Broadcom's $230 billion AI promise is rented from six customers, and the stock trades like it

Hock Tan opened the 2 September earnings call↗ with records in revenue, operating income and free cash flow ¹. Fiscal third-quarter revenue hit $29.59 billion, up 86 percent, and $16.7 billion of it was AI silicon, up 221 percent ²³. Tan drew the AI curve out to $115 billion in fiscal 2027 and $230 billion in 2028 ¹². The stock sits near $353 anyway, 29 percent under its high ⁴.

Six balance sheets pay the toll

Every dollar on that curve is rented from six custom-chip customers: Google, Meta, OpenAI, Anthropic, ByteDance and Fujitsu ⁵. Google's TPU agreement runs through up to 2031, "multi-tens of billions of dollars" of processors a year in Tan's words ¹⁶. Anthropic deploys 1 gigawatt of Ironwood this year and 5 gigawatts of TPU 8i in 2027, with 10 more in line of sight, enough to become Broadcom's largest XPU customer ¹²⁶.

OpenAI's Jalapeno shipped in the quarter, a second-generation chip is at tape-out, and Meta's MTIA accelerator enters production shipments ¹². Apple is a seventh balance sheet, but not an XPU one: a $30 billion-plus commitment through 2031↗ for custom silicon, wireless and the networking around its late Baltra server chip ⁷.

At $20 billion to $30 billion of Broadcom content per gigawatt, the gigawatts are the forecast ¹. The $230 billion is not a chip forecast; it is a forecast about six balance sheets.

The escape went on sale on 24 September

Google has begun selling TPUs beyond its own cloud, turning the escape from Nvidia's margin into a merchant product ⁸. Broadcom started TPU 8i production shipments on 2 September and expands volume this quarter ⁸. Morgan Stanley sizes direct TPU sales at $84 billion in 2027 and $108 billion in 2028↗, and Piper Sandler put 2028 at $104 billion on 28 September↗ ⁸⁹. On Piper's math, the Anthropic gigawatts alone imply $105 billion in 2027 and $210 billion in 2028 if the capacity gets built ⁹.

Beijing found the meter

China's state-asset regulator spent weeks surveying state-backed data centers↗ and found Broadcom switches in as much as 90 percent of them; informal guidance to scale back may follow, the treatment that already bars Nvidia ¹⁰¹¹. Management has put AI networking near 40 percent of AI semiconductor revenue ⁵. Alibaba's Zhenwu V900 and Huawei's Ascend 960 are racing to fill China's compute gap ¹².

The discount is the ledger

The other side of the trade sits with shareholders. The stock is up about 6 percent in 2026 against the S&P 500's 12 percent, on earnings roughly 43 percent higher than where January started ²⁴. The average analyst target is $533, half again the price ⁴. That looks like a discount for growth a handful of customers can cancel and a regulator can meter, though nothing splits the 29 percent among concentration, Beijing and AI-capex nerves.

What closes the gap

The bulls have receipts. Q2 bookings ran $30 billion against $10.8 billion shipped, and supply, not demand, is the binding constraint ⁴⁵. Two verdicts land within weeks: the fiscal Q4 print against a $34.8 billion guide sitting slightly under consensus, and SASAC's ruling in Beijing ²⁴¹⁰. The third runs longer: whether the residual-value guarantees Broadcom may extend to the labs stay, in the finance chief's words, low risk ¹.
