ARA Banking Study — Q2 2026. Brand Intelligence for the US consumer banking category, using the four frontier AI models as the customer.

329 placements · 4 models × 17 customer questions · audited banks in colour, every other institution in a stepped grey · naming variants merged before counting, including Chase and Regions, which the models name differently from their registered brand names.

Banking is a business built on branches, balance sheets and a hundred years of presence on the high street. Ask the four frontier AI models where to bank and the brand that comes back as often as Wells Fargo is Ally — which has no branches at all.

In the second quarter of 2026 we put the customer questions to ChatGPT, Claude, Gemini and Perplexity — the best bank overall, the most trustworthy, where to open a first checking account, who to use for a mortgage, which app is best, who serves gig workers — then recorded every institution they named and where it ranked.

Seventy institutions came back across 329 placements. Chase holds 10.9% of the shelf, Bank of America 8.5%, Capital One 7.9%. Then Ally at 7.0%, level with Wells Fargo and ahead of both digital challengers we audited — SoFi at 3.0% and Chime at 2.1%.

The regional banks are the story underneath. PNC, Regions, Truist and First Horizon hold 4.6% of the shelf between the four of them. First Horizon was never named by any model, on any of the seventeen questions. These are institutions with hundreds of branches and millions of customers, and on the shelf the machines are building they are rounding errors.

There is a specific reason this matters more in banking than in most categories. A regional bank's whole argument is that it is the bank for a place — and 'best regional bank' is one of the questions we asked. Being absent from the answer to that question is not a marketing problem. It is the core proposition failing to reach the place customers now ask.

What Ally demonstrates is that this is winnable without branches, without heritage, and without the largest budget in the category. It is legible: it does a small number of things, says so plainly, and is written about in those terms. That is the whole of the advantage, and it is available to any bank willing to be that specific about what it is for.
