Google Takes a $12 Billion Option on Marvell's Chips

Google has secured the right to buy up to $12.2 billion of stock in Marvell Technology, part of a deepening deal for the custom silicon Google needs to keep its AI systems fed. Marvell issued the warrant on August 18, letting Google purchase nearly 59 million shares at $206.58 each, according to Quartz.

Marvell's stock rose more than 11 percent on the news. Broadcom, Marvell's larger rival in custom chip design and until now a key Google partner, fell.

An option, not a purchase

The structure matters. Google has not spent $12.2 billion. It holds a warrant, a standing option to buy the shares later at a fixed price. Most of that option vests only as Google actually buys custom chips from Marvell, one tranche for roughly every $500 million in orders, with the schedule running through 2033. Fully exercised, it would make Google the fifth-largest holder of Marvell and points to as much as $120 billion in future chip business, Reuters reported.

In other words, this is a commitment device. Marvell gets a marquee customer tied in with equity upside. Google gets priority and better pricing on the parts it plans to order anyway.

Why Google is doing this

Google already designs its own AI accelerators, the TPUs that run much of its training and inference, and Marvell helps turn those designs into working silicon alongside the networking and storage controllers that surround them. Locking in that supply reduces Google's dependence on Nvidia, whose chips remain the default for most of the industry and command prices to match.

The move rhymes with a run of deals in which the largest AI buyers are reaching further down the supply chain to guarantee capacity. Anthropic has backed a chip startup of its own, memory makers like SK Hynix are flush with AI cash, and Nvidia keeps fending off challengers at the high end. Google's answer is to put money on the table for a second source, and to make sure that source has every reason to prioritise it.

What to watch

Broadcom's slide is the tell. For years it was the go-to partner for Google's custom chips, and the market read the Marvell warrant as a shift in that relationship. The deal does not end it, but it signals that Google wants competition among its suppliers and is willing to pay to keep two of them hungry.
