Google Locks In a $12.2B Marvell Stake as Its TPU Chip Alliance Deepens

This time, Google didn’t just pay cash for chips — it walked away with a $12.2 billion stock option. On August 19, chipmaker Marvell announced it had granted Google a warrant to buy up to 58.97 million Marvell shares at $206.58 apiece, worth roughly $12.18 billion if fully exercised, instantly making Google Marvell’s fifth-largest shareholder. Marvell’s stock jumped nearly 8% on the news, while Broadcom — Google’s longtime primary custom-chip partner — fell more than 5%.

The Option Isn’t Free — It’s Tied to Purchase Targets

This warrant isn’t an unconditional gift. Under the agreement, the bulk of the share option only unlocks as Google hits mutually agreed purchasing targets, on a timeline stretching out through fiscal 2033. In other words, Marvell has tied its own potential future stock upside directly to how much — and whether — Google actually buys from it: the more Google purchases, the more shares it can claim. Trading equity for a long-term purchase commitment isn’t a new pattern in the AI supply chain, but a deal of this size, at $12.2 billion, is still unusual.

The Deal Covers More Than Just Chips

The scope of the agreement is broad — it’s not limited to the processors that run AI models, but also extends to technology for managing data storage and moving information across networks. In short, it’s the entire ecosystem of supporting technology around Google’s in-house Tensor Processing Units (TPUs), not just chip fabrication for a single component. If Google hits its purchasing targets, the deal is projected to bring Marvell roughly $120 billion in revenue through fiscal 2033 — a scale big enough to reshape Marvell’s revenue structure for the next decade.

Is Broadcom Being Replaced?

The most closely watched part of this deal may not be how much money Marvell stands to make, but what it means for Broadcom. For years, Broadcom has been Google’s primary partner for custom AI chips; now Google has visibly pulled Marvell up to the same table, and the market reacted immediately — Broadcom’s shares dropped more than 5%. Morningstar analyst William Kerwin offered a different read, though, calling the deal “a big win for Marvell” while framing it for Google as adding a new supply line and expanding its own negotiating leverage, rather than necessarily displacing Broadcom’s position in Google’s custom-chip roadmap.

Why Google Builds Its Own TPUs

Google has spent recent years steadily doubling down on its own Tensor Processing Units, largely because it doesn’t want the lifeline of its AI computing to depend entirely on Nvidia’s GPU supply — Nvidia chips are in tight supply and expensive, and TPUs let Google build hardware customized to its own models’ computational characteristics, lowering training and inference costs over the long run. But building its own chips still requires outside fabrication and supporting-technology partners; that role has mostly belonged to Broadcom until now. Marvell’s formal entry into the mix gives Google another card to play in its chip supply chain, and a bit more leverage in negotiations with either partner.

Why Big Tech Is Locking In Suppliers With Equity

Google isn’t the only tech giant tying itself to chip suppliers through equity or long-term commitments — the sheer scale of capital spending on AI infrastructure has grown large enough that cloud giants are choosing to take direct stakes in key suppliers to secure capacity and priority access, rather than simply signing a purchase contract. For Marvell, landing Google as a partner secures a firmer foothold in an AI chip market still dominated by Nvidia and Broadcom. For Google, it’s extra insurance for its TPU roadmap, reducing over-reliance on any single supplier.

How the Market Is Reading This

Beyond Marvell’s surge and Broadcom’s slide, Alphabet’s own stock barely moved on the day — a sign the market is reading this deal as a reshuffling of the chip supply chain rather than a major shift in Google’s underlying business. It also echoes a broader pattern emerging in the AI industry: cloud providers, chip designers, and foundries are increasingly binding their financial fates together through cross-holdings, long-term purchase agreements, and option structures. That’s partly a byproduct of the AI infrastructure buildout, but it’s also fueling outside concern about whether the entire supply chain’s valuations now rest too heavily on a handful of mega-deals.
