Pacific Biosciences vs Illumina
Side-by-side comparison of AI visibility scores, market position, and capabilities
Pioneer of single-molecule real-time (SMRT) long-read sequencing; Revio system targets clinical and research markets. Guides to $150–$170M FY2025 revenue with 40%+ gross margins.
About
Pacific Biosciences (PacBio) was founded in 2004 in Menlo Park, California and pioneered single-molecule real-time (SMRT) sequencing technology, enabling long-read DNA sequencing that can span tens of thousands of base pairs per read. This capability is essential for resolving complex genomic regions—structural variants, repeat expansions, methylation patterns, and full-length transcripts—that short-read platforms like Illumina cannot accurately assemble.\n\nPacBio's Revio system, launched in 2023, offers a dramatic improvement in throughput and cost efficiency over prior instruments, targeting both research and clinical sequencing laboratories. Key applications include rare disease diagnosis, pharmacogenomics, plant and animal genomics, and clinical oncology. The company guides to $150–$170 million in FY2025 revenue with gross margins exceeding 40% and a path to cash flow breakeven by 2027.\n\nPacBio competes primarily with Oxford Nanopore Technologies in the long-read segment, together driving adoption of long-read sequencing for comprehensive genome assembly and clinical applications. The company is expanding its high-accuracy (HiFi) chemistry and developing Onso, a short-read system, to capture a broader share of the sequencing market. With approximately $260 million in cash, PacBio is well-positioned to scale its clinical business.
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.
