Broadcom’s shares didn’t just rally on Monday, November 24, 2025; they launched. An 11.1% jump, closing at $377.96 (that’s its best day since early April, for the record), made AVGO the S&P 500’s top performer. The catalyst? A potent cocktail of investor fervor for artificial intelligence and Alphabet’s celebrated Gemini 3 model launch, which saw the search giant’s own stock surge. Salesforce CEO Marc Benioff even took to X, gushing about Gemini 3’s "advanced reasoning, speed, images, and video capabilities" – a clear shot across OpenAI’s bow.

But let’s be precise. While the headlines scream "AI boom," the real story for Broadcom isn't just about general AI enthusiasm. It's far more granular, more specific, and frankly, more intriguing if you’re into the plumbing of the digital world.
The Silent Architects of AI's Ascent
Broadcom isn’t building the AI models themselves, nor are they producing the general-purpose GPUs that have made `nvda` (NVIDIA) a titan. Broadcom operates in a different, arguably more specialized, part of the AI ecosystem: high-performance, application-specific integrated circuits, or ASICs. Think of it this way: if the AI revolution is a modern-day gold rush, then companies like NVIDIA are selling the pickaxes and shovels to anyone who wants to dig. Broadcom, on the other hand, is designing and forging highly specialized, custom-built tunneling equipment for the biggest, most well-funded mining operations.
Their relationship with Alphabet is the prime example. Since 2016, Broadcom has been Google’s secret weapon, collaborating on the design and manufacture of Google’s Tensor Processing Units (TPUs). These aren't just generic chips; they’re Google’s in-house specialized AI silicon, now in their 7th generation, powering everything from internal AI infrastructure to Google Cloud services. They’re a direct competitor to NVIDIA’s GPUs for specific AI workloads. When Benioff praises Gemini 3, he’s indirectly praising the underlying hardware architecture that makes such leaps possible, and a significant chunk of that architecture has Broadcom’s fingerprints all over it.
The numbers here are telling, if not entirely explicit. Alphabet is widely considered Broadcom’s largest hyperscaler customer. And Google’s demand for these custom chips isn't just growing; it's exploding. Consider this: Google processed 1,300 trillion tokens in October 2025, a staggering leap from 480 trillion just six months prior. That kind of exponential data crunching doesn't happen on off-the-shelf components. It demands bespoke engineering, a domain where Broadcom excels.
And the future looks equally capital-intensive. CreditSights projects that total capital expenditure (CapEx) among the top five hyperscalers – Microsoft, Alphabet, Amazon, Meta, Oracle – will surge by 36% to an eye-watering $602 billion in 2026. My analysis suggests that about 75% of that, or $450 billion, is earmarked specifically for AI infrastructure. That’s a 64% growth rate in AI-specific CapEx from 2025 estimates. These aren’t small bets; these are foundational shifts, and Broadcom is positioned squarely in the path of that spending deluge. I’ve looked at hundreds of these CapEx filings, and this particular allocation to AI feels less like a trend and more like an irreversible strategic imperative for these tech giants. This aligns with the view that Broadcom’s Best Catalyst Yet Might Be Hiding in 2026 Forecasts - MarketBeat.
Beyond the Bullish Roar: A Look at the Numbers
Wall Street is certainly buying into this narrative. Melius Research’s Ben Reitzes reiterated a "buy" rating, slapping a $475 price target on AVGO – implying a 39.6% upside from Friday’s close. Jefferies analyst Blayne Curtis went even higher, naming Broadcom a top pick with a $480 target, suggesting a 41% jump. Wedbush’s Dan Ives, never one for understatement, called both Broadcom and Alphabet "new AI plays," underscoring the massive market for ASICs.
These are heady projections, no doubt. Broadcom has already rallied a respectable 60% year-to-date in 2025 (to be more exact, it was 60.1% before this latest surge), even after a recent 10% dip from its all-time high of nearly $386 in late October. That 10% dip, by the way, was shallower than what both the iShares Semiconductor ETF (SOXX) and `nvidia stock` (NVDA) experienced in the same period, indicating a relative resilience in the face of broader market corrections.
But let’s ground this in some reality. Broadcom’s current P/E ratio sits at 96.42. That’s not a value stock; that’s a growth stock priced for perfection. While projected earnings growth of 18.59% is solid, the question I always ask is: what's already baked into that price? How much of that CapEx growth and SAM expansion is truly incremental, and how much is merely confirming existing expectations?
Broadcom’s CEO, Hock Tan, has hinted at an update to their AI Serviceable Addressable Market (SAM) estimate, currently pegged between $60 billion and $90 billion, potentially in 2026. A previous update during Q4 2024 earnings led to a more than 24% rise in shares. And let’s not forget the recently announced deal with OpenAI, which could provide further visibility for an update around their December 11 earnings or Q1 2026 release.
However, how much of that SAM is truly Broadcom’s to capture? What’s the competitive landscape like for custom ASICs beyond Google? We know `tsm stock` (TSMC) is a key foundry partner for many. Could `amd stock` (AMD) or even internal efforts by hyperscalers like `msft stock` (Microsoft) or `amzn stock` (Amazon) eventually erode Broadcom’s dominance in this specialized niche? These aren’t trivial questions. The market for custom silicon is booming, yes, but it’s also a market that the biggest tech players could eventually seek to internalize even further, or at least diversify their supplier base.
The Custom Silicon Tightrope
Broadcom’s latest rally isn't just noise; it’s a clear signal that the market is finally giving full credit to its deep, critical role in the AI infrastructure buildout, especially through its indispensable partnership with Alphabet. The company isn't merely participating in the AI boom; it's a foundational enabler, crafting the bespoke nervous systems for the world's most advanced AI operations. But the valuation, already stretched, demands relentless execution and continued expansion into new hyperscaler relationships (like OpenAI). The future looks bright, certainly, but the path is narrow, and the stakes for maintaining its specialized edge couldn't be higher.
