Alphabet’s AI Spending Spree Is Fueling Broadcom’s Next Big Rally

Alphabet (NASDAQ:GOOG | GOOG Price Prediction)(NASDAQ:GOOGL) reported fourth-quarter earnings that exceeded analyst estimates, with full-year revenue exceeding $400 billion for the first time ever. However, the tech stock’s guidance for 2026 capital expenditures, ranging from $175 billion to $185 billion — nearly double the $91.4 billion spent in 2025 — raised concerns about profitability amid intense AI infrastructure demands. 

This outlook triggered a volatile stock reaction, with shares dropping over 6% initially in after-hours trading, recovering to a 2% gain during the earnings call, and closing down about 2% overall. The stock is now down 8% in morning trading. The announcement also briefly pressured broader market futures as investors weighed the implications of escalating Big Tech spending. Yet there is a silver lining to the dark cloud Alphabet is casting, and that’s Broadcom (NASDAQ:AVGO).

Broadcom’s Direct Gains from Alphabet’s AI Push

Broadcom stands to benefit significantly from Alphabet’s aggressive capital spending plans, given its established role as a supplier in Google’s Tensor Processing Unit program. The company’s custom AI chips, or XPUs, are integral to handling AI workloads in data centers, and analysts forecast that shipments related to Google’s TPUs could reach 7 million units by 2028, potentially driving Broadcom’s AI ASIC revenue to $78.4 billion in 2027. With Alphabet’s capex focused on scaling AI compute and infrastructure, including servers and networking, Broadcom’s semiconductor solutions align directly with this demand. 

In its own fourth-quarter report, Broadcom’s AI semiconductor revenue reached $6.5 billion, up 74% year-over-year, underscoring its exposure to hyperscaler investments like Alphabet’s. This positions Broadcom to capture a portion of the estimated 50% increase in data-center capital spending projected for 2026.

Broadcom’s Broader AI Semiconductor Dominance

Beyond its ties to Alphabet, Broadcom has become a central player in the AI-driven semiconductor market. The company expects its AI chip revenue to grow 100% year-over-year in the first quarter, reaching $8.2 billion. This projection reflects accelerating demand for custom silicon from major clients, with overall revenue anticipated to rise 52% to $96 billion in fiscal 2026. 

Analysts estimate earnings of $10.29 per share for the year, supported by a $162 billion backlog, including at least $73 billion over the next 18 months. Broadcom’s semiconductor segment, which grew 35% to $11.1 billion in Q4, benefits from its focus on high-performance AI accelerators and networking chips. The company’s adjusted EBITDA margin is expected to hit 67% in Q1, highlighting its efficient scaling during a period of explosive AI growth.

Wi-Fi 8 Launch Boosts Networking Edge

The recent launch of Broadcom’s Wi-Fi 8 platform further strengthens its position in AI-integrated networking. Earlier this week, Broadcom introduced the industry’s first enterprise-grade Wi-Fi 8 access point and switch solution, powered by the BCM49438 accelerated processing unit. This system incorporates AI acceleration, security, and analytics to handle multi-gigabit traffic in AI-ready networks. 

Last month, Broadcom unveiled a unified Wi-Fi 8 platform for residential use, featuring the BCM4918 processor and BCM6714/BCM6719 devices to support bandwidth-intensive AI applications like AR/VR and smart homes. These innovations address the need for low-latency, high-throughput connectivity in AI ecosystems, and position Broadcom to capitalize on enterprise and consumer demand for efficient networking solutions.

Key Takeaway

Broadcom remains attractively priced with a forward price-to-earnings ratio of about 21, a discount considering its projected 52% revenue growth in fiscal 2026. Analysts are forecasting revenue reaching $130 billion in fiscal 2027, with earnings at $14.22 per share. Profits are expected to follow a similar trajectory, rising 50% this year, 40% next year, and 37% over the next five years.

Growth tailwinds, including sustained AI semiconductor demand, a robust backlog, and innovations like Wi-Fi 8, provide Broadcom with momentum that can drive its stock performance even amid market uncertainties. Although its stock is down 11% in 2026, driven lower by expected margin pressures from its backlog growth, it presents investors with a buy-in opportunity for a chipmaker that can still shine despite the clouds.
