Broadcom shares dropped roughly 12% in premarket trading on Thursday after quarterly revenue came in below market forecasts, undermining investor hopes for a faster acceleration tied to the artificial intelligence market. At the reported premarket price of $418.83, the decline could translate into a loss of more than $285 billion in market capitalization if the move holds.
Investors are closely watching a narrow group of chipmakers for leadership in AI workloads. Broadcom now faces heightened comparison with Nvidia, whose graphics processors continue to be regarded as the benchmark for AI tasks. The pullback in Broadcom's stock reflects the market's sensitivity to anything less than substantial upside in the current AI-driven rally.
Analysts and market commentators pointed to the gap between expectations and results. Matt Britzman, senior equity analyst at Hargreaves Lansdown, described the share selloff as "a classic case of very high expectations meeting a market that wanted perfection," and said investors are punishing results that fall short of what they wanted.
Management response and guidance
Broadcom's chief executive, Hock Tan, raised the company's shipment forecast for AI chips to more than 10 gigawatts in 2027, while maintaining the firm's longer-term objective of $100 billion in AI revenue. Despite reiterating these ambitious targets, some analysts said the lack of higher near-term guidance disappointed investors conditioned to see "material beats and raises" from leading names in the sector.
TD Cowen analysts said that restating prior AI revenue targets without increasing them in a market expecting stronger near-term outperformance is likely to disappoint, and that the quarter leaves "lingering questions" around execution and ramp timelines.
Supply, demand and competitor dynamics
Broadcom executives acknowledged pressure elsewhere in the semiconductor supply chain, noting that surging memory chip prices amid a supply crunch have strained the broader industry. They also said the company is "very comfortable" after securing supply for 2026 and 2027.
Nevertheless, investor confidence was further shaken by the company's downbeat outlook for third-quarter AI chip revenue, reinforcing concerns that demand may be solid but that revenue growth could be slower to accelerate than markets anticipated.
Competition in custom AI silicon is also intensifying. Rivals such as Marvell Technology are expanding their custom chip initiatives and strengthening relationships with hyperscaler customers. Marvell's shares were reported down about 4% in response to the evolving competitive landscape.
Financials and valuation context
Broadcom's core AI semiconductor business still showed strong year-on-year growth, with AI semiconductor revenue up 143% to $10.8 billion for the quarter. On a valuation basis, Broadcom traded at 29.90 times forward earnings estimates, compared with Marvell's 61.70 multiple and the S&P 500's 27.94 multiple, according to LSEG data.
