Which large banks are the leaders in AI? (2026 ranking)

How do the large banks rank on AI?

The 25 highest of the 123 banks that disclose an AI programme, scored with the AI-index formula across all 140 profiles. Columns: score (and the bank's rank on the US-only index), AI use cases in production of those described, the named platform, and independent reporting against all sources on the bank's page.

Each row quotes the bank's page on this site; the bank link opens the full record with every source. “Not disclosed” means the page records nothing on that point. Banks absent from the table have no evidence on this topic on their page.

Which banks lead in AI within each size tier?

The same ranking read within four tiers: US banks over $500bn in assets, $100bn to $500bn, under $100bn, and the non-US groups. Tier by Federal Reserve consolidated assets; non-US groups report in their own currency and are not size-ranked.

How is this ranking computed?

Score: the eight-component AI-index formula of /banks/ai-index (independent coverage 45%, use cases in production 10%, a named platform 10%, own primary disclosures 10%, dated moves in the last twelve months 10%, disclosed numbers 5%, named leaders 5%, use cases described 5%), with each component as the bank's percentile rank among all 140 profiled banks rather than the 120 US banks. The US index rank is shown for reference and can differ by a few places.

Banks whose page records that they have disclosed no AI programme are excluded. Ties: assets, then name. Date: the latest dated move on the bank's page.

What are the caveats?

The score measures the depth of the public record, not capability: a bank that builds quietly ranks below one that publishes. Independent coverage carries the most weight, so a bank covered widely by the trade press rises even when its own disclosures are short.

Use-case counts are of distinct systems described on the bank's page, each with a source; a bank may run more than it has described.

How does this differ from the AI index?

The AI index ranks the 120 US banks only; this page applies the same formula to all 140 profiles, including the 20 non-US groups, and shows production use cases and the named platform beside the score. The AI index and its method are on their own page; the technology leaders and generative AI guides are hand-written cross-bank tables with their own sourcing.
