The Second Reading

On last week's earnings call, Walmart's CEO John Furner shared two numbers about Sparky, the AI shopping assistant inside the Walmart app: the number of customers using it is up 70 percent from last year, and customers who shop with it spend 40 percent more per order than those who do not. The sharper fact is that this is the second time in six months Walmart has put a Sparky number in front of investors, and the premium held while the user base grew.

This episode is about the difference between an AI claim and an AI metric, why the most useful AI numbers live in earnings-call transcripts rather than press releases, and the one question worth carrying into your next board meeting.

In this episode, Stephen Forte covers:

• The two numbers from Walmart's Q2 FY2027 call (August 20, 2026): Sparky users up 70 percent year over year, and Sparky shoppers spending 40 percent more per order. Plus the meal-plan story that shows what the assistant actually does, including checking what the customer already bought so it does not sell them something twice.
• The February reading: on the Q4 FY2026 call, Sparky shoppers showed roughly 35 percent higher order value. Why a premium that holds while the crowd arrives is the opposite of how early-adopter premiums usually behave.
• The honest caution: correlation is not causation. Loyal customers self-select into new features, and Walmart's own careful phrasing ("more than others who do not") is a comparison, not a causal claim. That care is worth something.
• The detail that turns this into a story about every company: Walmart's press release says nothing about any of it. The release is the version compliance approved; the call is the version the operator believes.
• Why a revenue-side AI number (bigger baskets, more customers choosing the assistant) is a different strategic object than the usual cost-side claims.
• Two habits to steal: reading competitors' earnings-call transcripts instead of their press releases, and picking your own "Sparky number," the one AI metric you would report twice, six months apart, without knowing whether the second reading flatters you.
