Marvell gives Google option to buy $12.2 billion stake in custom chip deal

Aug 19 (Reuters) – Marvell Technology will help develop Google’s in-demand custom chips and has given the tech giant the option to become one of its biggest ​investors through a stake purchase of as much as $12.2 ‌billion, in its latest move to tap the AI boom.

Shares of the chipmaker jumped more than 11% in premarket trading, while larger rival Broadcom — which has been Alphabet-owned Google’s main custom chip partner — fell over ‌2%.

Demand ​for in-house chips such as Google’s ⁠tensor processing units (TPUs) has ⁠surged as companies seek cheaper alternatives to Nvidia’s graphics processors and technologies better suited for inference, the process of running trained AI models.

The new tie-up covers a broad range ​of chips and related technologies designed to work with Google’s TPU ecosystem, which underpins much of the company’s AI ⁠infrastructure.

Under the deal, Google received ⁠a warrant to buy up to 58.97 million ​Marvell shares at $206.58 apiece.

If fully exercised, the warrant would be worth ​about $12.18 billion, according to Reuters calculations. A stake ‌of that size will make Google Marvell’s fifth-largest investor, according to data from LSEG.

Most of the warrant will become available only if Google meets agreed purchasing targets through fiscal 2033, linking ⁠the size of its potential Marvell stake to how much it buys from the chipmaker over time.

The agreement comes weeks after ⁠Big Tech companies ‌reinforced expectations that they would spend more than $700 ⁠billion on AI infrastructure this year, an ​unprecedented ‌sum that marks a big step up from ​last year’s $400 ⁠billion outlay.

Marvell faces stiff competition from Broadcom, which signed a long-term agreement with Google to develop and supply future generations of custom AI chips and other components for the company’s next-generation AI racks through 2031.
