Buy the dip in EDA stocks as Kimi K3 boosts agentic AI thesis: Mizuho

Investing.com -- Mizuho said the release of Moonshot's Kimi K3 model reinforces its agentic AI thesis for electronic design automation software rather than threatening it, recommending investors buy the dip in Synopsys and Cadence Design Systems following last week's selloff.

Mizuho’s TMT Sector Specialist Jordan Klein noted that both SNPS and CDNS sold off 8-10% last Friday on fears of open-source AI model chip design competition out of China.

Mizuho "believe[s] this risk is way overblown" and reiterated its bullish stance on both stocks.

The firm said K3 "operated as a general-purpose agent using existing open source EDA tools (such as OpenRoad) orchestrating the EDA flow, rather than replacing the underlying EDA tools/software."

Klein said this aligns with its view that foundation models "cannot substitute for deterministic, physically accurate solvers," and that autonomous agents drive incremental usage of EDA tools rather than displacing them.

This development is said to reinforce Mizuho’s "agentic AI engineer thesis," where agentic AI for design addresses a structural talent gap across the semiconductor design industry, expanding EDA monetization from tools to engineering labor value, and potentially tripling the core EDA total addressable market.

On broader capex implications, Mizuho stated falling model prices don't necessarily threaten infrastructure spending, noting "the infrastructure required to build and run frontier AI remains enormously expensive."

The firm added that lower-cost open-source models could actually accelerate rather than slow capex from frontier model builders seeking to maintain their competitive edge.
