Broadcom reported Q2 fiscal 2026 results on June 3, posting record consolidated revenue of $22.2 billion (+48% YoY) and AI semiconductor revenue of $10.8 billion (+143% YoY), per the company's 8-K. CEO Hock Tan guided Q3 AI semi revenue to $16 billion (+200% YoY) and reiterated the full-year fiscal 2026 AI target at $56 billion (+180% YoY). The stock fell in after-hours trading because the FY guide was held rather than raised.
The number that explains the reaction is $56 billion held flat from prior commentary. Sell-side AI semi consensus had drifted to roughly $58-60 billion ahead of the print, anchored on Q1 momentum and the implied Q4 exit-rate from the new Q3 guide. When Tan stuck with $56 billion, traders read that as Broadcom signaling Q4 deceleration rather than continued ramp. The math: $10.8B Q2 plus $16B Q3 guide is $26.8B for those two quarters alone, leaving roughly $29 billion to come from Q1 plus Q4 to hit $56B. Q1 was already reported, so Q4 implied at the new run rate sits below Q3. That is the part of the print AI-trade desks objected to.
The non-AI semi line is the other read. Broadcom's legacy networking, broadband, and storage chip lines are growing in the single digits, which means the AI mix is climbing toward 50% of the semi segment. That concentration is a margin win and a customer-concentration risk in the same move. Hyperscaler ASIC programs (Google TPU, Meta MTIA, Microsoft Maia) are the bulk of Broadcom's AI revenue, and any single program slipping a quarter ripples directly through the headline.
Bottom Line
A 143% Q2 print is the cleanest AI semi beat of the cycle, and the after-hours selloff is consensus learning the run rate has a ceiling close to the upside case. Q4 is now the swing on Broadcom's full-year story.
