The Biotech Investment Landscape: 2026 Outlook
Before diving into individual companies, understanding the broader market context is essential.
Market Dynamics
Funding Environment: After the challenging 2022-2024 period, biotech financing is recovering but remains selective. Corporate venture capital from pharmaceutical giants (Novo Holdings, Lilly Ventures, Roche Ventures) has replaced traditional VC as the primary early-stage funding source. Companies with strong scientific validation, clear regulatory paths, and experienced teams continue attracting capital, while those with weaker fundamentals struggle.
M&A Activity: Large pharmaceutical companies are aggressively pursuing acquisitions to backfill patent cliffs and access innovative platforms. We’ve seen $12B for Avidity Biosciences (RNA delivery), $9B+ bidding wars for obesity assets (Metsera), and continued consolidation in gene therapy, cell therapy, and AI drug discovery. This robust M&A environment creates significant exit opportunities for successful startups.

AI-Powered Drug Discovery Platforms
The integration of artificial intelligence into drug discovery represents potentially the most transformative shift in pharmaceutical R&D since the sequencing of the human genome. These companies aren’t just using AI as a tool—they’re building entirely new paradigms for how medicines are conceived, designed, and optimized.
1. Recursion Pharmaceuticals (RXRX)
What They Do: Recursion has built what they call the Recursion Operating System (OS)—a platform combining automated wet-lab experiments, massive proprietary datasets (65+ petabytes), and machine learning models to discover and develop drugs at unprecedented scale and speed.
The Technology Deep Dive:
Recursion’s automated high-throughput laboratory in Salt Lake City runs over 2 million experiments weekly, generating one of the largest proprietary biological datasets in pharma. The company systematically perturbs cells (treating them with different compounds, genetic modifications, or environmental conditions), captures high-resolution images showing cellular responses, and uses deep learning to identify patterns invisible to human researchers.
Their large language model, LOWE (Linguistic-Optimized Wet-lab Execution), allows scientists to query the RecursionOS using natural language, identifying novel targets, generating novel compounds, and even scheduling synthesis and testing—essentially creating an AI co-scientist.
In June 2024, Recursion completed construction of BioHive-2, the largest AI supercomputer owned by any biopharma company, built in partnership with Nvidia. This computational power enables them to train increasingly sophisticated models and process their massive datasets at scale.
Clinical Pipeline Highlights:
- REC-994: Oral small molecule for cerebral cavernous malformation (CCM), a rare neurovascular disease. Phase 2 showed promising safety and efficacy trends; Phase 3 planning underway.
- REC-3964: Potential first-in-class oral therapy for C. difficile infection that targets toxin B rather than the bacteria itself. Phase 2 ALDER trial data expected Q1 2026.
- REC-4209: Novel candidate for idiopathic pulmonary fibrosis with undisclosed target. IND-enabling studies ongoing.
- REC-617: CDK7 inhibitor for oncology. Initial Phase 1/2 data showed partial response in platinum-resistant ovarian cancer patient with durable response exceeding six months.

4. Beam Therapeutics (BEAM)
What They Do: Beam pioneered base editing, a next-generation gene editing approach that makes precise single-letter changes to DNA without cutting both strands of the double helix. This dramatically reduces unwanted mutations and improves safety profiles compared to traditional CRISPR.
The Science Explained:
Traditional CRISPR-Cas9 creates double-strand breaks in DNA, triggering cellular repair mechanisms that can introduce unpredictable insertions or deletions. Base editors, invented by Beam’s scientific co-founder David Liu, use modified Cas proteins fused to deaminase enzymes that chemically convert one DNA base to another (A→G, T→C, C→T, or G→A) without cutting.
This “molecular pencil” approach offers:
- Higher precision with fewer off-target effects
- Lower risk of chromosomal rearrangements
- Ability to correct ~60% of known pathogenic point mutations
- Potentially safer profile for chronic disease applications
Clinical Pipeline:
- BEAM-101 (Sickle Cell Disease): Phase 1/2 BEACON trial showing promising results. Mid-2025 data from 17 patients demonstrated durable increases in fetal hemoglobin, reductions in sickle hemoglobin, fast engraftment, normalized hemolysis markers, and zero vaso-occlusive crises post-engraftment.
- BEAM-102 (Beta-Thalassemia): Transfusion-dependent patients; leverages similar HBG1/HBG2 promoter editing as BEAM-101
- BEAM-201 (Glycogen Storage Disease 1a): In vivo base editing targeting the liver; IND filed, Phase 1/2 initiated

5. Caribou Biosciences (CRBU)
What They Do: Caribou develops allogeneic (off-the-shelf) CAR-T cell therapies using its proprietary chRDNA (CRISPR hybrid RNA-DNA) gene editing platform. This approach aims to create universal donor cells that avoid immune rejection while maintaining therapeutic efficacy.
The Technology Innovation:
Traditional CAR-T therapies use patients’ own T cells, requiring weeks of manufacturing and costing $400K-500K+ per patient. Allogeneic CAR-T from healthy donors could:
- Reduce costs by 50-70% through economies of scale
- Provide immediate off-the-shelf availability
- Treat patients too sick to wait for autologous manufacturing
- Enable standardized quality control
The challenge: donor T cells would normally be rejected by recipients’ immune systems. Caribou uses chRDNA editing to:
- Knock out T cell receptor (TCR) genes preventing graft-versus-host disease
- Remove HLA class I molecules reducing host rejection
- Insert tumor-targeting CARs (anti-CD19, anti-BCMA)
- Potentially add additional modifications enhancing persistence and efficacy
chRDNA Advantages:
Caribou’s hybrid RNA-DNA guide molecules claim to enable:
- More complex multi-gene edits with preserved genomic integrity
- Reduced off-target effects and chromosomal damage
- Better control over editing outcomes
- Proprietary IP providing competitive differentiation
Clinical Programs:
- CB-010 (Phase 1): Anti-CD19 allogeneic CAR-T for relapsed/refractory B-cell non-Hodgkin lymphoma

