Every $500M Google Spends at Marvell Earns It a Piece of Marvell

TL;DR

On August 19, Marvell disclosed in an SEC 8-K that it signed a sweeping custom-silicon agreement with Google back on July 29, and sealed it on August 18 by issuing Google a warrant to buy up to 58,970,907 Marvell shares at $206.58 apiece, roughly $12.2 billion of stock at full exercise. Almost none of it vests for showing up: the warrant unlocks in 240 equal tranches, one for every $500 million Google spends on Marvell custom chips through fiscal 2033. Run the ladder to the top and it implies up to $120 billion in orders. Marvell jumped nearly 8% on the news, Broadcom fell more than 5%, and the equity-for-orders deal structure that AMD ran on OpenAI last October is now officially a genre.

A three-week-old deal, disclosed by securities law

There was no keynote and no joint press release. The commercial agreement was signed July 29, the warrant was executed August 18, and the world found out August 19 from a Form 8-K, the corporate equivalent of learning about a wedding from the county clerk.

The filing is short but dense. Marvell will develop what the document calls Custom Products for Google, spanning "a comprehensive range of custom silicon programs that attach to the TPU ecosystem, including AI inference accelerators, storage controllers, network interface controllers, memory interface controllers, and near-memory compute." In exchange for the business, Google gets the warrant: 58,970,907 shares at a $206.58 strike, exercisable any time until August 18, 2033, non-transferable except to Google's own affiliates.

The vesting machine

Here is the part worth actually reading. Only 1,360,867 of those shares are time-based, vesting quarterly across the first year just for signing. The other 57,610,040 shares, 97.7% of the warrant, vest exclusively as Google buys chips: one tranche of roughly 240,000 shares for every $500 million in Custom Products revenue Marvell books, counted from Marvell's third quarter of fiscal 2027 through the end of its fiscal 2033.

Think of it as a loyalty punch card, except every punch is $500 million and the fully stamped card is worth a top-five shareholder position in the coffee shop. Coverage of the deal notes that full exercise would make Google Marvell's fifth-largest investor.

Note what the $12.2 billion actually is: the price Google would pay to exercise everything, not a gift. The strike was set near where Marvell traded, so the warrant is worth real money only if Marvell's stock rises, and the single biggest thing that would make Marvell's stock rise is Google buying chips at nine-figure-per-tranche scale. The incentive design is airtight enough to be a little funny: Google, a company not historically in need of encouragement to spend money, now gets paid to shop.

What Google is actually buying, and why Broadcom flinched

Google's TPUs have long been co-designed with Broadcom, and the market read this filing as Marvell getting a foot inside that door: Broadcom dropped more than 5% on the day while Marvell rose nearly 8% and Alphabet barely moved.

The calmer read is that nothing in the 8-K says Marvell is taking over the TPU itself. The listed programs are the silicon around the TPU: inference accelerators, storage, networking, memory interfaces, near-memory compute. Morningstar analyst William Kerwin called the deal "a big win for Marvell" while framing it as "a growing pie at Google for new sources, rather than a competitive displacement of Broadcom." Still, "AI inference accelerators" is the first item on the list, and an inference accelerator attached to the TPU ecosystem that Broadcom does not build is precisely the kind of second source hyperscalers spend years engineering into existence. Marvell already does custom-silicon work for other hyperscalers, including a multi-generational agreement with AWS announced at the end of 2024, so Google was the conspicuous gap in the roster.

Equity-for-orders is now a standard contract shape

If the structure feels familiar, it should. In October 2025, AMD issued OpenAI a warrant for up to 160 million shares tied to deploying up to 6 gigawatts of Instinct GPUs. The differences are instructive. AMD struck its warrant at one cent per share, essentially free equity gated behind delivery milestones and aggressive stock-price targets. Marvell struck Google at market, so Google's payoff is pure upside participation rather than a handout.

Both deals invert the arrangement Nvidia made famous, where the chip supplier invests in its own customers to prime demand. Here the money flows the other way: suppliers hand equity exposure to their biggest buyers to lock in multi-year order books. When the scarce resource was chips, customers paid for priority. Now that every hyperscaler is designing custom silicon and shopping the build-out, the scarce resource is a committed anchor tenant, and suppliers are paying for that.

Why builders should care

You will never buy one of these chips, but you will rent the consequences. A vesting ladder that tops out at $120 billion through fiscal 2033 is Google signaling that the TPU ecosystem build-out has years of aggressive expansion left, with a second custom-silicon supplier feeding it. More TPU-attached capacity is what determines Gemini serving costs, Google Cloud TPU availability, and inference pricing across everyone who runs on that hardware, Anthropic included, since Claude serves substantial traffic from TPUs. It is also one more datapoint that the biggest AI buyers are methodically building lives that do not revolve around Nvidia's allocation schedule.

Caveats, straight-faced

• The purchases are explicitly discretionary. The 8-K commits Google to nothing; the $120 billion is a ceiling implied by the tranche math, not a forecast, and not guidance from either company.
• Purchase-vested tranches only start counting from Marvell's fiscal Q3 2027, so the revenue shows up gradually, not this quarter.
• The warrant's exercise price and share count carry customary adjustment clauses, so the exact figures can shift with corporate actions.
• Neither company has said which products ship first or when. The stock moves reflect expectations, not silicon.

Key Takeaways

• Marvell granted Google a warrant on 58,970,907 shares at $206.58, disclosed August 19 in an SEC 8-K covering a commercial agreement signed July 29.
• 97.7% of the warrant vests only as Google buys: 240 tranches, one per $500 million in custom-chip revenue, implying up to $120 billion in orders through fiscal 2033.
• The deal covers TPU-ecosystem silicon including AI inference accelerators, networking, storage, and near-memory compute, territory adjacent to Broadcom's TPU franchise.
• Markets reacted accordingly: Marvell up nearly 8%, Broadcom down more than 5%, Alphabet flat.
• Supplier-grants-customer-equity is now a repeating pattern after AMD's penny-strike warrant to OpenAI, but Marvell's market-price strike makes Google's payoff upside-only.
• For builders, this is a multi-year capacity signal for the TPU ecosystem, the main non-Nvidia serving platform for frontier models.
