New data from Evident intelligence platform suggests that many of the world’s largest banks are reducing their reliance on OpenAI as their primary large language model provider.

18 months ago, OpenAI provided the underlying technology for roughly half of the banking AI use cases that disclosed vendor information. Evident’s latest analysis shows that by the end of 2025, OpenAI’s share had fallen to just one-third, with banks increasingly developing and deploying use cases built on alternative providers such as Anthropic and Google.

According to Evident’s analysis, coding is one of the few banking AI use cases where more than half of deployments demonstrate tangible return on investment. While Anthropic is consistently ranked best-in-class for code generation and review, Google has leveraged its existing cloud relationships to make enterprise deployment and system integration easier.
