Big River Services certainly looks like a significant online merchant, with its sales of around $1 million a year through e-commerce marketplaces including Walmart, Shopify, eBay and Amazon. What the business doesn’t disclose on its website is that Big River is an arm of Amazon that surreptitiously gathers intelligence on the e-commerce leader’s competitors. The WSJ’s Dana Mattioli and Sarah Nassauer report the clandestine operation works under a plan called “Project Curiosity” that uses its sales to get pricing data, logistics information and other details about rival marketplaces. Team members have attended their rivals’ seller conferences and met with competitors identifying themselves as employees of Big River, instead of disclosing that they worked for Amazon. The shell company has bought inventory and found warehouses in the U.S., Germany, England, India and Japan so they could pose as sellers on competitors’ websites.

To get information about rival logistics services, Big River stored inventory with companies including FedEx. United Parcel Service, DHL, Deliverr and German logistics company Linther Spedition. The biggest win for Big River may have come when it finally got onto Walmart’s website, where one of its product names was listed this month as a “Pro Seller” – a top performing merchant. An Amazon spokeswoman said the company uses the common business practice of benchmarking against other companies’ services and performance “in order to improve their experiences working with us.”

China’s epic property bust has saddled its steelmakers with a glut of unsold metal, and countries around the world are feeling the impact. President Biden’s announcement that he will seek to triple a key tariff rate on imports of Chinese steel highlighted a problem that is rolling across industrial countries as China’s output grows. The WSJ’s Jason Douglas reports that exports of Chinese steel have risen 33% in the past year as the country’s enormous producers try to unload their wares abroad now that construction at home has dried up. U.S. imports of Chinese steel have fallen since Trump-era tariffs came into effect, but the products are landing in countries including Brazil, Vietnam, India, the U.K., the Philippines and Turkey. All of those have antidumping investigations under way. With China’s real-estate market struggling, steel producers can expect to sit on unsold metal for years unless they rein in production.
