The Default Said Yes For You

On 21 September Shopify announced agentic checkout with Meta's new personal agent, Muse, "on all Shopify stores." Shopify's own help pages show how: a setting called "Allow Shopify to manage for me" is on by default, direct checkout for Meta is activated by default for eligible stores in the US, Canada and Mexico, stores are "auto-enrolled in new agentic storefronts channels," and "if you do not wish to participate, it is your responsibility to disable the features." The same evening Amazon blocked Muse. Third-party marketing pixels do not fire on these orders. A week later Shopify opened its checkout to any browser-based agent.

This weekend edition asks who the customer is when a machine does the buying, how Meta and OpenAI get paid, what the agents weigh when they choose, and why a number-three player should be glad. It then walks one buyer, a factory manager with a failing pump, through four moves for the front of the house.

In this episode, Stephen Forte covers:

• The default. What Shopify switched on, the six clicks to switch it off, no fees for the channel, and why the store remains the seller.
• Who the customer is. Sixty-word prompts against three-and-a-half-word searches, and an agent that remembers.
• The money. Muse's ad carve-out and training opt-out, and Meta's Business Agent at $2 per million tokens, used by more than a million businesses a week.
• The shelf keeps moving. OpenAI's checkout fee and ranking language of 2025, its pullback in March, and today's ranking factors. Sponsored Agents and Google's Direct Offers.
• What agents weigh. Columbia and Yale's simulated store, a hotel study, and G2's software buyers.
• The challenger's opening. Dell passing Compaq in 2001, and why incumbents still have advantages.
• Four moves. Choose the buying occasion, give the claim a witness, make the next decision easy, follow the sale through. Then a thirty-day trial with one owner.
