Why Is Broadcom Stock Up Premarket Today? Google Signals Higher AI Investment

Broadcom Inc. (AVGO) shares surged 5.62% in premarket trading on February 5, 2026, reaching $325.35 at 5:42:18 AM EST, following Alphabet’s quarterly earnings report that revealed a dramatic acceleration in AI infrastructure spending. Google announced expectations to spend as much as $185 billion on capital expenditures in 2026, nearly double the prior year’s investment, with much of this funding directed toward AI data centers.

Broadcom stands to benefit significantly as a key partner in manufacturing Google’s custom tensor processing unit (TPU) chips, which power the tech giant’s advanced AI models including the state-of-the-art Gemini 3.

The premarket rally represents a sharp reversal from the previous day’s close at $308.05, down 3.83%, and signals renewed investor confidence in Broadcom’s strategic positioning within the AI semiconductor ecosystem.

Google’s AI Capex Outlook Lifts Semiconductor Suppliers

The premarket surge in Broadcom shares directly correlates with Alphabet’s announcement of aggressive AI infrastructure investments during its February 4, 2026 earnings call. Unlike many technology companies that rely on industry-standard Nvidia chips for AI workloads, Google develops proprietary tensor processing units that offer optimized performance for its specific AI applications.

Broadcom plays an essential role in this ecosystem by providing the semiconductor expertise and intellectual property necessary to manufacture these custom TPUs, positioning the company as an indispensable partner in Google’s AI strategy.

Ben Reitzes, Melius Research head of technology research, characterized Google’s capital expenditure guidance as “an incredible number” that represents a significant boon for Broadcom and other companies tied to Alphabet’s technology infrastructure. The analyst emphasized that the spending figures exceeded expectations and would directly benefit what he termed the “Google cohort” of semiconductor suppliers.

Broadcom’s burgeoning custom chip business, which focuses on application-specific integrated circuits (ASICs), has been developing what the company calls “XPUs” for five separate hyperscale customers, though Google and Anthropic remain the only publicly named clients.

The partnership between Broadcom and Google extends beyond basic chip manufacturing. In December 2025, Broadcom announced it would sell Google’s TPU Ironwood rack systems to Anthropic, another artificial intelligence laboratory, demonstrating the breadth of Broadcom’s positioning within the AI hardware market.

This arrangement showcases how Broadcom serves not only as a manufacturing partner but also as a distribution channel for Google’s AI infrastructure, creating multiple revenue streams from a single partnership. The company’s involvement in custom AI chips positions it uniquely among semiconductor firms, as only the most sophisticated hyperscalers possess the resources and technical expertise to develop proprietary AI accelerators.

Broadcom Stock Gains as AI Optimism Returns

As of the February 4, 2026 close, Broadcom maintained a market capitalization of $1.461 trillion with a trailing P/E ratio of 67.11, reflecting investor expectations for continued growth driven by AI demand. The stock trades significantly below analyst consensus, with a 1-year target estimate of $458.59 representing substantial upside potential of approximately 49% from current levels.

Recent analyst activity includes a January 15, 2026 upgrade from Wells Fargo, which raised its price target from $410 to $430 while maintaining an Overweight rating, citing strong positioning in the AI enterprise market.

The company’s financial performance demonstrates robust fundamentals, with trailing twelve-month revenue of $63.89 billion and a profit margin of 36.20%. Broadcom generated $25.04 billion in levered free cash flow over the past year, providing substantial resources for research and development investments critical to maintaining its competitive position in custom AI chips.

The company’s return on equity of 31.05% significantly outpaces many semiconductor peers, reflecting efficient capital deployment and strong business execution across both its Semiconductor Solutions and Infrastructure Software segments.

Despite the recent volatility, with the stock down 10.99% year-to-date before the premarket surge, Broadcom has delivered exceptional long-term returns, posting gains of 39.74% over one year, 439.12% over three years, and 627.59% over five years. These returns substantially outperform the S&P 500 across all time periods, validating the company’s strategic pivot toward AI-focused semiconductor solutions.

Analyst recommendations remain overwhelmingly positive, with consensus ratings showing strong buy sentiment and Susquehanna serving as the top-ranked analyst with a positive rating and an 81/100 score for accuracy.
