The Financial Post reports in its Saturday edition that Amazon, the company that did more than any other to drive e-commerce adoption, has been notably more defensive than Walmart when it comes to artificial intelligence. A Financial Times dispatch to the Post says its website blocks many of the chatbots developed by start-ups and tech groups. Amazon is in talks with OpenAI about a $10-billion (U.S.) investment. That may be accompanied by some form of commercial relationship involving its marketplace, but analysts expect any agreement will be more restricted than the partnership that OpenAI and Walmart unveiled last year. Amazon boss Andy Jassy has also assured shareholders that it is "having conversations" with third party agents and expects it will partner with some of them over time. "It reminds me in some ways of the beginning of search engines," he told investors on an earnings call in October. "You had to kind of figure out the right way to work together." Amazon also said in a statement that it sees "significant opportunities to innovate and further improve the online shopping experience for customers as both an online store and agentic AI shopping assistant that shops other stores across the web."
