Most chip suppliers spend years trying to win a single hyperscale customer.
Marvell Technology (MRVL) just deepened its ties with all three of the largest ones, and it did so by giving Google a reason to keep spending.
On August 19, 2026, Marvell disclosed an expanded custom chip agreement with Alphabet‘s (GOOGL) Google.
The company also handed Google a warrant, which is a contract that lets the holder buy stock later at a set price.
Marvell stock jumped, but the structure of the deal is what shareholders need to understand.
Google does not get a cheap stake for free. It has to earn most of it by buying billions of dollars in chips.
That single condition changes how investors should read this news, and it decides whether the deal rewards current stockholders or costs them.
How the Marvell and Google custom chip deal actually works
Marvell agreed to develop a range of custom semiconductors for Google’s AI systems.
It issued Google a warrant to buy up to 58.97 million Marvell shares at a fixed price of $206.58, Reuters reported.
At that price, the full position would be worth about $12.2 billion.

The warrant does not force Google to invest that money now. Only about 1.4 million shares become available to Google in the first year, according to Marvell’s SEC filing.
The rest is tied to spending.
One block of shares unlocks for every $500 million in custom chip revenue Marvell books from Google, running from the third quarter of fiscal 2027 through fiscal 2033.
To unlock the whole stake, Google would need to buy roughly $120 billion in Marvell products over that stretch, Reuters reported.
Google can exercise the warrant until August 18, 2033.
Why Marvell stock jumped on the Google agreement
Marvell shares rose sharply on the news of the deal, gaining roughly 10% on August 19 and closing near $234, CNBC reported.
Investors reacted to what the deal signals about Marvell’s position.
Google has relied mainly on Broadcom (AVGO) to co-design its Tensor Processing Units, the custom chips that run much of its AI work.
This agreement adds Marvell as a second major supplier inside that system.
Marvell already builds custom silicon for Amazon (AMZN) and Microsoft (MSFT), so the Google deal gives it a foothold with all three of the biggest US cloud providers.
Broadcom shares fell about 4% to 5% the same day as investors considered the new competition.
Broadcom still holds a long-term Google agreement running through 2031, so this is added competition rather than a replacement.
The bull case: locked-in demand and a bigger AI customer
The appeal for Marvell shareholders is the incentive built into the warrant.
Google only earns its discounted shares by spending money with Marvell. That ties one of the largest AI spenders in the world directly to Marvell’s revenue for years.
Big Tech firms are expected to spend more than $700 billion on AI infrastructure this year, Reuters reported.

Marvell now has a formal path to a larger share of Google’s portion of that budget.
The work also goes beyond one chip.
Marvell will develop AI inference accelerators, storage controllers, networking hardware, and memory technologies for Google, according to its SEC filing.
Inference is the stage where a trained AI model answers real user requests, and it is becoming a large and steady source of chip demand.
The risk investors cannot ignore: share dilution
The same warrant that rewards Marvell also carries a cost for existing owners.
If Google unlocks and exercises all 58.97 million shares, Marvell must issue new stock.
That would dilute current shareholders by about 6.3% to 6.7%, Yahoo Finance reported.
Dilution means each existing share represents a smaller slice of the company.
Here is the part that softens the concern. Full dilution only happens if Google hands Marvell roughly $120 billion in revenue first.
Many analysts view that as a productive trade. Marvell would give up a share of ownership only in exchange for years of guaranteed sales.
Google would become Marvell’s fifth-largest investor if it fully exercised the warrant.
What still has to happen before the deal pays off
The headline number is large, but it depends on actions that have not yet occurred.
For the full value to arrive, several things need to hold up:
- Google keeps buying Marvell chips at scale through fiscal 2033.
- Marvell delivers competitive custom silicon on schedule.
- AI infrastructure spending stays strong across the cloud industry.
- Google’s TPU roadmap continues to rely on outside suppliers.
Not all analysts read the deal as a blow to Broadcom.
Morningstar analyst William Kerwin called it a strong win for Marvell but described it as Google adding new suppliers rather than dropping Broadcom.
Marvell stock versus the broader chip trade in 2026
Marvell had a rough summer before this deal, and the stock fell sharply in the weeks leading up to the announcement.
The Google news reversed part of that decline in a single session.
Compared with peers, Marvell has lagged the biggest gainers.
AMD (AMD) has surged more than 120% in 2026, while Nvidia (NVDA) is up about 18%.
The Google agreement gives Marvell a specific catalyst that those comparisons did not price in before.
Investors will get another read soon.
Marvell reports quarterly results on August 27, and its management’s commentary on Google demand will matter more than the warrant headline.
What Marvell shareholders should watch next
This deal improves Marvell’s standing, but it is a multiyear setup rather than an immediate payout.
The practical takeaway is to track the spending, not the $12.2 billion figure.

Each $500 million Google spends unlocks another block of shares, so revenue updates are the clearest sign the deal is working.
Watch three things in the coming quarters:
- Marvell’s custom chip revenue from Google, reported over time.
- Data center capital spending at Google and Amazon.
- Any change in how quickly the warrant tranches vest.
If Marvell can convert this agreement into steady, growing orders, the dilution becomes a fair price for durable revenue.
If Google’s spending comes in slower than expected, the stake stays mostly unearned and the stock loses one of its main supports.
The August 27 earnings report is the next concrete test.
