Insights · Weekly recap

The rails under merchant payments are being rebuilt.

Every Monday, one page: what moved last week in card costs, payment rails and AI agents, and what it means for the business behind the counter.

Weekly recap · No. 1 · Sep 14 – 20, 2026 · Published Mon, Sep 21

AI agents started picking up the phone to book for people.

A week after Meta launched Muse, Instinct and Meta began letting their agents call businesses for reservations and appointments. Circle opened its Arc network with Visa and Mastercard among the founding validators. Retailers kept fighting the Visa–Mastercard settlement, and UK banks started funding a possible domestic alternative to the card networks.

Cost line

Merchants and banks look for a way around card pricing.

What getting paid costs

  • Sep 14

    Britain's largest banks start a roughly £50 million fundraise for the UK Payments Delivery Company. It could eventually become a domestic alternative to Visa and Mastercard.Source: Constantine Cannon (citing Law360 and Sky News)

  • Sep 15

    Walmart and major retail groups press their objections to the Visa–Mastercard swipe-fee settlement in New York federal court. They want the class decertified or the right to opt out.Source: Constantine Cannon (citing Law360 and Sky News)

At the counter: Walmart and the big retail groups have said they would rather go to trial than accept a 0.1-point cut. Small merchants don't have that option.Source: Shopappy · PYMNTS

Our take

The pressure on card pricing is coming from both sides of the Atlantic at once.

Rails line

The card networks help run a stablecoin network.

Digital dollars reach checkout

  • Sep 16

    Circle opens its Arc network to the public. Visa, Mastercard, BlackRock, DTCC and ICE are among its 11 founding validators, which join in phases. Fees are paid in USDC and transactions settle in under a second.Source: The Block

At the counter: sub-second finality means a payment is final before the receipt prints.Source: The Block

Our take

When Visa and Mastercard help validate a stablecoin network, the question is no longer whether these rails are real.

Agent line

Agents call the businesses that have no other way in.

    Instinct launches Concierge in early access. Its agent phones businesses for restaurant reservations, dentist cancellation lists and billing issues. The same day, Meta expands Muse's outbound-calling beta to U.S. businesses for selected users.Source: Let's Data Science

At the counter: the phone at the host stand may already be ringing with an agent on the other end.Source: Let's Data Science

Our take

When an agent has to phone a business, the business has no better way in.
