Synthetic data is moving from “nice-to-have” to default infrastructure for AI teams—pushed by privacy constraints and data scarcity. But the same shift is surfacing an uncomfortable reality: synthetic at scale can quietly degrade model quality if governance and evaluation lag.
Synthetic Test Data for Artificial Intelligence (AI) Research Report 2025: $8.24 Bn Market Opportunities, Trends, Competitive Analysis, Strategies and Forecasts 2019-2024, 2024-2029F, 2034F
A GlobeNewswire-distributed market research report projects rapid growth in the synthetic test data for AI market, estimating expansion from $1.81 billion in 2024 to $2.46 billion in 2025—a 35.7% CAGR. The report frames synthetic data as a response to both model complexity and tighter constraints on using real personal data in development and testing.
It highlights trends including increased adoption of AI-generated synthetic data, growth in privacy-preserving data generation methods, and rising demand for regulatory-compliant synthetic data solutions—signaling that buyers are increasingly looking for “synthetic + governance,” not just faster dataset creation.
- Budget shift is underway: Synthetic test data is being treated as core AI infrastructure (not an experiment), which will pull spend toward platforms, pipelines, and validation tooling.
- Compliance is becoming a product requirement: “Regulatory-compliant synthetic data solutions” implies procurement will increasingly ask for auditable controls, documentation, and risk assessments—not just utility metrics.
- Privacy-preserving methods are a differentiator: Teams should expect more scrutiny on how synthetic data is generated (and whether it can leak or memorize), not only whether it “looks real.”
Tech companies are turning to 'synthetic data' to train AI models
TechXplore reports on a widening industry shift toward synthetic data generation as companies run into limits on available real-world training data. The piece outlines why synthetic data is attractive—speed, scale, and fewer direct dependencies on sensitive or proprietary sources—while also emphasizing that synthetic-heavy training pipelines introduce failure modes that teams can miss until late.
Key risks flagged include “model collapse” and increased hallucinations when models are trained on too much AI-generated content, especially if the synthetic data lacks diversity or compounds existing biases and errors. The article positions synthetic data as a tool that can help, but one that requires disciplined management—often via hybrid approaches that retain high-quality real data where it matters most.
- Quality governance becomes non-optional: As synthetic volumes grow, teams need explicit acceptance criteria (coverage, diversity, error bounds) and monitoring to prevent silent regression.
- Hybrid data strategies will win: The practical path is often synthetic for scale plus curated real-world anchors for calibration, evaluation, and edge-case grounding.
- Transparency affects trust: If synthetic data is used in training, internal stakeholders (risk, legal, product) will increasingly expect traceability: what was synthetic, how it was generated, and how it was validated.
