Marvell Fires Warning Shot at Broadcom and Nvidia With Big AI Chip Bet[Stocks](https://moneymorning.com/category/article/stocks/) # Marvell Fires Warning Shot at Broadcom and Nvidia With Big AI Chip Bet  by Rich Duprey  December 3, 2025  Share it: **Marvell Technology** ( [MRVL](https://moneymorning.com/stocks/mrvl/)), long seen as a solid but under-the-radar player in the AI chip race, just made its boldest move yet. Yesterday, the company announced it is buying **Celestial AI**, a fast-rising startup that uses light instead of electricity to move data inside massive AI data centers, for $3.25 billion in cash and stock. The deal is pushing Marvell’s shares up more than 10% in pre-market trading today and putting the entire semiconductor world on notice: the era of optical connections in AI is closer than most investors thought, and Marvell intends to be at the front of the pack. ## Marvell's Data Center Land Grab Celestial AI’s big idea is simple but powerful: instead of sending data through copper wires that waste power and create heat, it uses tiny lasers and glass-like pathways to shuttle information with light. The result is faster communication between chips, much lower electricity bills, and the ability to connect thousands of AI processors across an entire warehouse without slowing down. Marvell already builds many of the custom chips and networking gear that power **Amazon** ( [AMZN](https://moneymorning.com/stocks/amzn/)), Google, and **Microsoft** ( [MSFT](https://moneymorning.com/stocks/msft/)) data centers. By swallowing Celestial, Marvell can now offer a complete “light-based” plumbing system that plugs straight into its existing products. Think of it as upgrading from garden hoses to fiber-optic cables inside the world’s biggest AI supercomputers. Management laid out an aggressive roadmap on the conference call. They expect Celestial’s technology to start adding real money in late 2027, hitting a $1 billion annual run rate by the end of calendar 2029. That’s on top of the roughly $10 billion in total revenue Marvell already expects for its fiscal 2027. In short, the company believes optical connections will become a multibillion-dollar business for them within four years.  ## Taking the Fight to Broadcom and Nvidia Broadcom dominates the market for high-speed switches and custom Google AI chips, while Nvidia still owns the GPU throne and sells its own ultra-fast (but electricity-hungry) networking gear. Both rely mostly on traditional electrical connections today. Marvell’s bet is that light-based links will become the cheaper, cooler, and more scalable choice as data centers grow to millions of chips. If hyperscalers like Amazon (which just signed a big optics warrant with Marvell) and others agree, a meaningful slice of the tens of billions spent on networking could shift away from Broadcom and Nvidia toward Marvell’s integrated optical solutions. ## Bottom Line If photonics delivers even half of what Marvell and its customers expect, this acquisition could catapult the company from a strong No. 3 or No. 4 player into a true peer of Broadcom and Nvidia in the data center food chain. For investors, that’s the exciting part: Marvell trades at a cheaper valuation than both rivals, yet could grow faster if light really does beat electricity at scale. The big “if,” of course, is adoption speed. Photonics has been the next big thing for years, but costs are finally dropping and power bills are exploding. History says the technology that solves the hottest pain point usually wins. Right now, that pain point is power-hungry copper cables inside trillion-dollar AI factories. Marvell just placed the biggest public bet that light is about to take over. **Beat the market, without relying on brokers or biased institutions.** Email(Required) Company This field is for validation purposes and should be left unchanged.
