Anthropic just put AI inside 36 million small businesses. Amex put $300 of ChatGPT inside a card. US Bank baked a Spend Management platform into a no-fee product.

The plastic in the wallet is becoming a platform, and the next 12 months will set the order of the leaderboard.

The Operating System Just Got an Upgrade

On May 13, Anthropic flipped a switch that matters for every bank exec reading this. Claude for Small Business went live, putting enterprise-grade AI inside the tools 36 million SMBs already use every day. QuickBooks, PayPal, HubSpot, Canva, Docusign, Google Workspace, Microsoft 365. Fifteen pre-built workflows that run finance, ops, sales, marketing, HR, and service. The same week, Anthropic shipped Claude Opus 4.7 and a suite of AI agents built for the world’s largest banks.

The 36 million backbone of the US economy just got access to a back office that used to belong to the Fortune 500, and the banks that serve them got new agentic muscle on the same release schedule. The asymmetry is closing. Small businesses will move faster, hire later, decide sooner, and expect more from the partners around them. Their bar for easy just went up.

SMB owners want power that lowers their cognitive load, surfaces an insight before they ask, and adapts to a month where revenue spiked or dipped. The plastic in the wallet is becoming a platform. The card is the operating layer that runs alongside the owner’s day.

A question worth sitting with: how much of the owner’s workday does your card actually touch?

Same Gray Area, Same Move

Andrew Davidson sat down with Brian Jones, President of Merrick Bank, on the latest Little Conversation. Merrick sits in the top 20 US card issuers, serves roughly 5 million customers, and operates in the non-prime segment. The conversation maps cleanly onto this week’s theme.

Small business owners and non-prime consumers live in the same gray area. Both alternate between revolving and paying in full at rates well above the average cardholder. Both feel inflation, gas prices, and rate moves before the headlines catch up. Both reward the issuers who translate that lived reality into a product feature the owner can feel in the moment.

Balancing Mission, Scale, and Risk

BJ Brian Jones President, Merrick Bank · Mintel Little Conversation “Three months ago, when you used to pay $25 to fill up your car and now you’re paying $75, that’s going to eat through your credit line faster. We keep our sights tuned on what we’re hearing in our call centers and what we’re seeing in terms of credit line management.” Watch the full episode.

That is plastic to platform in non-prime form. The card that listens, reads the signal, and adjusts the product becomes the platform. Merrick’s edge sits in the same instinct the winning SMB issuers are coding into product right now.

A question Brian’s example raises: when the owner’s costs change overnight, what does your card actually do?

The Map of the Market

Patrick Rahlfs just released the 2026 Business Credit Card Go-To-Market Strategic Playbook. The chart below shows the share of voice picture in one frame.

Three lanes are forming in the business card market, and every issuer is choosing where to lead.

AI-Powered Ambition. Amex Business Platinum at $895 with a first-of-its-kind $300 ChatGPT Business credit. Chase Sapphire Reserve for Business at $795 with a $200 Google Workspace credit. These cards pair real productivity with a premium identity.

Simple Power. Amex Graphite Business Cash Unlimited at $250 with unlimited 2%. Chase Ink Premier at $195. Capital One Venture Business at $95 with software credits attached. The middle tier is where the largest pool of new accounts opens this year.

Defensive Cash Flow. US Bank Business Shield with 18 months of 0% APR and Spend Management built into the product. Amazon Prime Business and Amazon Business cards with flexible terms. Built for the owner reading divergent macro signals and choosing to stay light on fees and heavy on control.

The lanes look different on the surface. Underneath, each one bundles AI, software, and payment flexibility into the product so the card does more of the work. The plastic in the wallet is becoming a platform.

Two questions worth sitting with: Which lane anchors your portfolio? And when the owner’s reality shifts mid-month, what does your card actually do?

What I Expect Next

The past six months sketch the shape of the next 12 to 18 months. Three trends define where I expect Small Business Cards to go.

The card leads with data. In April, Visa retired Level 2 interchange and routed all reduced rates through the Commercial Enhanced Data Program. Product 3 status flows only to issuers and merchants delivering SKU-level transaction data in real time. Juniper projects virtual card transaction value to reach $6.8 trillion globally in 2026, with B2B accounting for 71% of it. The card now earns its keep through how well it integrates into the customer’s software stack. Real-time enhanced data is the new price of admission.

Agentic commerce moves into production. AI agents are already inside the workflow. Ramp automates transaction coding, Rho runs matching models, Amex bundles ChatGPT Business credits with the Business Platinum and Gold. The next step is software that executes payments inside pre-set rules, routes across rails, manages cash positions, and catches fraud at machine speed. The card becomes a permissioned endpoint for an agent acting on the owner’s behalf.

Software and capital converge. In January, Capital One announced its $5.15 billion acquisition of Brex. Mercury picked up conditional OCC national bank charter approval in April and raised $200 million the same week. One direction sees the largest US card issuer buying its way into SaaS-native distribution. The other sees a software-first SMB platform building a vertically integrated bank from scratch. The future winner blends capital reserves, regulatory standing, and software that runs the customer’s day.