What Success Looks Like: Strong response rates in Phase 1 trials, durable remissions, manageable toxicity, and partnership/financing to fund late-stage development
6. Chroma Medicine (merged into nChroma Bio)
What They Do: Rather than cutting DNA like traditional CRISPR, Chroma (now part of nChroma Bio after 2024 merger) works at the epigenetic level—modifying how genes are expressed without altering the underlying genetic sequence.
The Epigenetic Editing Paradigm:
Every cell in your body contains identical DNA, yet liver cells differ dramatically from neurons or muscle cells. Epigenetic marks—chemical modifications to DNA and histones—determine which genes are turned on or off in each cell type.
Diseases can result from incorrect epigenetic regulation even when the underlying DNA sequence is normal. Examples include:
- Cancers driven by silenced tumor suppressors
- Autoimmune diseases from inappropriately activated immune genes
- Neurological disorders from dysregulated neuronal gene expression
Chroma’s platform uses programmable DNA-binding proteins (derived from CRISPR but non-cutting) fused to enzymes that:
- Add or remove DNA methylation marks
- Modify histone proteins
- Recruit chromatin remodeling complexes
- Tune gene expression up or down rather than completely on/off
Advantages of Epigenetic vs Genetic Editing:
- Reversibility: Unlike DNA cuts, epigenetic changes can potentially be reversed if problems emerge
- Tunability: Can dial gene expression to optimal levels rather than complete knockout
- Safety: No DNA double-strand breaks means lower risk of chromosome rearrangements
- Broader Applicability: Can treat diseases where reducing (not eliminating) gene expression is therapeutic
Pipeline and Development:
Specific program details remain limited following the nChroma Bio merger (combining Chroma Medicine with Nvelops Therapeutics in 2024). The merged entity is focusing on:
- Oncology applications (silencing oncogenes, reactivating tumor suppressors)
- Genetic diseases where modulating expression is preferable to complete knockout
- Potential combination with traditional gene therapy
Why Watch in 2026:
- Epigenetic editing represents fundamentally new therapeutic modality
- Could address diseases untreatable by traditional gene editing

7. Dyne Therapeutics (DYN)
What They Do: Dyne develops FORCE (Fab Oligonucleotide conjugates Recycling Cell-to-cell Enhancer) platform linking oligonucleotides to muscle-targeting antibodies, achieving 30-100x higher muscle concentrations versus unconjugated oligos.
The Muscle-Targeting Opportunity:
Muscular dystrophies, myotonic dystrophy, and other muscle diseases affect hundreds of thousands of patients with limited treatment options. Traditional antisense oligonucleotides distribute throughout the body but achieve inadequate concentrations in muscle tissue to be therapeutically effective.
Dyne’s FORCE platform uses antibodies targeting transferrin receptor (TfR) highly expressed on muscle cells. After binding, the entire complex internalizes, the linker releases the oligonucleotide inside muscle cells, and the antibody recycles back to the surface—enabling repeated rounds of delivery.
Clinical Pipeline:
- DYNE-101 (Myotonic Dystrophy Type 1): Targets toxic CUG repeat RNA; Phase 1/2 ACHIEVE trial ongoing
- DYNE-251 (Duchenne Muscular Dystrophy): Exon-skipping therapy for patients amenable to exon 51 skipping; Phase 1/2 DELIVER trial initiated

9. Sana Biotechnology (SANA)
What They Do: Sana is building hypoimmune cell therapy platforms allowing allogeneic (off-the-shelf) cells to evade immune detection, plus in vivo delivery approaches administering therapies without ex vivo cell manipulation.
The Hypoimmune Vision:
Current allogeneic cell therapies must knock out HLA molecules (the “ID tags” immune systems use to distinguish self from foreign). This helps avoid rejection but makes cells vulnerable to natural killer (NK) cell attack (NK cells kill cells lacking proper HLA).
Sana’s hypoimmune platform engineers cells to:
- Express specific HLA molecules providing broad population coverage
- Include inhibitory signals (CD47, HLA-E) preventing NK attack
- Potentially avoid immunosuppression requirements
This could enable truly universal donor cells usable across patient populations without conditioning regimens or ongoing immunosuppression.
Pipeline Diversity:

12. Foghorn Therapeutics (FHTX)
What They Do: Foghorn develops medicines targeting the chromatin regulatory system—specifically BRM and BRG1, proteins within the BAF complex that control which genes are accessible for transcription.
The Chromatin Biology Science:
DNA doesn’t float freely in cells—it’s wrapped around histone proteins forming chromatin. This packaging determines which genes can be expressed. The BAF (BRG1/BRM-associated factor) complex remodels chromatin, making genes accessible or inaccessible.
In many cancers, BAF complex components are mutated, causing:
- Inappropriate activation of oncogenes
- Silencing of tumor suppressors
- Dependencies that make cancer cells vulnerable to BAF inhibition
Foghorn’s approach:
- Identify cancers with specific BAF mutations or dependencies
- Design small molecules selectively inhibiting BRM or BRG1
- Kill cancer cells while sparing normal cells (therapeutic window)
Clinical Pipeline:
- FHD-286 (BRM inhibitor):
- Targeting AML (acute myeloid leukemia) and other hematologic malignancies
