Marvell Stock Jumps 9.9% on Google AI Chip Deal as Broadcom Falls 4.6%

Marvell Technology shares surged after the semiconductor company disclosed an expanded custom-chip partnership with Google, giving the chipmaker a larger role in the infrastructure supporting Google’s artificial intelligence processors.

Marvell stock closed Wednesday up 9.9% at $237.27 after trading as high as $246.90. Broadcom, Google’s established partner for its Tensor Processing Units, fell 4.6% to $362.48 as investors assessed whether the new arrangement could redirect some future business toward Marvell. Alphabet shares finished almost unchanged.

Key Takeaways

• Marvell will develop multiple custom semiconductor products connected to Google’s TPU ecosystem.
• Google received a warrant to buy almost 59 million Marvell shares at $206.58 each.
• Most warrant shares vest only when Google purchases qualifying products, potentially linking Marvell to as much as $120 billion in cumulative revenue thresholds.
• Broadcom fell 4.6%, although its existing agreement to develop Google TPUs runs through 2031.

Marvell Expands Its Role in Google’s TPU Ecosystem

According to a regulatory filing, Marvell and Google signed the commercial agreement on July 29. The partnership covers a broad collection of custom chips designed to operate alongside Google’s TPU infrastructure.

The products include AI inference accelerators, storage controllers, network-interface controllers, memory-interface controllers and near-memory computing technology. These components help move, store and process information throughout large AI computing clusters.

Google’s TPUs are internally designed accelerators created specifically for artificial-intelligence workloads. The company initially used them primarily inside its own data centers, but TPU-powered computing has become an increasingly important part of Google Cloud’s offering to outside customers.

The agreement therefore gives Marvell exposure not only to Google’s internal AI investment but potentially to the wider adoption of TPU infrastructure by cloud customers and artificial-intelligence developers.

However, Marvell’s filing describes the new products as attaching to the TPU ecosystem. It does not state that Marvell has replaced Broadcom as the principal manufacturer or development partner for Google’s core TPU processors.

Google Receives a Performance-Linked Marvell Warrant

Alongside the commercial agreement, Marvell issued Google a warrant to purchase as many as 58,970,907 Marvell shares at an exercise price of $206.58. Exercising the entire warrant at that price would require approximately $12.18 billion.

The warrant does not represent an immediate $12.18 billion investment by Google. Its shares must first vest, and most are tied directly to future purchases of qualifying Marvell products.

A total of 1,360,867 shares will vest in equal quarterly installments during the first year. The remaining shares are divided into 240 tranches, with one tranche vesting for every $500 million in qualifying revenue generated from Google or its affiliates between Marvell’s fiscal third quarter of 2027 and the end of fiscal 2033.

That structure mechanically creates as much as $120 billion in cumulative revenue milestones. It should not be interpreted as a guaranteed $120 billion order, however, because the filing describes Google’s purchases as discretionary.

The warrant expires on August 18, 2033. If the arrangement reaches its upper thresholds and Google exercises the vested warrants, it could become one of Marvell’s largest shareholders. The structure aligns Google’s financial upside with the amount of business it directs toward Marvell, while also exposing existing investors to potential share dilution.

Why Broadcom Stock Fell 4.6%

Broadcom’s decline reflected concern that Google is diversifying a custom-silicon supply chain that has historically depended heavily on Broadcom.

The market reaction does not necessarily indicate that Broadcom has lost its core Google business. In April, Broadcom disclosed a long-term agreement to develop and supply future generations of Google’s TPUs. It also agreed to provide networking and other components for Google’s next-generation AI racks through 2031.

The two arrangements could therefore be complementary. Broadcom may continue developing the principal TPU processors and networking platforms, while Marvell supplies additional accelerators, controllers and memory-related products surrounding those processors.

Analysts also argue that Google’s AI infrastructure requirements are expanding quickly enough to support multiple custom-chip suppliers. Adding Marvell could increase production capacity, reduce dependence on one vendor and give Google greater leverage over pricing and product development.

Nevertheless, the equity-linked incentive could gradually shift Google’s purchasing priorities. The more qualifying Marvell products Google buys, the greater the number of warrants it earns, giving the cloud company a financial reason to expand the relationship.

Marvell Strengthens Its Custom-Silicon Position

The agreement reinforces Marvell’s ambition to become a major supplier of customized AI infrastructure rather than relying primarily on traditional networking and storage chips.

Hyperscale cloud operators increasingly design specialized processors because custom chips can deliver better performance and power efficiency for specific workloads than general-purpose hardware. Marvell helps translate those internal designs into manufacturable silicon while supplying the connectivity, memory and optical technology required to operate large computing clusters.

The company already works with major cloud customers and has expanded its capabilities through the acquisition of Celestial AI, which specializes in photonic connectivity for moving data between processors.

Marvell’s 9.9% rally shows that investors view the Google partnership as validation of this strategy. The stock also moved back above its 50-day moving average ahead of Marvell’s quarterly earnings report scheduled for August 27.

Investors will now look for management’s estimates of the partnership’s near-term revenue contribution, expected development costs and potential margin profile. They will also want clarity on which products are already under development and how quickly the revenue-linked warrant milestones could begin vesting.

For Broadcom, the key issue is whether Marvell represents an additional supplier within a rapidly expanding Google ecosystem or the beginning of a longer-term redistribution of custom-chip orders. Wednesday’s contrasting share moves priced in the competitive risk, but the existing contracts suggest Google may ultimately need both companies to support its AI ambitions.
