Shares of Marvell Technology (NASDAQ:MRVL | MRVL Price Prediction) are up 13% to $243.66 in early Wednesday trading after the company disclosed a warrant issued to Alphabet‘s (NASDAQ:GOOGL) Google worth about $12.18 billion, tied to a broader deal to develop custom AI chips for Google. Marvell stock is rebounding off a sharp Tuesday slide and extending an already outsized 155% year to date (YTD) advance through Tuesday’s close.
Broadcom (NASDAQ:AVGO) shares are down 3% to $369.13 on the same headline. The move highlights the competitive stakes in Google’s custom AI chip roadmap, where Broadcom has been the incumbent supplier for multiple generations of tensor processing units.
The clean read for investors: Marvell is gaining share on a marquee hyperscaler program, and Broadcom appears to be giving some up. That’s why the reaction reads as a zero sum shift rather than an industry rising tide.
Google Warrant Reshapes the Custom Silicon Race #
Marvell stated Wednesday that it issued Google a warrant to buy a stake worth about $12.18 billion, part of a broader agreement to help develop custom chips for the hyperscaler. The warrant is a right to buy, not an equity position Google currently holds, and specific share count, strike, and vesting terms were not disclosed.
Under the deal, Marvell will develop AI inference accelerators, storage, networking and memory interface controllers, and near memory computing technologies for Google. Demand for custom silicon such as Google’s TPUs has surged as businesses seek alternatives to expensive general purpose graphics processors.
Broadcom signed a long term agreement with Google in April to develop and supply future generations of custom AI chips and other components for Google’s next generation AI racks through 2031. That existing relationship is why Broadcom stock is under pressure on Marvell’s announcement, even though the two vendors could, in theory, share different portions of the same TPU stack.
Peer Reaction Splits Along Custom Silicon Lines #
Alphabet shares are unchanged at $342.67, with the stock up 10% YTD through Tuesday’s close. The market is treating the warrant as a supplier reshuffle rather than a strategic pivot at Google, and the flat reaction lines up with a broadly neutral sentiment backdrop on the name.
Astera Labs (NASDAQ:ALAB) shares are up 1% to $307.42, recovering a portion of Tuesday’s 5% slide. Astera Labs stock remains up 82% YTD as AI data center connectivity names continue to draw capital tied to hyperscaler buildouts.
Credo Technology shares are up 3% to $252.85, extending a YTD gain of 71%. The Marvell versus Broadcom divergence is the sharpest signal of the morning, and connectivity plays like Credo and Astera Labs are typically read as adjacent beneficiaries of any custom silicon ramp.
Semiconductor ETF Reflects the Equal Weight Effect #
The SPDR S&P Semiconductor ETF is up 1% to $521.50 in early Wednesday trading. The fund uses an equal weighted methodology, so mid cap custom silicon and connectivity names like Marvell, Astera Labs, and Credo carry more weight than they would in a market cap weighted chip index.
That structure cuts both ways. It amplifies gains on days when the custom silicon narrative wins, and it concentrates sector risk if hyperscaler capital expenditure plans slow or if a single program shifts vendors. Sizing sector exposure through this ETF should weigh that concentration against the broader diversification of a market cap weighted alternative.
What to Watch #
Marvell’s next quarterly report is confirmed for Wednesday, August 27, after the market close. Traders may want to keep an eye on whether management contextualizes the Google warrant with specific customer bookings commentary, and whether Broadcom stock stabilizes ahead of its own September earnings report.
Shareholders can watch for clarifying disclosures on the warrant’s share count, strike, and vesting, none of which accompanied Wednesday’s announcement. The headline dollar figure alone is enough to redraw the map of who supplies Google’s next generation TPU stack, and today’s split reaction across Marvell, Broadcom, and Alphabet stock is likely just the opening move.
