SES AI shares fell 6.28% amid AI sector valuation concerns and macroeconomic uncertainty

Shares of SES AI fell 6.28% in pre-market trading on December 31, 2025, signaling a sharp decline ahead of the new year. The drop came amid broader market concerns over AI sector valuations and macroeconomic uncertainty.

Analysts noted that the sell-off reflected investor caution following mixed earnings guidance from key AI infrastructure providers. Recent regulatory scrutiny of AI algorithms and data privacy practices also weighed on sentiment. Despite a surge in generative AI adoption, market participants remain wary of near-term profit sustainability in the sector.

Technical indicators show the stock has broken below critical support levels, raising questions about short-term momentum. However, long-term bullish fundamentals—including growing enterprise demand for AI solutions—remain intact. Investors are advised to monitor upcoming quarterly reports for clarity on revenue trends and R&D progress.

The decline underscores the sector's volatility as investors balance optimism about AI's transformative potential with skepticism over execution risks. Positioning appears to be shifting toward a "wait-and-see" approach ahead of potential policy updates in early 2026.
