Broadcom's Guidance Miss Overshadows a 221% AI Beat as Anthropic Deepens Its Bet
Broadcom reported fiscal third-quarter revenue of $29.6 billion Wednesday, up 86% year-over-year and above the $29.43 billion Wall Street expected, with adjusted earnings of $3.32 per share topping the $3.24 consensus, per the company's release. AI semiconductor revenue grew 221% year-over-year and 54% sequentially to $16.7 billion, and Broadcom raised its full-year AI revenue view to $58 billion from $56 billion. The disappointment was the forecast: fourth-quarter revenue guidance of roughly $34.8 billion came in just below the $35.0 billion-plus Wall Street had modeled, per Reuters, sending shares down as much as 5% in initial after-hours trading before paring to a 0.82% after-hours decline at $364.23, per CNBC; the stock was still down roughly 3.8% in Thursday's premarket to $353.30.
"Anthropic is on track to become our largest XPU customer in 2027 and sustain that in 2028." — Hock Tan, President and CEO, Broadcom, via BenzingaTan's line is the financial mechanics behind the miss-and-still-bullish setup: Broadcom is deploying 1 gigawatt of Ironwood TPU capacity for Anthropic this year, expects another 5 gigawatts of the newer TPU v8i in 2027, and sees a further 10 gigawatts of potential Anthropic deployments in 2028, even as production shipments of Google's TPU v8i have already begun. Broadcom's own guidance implies fiscal 2027 AI revenue near $115 billion and a doubling again to $230 billion by fiscal 2028, with management targeting more than $30 in earnings per share that year. But Barron's noted the immediate stock reaction was also about competitive noise: concerns over data-center financing structures and Google's parallel custom-chip relationship with Marvell overshadowed the solid print. For portfolio managers, Wednesday's session is a reminder that even a 221%-growth AI quarter isn't immune to a guidance number landing a few hundred million dollars short of the Street's highest expectations.

Companies & Financials
Microchip and GlobalFoundries Chase the Edge Beyond the AI-Compute Race
- Microchip Technology and Marelli unveiled a joint automotive display-connectivity solution built on the open ASA Motion Link standard, letting a vehicle's central computer stream graphics and video directly to displays at data rates up to 16 Gbps, per the companies' announcement. Why it matters: the push toward open, interoperable automotive architectures comes as Wall Street has been cutting Microchip's price targets — Wells Fargo to $88, TD Cowen to $90 — on elevated channel inventory, making software-defined-vehicle design wins a needed offset to that overhang.
- GlobalFoundries announced customer availability of its new UX platform CMOS technologies, 40UX and 22UX, aimed at edge AI, sensing and connectivity applications, with 40UX ramping at its Singapore site in 2027 and 22UX manufactured in Dresden, per the company. Why it matters: the launch is GlobalFoundries' bid to capture "Physical AI" edge-device demand outside the leading-edge race dominated by TSMC and Samsung, the same differentiation thesis Stifel cited this week in initiating the stock at Buy.

Samsung Narrows the HBM Gap With SK Hynix as Micron's Taiwan Unions Near a Strike Vote
- Samsung Electronics' HBM revenue share jumped to 33% in the second quarter from 21%, narrowing its gap with leader SK hynix to 17 percentage points from 37, while Micron's share slipped 3 points to 18%, according to Counterpoint Research, per the Seoul Economic Daily. Why it matters: Samsung booked $1 billion of HBM revenue within four months of starting HBM4 mass production in February, ahead of every rival, and also leads the overall DRAM market at 38% share — evidence its combined DRAM-and-HBM franchise is compounding faster than SK hynix's more HBM-concentrated model.
- Micron's Taiwan unions are seeking a one-off bonus worth roughly 83 months of salary per employee for fiscal 2026, plus a switch to quarterly payouts equal to 15% of operating profit starting fiscal 2027, with a strike vote possible this month if mediation fails, per The Motley Fool. Why it matters: more than 80% of surveyed union members backed strike action, and Micron's Taiwan site feeds its HBM and DRAM output for AI customers — a labor dispute stacking directly on top of the pricing cycle that has powered the stock's gains this year.
