Banks Reduce Reliance on OpenAI

Why It Matters

The decline signals a potential loss of OpenAI’s enterprise foothold, reshaping competitive dynamics in the financial‑services AI market.

Key Takeaways

• OpenAI share fell from 50% to 33% among banks.
• Anthropic leads in code generation ROI for banking.
• Google leverages cloud ties for easier integration.
• Banks favor model‑agnostic strategies, diversifying vendors.
• BBVA, Morgan Stanley remain OpenAI partners.

Pulse Analysis

The banking sector has long been a testing ground for generative AI, and recent evidence from Evident’s AI Index confirms a measurable pivot away from OpenAI’s large‑language models. Eighteen months ago, roughly half of disclosed banking AI projects cited OpenAI as the underlying provider; the latest tracker projects that figure to dip to one‑third by the close of 2025. This contraction reflects a broader enterprise trend toward vendor diversification, as financial institutions seek to mitigate risk, control costs, and tap specialized capabilities offered by emerging competitors.

Two use‑cases illustrate why banks are widening their AI portfolio. Coding assistance, the only category where more than half of deployments report clear ROI, has become a showcase for Anthropic, whose models consistently outperform rivals in code generation and review. Meanwhile, Google’s Gemini Enterprise benefits from deep integration with existing cloud contracts, simplifying deployment and system‑level security compliance. The shift also mirrors a growing preference for model‑agnostic architectures, allowing banks to swap providers without re‑engineering core applications, thereby preserving flexibility as regulatory and performance demands evolve.

The retreat does not spell an immediate end to OpenAI’s banking presence; firms such as BBVA and Morgan Stanley continue to run mission‑critical workloads on its models. However, the erosion of market share signals heightened competition and may force OpenAI to accelerate its enterprise‑grade offerings, pricing structures, and compliance tooling. For investors and technology strategists, the trend underscores the importance of monitoring vendor diversification metrics, as the balance of power among OpenAI, Anthropic, Google, and emerging niche players will shape the next wave of AI‑driven financial services.
