Broadcom shares jumped 10.3% Monday as investors bet big on the chipmaker's deepening partnership with Google's AI infrastructure. The rally comes as analysts lift price targets, seeing Broadcom as the hidden winner behind Google's custom chip strategy that's been quietly building since 2016.
Broadcom just had its best trading day in seven months, and it's all about a partnership that most investors overlooked until now. The semiconductor giant surged 10.3% Monday as Wall Street finally woke up to its critical role in Google's AI infrastructure buildout.
The rally wasn't random. Alphabet shares climbed over 5% as the AI trade regained momentum, dragging Broadcom along for what analysts are calling a "derivative play" on Google's AI dominance. But this isn't just about riding coattails - Broadcom has been Google's exclusive partner for custom AI chips since 2016, a relationship that's now hitting serious scale.
Here's what investors are betting on: Google processes an insane amount of data through its custom tensor processing units (TPUs), and Broadcom designs and manufactures every single one of them. These aren't off-the-shelf chips - they're application-specific integrated circuits (ASICs) built specifically for Google's AI workloads, competing directly with Nvidia's GPUs.
The numbers tell the story. Google's token processing jumped from 480 trillion in April to 1,300 trillion in October, according to Jefferies analyst Blayne Curtis. That's nearly a 3x increase in eight months, and Curtis expects it to keep climbing as Google rolls out multimodal AI models that need even more compute power.
"Google has long been the main ASIC customer for AVGO but those volumes should become much more meaningful in C26/27," Curtis wrote in a November 3rd research note. He's got the highest price target on Broadcom among all analysts tracking the stock, lifting it to $480 last week - implying another 41% upside from current levels.
Melius Research's Ben Reitzes is equally bullish, bumping his target to $475 in October. His take? Google and Broadcom's custom ASIC partnership is "now starting to inflect to the upside," delivering growth for both Broadcom's AI revenues and Google Cloud's expansion. "Outside of the Nvidia GPU for AI workloads, the TPU is the most proven ASIC out there," Reitzes told clients.
The timing couldn't be better for Broadcom. Google just announced its seventh-generation TPU called "Ironwood," along with new AI advances like Gemini 3 and its "Google Antigravity" agent platform. Each breakthrough means more demand for the custom silicon that only Broadcom can deliver at Google's scale.
But here's what makes this partnership unique: it's not just about current volumes. Reitzes believes other hyperscalers are watching Google's success and want "a piece of this design expertise." That could mean Broadcom's ASIC business expands beyond Google to Amazon, Microsoft, and other cloud giants building their own custom chips.
The market is pricing in exactly that scenario. Broadcom has gained 60% year-to-date, making it the top performer in the Technology Select Sector SPDR fund that tracks S&P 500 tech stocks. Monday's surge put the stock on pace for its best single day since April 9, when the company last delivered earnings that beat expectations.
What investors are really betting on is Broadcom's moat in custom chip design. Building ASICs isn't like manufacturing memory or processors - it requires deep engineering partnerships and years of iteration. Google and Broadcom have been refining their TPU designs for nearly a decade, creating switching costs that make it nearly impossible for competitors to break in.
The broader AI infrastructure theme is also heating up. While everyone focuses on Nvidia's GPU dominance, companies like Google are proving that custom silicon can deliver better performance and economics for specific workloads. That's a huge opportunity for Broadcom, which has the design expertise and manufacturing scale that hyperscalers need but can't build themselves.
Broadcom's rally reflects a deeper shift in AI infrastructure, where custom chips are becoming as important as general-purpose GPUs. With Google's token processing tripling in months and other hyperscalers eyeing similar custom silicon strategies, Broadcom sits at the center of a trend that's just getting started. The question isn't whether this partnership will grow - it's how many other cloud giants will want their own version of what Google and Broadcom have built together.
