Can Marvell’s Celestial AI deal make it a serious threat to NVIDIA in AI infrastructure?

Marvell Technology (NASDAQ: MRVL) is in advanced discussions to acquire Celestial AI in a cash-and-stock transaction that could exceed $5 billion in value, according to sources familiar with the matter. The potential deal would mark one of the largest acquisitions in the emerging AI hardware segment and could be publicly announced as early as this week. The development signals Marvell’s strategic push to establish a foothold in photonic interconnect technology, positioning the chipmaker to capitalize on growing demand for scalable AI data center architectures.

Celestial AI is a Santa Clara–based startup known for its proprietary “Photonic Fabric” platform, which leverages optical data transfer to dramatically accelerate communication between memory and compute units in AI systems. Despite being pre-revenue, Celestial AI has drawn widespread interest due to its potential to resolve a longstanding bottleneck in AI infrastructure: the memory bandwidth constraint that limits data movement in large-scale model training and inference.

By moving forward with this acquisition, Marvell appears intent on embedding optical interconnects directly into its AI and data center chip portfolio, a move that could challenge both custom ASIC suppliers and hyperscaler-aligned silicon vendors.

Why is Marvell pursuing a high-risk acquisition of a pre-revenue optical interconnect startup?

The strategic rationale centers on memory disaggregation and AI compute scalability. As AI models grow more complex, the demand for high-bandwidth, low-latency connections between processors and memory modules is rapidly outpacing the capabilities of traditional copper-based interconnects. Celestial AI’s solution addresses this by using light instead of electricity to transfer data between chips. This photonic interconnect model enables higher throughput, lower power consumption, and more modular system architectures, particularly for cloud-scale workloads.

Marvell, already active in high-speed networking and optical DSPs, sees the acquisition as a way to control more of the value chain. The integration of Celestial AI’s technology could enhance Marvell’s existing AI accelerators, memory controllers, and custom silicon offerings. In effect, the acquisition would give Marvell a differentiated platform-level play in future AI clusters that rely on memory pooling and data movement fabrics.

Industry analysts tracking the semiconductor sector believe that photonic interconnects may become a defining characteristic of next-generation AI infrastructure, especially as cloud providers seek to minimize latency and energy overhead in distributed compute environments.

What technology advantages does Celestial AI offer Marvell’s AI data center ambitions?

Celestial AI’s core product, the Photonic Fabric, is designed to replace conventional electrical pathways with optical links between compute and memory components. This approach directly targets the so-called “memory wall,” a term used to describe the growing disparity between processor speed and memory access bandwidth. In traditional systems, this bottleneck slows down large-scale inference and model training, consuming more power and space.

The startup’s architecture supports disaggregated memory and multi-node connectivity, allowing AI workloads to tap into larger pools of shared memory without sacrificing speed. For hyperscalers running billion-parameter models across distributed clusters, this capability can translate into performance gains and operational cost savings.

Celestial AI has raised over $500 million to date, including a $175 million Series C round in March 2025 led by Koch Disruptive Technologies and Advanced Micro Devices. The company further expanded its IP base by acquiring over 90 patents in silicon photonics from Rockley Photonics earlier this year, bolstering its ability to commercialize and defend its innovations.

Despite the technical promise, Celestial AI has yet to generate revenue from commercial deployments. Its photonic interconnects are still in the early stages of evaluation by data center customers and remain unproven at production scale.

How does this deal fit into broader semiconductor industry consolidation around AI infrastructure?

The potential acquisition reflects a broader industry trend where semiconductor companies are moving to vertically integrate critical AI infrastructure layers. NVIDIA has already expanded into interconnects and networking through its acquisitions of Mellanox and Cumulus. Advanced Micro Devices has deepened its AI strategy via M&A, including its acquisition of Nod.ai and Pensando.

Marvell’s own acquisition history includes the 2023 purchase of Tanzanite Silicon Solutions, a move that brought memory pooling expertise into its portfolio. Buying Celestial AI would extend that logic into the physical layer by enabling faster, more efficient chip-to-chip communication.

Analysts believe the deal underscores how vendors are no longer focused solely on compute performance but are racing to solve system-level bottlenecks. Photonics, particularly for AI workloads, is increasingly viewed as a transformative enabler—not just a supporting component.

If successful, this deal could make Marvell a central player in supplying the photonic infrastructure needed by hyperscalers, national labs, and enterprise AI systems. It also reflects mounting pressure on semiconductor companies to differentiate their offerings in a market saturated with generic accelerators.

What are the challenges and risks in integrating a photonics startup into Marvell’s roadmap?

There are several execution risks that investors and technology observers will be monitoring closely. First, photonic interconnects remain a complex and manufacturing-intensive technology. Scaling production to meet hyperscaler demand will require robust packaging, thermal, and reliability engineering capabilities.

Second, Celestial AI’s products have not yet achieved wide-scale customer validation. Although the company has shown promising benchmarks, it still needs to prove real-world performance across diverse AI workloads in cloud environments. Any integration into Marvell’s product lines would require extensive qualification, especially in mission-critical data center applications.

Third, the economics of the deal will come under scrutiny. Because the transaction is expected to be a mix of cash and stock, with milestone-based earnouts, much of the total value will depend on Celestial AI’s future delivery of commercial results. This structure introduces significant conditionality, and the dilution or return profile for Marvell shareholders may vary depending on how those milestones play out.

Historical examples like Intel’s venture into silicon photonics suggest that commercializing optical interconnects can take far longer than anticipated, especially when legacy electrical infrastructure dominates current data center designs.

How are markets and institutional investors reacting to the news?

Marvell Technology’s share price closed flat at $64.72 on Monday following the news, with little immediate impact. The stock has declined roughly 1.8 percent over the past five trading days. Broader market conditions for semiconductors were also soft during the period, making it difficult to isolate the reaction to this specific report.

Sell-side analysts maintained a mixed but slightly positive stance on Marvell, viewing the potential acquisition as strategically sound but operationally complex. Some investment research notes cited the importance of execution, warning that integrating photonics technology into Marvell’s silicon ecosystem would require a multi-year effort.

From an institutional perspective, fund flows into Marvell have been steady in recent quarters, driven by optimism around its AI and cloud data center exposure. However, short-term sentiment could be tempered by concerns about capital deployment and dilution, especially if the deal is finalized with a premium valuation.

While the acquisition could enhance Marvell’s long-term competitive position, the near-term reaction appears to be one of cautious optimism rather than outright enthusiasm.

What will analysts and investors watch for in the weeks ahead?

If the transaction is finalized, key focus areas will include milestone definitions, customer adoption timelines, and deployment partnerships. Investors will want visibility into whether hyperscaler clients are actively testing Celestial AI’s Photonic Fabric platform and whether there are reference designs tied to Marvell’s silicon.

Analysts will also be watching for updates during Marvell’s next earnings call, particularly around capital expenditure expectations, potential revenue contribution timelines, and integration strategy. Regulatory hurdles are expected to be minimal, given the pre-revenue nature of the startup and the deal’s non-horizontal structure.

Ultimately, the market will judge the success of the transaction based on Marvell’s ability to bring Celestial AI’s technology to scale and deliver meaningful performance or cost advantages in commercial AI systems.

If those milestones are met, this acquisition could become a defining moment in Marvell’s evolution from a specialty networking chipmaker into a full-stack AI infrastructure provider.
