Trading Weekly AI News
November 3 - November 11, 2025This weekly update covers a dramatic time for technology trading and artificial intelligence investment. The week started with big concerns about whether technology companies' massive spending on AI was actually working out, leading to sharp declines in major stock prices.
Stock Market Takes a Big Hit
The biggest story was that technology stocks had their worst week in months. The Nasdaq Composite Index, which measures many tech company stocks, went down 3 percent. Some of the biggest tech companies took the hardest hits. Nvidia, which makes the computer chips used to run AI, dropped 7 percent. Oracle fell 9 percent and Palantir dropped 11 percent. Even companies doing well overall, like Meta and Microsoft, went down about 4 percent after they told investors they would keep spending enormous amounts of money on AI.
Why Did Stocks Fall?
Experts say there are a few reasons the market went down. First, people think that technology company stock prices are already too high compared to the actual money they are making right now. When you pay a huge price for something, even small bad news can make it drop fast. Second, many companies told investors they would spend hundreds of billions of dollars on AI, but they haven't proven that this spending will actually make them more profitable. One stock market expert said the situation like this: costs are as big as the universe while profits are ant-sized.
AI Agents Get Big Money
While big tech stocks were falling, the world of AI agents — smart computer programs that can work by themselves — was booming with new funding. LangChain, a company that helps computer programmers build AI agents, raised $125 million dollars at a value of $1.25 billion. This company is important because programmers use LangChain's tools to create agents that can make decisions without a human telling them every single step.
Other AI agent companies also got money this week. Hyro makes AI agents that help doctors and hospitals work faster, and raised $45 million. Phaidra creates AI agents that help manage big computer data centers that run artificial intelligence, and raised $50 million. General Intuition makes AI reasoning models for autonomous agents and raised $35 million. Seraphina Systems builds AI agents that help scientists discover new medicines and raised $25 million in seed funding. Defakto creates security tools to protect AI agents from attacks and raised $30.75 million.
What This Means
This weekly update shows two completely different stories happening at the same time. The big, famous tech companies are facing tough questions about whether their massive AI spending will actually make money for shareholders. Stock traders are getting nervous because they see huge costs but haven't seen huge profits yet. However, smaller companies that are building specific AI tools, especially AI agents that can work independently, are still raising lots of money from investors. This suggests that even though some investors worry about the biggest tech companies, they still strongly believe that artificial intelligence and AI agents will be very important in the future. The market is basically saying: we're not sure if the giants got this right, but we definitely believe in the smaller companies building the next generation of AI technology.
