Majority of bank LLM pilots fail to reach production; ROI case remains unproven

Industry data shows ~73% of large-bank LLM proofs-of-concept stall before deployment due to model hallucination, data quality, compliance friction, and weak ROI metrics. Pilot-to-production gap signals maturity challenge.

WHY IT MATTERS

For risk and compliance teams: high failure rate justifies skepticism of vendor hype and internal timelines. Invest in eval frameworks and data governance now; assume 18–24 month runway before live models on regulated workloads.
