Overview
New York, NY – Feb 03, 2026 – The Global AI In Predictive Toxicology Market size is expected to be worth around USD 4,964.3 Million by 2033 from USD 360.1 Million in 2023, growing at a CAGR of 30.0% during the forecast period from 2024 to 2033.
The application of artificial intelligence (AI) in predictive toxicology is emerging as a transformative approach in chemical safety assessment, drug development, and regulatory science. Predictive toxicology focuses on forecasting the potential toxic effects of chemical substances before human or environmental exposure occurs. The integration of AI is enhancing the accuracy, speed, and scalability of this process.
Traditionally, toxicology assessments have relied on animal testing and laboratory-based experiments, which are time-consuming, costly, and subject to ethical constraints. AI-based predictive toxicology leverages machine learning algorithms, big data analytics, and computational modeling to analyze large datasets derived from chemical structures, biological assays, and historical toxicity records. As a result, toxicological outcomes can be predicted with improved efficiency and reduced dependency on animal models.
The basic formation of AI-driven predictive toxicology involves data collection, feature extraction, model training, and validation. Algorithms are trained on curated toxicological datasets to identify patterns and relationships between chemical properties and adverse biological effects. These models are then used to predict toxicity endpoints such as carcinogenicity, mutagenicity, organ toxicity, and environmental hazards.
The adoption of AI in predictive toxicology is being driven by increasing regulatory emphasis on alternative testing methods, rising research and development costs in pharmaceuticals and chemicals, and growing availability of high-quality toxicological data. In the long term, AI-enabled predictive toxicology is expected to support safer product development, faster regulatory decision-making, and improved risk assessment frameworks.

Emerging trends
- Regulators are formalizing “credibility” checks for AI safety models
A clear shift is being seen from “AI is allowed” to “AI must be proven reliable for a defined use.” The U.S. Food and Drug Administration issued a draft guidance (January 2025) that describes a risk-based credibility assessment framework for AI models used to support regulatory decisions on safety, effectiveness, or quality. - Regulatory-science programs are building AI models for specific toxicity endpoints
The U.S. Food and Drug Administration National Center for Toxicological Research “SafetAI” initiative is developing AI models to inform preclinical safety review before clinical trials, and it explicitly lists five focus endpoints: hepatotoxicity, carcinogenicity, mutagenicity, nephrotoxicity, and cardiotoxicity. - High-throughput “NAM” pipelines are expanding, creating more data for AI to learn from
Predictive toxicology is increasingly based on new approach methodologies (NAMs) that combine in vitro (lab) and computational models, rather than relying only on animal tests. This direction and its scientific basis are described in recent peer-reviewed literature (2024) focused on NAM-driven safety assessment. - Large, public toxicity datasets are becoming a backbone for model training and benchmarking
Tox21 reports that it has screened thousands of chemicals in ~70 high-throughput assays, covering 125+ biological processes, generating 120+ million data points. These volumes support stronger AI training, external validation, and cross-lab comparison. - More “mechanistic + interpretable” models are being favored over black boxes
A practical trend is the move toward models that do not only output a risk score, but also indicate *which biological pathway or assay signals* drove the prediction. This is strongly enabled by programs like Tox21, where Phase I alone tested 2,800 compounds in 50+ assays, and later phases expanded to 10,000+ compounds supporting pathway-based reasoning rather than single-number predictions.
Use Cases
- Early drug candidate screening to reduce late-stage safety failures
AI models are used to flag toxicity risks before expensive studies begin especially for organ-toxicity endpoints. The U.S. Food and Drug Administration SafetAI work explicitly targets 5 key endpoints (liver, kidney, heart, cancer risk, genetic mutation risk), aligning directly with common “stop/go” decisions in preclinical development. - Prioritizing chemicals for deeper testing using high-throughput signals
U.S. Environmental Protection Agency describes Tox21 screening of 10,000 environmental chemicals (the “Tox21 10K library”) using robotic high-throughput methods to identify disruption of biological pathways and prioritize what should be tested further. This is a core predictive toxicology workflow where AI ranks risk under constrained lab capacity. - Model development using open assay repositories for reproducible evidence packages
The Tox21 program states that results are made available through NIH and EPA toxicity databases, and Phase I outputs were placed into public resources such as PubChem. This supports an applied use case: building models where training and test data can be independently checked, which is important for regulated decisions. - Faster, evidence-based safety assessment using NAM + AI instead of only animal studies
A healthcare-driven use case is reducing dependence on slower animal testing by combining exposure information, mechanistic assay outputs, in vitro systems, and computational models. This NAM-based approach is described in peer-reviewed toxicology literature and is increasingly positioned for systemic safety decisions, where AI acts as the integrating layer across many signals. - Regulatory submissions and reviews that include AI-generated safety evidence (with defined context of use)
The U.S. Food and Drug Administration draft guidance (January 2025) is designed for AI that produces information intended to support regulatory decision-making, and it emphasizes a context of use (COU) and credibility evaluation. In practice, this enables use cases such as: AI-based toxicology models included in IND-enabling packages, with documented validation and controls.
Conclusion
AI-driven predictive toxicology is emerging as a foundational capability in modern chemical safety assessment, drug development, and regulatory science. By replacing slower, animal-dependent testing with data-driven, mechanistic, and scalable models, AI improves prediction accuracy while reducing cost and development timelines.
Strong market growth reflects increasing regulatory acceptance, expanding high-throughput datasets, and rising demand for early toxicity screening. The shift toward interpretable, endpoint-specific models and formally validated regulatory use further strengthens credibility.
As NAM-based pipelines and open toxicity databases expand, AI-enabled predictive toxicology is expected to play a central role in safer product development, faster regulatory decisions, and more efficient risk assessment frameworks globally.
