AI semiconductor revenue climbed 221% to $16.7 billion and increased 54% sequentially as hyperscaler demand for custom accelerators and networking continued to expand. The strong growth was not enough to lift the stock. AVGO fell about 6% as investors focused on a $34.8 billion Q4 revenue forecast that came in slightly below consensus and a projected decline in gross margin to approximately 73%. The reaction highlighted a growing tension between Broadcom's rapidly expanding AI business and the lower margins associated with its changing semiconductor mix. --- ### Key Points - Broadcom's fiscal Q3 revenue increased roughly 86% to $29.59 billion, while AI semiconductor revenue surged 221% to $16.7 billion. - Q4 revenue guidance of $34.8 billion came in slightly below consensus, while gross margin is expected to decline to approximately 73% as AI accelerators become a larger part of the revenue mix. - Broadcom expects approximately $115 billion in AI revenue in fiscal 2027 and sees a path to roughly $230 billion in fiscal 2028, supported by demand from six XPU customers. --- ## Broadcom’s AI Semiconductor Business Accelerates Broadcom's fiscal Q3 results showed how rapidly artificial intelligence has changed the company's revenue mix. Semiconductor Solutions revenue increased 127% year over year to $20.84 billion, while AI semiconductor revenue reached $16.7 billion. That represented growth of 221% from a year earlier and 54% from the previous quarter. Broadcom expects the acceleration to continue in Q4\. AI semiconductor revenue is projected to reach $21.7 billion, representing growth of more than 236% year over year. The company expects both XPU and AI networking revenue to triple from the prior-year period. Custom accelerators are playing an increasingly important role. Broadcom is delivering Ironwood TPU v7 to Anthropic and Google in high volume and has begun production shipments of TPU v8i to Google. The company also shipped Jalapeño, OpenAI's first-generation custom accelerator, and expects production shipments of Meta's MTIA accelerator during Q4. CEO Hock Tan said demand from Broadcom's six XPU customers continues to accelerate. The company has secured enough supply to support approximately $115 billion in AI revenue during fiscal 2027 and sees a path to roughly $230 billion in fiscal 2028. Together, those forecasts represent approximately $350 billion in AI semiconductor revenue across the two fiscal years. ## Why Did AVGO Stock Fall Despite Strong AI Growth? The stock market reaction centered on expectations rather than a deterioration in AI demand. Broadcom expects Q4 revenue of approximately $34.8 billion, up 93% year over year. That forecast was slightly below consensus estimates of roughly $35.03 billion to $35.05 billion provided in the source material. Semiconductor revenue is expected to reach $26.1 billion, increasing 136%, while infrastructure software revenue is projected at $8.7 billion, representing growth of approximately 24% to 25%. Despite those growth rates, AVGO stock fell about 6%. Investors had been positioned for a larger near-term forecast increase following Broadcom's rapid AI expansion. The broader semiconductor reaction was comparatively contained. Nvidia (NVDA) traded higher, while Advanced Micro Devices (AMD) and Marvell Technology (MRVL) moved lower. The iShares Semiconductor ETF was down about 1%, compared with Broadcom's substantially larger decline. The divergence suggests the market was responding particularly closely to Broadcom's guidance and margin outlook rather than treating the results as evidence of weaker AI infrastructure demand across the sector. ## Margin Compression Becomes Broadcom’s Next Test Broadcom's accelerating AI revenue is changing the economics of its semiconductor business. Fiscal Q3 gross margin was approximately 75%, down 210 basis points sequentially. Broadcom expects consolidated gross margin to decline further to approximately 73% in Q4, compared with 78% in the same quarter a year earlier. Management attributed the decline to the increasing mix of XPUs with greater memory content. As custom AI accelerators become a larger portion of revenue, the additional memory required by those products is diluting Broadcom's consolidated gross margin. The company is also considering physical supply constraints when determining its AI forecasts. Leading-edge wafers, substrates and high-bandwidth memory are among the factors that can influence how quickly customer deployments proceed. Operating profitability has held up better. Broadcom's Q3 operating margin reached 67.9%, increasing 240 basis points year over year, and the company expects an operating margin of approximately 66% in Q4. Free cash flow reached $13.7 billion in Q3, representing 46% of revenue. The combination creates a key financial dynamic: AI is producing exceptional revenue growth while simultaneously increasing the proportion of lower-gross-margin products within Broadcom's business. --- ## What It Means for Investors Broadcom's fiscal Q3 report separates two important questions about its AI business. The first is demand. On that measure, the company reported substantial growth and provided significant forward visibility. AI semiconductor revenue increased 221% in Q3, Q4 AI revenue is expected to reach $21.7 billion, and management sees approximately $115 billion in fiscal 2027 followed by roughly $230 billion in fiscal 2028. The second question is how that growth translates into profitability. Broadcom's gross-margin outlook is moving lower as custom accelerators with greater memory content become a larger portion of revenue. Supply availability also remains important. Management said demand exceeds the approximately $115 billion of AI revenue it expects to support in fiscal 2027, making supply rather than customer demand a constraint on the outlook. Broadcom's next results will therefore provide additional evidence on several connected issues: whether AI semiconductor revenue reaches the $21.7 billion Q4 target, how gross margins develop as the XPU mix increases, and whether available supply continues supporting the company's longer-term AI revenue expectations. ## Conclusion Broadcom's latest results showed exceptionally rapid AI semiconductor growth, but the market's reaction demonstrated that growth alone was not enough to satisfy expectations. Fiscal Q3 revenue rose roughly 86% to $29.59 billion, AI semiconductor revenue increased 221% to $16.7 billion, and management outlined approximately $350 billion of potential AI semiconductor revenue across fiscal 2027 and fiscal 2028. At the same time, Q4 total revenue guidance came in slightly below consensus, while gross-margin guidance fell to approximately 73% as custom AI accelerators and their higher memory content become more prominent. The result is a more complex AI growth story. Broadcom has substantial demand visibility across multiple hyperscaler customers, but investors are now receiving clearer evidence of the margin and supply-chain tradeoffs accompanying that expansion. --- ## FAQs ### Why did Broadcom stock fall after earnings?
