On September 15, Synopsys fell 3.08% in regular trading, trading at 369.87 USD/share, with turnover of approximately $170 million. Market concerns over AI large language models disrupting the traditional EDA industry continued to ferment, pressuring the stock.

The overhang traces back to when Moonshot AI released Kimi K3, whose autonomous agent completed the design, optimization, and verification of an inference chip prototype within just 48 hours without any human intervention, using only open-source EDA tools. That event previously triggered an intraday plunge exceeding 12% for Synopsys. Despite multiple analyst upgrades in recent weeks — Morgan Stanley upgrading to Overweight with a $500 target, Wells Fargo raising its target to $475, and Baird setting a $560 target — the structural concern that AI-native agents could bypass traditional EDA tools continues to weigh on sentiment.

Notably, Synopsys reported a strong fiscal Q3, with adjusted EPS of $3.91 beating estimates by 6.5%, and raised full-year revenue guidance to $9.69–9.74 billion. The company has also launched its own autonomous AI engineering workflows in partnership with NVIDIA and AMD.
