Tariffs are shifting. De minimis rules are under pressure. And new enforcement could change how retailers operate overnight. If you sell across borders—through eCommerce, marketplaces, or direct—these changes don’t just impact compliance. They impact your pricing, margins, and conversion rates.

A creator flew to the United States for the World Cup, filmed himself trying a Big Gulp at Buc-ee's, and turned it into a Sonic brand deal. Multiply that by a few hundred visitors filming Walmart, Waffle House, and Tractor Supply, and you have the most fun retail story of the summer.

It is also the least important one.

Foreign fans handed American brands millions of impressions nobody paid for. That is a gift. It is not a business. A single Buc-ee's clip is unlikely to convert anyone once the tournament packs up, and one creator's Sonic deal is a nice payday, not a marketing channel. It gets worse for some of them. Half the brands going viral are regional. Buc-ee's cannot sell a Texas travel center to a fan flying home to São Paulo. Attention got cheap this month. Watch where the real money moved instead.

OpenAI spent the week pitching ChatGPT as an ad platform at Cannes. The company says roughly a fifth of queries carry commercial intent, claims more than 900M weekly users, and is reportedly chasing a $100B ad business by 2030. Take the round numbers with caution, because they come from the party that benefits from them. The logic underneath is still sound. Someone typing "best stroller for a small trunk" tells you more than a keyword ever did. Demand was never the question for OpenAI. Whether it can police minors, health claims, and regulated categories is. Google and Meta spent fifteen years learning that job. OpenAI is starting it now, in public, with lawsuits already filed.

Then there is Shopify, which had the most strategically intriguing week of anyone.

Spring Editions was not aimed at merchants. It was aimed at agents. Shopify wants its catalog to be the feed AI shopping assistants read from, and it is telling brands to tag their products accordingly or disappear from those results. It launched an agentic plan that pushes catalog data to large language models even for brands that do not run a Shopify store. And it cut Shop Pay loose, so any brand on any platform can now use it. PayPal spent years trying to be the checkout button everywhere and stalled. Shopify is attempting the same thing from a stronger starting position.

Put those moves side by side and the picture sharpens. Shopify is aggregating billions of SKUs so that when a shopping agent goes looking for a product, it asks Shopify first. Call that what it is. Shopify is aiming directly at Amazon.

Which leaves the question that connects all three stories. The World Cup proved attention can be free. OpenAI and Shopify are both betting they can own the step attention never controlled, which is the sale itself. One is selling the intent. The other is holding the inventory. Which is more important.

Walmart wants to be the ad platform, not the store. That is the real headline from Cannes.

The company folded Walmart Connect U.S., Walmart Connect International, and the newly renamed Sam's Club Connect under one banner. Sam's Club MAP is dead. The pitch is scale, solutions, and signals, which is corporate shorthand for: we see what you buy, online and in 10,000-plus stores, so trust our measurement.

Here is what matters. Walmart says global ad revenue grew 37% last quarter, and Walmart Connect U.S. grew 44% excluding VIZIO. Those are Walmart's own numbers, reported off a base it does not break out cleanly. Take the growth rate seriously. Treat the absolute size with caution until the 10-K does the talking.

The strategic logic is sound. Ad dollars carry margins that grocery never will. Every retailer with first-party data is chasing the same Amazon playbook, and Walmart has more shopping behavior than anyone outside Amazon.

The open question is whether advertisers want one connected Walmart or three specialized ones. Walmart is promising both at once. Shared technology, separate operations. That tension does not resolve in a press release.

Watch what the take rate does, not what the deck says.
