Summary:
• **Amazon is Spending a Lot of Money on AI** - Amazon announced it plans to spend $200 billion on artificial intelligence (AI) technology over the next few years. This is a huge amount of money, and some people who own Amazon stock became worried about whether this big investment would actually make the company more money in the future.
• **Stock Prices Went Down** - When investors heard about Amazon's big spending plans, many of them decided to sell their Amazon shares (pieces of ownership in the company), which caused the stock price to drop. This happens sometimes when people are unsure if a company's big plans will work out the way the company hopes.
