Marvell has acquired Celestial AI for an undisclosed amount. Celestial AI specializes in developing Photonic Fabric technology, a revolutionary optical interconnect solution designed to scale artificial intelligence compute power. This technology addresses the limitations of traditional electronic interconnects by enabling efficient data movement and high computational power within packages, package-to-package, and across multiple racks, forming the foundation for optical scale-up networks in AI infrastructure.
The acquisition is strategically aimed at accelerating the adoption of optical scale-up connectivity for next-generation AI and cloud data centers. Celestial AI's Photonic Fabric offers terabytes of low-latency bandwidth, in-network computing, and high-performance memory, which are critical for supporting the exponential growth of AI workloads. By switching to optical interconnects, the combined entity expects to facilitate larger multi-die packages and expanded scale-up domains, pushing capabilities into the next decade.
Expected synergies include the transformation of AI data centers, enabling the scaling of thousands of XPUs across racks to support larger models, improved reasoning, and more efficient inference. This integration is also anticipated to reduce the total cost of ownership for AI infrastructure, unlocking new use cases and more profitable GenAI business models. Celestial AI’s aggressive roadmap, robust ecosystem, and tier-one supply chain are expected to complement Marvell's capabilities in delivering advanced solutions for the AI market.
The combination of Marvell and Celestial AI is poised to deliver a new era of sustainable and scalable compute capacity. This strategic move aims to illuminate the future of AI by providing the necessary infrastructure to unlock creativity, solve complex challenges, and support continued innovation in artificial intelligence.
