Broadcom Hits $2 Trillion Market Cap as Google Reveals New AI Chips

Authored by Leo Miller. Date Posted: 4/28/2026.

As Broadcom (NASDAQ: AVGO) has surged to new all-time highs, it has a key partner to thank: Google’s parent company, Alphabet (NASDAQ: GOOGL).

On April 22, the semiconductor giant reached what was then a record closing high near $422. Broadcom briefly eclipsed a $2 trillion market capitalization that day.

For a moment…

Forget about Trump’s ties to Israel.

Forget about reports of Iran’s nuclear program.

Because my research has led me to believe we’re risking World War 3 with Iran for a completely different reason.

The move followed a new artificial intelligence (AI) chip announcement from Google, Broadcom’s largest customer. The stock rose about 5% on the news, although shares have traded down slightly since.

Google’s announcement reinforces Broadcom’s previous predictions and suggests the relationship between the companies is only deepening.

Google’s 8th Gen TPU: 2 Chips Instead of 1

Google co-develops its tensor processing units (TPUs) with Broadcom; the two have partnered on the technology for roughly a decade. Now Google has announced the eighth generation of its TPU lineup with an important distinction.

The eighth generation will feature two chips instead of one, each specialized for a different use case, according to Google. This marks a notable shift: most prior TPU generations consisted of a single chip. Google says TPU 8t will be a “training powerhouse,” while TPU 8i will be a “reasoning engine” for the most latency-sensitive inference workloads.

Google’s announcement closely matches comments Broadcom CEO Hock Tan made earlier. In the company’s last earnings call, Tan said customers will “start to develop two chips each year simultaneously, one for training, one for inference to be specialized.” Those remarks came in early March. For Broadcom, that alignment is a meaningful win for several reasons.

Why Google’s 2-Chip Roadmap Benefits Broadcom

First, by splitting the eighth-generation TPU into two chips, Broadcom stands to benefit more as general AI adoption grows. Adoption often translates into increased inference usage — AI models answering questions and performing tasks. With a specialized inference chip in TPU 8i, Google can scale inference workloads more efficiently.

Google notes TPU 8i delivers 80% better performance per dollar versus the seventh-generation TPU, enabling businesses to serve nearly twice the inference volume at the same price. Lower costs should boost inference demand, which in turn would increase demand for the chips themselves — a clear positive for Broadcom.

Moreover, moving to two specialized chips elevates the importance of Broadcom’s hardware expertise. Software optimizations can improve single-chip deployments, but the gains from hardware-level optimization are typically much greater. Google’s two-chip approach reflects that trade-off.

That shift away from software-only tuning and toward hardware specialization plays to Broadcom’s strengths and could let the company capture more value per chip.

Developing two chips also requires more engineering work than developing a single device. Broadcom is likely to be compensated for that added effort, which could translate into higher design-related revenue.

Finally, Google’s announcement is another data point supporting Hock Tan’s comments. Meta Platforms (NASDAQ: META), another Broadcom customer, revealed its custom chip roadmap in mid-March titled “Four MTIA [Meta Training and Inference Accelerator] Chips in Two Years: Scaling AI Experiences for Billions.” That roadmap aligns with the two-chips-per-year framework, and the Google and Meta announcements together lend credibility to Broadcom’s expectations.

Broadcom says it sees similar two-chip-per-year roadmaps across five customers. With Google and Meta already confirming this approach, confidence grows that the other hyperscalers may follow, potentially spreading the benefits across Broadcom’s broader customer base.

Broadcom Soars as Hyperscaler Earnings Approach

Overall, Broadcom is showing that customers are deepening their relationships with the company. As investors recognize Broadcom’s growing role in the AI buildout, shares have moved to unprecedented levels.

At the same time, Broadcom trades at a lower forward price-to-earnings (P/E) ratio than in the recent past. If earnings expectations align more closely with the stock’s valuation, Broadcom may be better positioned to hold recent gains or move higher.

A potential slowdown in hyperscaler AI spending remains a risk, though it has not materialized so far. Upcoming earnings from several Magnificent Seven companies should provide more clarity on the spending outlook.
