Broadcom holds $73B backlog

Broadcom put two numbers on the table in recent quarters that explain why investors are treating its AI business less like a standard semiconductor cycle and more like a booked-order business. On March 4, 2026, Chief Executive Hock Tan said the company had “line of sight” to AI chip revenue “in excess of $100 billion” in 2027. Three months earlier, on Dec. 11, 2025, Tan said Broadcom held $73 billion of AI backlog to be delivered over the next 18 months. Those disclosures came as Broadcom’s AI revenue accelerated. Broadcom reported fiscal first-quarter 2026 AI semiconductor revenue of $8.4 billion, up 106% from a year earlier, and guided to about $10.2 billion to $10.7 billion for the following quarter, according to the company’s earnings materials and reporting on the March call. (fool.com) The customer list also became clearer. CNBC, citing Tan’s March comments, said Broadcom’s six key custom-chip customers included Google, Meta, Anthropic and OpenAI, with Fujitsu and ByteDance likely the other two. Reuters reported the March forecast as evidence of rising demand for custom AI chips as large technology companies seek alternatives and complements to Nvidia’s systems. (fool.com) ### Where does the $73 billion figure come from? Dec. 11, 2025, is the date Broadcom attached the backlog number to its AI hardware business. On that earnings call, Tan said the company expected “this $73 billion in AI backlog” to be delivered over the next 18 months. Transcript services carrying the call said the figure covered AI orders already booked rather than a broad pipeline of possible future deals. (cnbc.com) That matters because backlog is narrower than total demand. Broadcom’s wording tied the number to scheduled shipments, which gives investors a more concrete measure of near-term revenue visibility than customer discussions or design wins alone. That reading is an inference from the company’s delivery timetable and reported backlog language, not a separate company definition. (fool.com) ### Who is buying these chips? Google has been Broadcom’s longest-running custom AI silicon partner. CNBC reported that Google began developing tensor processing units with Broadcom in 2015 and has offered those chips to cloud customers since 2018. Anthropic emerged as a named buyer in December 2025. (fool.com) CNBC reported that Broadcom said Anthropic was the previously unnamed customer behind a $10 billion order for Google TPUs, and that Tan said Anthropic was using Google’s Ironwood TPU. Meta and OpenAI are also central to the story. Tan said in March that Meta’s MTIA roadmap was “alive and well,” according to the earnings-call transcript, while CNBC reported that Broadcom was assisting OpenAI on custom in-house processors, though Tan said he did not expect much revenue from that partnership in 2026. (cnbc.com 1) (cnbc.com 2) ### Why does Broadcom talk about “custom” chips instead of standard GPUs? Broadcom’s role is different from Nvidia’s merchant-chip model. Reuters and CNBC described Broadcom as helping large customers design custom accelerators and then supporting the process that turns those designs into manufactured silicon through foundry and packaging partners. (fool.com) March 4 was the first time Broadcom publicly framed that business at the scale of a three-digit-billion revenue target. Tan told analysts the company had secured the supply chain needed to reach the 2027 goal, while the earnings transcript said Broadcom had fully secured component capacity through 2028. (cnbc.com) ### What should investors watch next? Broadcom’s next earnings report is the next hard checkpoint. The company’s June 5, 2025, release shows its practice of updating quarterly AI revenue and near-term guidance in formal results announcements, and investors will be looking for the same detail on backlog conversion, customer concentration and 2027 visibility in the next call. That expectation is based on Broadcom’s recent disclosure pattern. (cnbc.com) A second marker is whether the named customer set expands again. Broadcom used its December 2025 and March 2026 calls to add detail on Anthropic, OpenAI and the six-customer framework, and any future filing or earnings call from Hock Tan could show whether the $73 billion backlog is being replenished as shipments move through 2026.
