Marvell Expands AI Data Center Reach with Celestial AI and PCIe 8.0

• Marvell Technology (NasdaqGS:MRVL) has completed its acquisition of Celestial AI, expanding its high-bandwidth, low-latency connectivity capabilities for AI and cloud data centers.
• The company will also showcase its early PCIe 8.0 SerDes technology at DesignCon 2026, with the goal of doubling future bandwidth for next-generation infrastructure.

Marvell, best known for its data infrastructure semiconductors, is increasingly focused on building AI and cloud data centers. With the addition of Celestial AI’s optical interconnect technology, the company aims to address the growing demand for faster movement of data within and between servers as model sizes and workloads increase.

The PCIe 8.0 SerDes preview gives hyperscalers and data center operators an early look at the connectivity expected to support higher bandwidth systems. For investors, these developments signal that NasdaqGS:MRVL is a company that is aligning its product roadmap more closely with AI infrastructure, a theme that many large chip and cloud companies are prioritizing.

📰 Beyond the headlines: 1 risk and 5 things that are going well for Marvell Technologies that every investor should pay attention to.

For you as an investor, this news ties together two key elements of Marvell’s story: owning more AI data flows within your data center and sustaining next-generation standards early. Celestial AI provides photonic fabrics and optical interconnects designed to move data between chips and servers at extremely high speeds with low latency. This fits directly into Marvell’s focus on AI and cloud customers. At the same time, showing off the 256 GT/s PCIe 8.0 SerDes at DesignCon 2026 signals to hyperscalers that Marvell wants a seat at the table when planning their infrastructure through the next PCIe cycle.

How does this fit into Marvel’s technology story?

• The acquisition of Celestial AI aligns with the narrative around AI optics and custom silicon as drivers of future data center growth and strengthens Marvell’s commitment to high-bandwidth connectivity for large-scale cloud customers.
• Increasing reliance on advanced AI data center projects increases exposure to revenue concentration and project-specific risks already highlighted in the narrative, especially if hyperscalers adjust their capital expenditures or pursue additional proprietary silicon.
• The early PCIe 8.0 capabilities and tight integration of optical fabrics may not yet fully translate into existing expectations, especially regarding how Marvell will compete with companies like Broadcom, Nvidia, and AMD in next-generation interconnects.

Risks and rewards investors should consider

• ⚠️ The acquisition adds integration and execution risks on top of already high R&D costs, and analysts note at least one risk to earnings quality, including the impact of one-time items on reported results.
• ⚠️ Increased focus on AI data center customers, including major hyperscalers, could put Marvell at further risk if sentiment toward AI infrastructure weakens or if competitors such as Broadcom or Nvidia acquire major optical silicon and custom silicon programs.
• 🎁 Marvell has recently been confirmed to fit an “affordable growth” profile and to be profitable, with revenue and earnings expected to increase, which some investors may see as support for the long-term AI and cloud thesis.
• The Celestial AI deal and PCIe 8.0 SerDes efforts align Marvell with competitors like AMD and Nvidia on the subject of optical interconnects and high-speed connectivity that many see as central to large-scale AI training and inference.

Future points of interest

From now on, it will be interesting to see how quickly Marvell turns its Celestial AI technology into a design win and measurable revenue growth, especially with Amazon listed as an early customer and expected revenue contribution starting in the second half of fiscal 2028. Progress on PCIe 7.0 and 8.0, including customer trials and ecosystem support with partners such as TE Connectivity, is also important to Marvell’s position in high-bandwidth links within and between racks. Finally, we will monitor how analyst expectations for AI-related data center revenue and margins adjust as the company integrates Celestial AI and continues to invest in custom silicon and optics alongside competitors such as Broadcom, AMD, and Nvidia.
