Genetic sequencing companies are the engines underpinning the field of genomics and are a critical component of genetic research and testing. Advancements in technology are making sequencing cheaper, faster, and more accurate.
Sequencing volumes continue to increase in research and are growing rapidly in clinical applications, with the key drivers including whole-genome sequencing, cancer testing, and recurrence monitoring. Genetic sequencing stocks are shares in companies that use genetic sequencing technology to analyze DNA.
The global genetic sequencing market is projected to grow to roughly $92 billion by 2033. Meanwhile, ARK Investment Management estimates sequencing costs will continue to decline sharply. Falling costs are a critical aspect of opening up new markets and uses.
Top genetic sequencing stocks to consider
These are some of the leading pure-play genetic sequencing companies:
| Name and ticker | Market cap | Dividend yield | Industry |
|---|---|---|---|
| Illumina (NASDAQ:ILMN) | $19.0 billion | 0.00% | Life Sciences Tools and Services |
| Pacific Biosciences Of California (NASDAQ:PACB) | $419.8 million | 0.00% | Life Sciences Tools and Services |
| 10x Genomics (NASDAQ:TXG) | $2.7 billion | 0.00% | Life Sciences Tools and Services |
| Oxford Nanopore Technologies Plc (OTC:ONTTF) | $1.7 billion | 0.00% | Life Sciences Tools and Services |
1. Illumina
Since its 1998 founding, Illumina (ILMN -1.88%) has become an industry leader with roughly 80% of the global sequencing market and an installed base of more than 22,000 sequencing systems.

NASDAQ: ILMN
Key Data Points
Human DNA contains 3.05 billion base pairs. Illumina gained its dominant market position by championing short-read sequencing technology, which breaks DNA into short segments to aid in analysis for genetic research. As the sequencing market expands from research to clinical applications, Illumina is developing tools to help physicians diagnose and select treatments for patients.
The desire to play a larger role in clinical testing led Illumina to make a controversial move in August 2021: It completed the $8 billion acquisition of cancer testing company Grail despite an ongoing European Commission review over monopoly concerns. Illumunia ultimately spun off Grail as a separate entity in 2024.
The company believes it still has a significant growth opportunity, with increasing demand for oncology therapy selection and minimal residual disease detection, as well as a broader adoption of whole genome sequencing. Illumina estimates its total addressable market tops $100 billion in the clinical arena, plus more than $25 billion in research settings.
2. Pacific Biosciences of California
Pacific Biosciences of California (PACB -1.08%), also known as PacBio, is pioneering long-read sequencing technology, which uses longer DNA segments to map the whole genome.

NASDAQ: PACB
Key Data Points
Long-read sequencing can uncover parts of the genome missed by short-read sequencing. Although the Human Genome Project was declared complete in 2003, it missed about 8% of the genome. PacBio highlighted the benefits of its HiFi whole-genome sequencing technology by helping scientists fill in the remaining 8%.
Illumina tried to acquire PacBio in 2018. However, the Federal Trade Commission opposed the deal. The two companies agreed to terminate their merger agreement in early 2020.
PacBio continues to challenge its much bigger rival. Its latest technology, the Revio sequencing platform, is the fastest-growing platform in its history. Like Illumina, it sees major growth opportunities, especially in cancer genomics.
Unlike Illumina, though, PacBio isn't profitable. The company is working to improve efficiency, reduce costs, and lower its cash burn.
3. 10x Genomics
10x Genomics (TXG -1.12%) was founded in 2012 to "build solutions for scientific discovery that reveal and address the true complexities of biology and disease." The company manufactures instruments, consumables, and software for whole-genome sequencing, exome sequencing, and single-cell transcriptomics.

NASDAQ: TXG
Key Data Points
The Chromium platform developed by 10x Genomics is the "gold standard" in single-cell genomic analysis. The company has sold more than 6,400 Chromium systems.
It's also a leader in spatial transcriptomics, which involves analyzing a whole transcriptome (the complete set of RNA in a cell) or targeted gene expression mapped to specific locations in tissue. 10x refers to spatial analysis as understanding "how all the parts fit together" at the cellular level. It markets two spatial systems: Visium and Xenium.
The company estimates its serviceable addressable market today stands at around $13 billion, with $6 billion of the total in single-cell and $7 billion in spatial. 10x has captured only a sliver of that market, though, with 2024 revenue of $610.8 million.
4. Oxford Nanopore Technologies
Oxford Nanopore Technologies (OTC:ONTT.F) was founded in 2005 by scientists conducting research at the University of Oxford in England. Its focus from the beginning was on nanopore gene sequencing, where DNA is passed through a membrane with tiny holes called nanopores.

OTC: ONTTF
Key Data Points
The company competes against Illumina and PacBio. One key competitive advantage it offers is that it markets the only sequencing technology that supports real-time analysis.
Although Oxford Nanopore's market share remains relatively small, over the last five years, its revenue has increased by a compound annual growth rate of 28%. The company makes around 70% of its revenue from consumable sales.
Oxford Nanopore's shares aren't listed on any U.S. stock exchanges. However, U.S. investors can buy the stock on over-the-counter (OTC) markets.
Investing in genetic sequencing stocks
Mapping the human genome once took 13 years and $2.7 billion. Today, next-generation sequencing (NGS) can decode a full genome in a day for under $600. That rapid drop in cost and time has opened the door to wider research, clinical, and commercial use -- and to new investing opportunities.
Sequencing companies use different technologies to read DNA. Short-read sequencing is fast and cost-efficient, while long-read sequencing captures larger DNA segments that help analyze complex genetic regions. Ongoing improvements in chemistry, throughput, and cost are driving hybrid systems that combine both approaches.
Most sequencing companies operate on a “razor-and-blade” model:
- Instruments (the razors) help lock in customers
- Consumables (the blades), such as reagents, kits, and flow cells, often make up 50%+ of revenue
- Services (data analysis, workflow support) add recurring value and typically contribute 10%+ of revenue
As with many technology companies, investors can directly measure and monitor the progress of sequencing companies against specific levers of performance. Examples include:
- Number and type of instruments being placed or under development
- Growth in customers and partners using the instruments and consumables
- Level of penetration into research and clinical markets
- Efforts to lower price points to open new uses and markets
- Product development and mergers and acquisitions (M&A) to expand testing approaches
How to choose the right genetic sequencing stocks
When choosing genetic sequencing stocks, the same fundamentals that matter in other industries still apply. Investors should look at market share trends, revenue growth, profitability, and cash flow. A strong patent portfolio can provide a meaningful competitive moat in this space. Valuation also matters, and some investors use the PEG ratio to judge whether a stock’s price is justified by its growth prospects.

Future of genetic sequencing
Genetic sequencing technology is advancing rapidly. The future of genetic sequencing is likely to reflect several key trends, including:
- Increased integration with artificial intelligence (AI)
- A shift from episodic diagnoses to regular health monitoring using liquid biopsies (lab tests that detect cancer in the blood or other bodily fluids)
- Increased adoption of portable genetic sequencing systems
- Use of hybrid systems that incorporate both short-read and long-read sequencing
It's been more than 20 years since the completion of the Human Genome Project. However, we are in the early innings of a genomic revolution that could create many companies with multibillion-dollar market capitalizations. This won't happen overnight, but for patient buy-and-hold investors, genetic sequencing company stocks could be a healthy addition to a portfolio.
