Broadcom's AI Revenue Surge Outpaces Market Expectations

Broadcom’s fiscal 2026 third-quarter results demonstrate a significant acceleration in demand for its custom application-specific integrated circuits and networking processors. The company reported revenue of $29.6 billion, an 86% increase year-over-year, driven primarily by its semiconductor segment. Non-GAAP earnings nearly doubled to $3.32 per share, reflecting improved operational leverage as volumes scaled.

The AI chip business was the primary growth engine, with revenue surging 221% to $16.7 billion in the quarter. However, the stock traded lower following the announcement on Sept. 2, as the company guided for fourth-quarter revenue of $34.8 billion, slightly below Wall Street’s consensus estimate of $35.1 billion. This minor divergence between actual performance and analyst expectations highlights the high bar set for the firm's continued expansion.

Q4 Guidance Exceeds Prior Year Baseline

For the upcoming fiscal fourth quarter, Broadcom projects total revenue growth of 93% year-over-year. Within this, AI-related revenue is expected to rise 236% to $21.7 billion. This guidance indicates that the pace of adoption for its custom silicon remains robust, with hyperscalers and AI-native cloud providers continuing to integrate Broadcom’s networking and computing solutions into their infrastructure buildouts.

The company’s performance in the first nine months of fiscal 2026 generated $35.9 billion in AI revenue. Including the guided fourth-quarter figure, total AI revenue for fiscal 2026 is projected to reach $57.6 billion, representing an 186% increase over the prior fiscal year. This trajectory confirms that custom silicon is becoming a central component of large-scale data center architectures.

Multi-Year Supply Secured for 2028

Management has outlined a long-term growth path that extends beyond the current fiscal cycle. Broadcom estimates that AI revenue will double in fiscal 2027 to $115 billion and reach $230 billion in fiscal 2028. On the earnings call, executives stated that the company has secured sufficient supply to meet its fiscal 2028 outlook, addressing potential bottlenecks in the semiconductor supply chain.

The firm also expects earnings per share to exceed $30.00 in fiscal 2028. This projection is supported by the continued expansion of its customer base in AI infrastructure. According to GN stocks/chips, these figures suggest that Broadcom’s growth is not merely a short-term cyclical spike but is underpinned by multi-year contracts and strategic partnerships with major technology firms.

Macro AI Capex Supports Demand

The broader context for Broadcom’s growth is the massive capital expenditure by major hyperscalers. Nvidia has noted that the combined capital expenditure of the top five hyperscalers is poised to reach $800 billion in 2026, potentially rising to $1.3 trillion in 2027. Industry estimates suggest total AI capital expenditure could reach $3 trillion to $4 trillion by 2030.

While the PHLX Semiconductor Sector index has risen 97% over the past year, Broadcom has lagged due to valuation concerns and the recent guidance miss. However, the company’s ability to secure supply for 2028 and its position in the custom ASIC market provide a distinct competitive advantage. The divergence between its current stock price and its long-term revenue trajectory suggests that the market may be undervaluing the durability of its AI-driven growth.
