Analysis:AI debt faces pressure as Democrats prepare to take over Congress

US bond investors are becoming more cautious about debt tied to the rapid growth of artificial intelligence (AI), due to potential Democratic-led efforts to regulate the technology. The spread between investment-grade and high-yield corporate credit in the US widened to 348 basis points last Thursday, the highest since May 2025.

However, it narrowed to 342 basis points on Friday. Analysts warn that the markets are anxious and could see continued volatility in high-yield and investment-grade debt as regulators consider stricter AI rules. Democrats plan to introduce new AI-related legislation when they take control of Congress in January, while Republicans have recently shown openness to AI safeguards following a mid-term loss.

High-yield credit spreads have narrowed as the market reassesses AI-related risks, but the potential impact of AI regulation on economic growth remains a concern for investors.
