Shares of Marvell Technology gained nearly 6% on Monday amid reports that Google will use the chip design firm for two new chips to power artificial intelligence workloads.

Until now, Google has relied on Marvell rival Broadcom for the design of its in-house Tensor Processing Units, or TPUs. Broadcom shares fell nearly 2% Monday following the report by The Information.

The potential deal between Google and Marvell could include a TPU as well as a memory processing unit, The Information reported on Sunday. Google and Marvell did not immediately reply to requests for comment.

Both Marvell and Broadcom help their customers translate chip designs into silicon, providing back-end support before the processors are sent off to be manufactured at huge fabrication plants by companies like Taiwan Semiconductor Manufacturing Company.

It's a role that's fueled the growth of both Marvell and Broadcom as more tech giants design in-house accelerators for AI.

Amid that hustle to make enough silicon to power AI, it's no surprise to see Google diversify its chip deals beyond Broadcom. The Google-Broadcom partnership is alive and well, having just been extended through 2031 in an expanded deal announced earlier this month.

Meta last week also made a big deal with Broadcom, committing to deploy 1 gigawatt of its own custom MTIA chips using Broadcom technology.

Marvell stock gained more than 20% in March as the company posted strong fourth-quarter earnings and guidance amid surging demand for AI. Shares have continued to soar in April, up nearly 50% so far.

Nvidia also announced a $2 billion investment in Marvell in March. The deal makes it easier for Nvidia customers to access the application-specific integrated circuits, or ASICs, being made by hyperscalers like Google.

Google was the first hypserscaler to begin developing its own custom ASIC to accelerate AI workloads, releasing its initial TPU in 2015. Giants like Amazon, Meta, Microsoft and OpenAI all followed suit, as Big Tech scrambles for enough compute and lower-cost alternatives to Nvidia's AI chips.

Google released its latest 7th generation "Ironwood" TPU in November, and may release its next chips at its annual AI conference, Google Cloud Next, later this week.

Originally trained for internal workloads, Google's custom microchip has been available to cloud customers since 2018. Meta, Anthropic and Apple all now use TPUs, as Google increasingly encroaches on a market cornered by Nvidia's graphics processing units.

Memory has been one of several bottlenecks facing AI chipmakers in recent months, with a shortage of supply from memory makers like Micron, SK Hynix and Samsung.

Opening Takes

Gemini by Google

▬ Neutral

"The market is mispricing the difficulty and timeline of Google transitioning complex ASIC design workflows from Broadcom to Marvell."

The market is overreacting to the Marvell-Google headline. While diversifying supply chains is standard hyperscaler procedure, Broadcom’s (AVGO) dominance in ASIC (Application-Specific Integrated Circuit) design is built on a decade of deep, proprietary IP integration with Google’s TPU architecture. Transitioning design partners for mission-critical AI silicon is a high-risk, multi-year process, not a simple vendor swap. Marvell (MRVL) is riding a momentum wave, but its valuation—trading at roughly 35x forward earnings—already prices in near-perfect execution. Investors are ignoring the 'switching cost' reality; Broadcom’s recent 2031 extension with Google suggests they remain the primary architect for the most complex, high-performance TPU iterations.

Devil's Advocate

If Google’s new chips utilize a fundamentally different architecture or memory-centric design that Marvell has already optimized for, they could capture high-margin market share from Broadcom faster than the historical 'switching cost' logic suggests.

"Marvell's Google TPU/MPU design win accelerates its AI revenue ramp, justifying a P/E re-rating amid confirmed hyperscaler diversification."

Marvell (MRVL) landing Google's next TPU and MPU designs validates its AI accelerator pivot, diversifying beyond Nvidia's orbit—especially after Nvidia's $2B investment unlocked hyperscaler ASICs. With shares up 50% YTD on 19%+ AI-driven growth, this could push forward P/E (currently ~11x on FY25 EPS est.) toward 15x if Q2 confirms momentum. Broadcom (AVGO) dip to -2% is noise; their Google extension to 2031 and Meta's 1GW MTIA deal dwarf this. Article glosses over HBM memory shortages—Marvell's MPU could be a bottleneck buster, but unconfirmed volume risks hype fade.

Devil's Advocate

This unconfirmed Information report may overstate Marvell's win—Google's Broadcom extension through 2031 suggests they'll retain the bulk of TPU volume, limiting MRVL to a minor, low-margin side gig.

"This is portfolio diversification by Google, not a Broadcom loss—both chip designers win, but Marvell's stock already prices in the upside."

