Google Just Gave Marvell a $12.2 Billion Vote of Confidence — And Broadcom Lost 5% the Same Day

When Marvell Technology disclosed a new custom chip partnership with Google on August 19, its stock jumped more than 11%. Broadcom’s fell more than 5%. That divergence tells you almost everything about what the deal actually means.

What Was Announced

Marvell filed a regulatory disclosure revealing it has issued Alphabet’s Google a warrant to purchase up to 58,970,907 shares of its common stock at $206.58 per share — worth approximately $12.18 billion if fully exercised. The underlying commercial agreement was signed on July 29, and it covers a broad range of custom silicon attached to Google’s tensor processing unit ecosystem, including AI inference accelerators, storage controllers, network interface controllers, memory interface controllers, and near-memory computing technology. If fully exercised, the stake would make Google Marvell’s fifth-largest investor. The warrant is exercisable until August 18, 2033.

The shares don’t vest all at once. Only about 1.4 million vest automatically in the first year. The remaining 57.6 million are tied directly to how much Google spends with Marvell — approximately 240,000 shares vest for every $500 million in qualifying chip purchases. To earn the full $12.18 billion in equity, Google would need to send roughly $120 billion in chip revenue Marvell’s way through fiscal 2033. That $120 billion is a vesting threshold, not a spending commitment, but it signals the potential scale of the relationship if Google follows through.

Why Broadcom Sold Off

Broadcom has been Google’s primary custom chip partner, holding a deal that runs through 2031 and covers future generations of Google’s most advanced silicon. The Marvell announcement doesn’t replace that — Broadcom remains engaged — but it signals that Google is deliberately building a second, parallel custom chip relationship rather than deepening its dependence on a single supplier. For investors, that diversification reads as a relative vote of no-confidence in Broadcom’s exclusive positioning, even if the absolute relationship is unchanged. Marvell and Broadcom don’t compete on identical products; Morningstar analyst William Kerwin called the Marvell deal “a big win” while noting it likely reflects a “growing pie at Google for new sources, rather than” a direct transfer of business away from Broadcom.

Part of a Pattern Across Big Tech

The deal fits a template becoming standard among the largest AI infrastructure spenders: take a meaningful equity position in a key chip supplier in exchange for committing significant procurement volume, structuring the stake to scale automatically with spending. In October 2025, AMD struck an analogous deal with OpenAI — chips worth tens of billions in potential annual revenue, with OpenAI holding an option to buy up to roughly 10% of AMD. The structure aligns incentives both ways: the chip company gets a large committed customer; the customer gets equity upside on its own spend and a deeper engineering partnership with a supplier that has strong financial reasons to prioritize their roadmap.

The Broader Race to Build Custom Silicon

Demand for custom, task-specific chips has surged as AI companies discover that general-purpose Nvidia GPUs — however powerful — aren’t optimally efficient for inference, the process of running trained models at scale rather than training them in the first place. Google’s TPUs are the most mature example of this category, and the Marvell deal specifically targets the hardware that surrounds and enables TPUs rather than the TPUs themselves — the storage, networking, and memory controller chips that determine how efficiently a TPU cluster can actually be used in production. This connects directly to the same chip demand story driving TSMC’s blowout quarter and Samsung’s price hikes; see our coverage of Samsung’s foundry price increases for how AI demand is squeezing every layer of the hardware supply chain.

What to Watch Next

Marvell reports earnings August 27, and analysts are watching for detail on the revenue ramp tied to the Google deal. Prediction market data puts Google at just 7% odds to hold the best AI model by end of 2026, compared to 66% for Anthropic and 14.5% for xAI — a sobering context for a deal that’s ultimately a bet on winning the AI infrastructure race if not the model race outright.
