Walmart signed its first nuclear power purchase agreement. Constellation is selling about 176 megawatts of carbon-free electricity from its Dresden plant in Illinois, across two 15-year terms that start in 2029 and 2030. Roughly 30 of those megawatts don't exist yet. They come from upgrading the existing reactors instead of building anything new.

I want to be clear about what this actually is, because the headline reads like an ESG announcement. It's really a supply chain decision.

Walmart is building a high-tech perishable distribution center in Belvidere, Illinois. Perishable means refrigeration, and refrigeration means the grid cannot afford to hiccup. Cold chain doesn't get a snow day. When the freezers lose power, you're not booking a rounding error; you're throwing out full truckloads and explaining empty shelves to customers. So reliability is the point, and Walmart went and secured it at the source.

Look at what the company actually locked in: price and certainty, fifteen years at a stretch, then another fifteen. Everybody in retail has spent the last three years getting surprised by costs they couldn't forecast. Energy is climbing that same list, especially now that automated distribution centers behave less like warehouses and more like small data centers that happen to store lettuce. If you can fix a large slice of your power cost out to the mid-2040s, you take that deal, and you don't think twice. Call it sustainability if you want. I'd call it margin protection.

The detail I keep coming back to is that nobody built a new plant. Constellation found 30 extra megawatts inside Dresden by running the existing asset harder and smarter, which is exactly the discipline good operators bring to a store or a warehouse. Before you spend on the shiny new thing, get more out of what you already own. Dresden already supports more than 1,100 jobs and is licensed to run for decades. The infrastructure was sitting there. Walmart showed up with a checkbook and a long memory.

Why does any of this matter to the rest of us? Because energy is quietly turning into a competitive advantage in retail. The companies that win the next decade will have a predictable cost structure feeding an operation that gets more automated and more power-hungry every year. Walmart is early here, and Walmart is rarely early by accident. When it commits to infrastructure at this scale, it has usually already run the math the rest of the industry is about to run.

So watch who follows. Kroger, Target, the big logistics providers, the hyperscalers are already sniffing around nuclear for their own data centers. They are all staring at the same question, which is how to buy reliable, emissions-free, price-stable power before it gets scarce and expensive.

Walmart bought certainty for the next fifteen years. The smart read is that certainty is about to get a lot harder to buy.

StockX wants you to believe it invented something. Peter Curran calls StockX Listings "a new business model." It isn't. It's StockX conceding that the new-sneaker resale boom has cooled, and that the money now sits in used goods and vintage apparel, exactly where eBay parked $1.2 billion buying Depop back in February.

So StockX is opening its marketplace to secondhand sneakers and old clothes, with AI that reads your photos and suggests a price. Early sellers keep 100% of the sale. Read that again. Zero fees. That's not a business model. That's a customer-acquisition subsidy, and subsidies end the minute the inventory shows up.

Here's what StockX actually gets right. Its authentication brand still means something. Bolting optional verification onto a used listing is a real edge over a random secondhand post. That's the whole pitch.

The prize is a US secondhand apparel market projected at $78.8 billion by 2030. Everybody wants it. eBay, Depop, ThredUp, and now StockX.

My question is simpler than any of the press releases. When the zero-fee window closes, does the sneaker crowd stay to sell their old flannels? I doubt it.
