonucleotide synthesis market was valued at USD 3.55 billion in 2025, is estimated at USD 4.07 billion in 2026, and is projected to reach USD 12.49 billion by 2034, exhibiting a CAGR of 15.01% from 2026 to 2034. This article reviews the product, application, and end-user segments that give the market its commercial shape.

Services Lead the Product Mix

By product, the market is segmented into synthesized oligonucleotide products, equipment, reagents, and services. The services segment accounted for 38.24% of market revenue in 2025, making it the largest product segment. The report explains that it includes custom oligonucleotide synthesis, purification, modification, and related laboratory services. Many pharmaceutical, biotechnology, and research organizations use these services to avoid investing in specialized equipment and in-house production systems.

Growing demand for customized DNA and RNA sequences supports the use of outsourcing across research, diagnostics, and therapeutic development. For service providers, custom oligonucleotide synthesis is therefore a core commercial offering, and Polaris notes that more companies are outsourcing synthesis, purification, and other services. The synthesized oligonucleotide products segment is projected to grow at a CAGR of 15.14% during 2026–2034, attributed to the increased prevalence of genomic studies, including gene expression analysis and genetic testing, and to the introduction of biochips (DNA chips) for simultaneous analysis of multiple clinical samples.

PCR Primers Anchor Application Demand

By application, the market includes PCR assays and panels, PCR primers, DNA microarrays, sequencing, antisense oligonucleotides, fluorescence in situ hybridization (FISH), and others. In 2025, the PCR primers segment accounted for 20.4% of market revenue, making it the leading application. The report notes that primers are the most extensively employed oligonucleotide in Polymerase Chain Reaction, and that their adoption in gene sequencing experiments is notable, driven by their utility in fluorescent detection and target amplification.

As PCR technology has advanced into RT-PCR, qPCR, and digital PCR, PCR primers have adapted accordingly, and specially designed PCR assays and panels for detecting and measuring gene expression underscore their role. Thermo Fisher Scientific, for example, offers custom DNA oligo synthesis for applications including cloning, sequencing, PCR, and gene detection.

Genetic Testing and Diagnostic Use Cases

Polaris identifies a range of use cases for oligonucleotides, including PCR testing and molecular diagnostics, cancer biomarker detection, gene expression analysis, CRISPR gene editing, drug discovery, rare disease research, infectious disease testing, and RNA therapeutic development. In diagnostics, primers and probes help amplify and detect specific genetic targets, and sequence-specific probes help identify genetic and molecular biomarkers.

Rising awareness and understanding of genetic disorders is also fueling demand for oligonucleotides in diagnostics and potential therapeutic interventions. In Asia Pacific, the growing demand for genetic testing, molecular diagnostics, and advanced therapies is creating new opportunities for oligonucleotide synthesis providers, and Europe is also seeing increasing use of molecular diagnostics and genetic testing.

Antisense Oligonucleotides and Therapeutic Research

The antisense oligonucleotides segment is projected to grow at a CAGR of 15.9% during 2026–2034. Rising research into targeted therapies and gene-modulation treatments is supporting demand, along with increasing interest in cancer, cardiovascular, and rare disease research. According to the report, these molecules are used to regulate gene expression and study disease pathways. The report also points to the escalating use of antisense oligonucleotides in clinical trials addressing conditions such as cancer, cardiac disorders, and ocular dysfunctions.

End Users and Regional Demand

By end user, the market covers pharmaceutical and biotechnology companies, academic & research institutes, diagnostic laboratories, contract research organizations, and hospitals and clinical laboratories. Academic & research institutes accounted for 44.9% of market revenue in 2025, making them the largest end-user segment, as they use oligonucleotides for PCR, sequencing, gene editing, and other molecular research applications.

North America dominated the market with 40.9% of revenue in 2025, supported by its prominent pharmaceutical and biotechnology sector, substantial research and development investment, and a surge in genomic studies and gene therapy initiatives. Asia Pacific is expected to grow fastest, at a CAGR of 17.5%, as investment in biotechnology, genomics research, and personalized medicine rises, with China, Japan, and India seeing increased research and business activity.

Key Players

Major players include Agilent Technologies, Ansa Biotechnologies, ATDBio Ltd., Azenta Life Sciences (GENEWIZ), Bio-Synthesis, Eurofins Genomics, GenScript Biotech Corporation, Integrated DNA Technologies (IDT), LGC Biosearch Technologies, Merck KGaA, Nitto Denko Avecia, Thermo Fisher Scientific, TriLink BioTechnologies, and Twist Bioscience Corporation. Thermo Fisher provides custom DNA and RNA oligonucleotide synthesis for research, diagnostics, and therapeutic applications, including large-scale and GMP manufacturing and custom modifications. The report describes the market as fragmented, with companies focusing on partnerships, product upgrades, and collaboration.

Conclusion

The oligonucleotide synthesis market is built on services, essential molecular tools, and expanding diagnostic and therapeutic research. With USD 3.55 billion in 2025 and a projected USD 12.49 billion by 2034 at a 15.01% CAGR, the sector offers clear opportunities for providers that combine customization with quality.
