    Is Cadence (CDNS) Using Lightmatter’s Photonics Tie-Up to Redefine Its Custom AI Chip Role?

    Simply Wall St·02/05/2026 13:34:50
    Listen to the news
    • In January 2026, Lightmatter announced a technical collaboration with Cadence Design Systems to combine Cadence’s silicon-proven high-speed SerDes and UCIe IP with Lightmatter’s Passage optical engine for co-packaged optics in advanced AI and high-performance computing systems.
    • This partnership highlights how Cadence’s chip-design and packaging expertise is being woven into next-generation photonic interconnects, positioning its technology at the center of emerging custom AI infrastructure chips for hyperscalers.
    • Against this backdrop, we’ll examine how Cadence’s push into co-packaged optics with Lightmatter could reshape its broader investment narrative.

    What Is Cadence Design Systems' Investment Narrative?

    To own Cadence, you really need to believe that its EDA tools and chip IP will remain essential to how advanced AI and high‑performance chips get designed, verified, and packaged. The recent pullback in the share price, despite upgraded 2025 guidance and consistent buybacks, underlines how sensitive a high multiple stock can be when sentiment swings against software, even when earnings and revenue are still expected to grow. The new Lightmatter collaboration fits squarely into the near term catalysts: it extends Cadence’s reach into co‑packaged optics and photonic interconnects for hyperscalers, reinforcing its role in emerging custom AI infrastructure rather than traditional SaaS. That said, the partnership is early and unlikely to move the financial needle immediately, while valuation, slower recent profit growth, and a premium P/E remain key risks.

    However, investors should also weigh how Cadence’s premium valuation could magnify any disappointment. Cadence Design Systems' share price has been on the slide but might be up to 10% below fair value. Find out if it's a bargain.
