Quick Read

  • Broadcom (AVGO) and Marvell (MRVL) design custom AI chips costing between $6 billion and $11 billion per gigawatt, compared to $19 billion for Nvidia GPU racks.

  • Hyperscalers will spend over $1 trillion on AI next year, with Google alone adding more compute than all four combined did in 2025.

  • This lithium producer surpassed a $1B private valuation, joining some of America's most powerful startups. Now you can invest in EnergyX alongside global giants like General Motors, but only through July 16. (sponsor)

Broadcom and Marvell Are Bigger Threats to Nvidia Than You Know

Nvidia (NASDAQ:NVDA | NVDA Price Prediction) remains the undisputed leader of the AI chip market, but leadership and dominance are not the same thing. The next phase of the AI buildout is shifting from buying the fastest hardware available to lowering the cost of operating AI at hyperscale. 

Alphabet (NASDAQ:GOOG), Amazon (NASDAQ:AMZN), Meta Platforms (NASDAQ:META), and Microsoft (NASDAQ:MSFT) are all pursuing custom silicon alongside Nvidia’s GPUs because every percentage point of efficiency matters when spending tens of billions of dollars annually on AI infrastructure. 

That trend doesn’t eliminate Nvidia’s advantage, but it does create a growing opportunity for the companies designing those custom chips—most notably Broadcom (NASDAQ:AVGO) and Marvell Technology (NASDAQ:MRVL).

The Battle Is Moving From Training to Cost Efficiency

Nvidia still owns AI training. Its GPUs remain the gold standard for developing frontier models, and its CUDA software ecosystem continues to give it a competitive moat. But this is where the market is changing.

Once models are trained, they spend years handling inference — answering prompts, generating images, and powering AI applications. Those workloads don’t always require Nvidia’s most powerful processors. They often reward lower costs and higher efficiency instead. That is where application-specific integrated circuits, or ASICs, enter the picture.

Broadcom has become the leading partner helping hyperscalers build custom AI accelerators, while Marvell has carved out a similar niche with customers including Amazon. Rather than selling chips under their own brands, they help cloud providers design silicon optimized for their own software and infrastructure.

Morgan Stanley says hyperscalers continue to expand their investments in proprietary silicon to improve total cost of ownership and reduce dependence on merchant GPU suppliers.

The opportunity for Broadcom and Marvell is enormous. The analyst says Google, Amazon, Microsoft, and Meta are forecast to spend over $1 trillion on AI infrastructure next year, adding 19.5 gigawatts (GW) of incremental compute capacity. In 2025, they added roughly 6.7 GW. Google alone will add 6.8 GW, or more than the hyperscalers did combined two years ago.

The Economics Are Becoming Harder to Ignore

The appeal of custom silicon comes down to dollars. Milk Road AI estimates that building one gigawatt of AI infrastructure using Broadcom- or Marvell-designed ASIC racks cost between $6 billion and $11 billion, compared with roughly $19 billion using Nvidia GB300-based racks. Under Vera Rubin, rack costs jump to $25 billion. It illustrates why hyperscalers are increasingly willing to invest years designing their own chips.

Surprisingly, this isn’t an either-or decision for hyperscalers. Google continues developing Tensor Processing Units with Broadcom while still purchasing enormous numbers of Nvidia GPUs. Amazon follows a similar strategy with Trainium alongside Nvidia deployments.

That diversification gives cloud providers leverage in negotiations while matching the right chip to the right workload.

Nvidia Is Still Winning — But Watch the Suppliers

Granted, Nvidia is hardly standing still. The company continues expanding beyond GPUs into networking, rack-scale systems, and software while opening technologies such as NVLink Fusion to custom silicon partners — including Marvell itself.

That said, investors sometimes underestimate where the fastest incremental growth may occur. Every new custom AI accelerator designed by Google, Meta, Amazon, or another hyperscaler creates another opportunity for Broadcom or Marvell. They benefit whether customers build proprietary chips instead of buying more off-the-shelf processors, and they are standing directly in the path of a massive $1 trillion spending tsunami.

In other words, Nvidia remains the king of AI compute, but Broadcom and Marvell are increasingly becoming the architects behind the industry’s second act.

Key Takeaway

In short, investors shouldn’t mistake Nvidia’s dominance for exclusivity. The AI infrastructure market is expanding so rapidly that multiple winners can emerge. Nvidia still commands the premium end of AI computing, particularly for training, but custom silicon is becoming an essential part of every hyperscaler’s long-term strategy. Broadcom appears best positioned today thanks to its deep relationships with Google and Meta, while Marvell continues strengthening its foothold with Amazon and other large customers. 

Ultimately, investors looking beyond today’s GPU boom may find that the companies quietly designing tomorrow’s AI chips offer just as compelling a long-term opportunity.
