AI debt fears send investors running to US bonds

Investors rushed into U.S. government bonds this week, pushing yields lower, as worries about rising debt tied to artificial intelligence (AI) sent them searching for safer places to put their money. Yields fall when bond prices rise. The move shows how nervous traders have become about the borrowing boom behind the AI industry. AI companies are spending heavily on data centers and computing power, much of it funded by debt. Investors fear that if the spending slows or the debt becomes too large to manage, the fallout could spread through markets. When markets get shaky, traders often move money into U.S. Treasuries, long seen as one of the safest investments in the world. This week, that is exactly what happened. The shift lowered yields for the week, a sign that demand for safe-haven bonds stayed strong even as concerns about AI-related borrowing grew.