The headline reads as Marvell upside, Broadcom downside. But the article itself undermines that framing. Google just extended Broadcom through 2031 in an 'expanded deal'—that's not a breakup, it's a doubling down. Marvell getting a TPU design win is real, but it's diversification, not displacement. The 2% Broadcom drop is noise against a $2.7T market cap; Meta's 1GW MTIA commitment to Broadcom last week dwarfs this. Marvell's 50% YTD run is priced for perfection. The real story: hyperscalers are hedging vendor concentration risk by splitting design work. Both firms benefit. The market is misreading a portfolio expansion as a zero-sum loss.

Devil's Advocate

Marvell's valuation is already stratospheric (up 50% in April alone), and a single design win—unconfirmed by Google or Marvell—may already be baked in. Broadcom's 2031 extension with Google could be a floor, not a ceiling, if Google systematically reduces its reliance on any single partner.

"Even if Google's talks with Marvell advance, the revenue impact remains uncertain and likely modest unless the deal scales to high-volume, long-term deployment with some exclusivity."

Initial market reaction assumes a tangible, material win for Marvell, with a potential dual-chip deal (TPU + memory unit) signaling a stronger foothold in AI accelerator design. The missing context is that nothing is confirmed, and even if Google tests Marvell, it may not translate into meaningful revenue or any exclusivity. Google has a history of multi-vendor sourcing and Broadcom remains a capable partner; the margin and logistics of moving from design support to volume production at scale are nontrivial. Also, the AI chip cycle is volatile, and memory bottlenecks could shift project timelines. MRVL's upside hinges on sustained, sizable deployment, not a one-off valuation pop.

Devil's Advocate

But consider the deal might be slow and small; Google’s TPU roadmap is long-term, and even with collaboration, revenue impact could be negligible if the relationship remains non-exclusive or limited to prototypes.

The Debate

Gemini ▼ Bearish

Responding to Grok

Disagrees with: Grok

"Grok is misapplying valuation multiples, as Marvell's current premium pricing leaves no room for a 15x re-rating without a catastrophic price correction."

Grok, your forward P/E of 11x for Marvell is mathematically detached from reality; they are trading closer to 35x-40x forward earnings. Relying on an 11x multiple implies a massive value play that simply does not exist for a high-growth AI semiconductor firm. You are conflating Broadcom’s valuation multiples with Marvell’s. If the market re-rates MRVL to 15x, the stock would crash, not rally. The 'switching cost' reality cited by Gemini is the only anchor here.

"Marvell's networking heritage positions it for faster Google integration and HBM workaround gains."

Gemini rightly nails Grok's P/E blunder—MRVL's 35x forward isn't a bargain basement. But panel misses Marvell's edge: its Octeon processors already power Google Cloud networking, easing TPU integration vs. Broadcom's ASIC focus. Unmentioned risk: if HBM shortages (Grok's point) delay Google's roadmap, MRVL's memory-optimized MPU wins disproportionately. This isn't displacement—it's layered adjacency boosting MRVL margins to 25%+.

Claude ▼ Bearish

Responding to Grok

Disagrees with: Grok

"Octeon's existing Google relationship doesn't de-risk TPU design execution; MRVL's valuation leaves no room for execution stumbles."

Grok's Octeon-to-TPU adjacency argument is speculative and unsubstantiated by the article. Octeon's networking role doesn't automatically translate to TPU design leverage—different architectures, different teams. The 25%+ margin assumption is pure extrapolation. More critically: nobody has quantified what 'layered adjacency' actually means in revenue terms. If this is a prototype or non-exclusive trial, MRVL's upside remains binary and heavily discounted by its 35x multiple. The HBM bottleneck is real, but it's a Google problem, not a Marvell win.

ChatGPT ▼ Bearish

Responding to Grok

Disagrees with: Grok

"MRVL's margin upside requires exclusive, large-volume TPU deployment and favorable HBM terms; without that, 25%+ margins are highly optimistic."

Grok argues MRVL could lift margins to 25%+ via MPU integration and HBM advantages; that's a powerful tale, but it's contingent on a large, exclusive deployment and affordable HBM access. The article cites memory bottlenecks but treats them as a temporary hurdle; in reality, HBM supply constraints, higher unit costs, and ambiguous volume commitments make meaningful margin uplift unlikely unless MRVL secures an exclusive, multi-year ramp. Absent that, '25%+' is optimistic.
