Broadcom's AI Chip Guidance Miss Wipes $1.3 Trillion From Markets
Broadcom's below-estimate AI chip revenue forecast triggered a $1.3 trillion semiconductor sector selloff on June 5, 2026.
"Broadcom grew AI revenue 100% year-over-year and still got punished. That's how unforgiving the AI hype premium has become."
Broadcom shares cratered on June 5, 2026 after CEO Hock Tan projected Q3 AI semiconductor revenue of $16 billion — missing analyst expectations of $17.2 billion. The company's full-year AI chip forecast of $56 billion also fell short of the $57.6 billion consensus, despite Broadcom posting a solid fiscal Q2 with $22.19 billion in total revenue and non-GAAP EPS of $2.44, both beating estimates. AI-specific revenue surged over 100% year-over-year to $10.8 billion, with custom chip customers including Google, Meta, Anthropic, and OpenAI.
The guidance miss detonated across the broader semiconductor sector. The SOXX ETF collapsed 10.44%, the PHLX semiconductor index dropped 8.5%, and the Nasdaq fell 4.18% — its steepest single-day decline since April 2025. Arm Holdings shed 12.8%, Intel 11.3%, AMD 10.9%, and Nvidia 6%. The S&P 500 lost 2.64%, closing at 7,383.
A Macquarie analysis added structural concern: Broadcom's revenue share of Alphabet's tensor processing units is projected to fall from 95% in 2026 to 65% by 2028. Bernstein's Stacy Rasgon offered a counterpoint, noting Broadcom is still growing revenues and EPS above 50% — but markets priced in the miss, not the momentum.
Even one guidance miss in AI infrastructure can trigger sector-wide repricing, signaling that investor expectations have outpaced actual demand curves. Executives budgeting AI capital expenditure should monitor chip supply forecasts as leading indicators of enterprise AI buildout pace. The Alphabet TPU share erosion also signals intensifying competition in custom silicon that could reshape vendor relationships across the AI stack.