Supply Chain, Equipment & Fabs
TSMC's Tool Orders Nearly Double as Packaging Becomes the New AI Cost Center
- TSMC's equipment purchase needs have climbed to 1.9 times its original December projection, up from 1.5 times as of the first quarter, even as full-year capex guidance rose only about 15% at the midpoint to a $60 billion-$64 billion range, deputy co-COO Cliff Hou said at Semicon Taiwan, per Tom's Hardware. Why it matters: the gap between near-doubled tool demand and a far smaller capex increase suggests TSMC is negotiating harder on price even as it races to keep pace with AI-driven capacity needs — and the foundry has acknowledged it still cannot meet all customer demand.
- Advanced packaging, assembly and testing now account for 75% of the cost of an Nvidia B200 accelerator once memory is excluded, MediaTek general manager T.Y. Lau said at the 3DIC Global Summit during Semicon Taiwan, per Digitimes. Why it matters: the figure underscores why packaging capacity at TSMC, ASE and Amkor has become as strategically important to AI-chip economics as leading-edge wafer capacity, reshaping where in the supply chain the next pricing power is likely to concentrate.
Policy & Geopolitics
Lutnick's Tariff Ultimatum Meets a Rising Chinese Threat to Samsung and SK Hynix
- Commerce Secretary Howard Lutnick said Samsung Electronics and SK hynix are effectively "on notice" to build U.S. chip plants or pay tariffs, contrasting their lack of new U.S. investment since the Trump administration took office with more than $500 billion in combined commitments from TSMC ($265 billion) and Micron ($250 billion), per the Seoul Economic Daily. Why it matters: Lutnick said U.S. chip-production share must rise to 50% from about 1% by the end of the administration's term and floated a pharmaceutical-style tariff model — no duty during construction, steep duties after — turning the threat into a direct capital-allocation decision for Korea's two largest chipmakers.
- China's ChangXin Memory Technologies topped a 10% share of the global DRAM market for the first time in the second quarter, up from below 1% in 2023 and 8% in the first quarter, as it filled the commodity-DRAM gap left by Samsung and SK hynix's pivot to HBM, per the Seoul Economic Daily, citing Counterpoint Research. Why it matters: CXMT is now mass-producing DDR5 and LPDDR5/5X and pushing toward HBM3E, with more than 63% of its first-half revenue from outside mainland China — a competitive threat compounding the tariff pressure Washington is applying to Samsung and SK hynix at the same time.
Analyst Corner
SemiAnalysis Sees Nvidia Winning Korea's AI Bet as BMO Turns Bolder on Broadcom
- SemiAnalysis (Max Kan, Ray Wang, Myron Xie and Dylan Patel, September 1): the research house argued that Nvidia has likely secured a long-term SOCAMM supply agreement plus favorable HBM pricing and volume commitments from SK hynix for 2027 as part of Korea's trillion-dollar sovereign-AI buildout, concluding the arrangement benefits Nvidia more than it benefits Hynix shareholders.
- BMO Capital (via TheFly, September 2): the firm raised its price target on Broadcom to $575 from $455 while keeping an Outperform rating, citing sales that came in slightly ahead of expectations even as the stock fell on guidance that undercut the market's highest hopes.
Calendar / Week Ahead
Arm's Pay Vote and TSMC's Monthly Sales Are the Next Data Points for Chip Investors
- Tuesday, Sept. 9 — Arm Holdings holds its annual general meeting, where shareholders vote on chief executive Rene Haas's roughly $800 million pay package after proxy advisers ISS and Glass Lewis recommended against it, per Tom's Hardware.
- Thursday, Sept. 10 — TSMC releases its August monthly sales figures, the market's most current real-time read on AI-driven foundry demand between quarterly earnings reports, per TSMC's investor financial calendar.
