Oxford Nanopore Technologies vs Illumina
Side-by-side comparison of AI visibility scores, market position, and capabilities
UK nanopore sequencing pioneer with portable MinION device; £223M FY2025 revenue (+24% constant currency). Clinical revenues up 60% as sequencing moves to point-of-care.
About
Oxford Nanopore Technologies (ONT) was spun out of the University of Oxford in 2005, commercializing a radically different sequencing approach: passing DNA strands through biological nanopore proteins embedded in a membrane and detecting characteristic ionic current changes to call bases in real time. This enables ultra-long reads (megabase scale), direct RNA sequencing, and epigenetic base modification detection without prior amplification.\n\nONT's product range spans from the palm-sized MinION (the world's first portable DNA sequencer) to the high-throughput PromethION 2 Solo and PromethION 48 platforms. These instruments have enabled field sequencing for infectious disease outbreak response (COVID-19, mpox, Ebola), real-time clinical microbiology, plant pathogen surveillance, and cancer genomics. The company reported £223 million in FY2025 revenue, representing 24% constant-currency growth, with clinical revenues up 60% and biopharma revenues up 30%.\n\nONT is publicly listed on the London Stock Exchange and holds approximately £300 million in cash. While accuracy has historically lagged Illumina and PacBio, successive chemistry improvements and the Kit14 chemistry have closed the gap for many applications. The company is expanding its presence in clinical diagnostics, with regulatory filings underway in key markets, and remains the benchmark for portable, real-time, and long-read sequencing.
World's dominant DNA sequencing platform with ~80% market share; ~$4.34B FY2025 revenue. Powers clinical genomics, oncology diagnostics, and population-scale sequencing.
About
Illumina was founded in 1998 in San Diego and has grown into the undisputed leader in next-generation sequencing (NGS), with approximately 80% global market share across research and clinical applications. The company's sequencing-by-synthesis (SBS) chemistry and NovaSeq, NextSeq, and MiSeq instrument platforms have become the standard infrastructure for genomic research, clinical oncology, reproductive health, and infectious disease diagnostics worldwide.\n\nIllumina's business model combines high-margin consumable sales (flow cells, reagent kits) with instrument placements, creating a razor-and-blades recurring revenue structure. Its clinical sequencing segment showed accelerating growth in 2025, with clinical consumables revenue up 20% year-over-year in Q4. The company is expanding into spatial transcriptomics and multi-omics with new instruments unveiled at AGBT 2025, broadening its addressable market.\n\nIllumina reported $4.34 billion in FY2025 revenue and guides to $4.5–$4.6 billion for FY2026, with non-GAAP operating margins of ~23%. Having divested Grail (its liquid biopsy subsidiary) following regulatory pressure, Illumina is refocused on its core sequencing franchise and positioned to benefit from continued clinical adoption of genomic medicine.
